Representing and Storing Data


How Information is Stored?

There are really just four basic types of information that we need to store on a computer:

  • numbers

  • text (i.e. alphanumeric characters)

  • images

  • sound

There are other types, such as video, but there are combinations of the four types listed above – e.g. a sequence of images together with some sound.

In this unit you are going to learn how the computer using only 0s and 1s can represent all this information.
