Types of Software

Based on the goal, computer software can be divided into:

  • Application software
    which is software that uses the computer system to perform special functions or provide entertainment functions beyond the basic operation of the computer itself. There are many different types of application software because the range of tasks that can be performed with a modern computer is so large.
  • System software
    which is software that directly operates the computer hardware, to provide basic functionality needed by users and other software, and to provide a platform for running application software.System software includes:

    • Operating systems
      which are essentially collections of software that manage resources and provides common services for other software that runs “on top” of them. Supervisory programs, bootloaders, shells and window systems are core parts of operating systems. In practice, an operating system comes bundled with additional software (including application software) so that a user can potentially do some work with a computer that only has one operating system.
    • Malicious software or malware
      which is software that is developed to harm and disrupt computers. As such, malware is undesirable. Malware is closely associated with computer-related crimes, though some malicious programs may have been designed as practical jokes.
