antivirus software

Antivirus software program is a vital a part of our digital life. The extra we’re creating on this area of know-how the extra we’re falling prey to hackers and rogue software program. 

An excellent antivirus software program can shield your information and save your useful money and time in flip. 

What is Computer Virus: 

A PC /laptop virus is a software program normally hidden inside  other malicious programs that may produce copies of itself and insert them into different program and operating system software which in a long run performs a dangerous action of valuable data loss.

An instance of it is a PE an infection, a ion way, normally used to unfold malware, that inserts further information or executable code into a portable executable file  installed in your system

What is Malware: 

Malware is any software program deliberately designed to trigger harm to a Computer/Laptop, server, shopper, or community wan /lan computers. 

All kinds of malware types exist, together with Compute viruses, high end worms, dangerous Trojan horses, some ransomware,  witty spyware and adware, rogue software program, and unnecessary scare-ware. 

Find out how to detect virus/malware 

All kinds of malware sorts exist, together with pc viruses, worms, Trojan horses, ransomware, spyware and adware, adware, rogue software program, and scareware. 

Various Identification Strategies: 

There are a number of strategies which antivirus engine can use to determine malware: 

The Sandbox detection method: 

a specific behavioural-based detection method that, as a substitute of detecting the behavioural fingerprint at run time, it executes the applications in a digital setting, logging what actions this system performs. 

Depending on the logs registred, the antivirus engine can decide if the computer or laptop software is malicious or not

If not, then, this system is executed in the actual setting. This method proves to be fairly efficient one , given its weight and slowness. It’s hardly ever utilized in end-user antivirus options

The Knowledge mining methods: 

It is one  of the newest method utilized in malware detection. 

The Knowledge mining and machine learning algorithms methods are used to find out and  classify the behaviour of a file in a computer system.

It is a sequence of file extensions, which might be extracted from the file itself

The Signature-based detection method:

Common types of  antivirus software program depends closely upon signatures to find out  presence of malware inside a computer system

Considerably, when a new malware arrives and investigated by antivirus agency, it’s analysed by malware researchers or by dynamic evaluation techniques

After the investigation, the antivirus company decides it to be a malware or virus. Than a correct signature of the file is being extracted and added to the signatures database of the antivirus software program as new updates of antivirus patches

The Heuristics method: 

 A number of viruses begin as a single hand infection. But gradually mutation or transformations by different  dark attackers, can develop into dozens of barely completely different strains, referred to as variants of a virus

Generic detection refers back to the detection and removing of a number of threats utilizing a single virus definition of a virus

Symantec Antivirus company classifies members of the Vundo Trojan into two distinct classes, one is Trojan -Vundo and another one is Trojan-Vundo-B. 

The Rootkit detection method:

This method includes Anti-virus software programs. The Anti virus programs try to scan for rootkits inside a system

A rootkit is a kind of malware designed to reach quitely inside the system and reach upto administrative-level management over a computer or laptop with out being detected and remain hidden inside a program

Rootkits have the strategy to change the working operating system capabilities of a computer and laptop. In some instances it can tamper with the anti-virus programs and firewall settings of a system and gradually make them ineffective

Rootkits are really very tough to eradicate from an infected system. In some instances a whole system re-installation of the working operating system required to throw it out from infected system. 

The Real-time safety :

The Real-time safety works better and can detect viruses and malware presence in a system. At the time of browsing or accessing online files the scanning procedure , the background guard,  the insider resident defend, auto shield, and various other types of checks with the automated safety procedures and programs are supplied by most antivirus, anti-spyware, and different anti-malware softwares

While inserting a CD, opening an electronic mail, or during online shopping real time scans will help to find out viruses.

Anti-virus and anti-malware software program 

A particular element of anti-virus and anti-malware software program, generally known as an on-access or real-time scanner, hooks deep into the working system’s core or kernel and capabilities in a fashion much like how sure malware itself would try to function, although with the person’s knowledgeable permission for shielding the system. 

At the time of  browsing online ,  the AV system accesses a file, the real time access scanner checks the file,  if the file is a ‘really genuine and healthy’ file or not.

If the file is recognized by the system as malware or any sort of virus or any rogue file by the scanner, the operation of opening the file will likely to be stopped. 

The file will than handled by the scanner in a pre-defined and inbuild procedure embeded to remove and cleanse the system. The anti-virus program was configured throughout and gradually submit set up and the person will likely be notified from his windows and desktop icon of antivirus software

This will likely have a substantial efficiency affect on the working system, although the diploma of affect depends on how effectively the scanner was programmed. 

The objective is to cease any operations the malware might try on the system earlier than they happen, together with actions which could exploit bugs or set off surprising working system conduct. 

Anti-malware applications can fight malware in two methods: 

They’ll present actual time safety towards the set up of malware software program on a pc. One of these malware safety works the identical manner as that of antivirus safety in that the anti-malware software program scans all incoming community information for malware and blocks any threats it comes throughout. 

Anti-malware software programs can be utilized by users for detection and removal of malware software program that has already been put in to a computer or laptop through any unknown software

One of these anti-malware software program scans the contents of the Home windows registry, working system information, and put in applications on a pc and can present a listing of any threats discovered, permitting the person to decide on which information to delete or maintain, or to match this listing to a listing of recognized malware elements, eradicating information that match. 

Historical past of Antivirus 

1949–1980 interval (pre-antivirus days) 

1980–1990 interval (early days build up days)

1990–2000 interval (emergence of the antivirus software) 

2000–2005 interval (early time period in antivirus software) 

2005–2014 (Developed period of antivirus software)

In 2007, AV-TEST reported a variety of 5,490,960 new distinctive malware samples in a yr. In 2012 and 2013, antivirus corporations reported a brand new malware samples vary from 300,000 to over 500,000 per day. 

Over time it has change into vital for antivirus software program to make use of a number of completely different methods (e.g. particular electronic mail and community safety or low degree modules) and detection algorithms, in addition to to examine an rising number of information, slightly than simply executables, for a number of cases, 

Highly effective macros utilized in phrase processor purposes, reminiscent of Microsoft Phrase, introduced as a threat. 

Virus writers might use the macros to write down viruses embedded inside a paperwork. 

This means that computer systems might now even be in grave danger from an infection by simply opening paperwork with hidden hooked up macros.

