What is connectionless?

Connectionless means sending a message without checking if the person is ready to receive it, like throwing a ball across the room and not waiting for the other person to catch it before you throw another one.

Imagine you're playing tag with your friend. Instead of running back to check if they caught the ball, you just keep throwing more balls, one after another, without stopping. That's connectionless communication!

Think of it like leaving notes on a table for your friend during lunch. You don’t wait for them to read the first note before you leave the second one. Sometimes they might miss a few messages, but that doesn't stop you from sending more.

This way of communicating is fast and simple, just like how some computers talk to each other without waiting for a reply every time!
