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'.
