ELI5: How does computer storage work, and how do files "take up space"?

Computer storage consists of millions of switches. Each switch can either be on (which represents a 1) or off (to represent a 0).

The space a file takes up is basically (but a little over-simplified) the number of switches it takes to represent the information in the file.