The potential of embedding executable objects inside in any other case non-executable file codecs could make opening these information a threat. Later electronic mail applications, specifically Microsoft’s Outlook Categorical and Outlook, had been susceptible to viruses embedded within the electronic mail physique itself. A person’s pc may very well be contaminated by simply opening or previewing a message In 2005, F-Safe was the primary safety agency that developed an Anti-Rootkit know-how, referred to as Black Gentle. 

2014–on wards (rise of next-gen antivirus software): 

After the 2013 launch of the APT -1 report from Mandiant company, the antivirus companies approach has seen a shifted in the direction of signature-less file finding approach to detect and mitigate zero-day assaults

A number of approaches to handle these new types of threats come to market, together with behavioral detection system, synthetic intelligence system, machine learning, and cloud-based file detection and detonation procedures

More and more, these signature-less approaches have been outlined by the media and analyst corporations as “next-generation” antivirus and are seeing speedy market adoption as licensed antivirus alternative applied sciences by corporations reminiscent of Coalfire and DirectDefense.

Antivirus distributors like Symantec and Sophos have developed “next-gen antivirus” after analyst corporations like Forrester and Gartner referred conventional signature-based antivirus were “ineffective” and “outdated”

Why Antivirus Software

The antivirus is crucial for users of computers and servers as with out antivirus software program safety will likely be diminished and compromised the moment they are online

The virus packages and malware packages are fixed and increasing day by day, as a result antivirus corporations must replace their detection instruments frequently to take care of the greater than 60,000 new items of virus/malware created every day by attackers

At present’s malware (an umbrella time period that encompasses pc viruses) adjustments look shortly to keep away from detection by older, definition-based antivirus software program. 

Viruses program in such a way that trigger harmful effects to your computer/laptop or server. It  stops a person from accessing his own information, or to take conrol and management of your system

An AntiVirus Software program Do the followings:

 A number of completely different corporations construct antivirus software program and what every provide can fluctuate however all carry out some important capabilities: Scan particular information or directories for any malware or recognized malicious patterns Mean you can schedule scans to routinely run for you Mean you can provoke a scan of a specific file or your complete pc, or of a CD or flash drive at any time. 

Guide you and warn you about any malicious code detected in your system. Generally you’ll be notified of an an infection occured or might be occured if you open a file. Also ask your permission and suggest you to clear the  infected file.

Different AV software applications will routinely do these things behind the scenes. They present you the ‘well being’ of your Computer/Laptop or machine and make them virus and malware free.

At all the times you might have the most effective, up-to-date safety software program known as antivirus software that will put in to  the job of guard your computer systems, laptops, tablets, smartphones and servers.

Working of Antivirus Software program  

Many antivirus software program applications nonetheless obtain malware definitions straight to your machine and scan your information in the hunt for matches. However since, as we talked about, most malware repeatedly morphs in look to keep away from detection. 

As an alternative of storing a large amount of virus defination files and examples of acknowledged malware lists in your computer, it shops malware definitions within the cloud

Free Vs Paid Antivirus Software program 

From banking to child pictures, a lot of our enterprise and private information reside on our units. If it had been saved bodily, paying for a safety resolution can be a no brainer. 

Unfortunately, we regularly share our data  and information on-line to stay safe with out lifting a finger or spending a penny. 

However users ought to insist on options like identification theft safety, cellular safety, and assist choices in relation to their information safety, too—options normally missing with free options. 

How corporations provide you free antiviruses?

 There is no such thing as a such factor as a very free antivirus. You all the time “pay” with one thing. Most antivirus companies provide premium variations of their software and restrict the free model software to solely provide some basic safety and scanning only

This leaves a number of loop holes in your systems cyber security protection. 

The corporates by giving you free version actually starts a lead generating process of grabbing customers for their softwares. They will make sure that you’ll acknowledge t their strategy of reporting you’re not well-protected with the use of free virus, and so they’ll attempt to get you to improve to the paid plan by sending you a tons of notifications and ads

Another antivirus corporations even promote free customers’ information to massive firms for advertising functions. 

What are the common viruses that have an effect on your Home Laptop or Computer systems? 

Trojans are normally the common types of  viruses for hackers seeking to infect or steal your private valuable information

These are viruses that looks like different information with extensions like .exe and .doc

However after downloading it, for those who don’t have an antivirus in their PC, turns into a critical virus that might debilitate your machine and probably ship your whole valuable data to a hacker

A good antivirus will warn you from working with that virus/malware in your Computer. A high quality and excellent antivirus will stop you from downloading that virus within the first place itself

Currently top 5 types of free antivirus softwares that you’ll like to trial: 

Right here’s an abstract of free Home windows antiviruses for 2020: 

Avira — Good antivirus know-how with dependable anti-malware safety for many Personal computers. 

Panda — antivirus safety, USB safety, Panda Rescue equipment, Multimedia/ Gaming mode.

Sophos — Finest free plan for households, nice interface with parental controls (as much as three units).

Kaspersky — Free extras like a VPN, dark-web monitoring, and a good password supervisor

Bitdefender — Easy free antivirus which gives you low CPU load

Whereas many manufacturers provide one thing free of charge, there’s an enormous distinction by way of high quality and safety. Most so-called “free antivirus applications” develop into only a virus scan — some applications will detect malware free of charge however demand fee to take away it. 

You need to discover the next options inside a free Home windows antivirus software program and select accordingly: 

Genuinely free and no hidden charges: 

Manufacturers normally attempt to trick you into staying with them by providing a free trial after which making you pay to maintain utilizing the product. 

No surprises after installation: 

I don’t tolerate surprises in relation to on-line safety. Each antivirus right here does what it says it does and doesn’t cover something or mislead you into paying cash. 

Robust safety mechanism:

 Comparatively robust safety mechanism inside the package or not. 

Desired outcomes: 

There are a number of fraud antivirus applications on the market. So take a look at it earlier than totally implement it in your system. 

Extra options:

You’re not going to get the most effective anti virus model with out paying for it. However I’ve given particular consideration to manufacturers that supply just a few further options at no extra money from your pocket. 

I recommend you to go for premium and paid antiviruses as they gives you extra options and actually scan and take away your virus/malware. So don’t go after a free antivirus as your useful information is more valuable than some amount of cash. 

Have a good day.

Li-Fi Technology Everything You Need To Know

Li-Fi Tech

Li-Fi Technology

In this article, we will learn about a new technology the Li-Fi technology. The abbreviation Li-Fi really denotes the term Light Fidelity.

In easy terms, we can say that this Li-Fi technology is nothing but light based wi-fi technology.

And as we know, this Wi-Fi is fully networked, bi-directional wireless communication technology. Where data is being transmitted using the radio waves.

