To understand why Operating systems not only exist today but why they take the forms they do, one has to have an understanding of the development of computers. The first computers were only designed to do a specific task and weren't for general computing. Later on, when the programmable general purpose computers were invented, it became easier to operate a computer, but these computers still could only run one program before the computer needed to be restarted.

Soon it was found that it was very useful to not only have a computer that looped indefinitely to monitor certain activities, it was useful to run multiple programs at once. It was decided that a mediator was needed to run all these tasks to make sure everything ran smoothly and so the operating system was born.
