What's inside a computer?


This Stands for Central Processing Unit, and tells the computer what to do.

It accesses the different parts of the computer and then gets them to work together, like your brain. Without it the computer wouldn't work


This is the cooling system of the computer.

It makes all the warmth exit the computer.

If the fan will stop working, the computer will stop working along with it, as it will overheat

Steve jobs made the mistake of not taking the fan inside his Macintosh so that the computer will be quieter. This caused the New computer to not sell well.

Northbridge and Southbridge

The Northbridge is the communication to the CPU (see above), RAM (see below), PCI-E (ditto), and southbridge.

The Soutbridge is the other communication center, and connects to the Input and output (audio jack, USB drive etc. (all below)) It then send the information to the northbridge, which sends it to the CPU

The VGA and VGA Port

The VGA (Video Graphics Array) is a cable that is used for games and computer TVs and stuff that need graphics the computer can't find with a simple code

The VGA port is where you plug in the (guess what?) VGA cable. Most Desktops have it and some laptops have a smaller version, which needs an adapter to fit in a proper VGA (a bit like a SD and mini-SD cards)


the Really annoying memory is not a RAM (although it will be annoying to try remember it's full name. RAM stands for Random access memory and is the quick path to memory.

A good RAM will have a space of about 5 GB, but you will need more if you are going to do stuff like photography or music, or your Monitor will freeze once in a while.

You might already have guessed that the RAM is where the background and foreground keep the information.


USB stands for Universal Serial Bus

This is a mini-drive with a usual space of 4 GB.

More is good, but it will cost extra money, and a Gigabyte is more space than you think

A usual computer has 2 USB drives, and sometimes 3

A USB drive takes up no extra space in your computer, and can fit in your pocket. The important think to remember is just that touch-screens don't usually support USB, so another cable will be needed for that

The Audio Jack

This is where you plug in your ear and headphones and where you connect to a speaker

It transfers all the sound the computer makes to another device

That's pretty much all it does