While in the case of Li-Fi technology, the data is transmitted in the form of visible light using the LED light source.

This house hold LED bulbs and LED lamps which are used as a light source can also be used to transmit the data.

First of all, let’s understand how this Li-Fi technology works.

HOW LI-FI TECHNOLOGY WORKS

If you see any LED light source, and you provide the constant current to this LED bulb, it provides the constant illumination or constant brightness.

As we change the current that is flowing through the LED bulb, the illumination or brightness of this bulb will change accordingly.

This principle is used for transmitting the data wirelessly using this Li-Fi technology.

So, if no current or minimum current is flowing through this LED bulb then, the brightness of this LED source will be minimum.

And that will be treated as digital 0. So, digital 0 will be transmitted at the receiver side.

In the same way, when the light bulb is ON, or we can say that if the maximum amount of current is flowing through this LED bulb then the illumination or brightness of the LED bulb will be maximum. And that will be treated as digital 1.

Whenever the LED is ON, it will be taken as digital 1 and will be transmitted at the receiver side.

So, in this way, by flickering the LED light source very rapidly we can transmit the data in the form of 1’s and 0’s to the receiver.

If this flickering is happening at million times per second then we can not see this flickering by our naked eyes.

And we can treat this LED bulb source as normal regular bulb source.

Now let’s see the schematic of Li-Fi transmitter and receiver system.

So, as you can see, the data which is coming from the web server or the internet first it will go to the MODEM, which provides the necessary modulation to the incoming data stream.

Then this modulated data is fed to the LED driver, which changes the driving current for this LED bulb according to the incoming streaming data.

At the receiver end, if you see, the optically received data is first converted into the electrical signal using the photo receiver or photo diode.

And after the signal conditioning, this data is being fed to the computer or laptop.

So, to receive this incoming data, at the receiver side we require the Li-Fi dongle, which consists of photo receiver as well as IR transmitter.

Now this infrared transmitter can be used to transmit the uplink data back to the LED source.

Now, one such company which provides the complete Li-Fi solution is Pure LiFi. It generally makes these Li-Fi dongles.

 

 As we know, how this Li-Fi technology works, now let’s see the advantages of this Li-Fi technology over the other wireless communication technologies.

ADVANTAGES OF Li-Fi

Some of the advantages of the Li-Fi technology over the other wireless communication technologies are as follows:

SPEED:

let’s start with speed of Li-Fi technology.

So far the researchers have achieved the speed up to the 10 Gbps in the lab scale prototype models.

And this speed can further be enhanced by using the array of LED source or by using the multiple colours of LEDs like RGB LEDs, where each LED source is able to transmit the data up to the 10 Gbps.

Using such technologies, the researchers have achieved the maximum speed up to the 100 Gbps.

If we compare its speed with other wireless communication technologies it is far more advanced.

If we compare it with 4G/LTE or mainly the LET advanced, the maximum achievable speed under this LTE advanced is 1 Gbps for the stationary user and 100 Mbps for the mobile user.

But all these speeds are the theoretically achievable maximum speed. But actual speed may be much lesser compared to this theoretically achievable maximum speed.

So, if you see the countries which provide the fastest internet in the world, the average 4G/LTE speed in such countries is in the range of 40-50 Mbps, which is much lesser compared to the speed which is provided by the Li-Fi.

Now we will compare the speed of Li-Fi with Wi-Fi.

In case of Wi-Fi, if you see the standard IEEE 802.11.ac, the maximum speed which can be supported by this standard is 1.3 Gbps.

And that is in the 5 GHz band, which is almost 100 times lesser compared to the speed which is supported by the Li-Fi.

If you see the another Wi-Fi standard, which is not commercially available yet, that is IEEE 802.11.ad, the maximum speed which can be supported by this standard is 7 Gbps.

And all the speeds which are mentioned over here are the theoretically achievable maximum speeds.

But the actual speeds may be quite lesser compared to the theoretically achievable maximum speeds.

And still, if we consider the maximum speed which is supported by this Wi-Fi technology, the Li-Fi technology is still 10 times faster compared to this Wi-Fi technology.

In current era of Internet, the speed which is provided by the Wi-Fi technology is sufficient for our day to day life.

But as we are moving in the era of Internet of Things, where each device is able to communicate with each other, soon you will find that the speed which is provided by the Wi-Fi technology is insufficient.

And you will require the insane speed like10 to 100 Gbps, which as of now looks like a dream.

If you see the electromagnetic spectrum, the bandwidth of the radio wave is up to 300 GHz.

But if you see the bandwidth of this visible spectrum alone, the bandwidth of this visible spectrum is around 300 THz.

So we can see that the bandwidth of Visible spectrum is 1000 times more compared to the bandwidth of the radio waves.

So, not only you can achieve the higher speed but also you will not find any kind of electromagnetic radio interference.

MORE SECURE

In the case of Li-Fi, as we are using the visible light source, the visible light source cannot cross the walls.

But in case of Wi-Fi, the radio waves are able to transmit across the walls.

Hence Li-Fi technology provides the one more layer of security than the Wi-Fi technology.

This gives it a precision of surrounding security with additional user authentication facility.

INTERFERENCE FREE:

Li-Fi technology is virtual interference free. Like other internet routers for which speed is interfered due to other surrounding effects and disturbance.

But in Li-Fi technology you will get interference free connectivity all the time.

 

These are the advantages of this Li-Fi technology over the other wireless communication technologies. 

 

APPLICATIONS OF Li-Fi TECHNOLOGY:

Let’s have a glance on the different applications of this Li-Fi technology.

(1)    This Li-Fi technology can be used in the hospitals. As this Li-Fi technology is providing very high-speed internet communication, so the real time health monitoring of the patient will be possible.

(2)    Apart from that this Li-Fi technology can be used for the underwater communication systems.

(3)     By using this technology, the vehicles can communicate with each other using the front and the rear lights and LED sensors.

(4)    By using this technology, we can prevent the accidents on Road, Rail, Air and water transpors.

(5)    This can be used in the aeroplanes to provide the internet to the passengers.

(6)    This technology is fitted into our street lights, then even our street lights can provide us high-speed internet.

These are the some of the applications in which this Li-Fi technology can be used.

Apart from all, this Li-Fi technology is the futuristic technology.

That means, the commercially there are no products which are available which provides the insane speed up to the 10 Gbps or 100Gbps.

In the upcoming years, we might see the technologies or devices which support this Li-Fi technology.

