  • The operating system basically provides a way for the user to interact with the hardware as well as for other programs to use hardware to interact with the user or other programs. Most programs require an operating system because they rely on the operating system interpreting their commands and then sending instructions to the hardware. However, you don't need an operating system. Some programs can be run without one (most assembly programs could be adapted to run without an operating system). The two most important reasons for an operating system to exist are: to allow the user to perform file system tasks and calibrate hardware, and to make programming easier.
  • So that you can use it easily. Without an operating system you'd have to do everything from scratch yourself, which would be a bit of a pain!
  • probably to operate a computer
