3.7 Utility Software

Utility software is a kind of system software designed to help analyze, configure, optimize
and maintain the computer. A single piece of utility software is usually called a utility (abbr.
util) or tool.
Utility software should be contrasted with application software, which allows users to do things
like creating text documents, playing games, listening to music or surfing the web. Rather than
providing these kinds of user-oriented or output-oriented functionality, utility software usually
focuses on how the computer infrastructure (including the computer hardware, operating system,
and application software and data storage) operates. Due to this focus, utilities are often rather
technical and targeted at people with an advanced level of computer knowledge.
