What is it?

A video call is like a regular phone call, but you can also see the person you are talking to on your screen. It uses the internet to send both your voice and your video to the other person, letting you chat face-to-face even when you are far apart.

Simple Example

Quick Example

Imagine your cousin lives in another city, like Bengaluru, and you are in Delhi. Instead of just talking on the phone, you can make a video call to them. You will see their face on your mobile phone or computer screen, and they will see yours, just like you're sitting together having chai.
