Definition
What is it?
A video call is like talking on the phone, 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 picture to the other person, and vice-versa, in real-time.
Simple Example
Quick Example
Imagine your cousin lives in another city, far away. Instead of just hearing their voice on a regular call, a video call lets you see their face, their expressions, and even what they are doing while you chat. It's like they are right there with you, even if they are miles away, maybe even enjoying a cup of chai.

Common Mistakes
MISTAKE: Thinking video calls only need a phone number. | CORRECTION: Video calls need both a phone number (or contact ID) AND an active internet connection (Wi-Fi or mobile data) to work.
MISTAKE: Not checking if the other person has the same video calling app. | CORRECTION: Both people on a video call usually need to use the same app (e.g., both use WhatsApp, or both use Google Meet) for the call to connect.
MISTAKE: Forgetting to turn on the camera or microphone. | CORRECTION: Sometimes, you might accidentally turn off your camera or microphone during a call. Always check the on-screen icons to make sure they are enabled if the other person can't see or hear you.
