1Short recall1 markUtility Software Swap Remove

A file may become corrupted and cannot be opened.

State the purpose of file repair software.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • To repair/recover corrupted/damaged files so they can be opened/used again (1)
  • To recover as much of the data as possible from a damaged file (1)
  • To reconstruct parts of a damaged file (1)

Allow "to fix corrupted files".

Do not accept "to repair the hard disk" (disk repair).

Do not accept "to recover deleted files" (file repair recovers corrupted/damaged files, not deleted ones).

Example answers and how they were marked
Full marks1/1

To repair corrupted files so they can be opened again.

Why: Repair corrupted files so they can be used again (1).

No marks0/1

To repair the hard disk.

Why: Hard disk repair is not file repair; the scheme says not to accept it.

No marks0/1

To recover files that have been deleted.

Why: Recovering deleted files is not file repair; the scheme says not to accept it.

2Short recall1 markSoftware Basics Swap Remove

A computer system runs both an operating system and utility software.

State one difference between an operating system and utility software.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • The operating system is needed/essential for the computer to run / utility software is optional (1)
  • The operating system manages the hardware/users/resources / utility software performs housekeeping tasks that keep the system running efficiently (1)
  • The operating system provides a platform for other software to run / utility software carries out extra/specific tasks (1)
  • Each utility program performs one specific task / the operating system carries out many different management tasks (1)
  • Utility software is often packaged with the operating system but can also be bought separately (1)

Do not accept answers that only give an example of each (e.g. Windows, anti-malware) without stating a difference.

Do not accept the operating system is hardware.

Example answers and how they were marked
Full marks1/1

The operating system is needed for the computer to work, but the utility software is optional.

Why: States a creditworthy difference: essential versus optional (1).

No marks0/1

Windows is an operating system and anti-malware is utility software.

Why: This only gives an example of each and does not state a difference, so no mark is awarded.

No marks0/1

The operating system is hardware and the utility software is software.

Why: The operating system is software, not hardware, so the answer contains no creditworthy difference.

3Explain2 marksProcess Management Swap Remove

A computer has a single CPU.

Explain how the operating system allows a user to run several programs at the same time.

[2 marks]
Mark scheme

Award up to two marks for a linked explanation such as:

  • The operating system switches rapidly between processes (1) so each process runs for a short time slice before the next one starts (1)
  • Each process is given a small amount of CPU time (1) so the CPU moves on to another process when that time is up (1)
  • The operating system chooses which process to run next (1) so the CPU is shared between the programs (1)
  • Processes take turns to use the CPU (1) because the CPU is so fast the user does not notice the switching (1)
  • Only one process can run on the CPU at a time (1) so the operating system must swap processes in and out quickly (1)

For both marks, the expansion must follow/associate with the statement.

Allow 'time slice' / 'time quantum'.

Do not accept 'the computer has more than one CPU' / 'each program runs on its own CPU'.

Do not accept 'the CPU does two things at once' without saying processes take turns/are switched.

Example answers and how they were marked
Full marks2/2

The operating system switches rapidly between processes, giving each one a small time slice, so the CPU is shared and the programs appear to run together.

Why: Linked point (1) and reason (1).

Some marks1/2

Each process is given a small amount of CPU time.

Why: A correct point (1) but no linked reason.

No marks0/2

The computer has two CPUs so each program can run on its own processor.

Why: The scenario states a single CPU, so this misconception earns no credit.
