Utility software

1.5.2a

What you need to know

Utility software performs additional 'housekeeping' tasks to maintain and optimise the computer system. These tasks supplement the operating system's functions and help keep the system running efficiently.

Key points

  • Definition:Utility Software: programs that perform maintenance and optimisation tasks to support the efficient running of the computer system.
  • Utility software supplements the OS — it performs tasks the OS may not handle directly.
  • Computers often come with utility software pre-installed.
  • Examples include: encryption software, defragmentation software, data compression software.
  • Exam Tip:Utility software is NOT the operating system — it is additional software that helps maintain and optimise the system.
  • Definition:Purpose of utility software: to perform housekeeping tasks / monitor, manage, and maintain a computer system / help the computer run smoothly and efficiently.
  • Common Mistake:When asked 'what is the need for utility software', giving a specific example like 'defragmentation' instead of the GENERAL purpose. The answer is: 'to maintain and optimise the computer system'.
