What are switches?

A switch is like a light toggle you flip to turn on or off, but instead of lights, it controls computers and devices in a network.

Imagine you're playing with your toys. You have two toy cars. If you want them to talk to each other (like sharing a secret), you need a bridge, and that’s what a switch does. It connects all the devices, like toy cars, phones, or computers, so they can chat without getting confused.

Think of a switch as a traffic cop for data. When one device wants to send information to another, the switch checks where it needs to go and sends the message straight there. It doesn’t broadcast it to everyone like a shout, it’s more like a whisper to just the right person.

Without switches, all devices would have to talk to each other at the same time, which gets messy and slow. A switch keeps things organized so messages go where they need to go quickly and clearly, just like how you know exactly where your backpack is in your room.
