Utility Software
Utility software is a subset of system software. Utility software programs perform specific tasks to help maintain the system. There are four main types of utility software:
Defragmentation
- This process involves improving hard disk performance by applying an algorithm to reorganise data.
Encryption
- This process is designed to prevent unauthorised access to files by applying an algorithm to "scramble" data.
Backup
- This process involves making copies of data that can be restored in the event of a data loss.
Compression
- This process involves applying an algorithm to reduce the space needed to represent a file or its contents.