At present we are seeing the free Wi-fi Zone in the cafeteria, in future we might see free Li-Fi zone in the cafeteria and markets.

After reading all these points one question might strike in your brain. If Li-Fi is the future of internet then what about the already existing wireless technologies.

The answer is that change is the principle of existence. So definitely this technology will lead and all the existing technologies will diminish by time and use.  

And rather this Li-Fi technology will complement all the existing technologies. Because this Li-Fi is short range communication technology. 

So, for covering large areas we need other technology which can work along with Li-Fi.

Generally we can say, when you require large coverage, we will still prefer Wi-Fi and 4G/LTE but in short coverage, like in the case of our room or hotel or even offices, we can prefer this Li-Fi technology.

I hope in this article, you understood all about this Li-Fi technology thoroughly.

 

Have a great day.

LED Technology – All You Need To Know

Which technology really change our life style? You all have different opinions and different answers. But one thing is common for all of us and  that is LED. So in this article”LED Technology- All you need to know” you will have a thorough knowledge about it. 

LED technology really turns around our life style. Starting from Bulbs to phones, monitors and TVs. Because of it, today we are living in a era of smart bulbs which are consuming less power and energy efficient.

So in this article “LED Technology- All you need to know” we will see that How LED works, types of it, advantages of LED and Usage of it.

LED TECHNOLOGY- All You Need To Know:

If we say Light Emitting Diode than a lay man could not understand what you are saying. But if you say LED than he will understand perfectly.

So, today in many electronic devices we use these LED technology. For example, today these are generally used in smart-phone displays over and above in the camera flashlights. Similarly, today the LED TVs are quite widespread.

And then if we talk about the lighting, then LEDs are used for the lighting in the houses, in the offices and in streets, roads, runways and stadiums. 

Every where we can see the use of LED bulbs and lighting system. Today from the street lights to the traffic signals, or even for the display boards, the LED technology is  commonly used.

Let’s understand the working of it than we will see different types of LEDs than we will see the advantages of the LED technology. 

How LED Works
WORKING OF LED

WORKING OF THE LED TECHNOLOGY

So, now let’s see the working of the LED. As its name suggests, similar to the PN junction diode, it is also one kind of diode.

But whenever the current flows through it in the forward direction, then it emits the light of the particular color.

So, let’s understand the physics behind it.

In PN junction diode, whenever it is forward biased, then the holes on the P side starts moving towards the N side. And similarly, the electrons on the N side start moving towards the P side.

In this way, both holes and electrons contribute in the flow of current.

And during the movement, these charge carriers used to recombine with each other.

In the PN junction diode, whenever these electrons and holes recombine with each other, then they release the energy in the form of heat.

But in case of the Light Emitting Diode, whenever they recombine with each other, then they release the energy in the form of light.

In the crystal structure, the free electrons have more energy than the electrons which are still in the valance orbit.

And we can say that the free electrons are in the conduction band and the holes or the empty space which is left by the free electrons is still in the valance band.

So, whenever the electrons and the hole recombines, then the electrons from the conduction band comes into the valance band. Or in other words, it comes from the higher energy level to the lower energy level.

And as you know, whenever the electron jumps from the higher to the lower energy level, then it releases the energy in some form. 

In the normal PN junction diode, this energy is released in the form of heat.

Because in the fabrication of this PN junction diode, the different semiconductor materials like silicon and Germanium are used.

And in these materials, during the recombination of the holes and the electrons, the energy is released in the form of heat.

On the other end for the Light Emitting Diodes, during these combination or the transition of the electron, the energy is released in the form of light or the photon.

Because in the fabrication of the Light Emitting Diode, different semiconductor compounds, like GaAs and GaP are used. And in this type of Semiconductor compounds, during the recombination, the energy is released in the form of photons.

WAVELENGTH AND BAND GAP

And the energy of the emitted photon is equal to the band gap. That means the energy difference between this conduction and the valance band. Usually, this band gap is represented in the electron Volt (eV).

So, if Eg =hf= hc/lambda ( h= planks constant and f= frequency of electromagnetic radiation) is the band gap, then the energy of the photon can be given as hc/lambda Where h is the Planck’s constant and the C is the speed of light.

And the lambda represents the wavelength of the emitted light. So, as you can see from the equation, the wavelength is inversely proportional to the band gap. Also it is directly proportional to the frequency of electromagnetic radiation.

By band gap engineering, we can change the color of the emitted light.

Direct semi conductor compounds like GaAs (Galium Arsenide), GaP (Gallium Phosphide), GaAsP (Gallium arsenide Phosphide), Sic (Silicon Carbide), GaInN(Gallium Indium Nitride) which are used to generate the different colors of light.

In below table you can find different LED materials for different colors:

LED DATASHEET
ENERGY BAND DIAGRAM

FORWARD VOLTAGE DROP

If we talk about the electrical characteristic of the Light Emitting Diode, then it is very similar to the PN junction diode.

And if you see the V-I characteristic of the diode, then it will be similar to the rectifier diode.

But for the Light Emitting Diode, the forward voltage drop is larger than the PN Junction Diode.

So, for the PN junction diode, we know that the forward voltage drop is in the range of 0.6 to 0.7V. But for the light emitting diode, depending on the emitted color, the forward voltage drop can vary from 1.8 V to 3.5 V.

As we move from IR towards the blue light, then the forward voltage drop of the diode will increase.

So, for any Light Emitting Diode, in the forward bias condition, when the applied input voltage is more than the forward voltage drop, then the Light Emitting Diode will emit the light of the particular color.

But without any kind of series resistor, the current which is flowing through the Light Emitting Diode will be very high.

And due to that, the Light Emitting Diode may get damaged. So, if you see the datasheet of any LED, then there is always mentioned the maximum forward current of the Light Emitting Diode.

And the current which is flowing through the Light Emitting Diode should always be less than this limit.

So, to restrict the current, the series resistor should always be connected with the Light Emitting Diode.

Out of the different specifications of the Light Emitting Diode which you will find in the datasheets. And we have already talked about the first three specifications.

That is LED current, the forward voltage drop of the LED and the wave length.

So, let’s talk about the last two specifications. Now, the brightness or the Luminous Intensity is usually defined for the LED at the specific current.

BRIGHTNESS OR LUMINOUS INTENSITY AND VIEWING ANGLE:

And this brightness is defined in the unit of millicandela.

So, while selecting the Light Emitting Diode for the specific application, one should also consider this specification.

 

Then the other specification which you often find in the datasheet is the viewing angle. So, basically, it defines the directivity of the Light Emitting Diode.

