what is a Utility
a key piece of system software integral to ensuring the consistent, high performance of the operating system.
Each utility program has a specific function linked to the maintenance of the operating system.
Compression
Compression is the process of reducing the size of a data file whilst still retaining most, or even all, of the original information.

Disk defragmentation
- As the hard disk becomes full, read/write times slow down.
- This is because files become fragmented as they are stored in different parts of memory.
- The disk defragmenter utility rearranges the contents of the hard drive so they can be accessed faster, thus improving performance.
Antivirus
Antivirus is responsible for detecting potential virus threats to the computer, alerting the user and removing these threats.
Automatic updating
This utility ensures the operating system is kept up to date.
any updates are automatically installed when the computer is restarted.
Updates tackle bugs or security flaws so this ensures the system is less vulnerable to malware and hacking threats.
Backup
The backup utility automatically creates routine copies of specific files selected by the user.
How often files are backed up is also specified by the user.
This means that in the event of a power failure, malicious attack or other accident, files can be recovered.
