Think of a computer as a brain, that has no arms, legs or eyes. For this computer to be able to interact with us we need to connect some things to it. For the computer to be able to show us what’s going on, it needs to have a screen plugged in, to allow us to interact with the computer we need to plug in a keyboard and mouse, and for the computer to be able to share any noise it’s making it need to have speakers plugged in.
Luckily everything that we need to plug into a computer has a cable with an end that’s specifically made to be plugged into a computer. By learning to distinguish the ports on your computer you’ll be able to tell what you’re able to plug into you’re computer before you buy it, and setting up your computer will be an absolute breeze.
