What's inside a computer?
THE CPU FAN
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 overheatSteve 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 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 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)
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.
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
