The computer fan and RAM
Two key components for your computer!
The Computer fan:
The computer fan is responsible for keeping your computer cool. It draws warm air out of your computer and replaces it with cool air. It is very important, even more that the RAM or CPU as both of those components would be useless if they were burnt! Fans aren't just for these components, many people have fans made specifically for different components like the hard drive, graphics card and mother board.
The RAM (short for random access memory) is used to "access" any piece of information whenever you want. It's called the random access memory because you can access any piece of information it has, regardless of what it is. The opposite of this is a SAM (serial access memory) an example of this is a cassette tape.
