Question 1

System software

System software includes Windows, Linux and OSX.

Question 3

Disk cleanup

Answer 3

When you run disk cleanup software it frees up space on your hard drive by deleting temporary files, emptying the recycling bin, removing components from previous windows installations and removing programs that you don’t use anymore.

Question 4

Disk backup

Answer 4

Keep your data safe by making a copy and keeping it in a safe location. This is also a part of disaster recovery. If your computer is stolen, your backup can be used as part of a disaster recovery programme. There are three types of backup techniques:

Full- backs up every thing on your computer.
Differential- backs up everything that’s changed since the last backup.
Incremental- similar to differential, but backs up only since the last incremental backup.

Question 5

Disk defragmentation

Answer 5

When a program is installed on your computer, the program’s files may be broken up over multiple locations on your hard drive. This is called fragmentation. Disk defragmentation optimises the performance of your computer by recognising the files on your hard drive into contiguous blocks.

Answer 6

Keeps the bad shit off your computer.
