System Software

A computer is controlled by systems software. Operating systems provide this control, while utilities help to maintain the system. Note: this is different from "applications software" like word processing software (e.g Microsoft Word)

Systems software is software that governs the computer system. It:

  • -controls the hardware, including any peripherals
  • -allows other programs (applications) to run
  • -provides an interface for the user to interact with the computer
  • -maintains the system

There are two kinds of systems software to consider:

  • -operating systems
  • -utilities
