Currently, we can see most people owning a smartphone doing something on it. What exactly? Social media? Videos? Audios? Chat? Photo? Games? Every day, some company launches a new feature on their phones. Thousands of apps are being published every day on Google Play and Apple Store. Let’s understand that what is happening.

A computer require two things to operate, one is hardware i.e. smartphone, laptops, etc. and other is software i.e. apps, chrome, mircosoft office, etc. The computer is very powerful device and it can change the World then why is it not changing your life? Because, you don’t have proper training to use, what to use, how to use and why to use a particular apps/software.

Here’s a short WhatsApp Training –

WhatsApp is a communication app can be used using a smartphone or computer to communicate with friends, family and business contacts and share information to each other using text, images, audios or videos.

Now let’s talk about communication. What is communication?

Wikipedia says, “Communication is the imparting or exchanging of information by speaking, writing, or using some other medium.”

When we send a message to the group or someone privately, we need a medium or channel and here we have WhatsApp. While communicating, we take care of who will read the message, someone private or a group. Now a question comes to our mind, can anyone or computer can read this message other than receiver? The question is very genuine because we don’t want the third party to read our message.

Now, encryption comes into the picture. WhatsApp says, “We’re simple, secure and reliable messaging”. What does it mean? Let’s see –

Simple: Anyone, who can have a smartphone or computer with the internet connection can use this application whether s/he is the tribal person or a highly educated person. How?

Simplest for of communication on WhatsApp step-by-step:

1. Unlock phone
   
2. Touch on WhatsApp icon to open.
3. Identify contact with profile picture/icon.
4. Touch and stay on the microphone icon.
5. Record your message.
6. Leave the microphone icon. 
7. Your message sent.

This is the easiest thing what anyone in the World with no prior experience with technology can start communicating with friends and family. This is how simple it is.

Secure: One of our most personal moments are shared on WhatsApp, which is why they built end-to-end encryption into the latest versions of the app. When end-to-end encrypted, our messages and calls are secured so only you and the person you’re communicating with can read or listen to them, and nobody in between, not even WhatsApp.

What is encryption?

In a nutshell, when we send a message to someone then it can be read by anyone but can understand by the receiver only. Let’s simplify this, when we type a message and we send it, it’s being encrypted before sending and decrypt on the receiver phone. If anyone or the computer will try to read the message then they’ll get only gibberish.

E.g. Sender Original Message: I LOVE YOU
Sender Encrypted Message: B KSDF QSI
Decrypted Message on Receiver Phone: I LOVE YOU
Anyone other than sender and receiver, they’ll see only B KSDF QSI rather I LOVE YOU. This is how WhatsApp is secure.

Reliable Messaging: With WhatsApp on the web and desktop, we can seamlessly sync all of our chats to our computer so that we can chat on whatever device is most convenient for us. It’s a medium which rarely fails to deliver our message or the server is down.

This is how the WhatsApp is reliable.

Conclusion: We learned, WhatsApp is a communication app which is very powerful and secure to send or receive a message. We should use WhatsApp as a medium or channel to communicate purposely. Misusing of WhatsApp will lead to any legal action or waste of time.
