How does a computer works
 It takes in raw information (or data) at one end, stores it until it's ready to work on
it, chews and crunches it for a bit, then spits out the results at the other end. All
these processes have a name. Taking in information is called input, storing
information is better known as memory (or storage), chewing information is also
known as processing, and spitting out results is called output.
