Multiplexer

Okay, so you know how you have different toys and you only play with one at a time, right? A multiplexer is kinda like that, but for computers!

Think of it like a toy box with different compartments. Instead of toys, it has lots of wires (think of them like strings that help computers talk to each other). The multiplexer helps the computer pick which wire to use at a certain time.

So let's say the computer wants to send a message to another computer. It needs to pick a wire to send it on. But sometimes there are too many wires to choose from, and the computer gets confused. That's when the multiplexer comes in – it helps the computer pick the right wire to use.

A multiplexer can choose between lots of wires by using a special code. It's like a secret language that tells the multiplexer which wire to use. Then, the multiplexer sends the message on that wire.

So a multiplexer is a bit like a toy box with lots of compartments – it helps the computer pick which wire to use, so that everything works smoothly and nothing gets confused!