 

And if you see the datasheet of any LED, then you will find this type of polar radiation pattern for the LED.

So, basically, it defines the angle from the maximum intensity where the intensity drops to the 50 percent.

The intensity is maximum at the center and as we move away from the center then the intensity starts dropping in either direction.

And at this point, the intensity drops to 50 percent. So, for this LED, the viewing angle will be equal to roughly 15 degrees.

If we consider the full angle then it will be equal to 30 degrees.

But in the datasheet usually it, is specified as the half angle.

 

This is all about the different specifications of the LED. Now let’s briefly talk about the different types of LEDs. 

LED Viewing Angle

SMD & COB LED
SMD AND COB LED

DIFFERENT TYPES OF LED:

HOLE LED

So, the first type of LED is the through hole type of LED. And still, it is very popular among the electronic hobbyist.And still, it is used in the many applications.

SMD LED

Then the second type of LED is the SMD LED. It is also known as the Surface Mount LEDs. This type of LEDs is very tiny in the size and they are mounted or installed on the circuit board itself. And today they are quite commonly used in the LED bulbs and the other applications.

HIGH POWER LED

Then if we talk in terms of power, then there are high power LEDs. So, these LEDs can handle a much more current than the normal LEDs. And therefore they are much brighter than the normal LEDs.But because of the large power dissipation, they are always used with the heat sinks.

COB LED

Then the other type of LED is the COB LED. And it is known as the Chip On Board LED. So, it is very similar to the SMD LED. But here so many tiny LEDs are installed on the same chip. And hence it is much brighter than the other types of LEDs.

 

RGB LED

Then the other type of LED which is commonly used today is the RGB LED. So, if you look at the through hole type of RGB LED then it contains the four leads.

So, if it is a common cathode type of LED, then it has a common cathode and the three anodes for the different colors. That means three anodes for the RED, GREEN and the BLUE LED.

And by changing the current through each LED, we can get the different shades of color. This type of RGB LED is also available in the SMD packages. And these types of LEDs are quite commonly used for the decoration purpose.

 

ALPHANUMERIC LED

At the last let’s talk about the alpha numeric LEDs. So, these type of LEDs are used to display the numbers and the alphabet in the various industries.

 

So, these are the different types of LEDs which are quite commonly used in today’s world. 

THE ADVANTAGES OF THE LED

Now, whenever the LED bulbs are used for the lighting, then they are more energy
efficient than the conventional bulbs.

Also, the lifespan of these LED bulbs is more than conventional bulbs.

Then the third advantage of the LED is that it can be operated in the fast switching
application.

And the other advantages are the smaller size and the better controllability. Now, here controllability is in the sense that the brightness of the LED can be
easily controlled.

 

These are some of the advantages of it. 

USGAE OF LED TECHNOLOGY:

Different usage of LEDs in really:

Ø   Television technology

Ø    SmartphoneTechnology

BITCOIN-EVERYTHING YOU WANT TO KNOW 

Today we are living in a digital world. So, digital currencies are pretty much common in use. This article ‘Bitcoin- Everything you want to know ‘ will give you a complete knowledge about it.

WHAT IS A BITCOIN

Bitcoin is a type of Crypto Currency which is virtual in nature and is independent from traditional banking system and came into circulation in 2009.

Top experts and traders predict that, Bitcoin is considered as the best known digital currency. 

It relies on computer networks to resolve complex mathematical problems, in order to confirm and record the particulars of each and every transaction.

Its exchange rate does not depend on the central banks regulations and there is no single authority that governs the supply and management of Bitcoin.

The value of Bitcoin depends on the users confidence and its demand all over the world.

HISTORY OF BITCOIN

Its creator was a nameless group of bright mathematicians (using the fabricated name Satoshi Nakamoto) who designed and developed it in 2008 to be “virtual gold”.

The first Bitcoin software released in early 2009 during the USA economic crisis.

They knew that to have lasting value, like gold it had to have a finite supply and so they give capping on production of Bitcoin.

So during creation they capped the supply at 21 million Bitcoins.

On 31 October 2008, a paper titled Bitcoin: A Peer-to-Peer Electronic Cash System was posted by the author name Satoshi Nakamoto. 

Satoshi Nakamoto implemented the bitcoin software and released it in January 2009 for use by others.

On 3 January 2009, the bitcoin system was created when Satoshi Nakamoto mined the first block chain of bitcoin, known as the genesis block

UNIT OF MEASUREMENT 

The unit of account of the bitcoin system is a bitcoin. 

Symbols generally used for expression of bitcoin are BTC and XBT.

Millibitcoin (mBTC), and Satoshi (sat) are the two small amounts of bitcoin used as alternative units.

A satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoins, that is equal to one hundred millionth of a bitcoin. 

A milli-bitcoin equals to 0.001 bitcoin.

One thousandth of a bitcoin or 100,000 Satoshi.

CURRENT STATUS OF BITCOIN

In 2014, We expect exponential growth in the popularity of it around the world with both merchants and consumers using this virtual coin.

India has already been cited as the next likely popular market that Bitcoin could move into.

It’s growth in 2014 on wards is due to various Bitcoin ATM’s, mobile apps, new technologies and tools implemented in this field.

Recent Bitcoin price collapse due to Covid-19 case:

According to Coin Metrics and Forbes, on 11 March 281,000 bitcoins were sold by owners who held them for only thirty days or more.

This compared around 4000 bitcoins that had laid inactive for a year or more indicating that the vast majority of the bitcoin volatility on that day was from recent buyers.

During the second week of March 2020 as a result of the COVID-19 pandemic Crypto currency exchange Kraken experienced an 80% increase in the amount of account signups over the week of bitcoin’s price collapse.

This was due to after effects of  buyers looking to capitalize on the low price.

It’s exchange rate with USD is a strictly watched.

Benchmark of it is carried out on a daily basis and long term over the last 8 years since its introduction to the world’s financial marketplace.

A popular company to receive the most current rate in Bitcoin valuation is XE.

They show Bitcoin to USD valuation and also the complete its price chart.The Bitcoin value chart and the Bitcoin to USD chart.

If you ask, “How much is one Bitcoin?” you will always know from their continuously updated charts.

In INDIA 01 bitcoin is equals to Rupees 687447.43  approximately.

As of 2020, about 18 Million of it in subsistence and were in market. However, you can not use all of them.

Out of the mined Bitcoins of 18 million, roughly 4 million are lost. 

