Utility software are programs that have been made to help a computer run more efficiently
Compression Software
There are two uses of compression:
Less storage: Compression reduces the size of files meaning less space is taken up
Faster speeds: Compressed files have faster upload and download times
It is used in the case of fire, theft or other computer error
Defragmentation
Files can become fragmented which means they are spread far apart over the hard disk
Defragmentation brings the fragments together making the files quicker to access
Backup Software
There are two types of backup software:
Full: Backup of all files, usually done weekly
Incremental: New and used files only, usually done daily
It is used in the case of fire, theft or other computer error
Encryption
Plain text can be encrypted with a key, this turns it into cipher text
The text cannot be decrypted without that key
Antivirus
Antivirus scans a device and quarantines or deletes suspicious files
The software must be updated regularly as new viruses are constantly being made
