A

Defragmentation is the process of rearranging data on a disk so that:
- Files are stored in blocks that are all together
- all the free storage space on the disk is brought together

18
Q

What is task scheduling?

A

There are 2 possible answers:
1. Timeslicing to get maximum use of processor
2. Set up tasks to run automatically at a given time, e.g.
backups, virus checks + software updates

19
Q

What is round-robin scheduling?

A

In multi-user systems using time-sharing, the processor executes a task from the first computer, then moves on to the next in sequence. When it reaches the last computer it will go back to the first computer and continue from there.

20
