A switch in networking is like a mailman who delivers letters to different houses.
Imagine you have a bunch of devices (like computers, phones, and tablets) in your house, and you want them to talk to each other and share things like pictures and videos. But, just like how a mailman can’t deliver letters to multiple houses at the same time, your devices can’t talk to each other directly all at once.
That’s where a switch comes in! A switch is like a helper that takes all the messages from your devices and sends them to the right device that the message is meant for. It looks at the address of the message (like a house address) and sends it to the right device, so they can all talk to each other easily.
So, a switch is like a helper that makes sure all your devices can talk to each other without getting confused!
