UTILITY PROGRAMS FOR COMPUTER SECURITY

|
Spyware protection

|
Firewalls Monitors traffic entering the computer system to block unauthorised access (from hackers).
|
UTILITY PROGRAMS FOR DISK ORGANISATION
Formatting
Prepares new media (e.g. a flash drive) for receiving data.
|
File Transfer
Copies files from one location to another (FTP used to copy across a network)
|
Defragmenter
The memory on secondary storage (e.g. a hard disk drive) is divided into segments, but files are often larger than the size of a segment. So when files are saved, they are often split into ‘blocks’ across many segments. The defragmenter aims to bring these ‘blocks’ closer together making it quicker to access to the file.

Searches for and deletes files/programs which are no longer used (e.g. temporary files / installation files). Deletes settings / registry values which are no longer used.