Another 1 million were stolen in various hacks and heists such as that of through Mt. Gox.

Now we are having only 13 million of it for use by remaining people. Also “Whales”! (Whales are people who own a huge number of bitcoins)  stashed away a huge number of Bitcoins in their wallets.

Among these whales is the founder of it, Satoshi Nakomoto, who might have about 1 million bitcoins which are roughly worth 10 billion US dollars at present cost.

HOW TO INVEST IN BITCOIN

A question that frequently comes in our mind that “How to buy its stock”. By far the most common way to proceed in this area is to buy it directly and not its stock.

There is one entity called Bitcoin Investment trust which is an investment fund that is designed to track the market flow of it. 

Some analysts however are calling this a risky way to become involved in this marketplace.

It’s predictable value is a subject frequently discussed by various investment giants.

In January of 2015 the price of one bitcoin was $215. Currently it is around $8000. 

This is an exceptional increase and one far beyond what most experts would have projected at that time.

Currently different reviews are there regarding its value.

In reviewing forecasts from experts all over the world, a common answer seems to be that the top value will settle in at around $10,000. 

Some experts also have an opinion that its projected a value reaching $100,000 in future.

WALLETS:

One must know what a Bitcoin wallet is and how to use it.

A Bitcoin wallet is defined as something that “stores the digital credentials for your bitcoin holdings” and allows its owners to access and spend them online. 

It is simply the Bitcoin account comparable to a bank account.

It allows you to get Bitcoins, stock up them and drive them to others. What it does is store a compilation of Bitcoin privacy keys.

Usually it is encrypted with a password or otherwise protected from unauthorized access.

There are several modes on which wallets can operate and drive. 

There are two types of relationship with regards to trust and computational requirements.

FULL CLIENTS:

  • Full clients verify transactions directly by downloading a full copy of the block chain (A full copy of block chains is over 150 GB as of January 2018). 
  • It is the safest and reliable way of using the network, as trust in external parties is not required.
  • They regularly check the validity of mined blocks, and preventing them from transacting on a chain that breaks or alters network rules suggested for it.
  • Because of its size and complexity, downloading and verifying the entire block chain is not suitable for all computing devices and high end GPU’s and servers are required for this.

LIGHTWEIGHT CLIENTS:

  • Lightweight clients consult full clients to send and receive transactions without requiring a local copy of the entire block chain also known as SPV (Simplified payment verification).
  • These accounts are quicker to set up and allows them to be used on very less power, less bandwidth devices such as smart mobiles and normal PC.
  • When using a lightweight wallet, however, the user must trust the server and online wallet providers.
  • They follow the longest block chain and do not have to ensure its validity.
  • They also have to trust the miners.

There are several types of digital wallets to choose from.

Web wallet:  

This type of wallet allows you to send, receive and store Bitcoin though your web browser.

Desktop wallet:

In this type of wallet, generally wallet software is stored directly on your computer/PC /Laptop desktop.

Mobile Wallets:

This type of wallets are designed to use in Mobile devices by users.

 

HOW TO GENERATE INCOME FROM BITCOIN

Unlike other currencies, there are three ways to make money with it.

Saving, trading and mining are the three ways of generating income from it.

SAVING:

In savings income generation through Bitcoins, you have to purchase some bitcoins and save it for some time.

After that when its value increases you can make profit and generate income from that.

TRADING:

It can be traded on open markets, which means you can buy Bitcoin in low value and sell them in high value. With this you can make a profit from it’s trading.

MINING :

Mining is a very time, money and power consuming process. 

Mining is a type of record keeping service done all the way through the use of high end computers and servers.

Miners keep the block chain steady, complete, and unalterable by repeatedly grouping newly broadcast transactions into a block.

After that it broadcasts to the network and verified by recipient nodes.

After that each block contains cryptographic hash of the previous block, thus connecting it to the previous block and the block chain is named after that.

To be acknowledged by the rest of the network, a new block must contain a proof-of-work (PoW).

The system generally used in this process is based on Adam Back’s 1997 anti-spam scheme known as Hash cash.

The PoW requires miners to find a number called a nonce.

When the block content is hashed along with the nonce, the result is numerically smaller than the network’s difficulty target.

This proof is easy for any node in the network to verify, but extremely time-consuming to generate.

As for a secure cryptographic hash, miners must try many different nonce values.

About 2,000 blocks takes approximately 14 days approximately. And roughly it takes around 10 min per block to verify.

The difficulty target is adjusted based on the network’s recent performance, with the aim of keeping the average time between new blocks at ten minutes.

Between March 2014 and March 2015, the regular number of nonce’s miners had to try before creating a new block increased from 16 quintillion to 200 quintillion.

The proof-of-work system, alongside the chaining of blocks, makes modifications of the block chain extremely difficult and time consuming.

An attacker has to modify all subsequent blocks in order to modify one block to be accepted.

As new blocks are mined all the time, the difficulty of modifying a block increases day by day. As time passes and the number of subsequent nonce’s increase it is getting more and more difficult.

FRAUDS IN BITCOIN

As It is valuable and digital in nature. It attracts different scams and frauds.

 

RECENT TWITTER BITCOIN SCAM

On July 15 this year (2020), a number of high-profile Twitter accounts, each with millions of followers, were compromised in a cyber attack to encourage scam on bitcoin.

The scam asked account holders to send bitcoin currency to a specific Crypto currency wallet, with a promise that money sent to it will be doubled and returned.

The perpetrators had gained right of entry to Twitter’s administrative tools so that they could modify the accounts themselves and post the tweets straight to the users.

The path is not sure but they are supposed to have gained access either through paying off Twitter employees a ambit amount of money to use the tool. 

Also they might have used a compromised employee’s account to access the tool directly.

More than 12 bitcoins were sent to one of the addresses involved, the equivalent of more than US$110,000. 

Minutes after the tweets were posted, more than 320 transactions had already taken place on one of the wallet addresses.

 

EARLIER FRAUDS IN INDIA:

A tech guy named Amit Bhardwaj arrested by Delhi police at Delhi airport when he was trying to escape out of country after a Rs 2000 crore fraud in Bitcoin.

About 8000 peoples were fallen into his trap of opening Bitcoin accounts and wallets.

This happens due to no regulatory authority of Bitcoin.

Many frauds and scams you can notice in Bitcoin transactions. So be careful at the time of Bitcoin investment.

ADVANTAGES AND DISADVANTAGES:

ADVANTAGES OF IT:

LOW INFLATION RISK:

One of the benefits of Bitcoin is its low inflation risk.

