Utility Software
Utility software performs a task (or set of tasks) that optimizes, repairs,
or safeguards the computer or its data. The difference between utility
software and the operating system is sometimes not clear-cut, because
most operating systems come with many utility programs built-in. For
example, Microsoft Windows comes with utilities for checking a disk for
errors and optimizing the way files are stored on an HDD (hard disk
drive). Third-party utility software is also available, and may do a more
thorough job at the task, combine multiple functions in a single inter-
face, or have more advanced options for configuring how the tasks will
run. Figure 4.3 shows the Norton Security Suite, which provides secu-
rity, identity protection, a backup utility, and a PC tune-up utility.

useful service to the operating system, such as
optimizing or correcting the file storage system,
backing up files, or ensuring security or privacy.
