2. Utilities

A utility is an application that has a very specific task to carry out related to the running of the system. It is often a small program in terms of programming code as it only needs to do one thing.

An operating system usually has lots of utilities integrated into it. For example:

  • De-fragmenting a hard disk
  • File compression
  • Testing memory performance
  • Network configuration
  • Network performance



Utilities are also available from third party suppliers which you can install yourself. They can be used for:

  • Handling zip files
  • Analysing disk useage
  • Backup utilities
  • Schedule tasks
  • Manage battery power
  • Anti-virus software
  • and many other tasks

Smart phones have many 'apps' that could be classed as utilities because they only do one thing, for example an app that uses the screen as a light source.
