What are networks of computers?

A network of computers is like a group of friends who can share toys and messages with each other from different rooms in a house.

Imagine you have a toy phone that lets you talk to your friend in the next room. Now, imagine your friend has another toy phone, and both of you can also send notes through a little tunnel under the floor. That’s like how computers work when they're part of a network, they can chat, share pictures, or even play games together, even if they’re not in the same room.

Just like your toy phone uses wires or radio waves to send messages, computers use special lines called cables or invisible signals through the air. These connections are like invisible strings that let computers talk to each other, and even share their favorite songs or games!

When you're playing a video game with your friend on another computer, you’re both using a network of computers. It’s like having a big party where everyone can join in from anywhere, just by using the right tools!