Traditional currencies undergo inflation and deflation around the year or decade. They have a tendency to lose their purchasing power each year.

As governments continue stimulate the economy by injecting stimulus packages from reserve money.

Bitcoin doesn’t suffer from low inflation, because Bitcoin mining is restricted to just 21 million units.

That means the release of new Bitcoins is slowing down and the full amount will be mined out within the next couple of decades.

Experts have predicted that the last Bitcoin will be mined by 2050.

LOW RISK OF COLLAPSE:

Bitcoin has a low risk of collapse dissimilar traditional currencies that rely on governments and central banks.

When currencies collapse, it leads to hyperinflation. In hyper inflation you will have to give a lot of money to buy one small thing.

During hyper inflation your whole savings account can be wipeout in an instant.

Bitcoin on the other hand have low risk of collapse as its exchange rate is not regulated by any government plus is a digital currency available worldwide.

EASY TO CARRY:

Bitcoin is easy to carry and easy to transfer.

A billion dollars in the Bitcoin can be stored on a pendrive and placed in one’s pocket. It is also very easy to transport Bitcoins as compared to regular paper money.

DISADVANTAGE OF IT:

UNTRACEABILITY:

One disadvantage of Bitcoin is its untraceability nature.

As Governments and other organisations cannot trace the source of your funds.

So that it  can attract some deceitful individuals and online hacking your money transactions might happen.

THE FUTURE OF BITCOIN

Bitcoin mechanism works, but critics have believed that the digital currency is not ready to be used by the mainstream because of its volatility.

They also point to the hacking of the Bitcoin exchange in the past that has resulted in the loss of several millions of dollars.

Supporters of digital currencies have said that there are newer exchanges that are supervised by financial experts and venture capitalists.

Experts further added that there is still anticipate for the virtual currency system and the predicted growth is gigantic.

When the major companies will accept Bitcoin as a method of payment, the more successful Bitcoin will become in future.

CONCLUSION:

So this is all about Bitcoins and How you can invest and make money from it.

Definitely this article ‘Bitcoin-Everything you want to know ” increase your knowledge on it and Crypto currency.

You like it or not this is part of our digital virtual currency today and will remain with us in future.

  • Good writing skill:

To become a professional blogger you need to be a good writer and that to you have to love writing. Because to becoming famous in Blogging carrier you have to be patience. Also you need to be a content writer. You have to choose a content and write on that topic.

  • Good knowledge on a language:

Like a good writer you must be very proficient in the language you are writing. If you are good in English than start your blog in English and if you are good in Hindi than start your blog in Hindi.

Now that you know the basic things required for blogging. So move further in this article:

How to start a blog?

  1. Reasons for blogging:

You need to choose what you are blogging for. You are doing it for fun or for making money.

If you want visitors in your blog, what do you want them to do when they arrive and spend quality time inside your blog. If you just like to write, than it is fine, blogging can be absolutely curative in some ways.

  1. Niche- Fix on a topic:

If you are very sure about the motive that you are blogging then that will help you value and decide on what you are going to blog about.

Deciding your Niche is a crucial part of your blogging. So think it carefully and research properly before deciding your Niche.

What you are going to blog about is also dogged by the people that you are soothing to talk to.

You can blog about the topic you are mastered, on current news, on viral videos, on latest products and gadgets or controversial topics.

You can write down certain topics, of regular and related to your life style like Yoga, Gym, Health and Food.

By staying stable on one topic you can gain credibility and be seen as an expert in your field.

So if you have decided your Niche than start blogging.

You can go for making a Free blog site or a paid blog site.

  1. Free blog Site:

Free blogs are everywhere in the web.  In free blog you will be provided with free domain and free Hosting.

In free domain your decided domain name or Niche will come along with the platform name. e.g XYZ@blogger.com.

You just simply do a web search and you can hit upon some free good free blog providers. Some examples are blogger.com, WordPress.com, blog.com and Weebly.com. But in free blog sites you will not get the freedom you wanted you cannot change the theme you like or many more constraints are there.

Your blog will not be your own but; the domain will be something like deepaksblog.wordpress.com so you will have the same domain name as many other people have.

If you are trying to make money most of the free services don’t allow you to advertise on their sites and they will restrict you.

Free blogging services aren’t the finest options I will suggest you if you want to make it professional. It is just an easy and free way to start learning swimming in swimming pool before going to swim in river.

  1. Paid blog sites:

If you have decided to go for paid blogging site of your own than again two things you will need to start.

Purchase a DOMAIN name of your choice:

Now you will have to register and record a domain name (this is the actual name of your website/blog). Price range may defer as per the SEO difficulty and easiness.  It may be started from about 100 rupees and can go up to thousands.

You can use a service of Go-Daddy, Site-ground, Hostinger or Host gator to register you domain name.

The trendier domain names usually cost more. A nice simple option when opening is to go for names like firstnamelastname.com etc something like that.

You can always change the domain name later or have more than one all linking to the same actual webpage.

After purchasing domain you need a Host to start your website.

HOSTING:

For a paid blog you have to pay for the domain name and the hosting services.

Buying a hosting service is like buying a plot to construct a house. After buying hosting you are ready to construct  your blog site in internet.

You will then own the blog yourself and therefore have more control over the blog when you begin to try and make money.

A lot of the free blogs don’t allow you to advertise on it but you can start advertising and earn money in your paid blog sites.

You can get Hosting options through  HostGator.com, GoDaddy.com, Siteground.com all offer hosting solutions.  Some are cheap and some are costly.

At the time of buying you should see the performance of the site and match its up time with other service providers.

Most of these hosting provides will provide you with instructions on how to use of Word Press on your new hosted domain.

If you know HTML, Java and CSS you can beautifully design your website through codes.

  1. Traffic

When you publish something on your blog you want people to read it or watch it. This is where traffic comes in. If you want your blog to be successful you need to learn to get traffic to it.

There are many different options here depending on your expertise and budget. Basically traffic can be broken down into free and paid traffic.

Free traffic includes the following:

  • Search engine traffic of google, yahoo etc.
  • Social media traffic (Facebook, twitter, instagram etc)
  • Article marketing through different article posting sites.

All of these topics by themselves could be the topics of pages you want to write.

Paid traffic includes the following:

  • PPC (paid per click): advertising, eg the little ads you see at the top of every Google and yahoo search engines
  • Solo ads: which is where you pay someone with a large list of email subscribers to email them and tell them about your blog,
  • Banner advertising: you buy an advertisement space on a website for a set of term and advertise your site.

  1. Contents:

Once you have your site up and running you need to create posting relevant content in the form of articles, pictures or videos.

For ideas on what to write about check out current trending videos at YouTube.com, news providers like CNN.com, BBC, ZEE News, or simply Google search news.

So I hope this article “How to start a Blog” has given you a basic idea on starting a personal and professional Blog.

Power Bank- A Complete Guide To How To Choose

0
How to choose a power bank

I am pretty much frustrated when my smart phone batteries got empty. The same thing might happen with you all. Well there are two things you can do. First you will charge a smart phone or grab the power bank. Keeping in view i write this article “How to choose a power bank”.

But buying a good power bank is harder than you might think. Because of false advertising and paid review it is slightly confusing. So I am going to describe you some truth about power banks.

Smart phones have become our daily life companion and we need more and more battery life. Mostly a full charge is not enough for a day if you are a robust user. That’s why we should know how to choose a power bank.

The easiest way to expand your battery life is a power bank. But which one should you buy if you check out power banks on Amazon then you can find a lot of mixed reviews many reviews are paid.

In general, most people just search for the biggest capacity advertised for a low price. But this is something you should not do and the reason is that sellers mostly lie about the capacity.  

First let me explain how a power bank works and why you can’t simply divide your power banks capacity by a sound battery capacity and get the charging cycles.

 

HOW TO CHOOSE A BATTERY BANK:

Selecting a battery bank is not a small job but it is quite mind storming. Following topics will help you to know “How to choose a  good battery bank”.

TECHNOLOGY OF BATTERY BANKS:

So there are different kinds of power banks with different battery technologies.

Mainly two types of technologies are used in making battery banks. One is Lithium-ion technology and the other one is lithium polymer technology.

SIZE:

On the inside, cheaper power banks use lithium-ion cells especially the affordable 18650 cells. These cells are classified by its 18mmX 65mm size. They are cheaper and they are of size little bit larger than Lithium polymer batteries.

But well that’s the only advantage they have. A higher discharge rate just to get hotter and are not really durable compared to the new lithium polymer cells.

However Lithium polymer power banks are more expensive and also harder to get. But they are smaller and more durable on the long run.

FIRE CATHING/ EXPLODE:

Also the Lithium ion batteries can catch fire more easily because of their fluid electrolyte.

On the other hand Lithium polymer batteries use a solid or gel electrolyte and more safe.

CAPACITY:

Now let’s talk about the actual capacity. Because it gets tricky power banks get to 90% produced in China and most cheap unknown manufacturers of original manufacturer’s data tricky about the battery capacity.

So that’s a fact but although the capacity advertised is not the actual capacity that goes into your battery bank.

So first the capacity inside is measured as mAh that stands for milliamp hours and tells you how many milliamps or amps you can drain from the battery in one hour.

So for instance a 10,000 milliamp hour battery means you could drain 10,000 milliamp to one hour or for instance 1,000 milliamps for ten hours draining capacity.

But you can only do this at the rated voltage of the cells and most cells are rated at 3.7 volts. If you multiply a million amps and the rated voltage you get the actual energy.

 Which would be three point seven watt hours that means you can drain three points seven watts for one hour from the battery. But why do we need to know all that.

So you need to know that USB ports are made to operate at five volts. So you always plug a smart phone into five volt source. This is the output of the normal USB port of your notebook or phone charger.

So inside of the power bank the voltage has to be stepped up from the three point seven volts to five volts using a boost converter.

This conversion is not loss less that means there is a conversion loss to calculate. The root capacity takes the advertised power bank capacity times three point seven and divided by five this is how your real capacity calculated. And it’s always lower than the advertised capacity of the power bank.

The second factor is the efficiency factor.

And this one depends on your power bank. Cheaper power banks have a bad converter inside that transforms a lot of energy into heat which is lost by power bank. In high quality power banks have better up stepper resulting in a small loss.

So good power banks lose minimal and give you more power than worst quality power banks.

Let’s say 20% in some and 30% or way more in some power banks.

 Now let’s do the math. Your 10,000 mAh power bank at frequent cell walls actually can only supply seven thousand four hundred million AMPS at five volts.

And if the converters crap then maybe even less and maybe in a couple of months even more less because it sounds alter gradually with time.

So if you thought that you could charge your 2000mAh and you do not found five times with10,000 NH battery then you will disappointed because it just has 5900 mAh coming from with power banks.

Use B port and there is another conversion in your smart phone back to 3.7 volts. So this advertised 10,000 mAh power bank will charge a smart phone only around 2.5 times.

Also 10,000 mAh capacity power banks are common in use than other power banks. Because it is very handy and easy to carry.

PORTS:

Generally power banks come with 2 charging USB ports.

One is 1 A and other is 2.1A.

5V/1A port is used for smart phones because it needs around 1A current for charging.

5V/2.1A port is used for tablets because it needs some high current to be charged.

Today you can find 04 port or 05 port power banks with high capacity devices which enhances the charging capabilities of 4 or 5 devices simultaneously.

FAST CHARGING:

Now a day’s fast charging is one of the main features of battery bank. This specification is very useful in our day to day work and travelling. You can charge your smart phones with 18W fast charging speed.

In reverse how fast your battery bank recharges itself is also important. So check specifications more accurately with these features.

CASING:

Outer Casing is also much important as inside features. Outside casing should be attractive and durable. Normal Plastic casing can brake easily and catch fire. So go for hard plastic casing or silicon fiber casing.

External casings also available in market for extra cover and precaution to your power bank. You can purchase it and use it if you casing is not so durable.

 

PRECAUTION DURING POWER BANK USE:

·       Don’t use your smart phone or other devices while it is in charging condition. Because by doing this you are making the battery in line with the phone and it causes higher power draw and excessive heating of your device and power bank. If it is made up of Lithium ion technology then you should be more careful. Because it can explode and catch up fire. It may harm you or make a big fire incident.

·       For health benefits also you should not use your smart phone while it is charging. Because during charging if you will use your phone than battery chemicals may leak and harm you.

·       Battery may bulge in size and you can notice the swelling of your phone and power bank.

·       Charging capacity of your smart phone and power bank may decrease gradually and prone to unserviceable in frequent use.

·       You can get an electric shock during charging.

·       Radiation from your smart phone increases during charging. It will affect your health and may cause cancer.

CONCLUSION:

So be careful during usage of power bank and choose wisely during purchasing of such devices from market. Stay healthy and enjoy your life.

Have a good day.
