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 recall2 marksPurpose & Function of Operating Systems Swap Remove

A computer can run more than one process at a time.

Give two tasks carried out by the process management function of an operating system.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • Deciding which process runs next on the CPU/scheduling processes (1)
  • Allocating processor/CPU time to processes/allowing multitasking (1)
  • Managing the process life-cycle/process states (ready, running, blocked) (1)
  • Handling interrupts so a running process is suspended and another can run (1)
  • Stopping/terminating a process when it has finished (1)

Do not accept 'managing processes' on its own.

Do not accept 'handling interrupts' on its own.

Do not award two marks for the same task expressed twice, e.g. 'deciding which process runs next' and 'scheduling processes', or 'allocating CPU time' and 'giving each process a share of processor time'.

Do not accept 'managing memory/memory management', 'managing files/file management' or 'managing devices/peripherals' (these are other functions of an operating system).

Example answers and how they were marked
Full marks2/2

Deciding which process runs next on the CPU and stopping a process when it has finished.

Why: Scheduling a process (1) and terminating a process (1) are two different named tasks.

Some marks1/2

Deciding which process runs next and scheduling processes.

Why: Both points are the same task expressed twice, so only one mark is awarded under the guidance.

No marks0/2

Managing processes and managing files.

Why: 'Managing processes' repeats the question and earns nothing; 'managing files' is file management, not process management, so it is not credited.

3Short recall3 marksUser Management Swap Remove

User management controls what a user can do on a computer.

State three resources that an operating system can limit for a standard user.

[3 marks]
Mark scheme

Award one mark for any of the following up to a maximum of three marks:

  • Storage space/disk space/disk quota (1)
  • Printer/printing (1)
  • Processor time/CPU time (1)
  • Memory/RAM (1)
  • Internet/network access/bandwidth (1)
  • Removable media/USB drives (1)
  • Software/applications/programs (including the ability to install programs) (1)

Allow 'access to removable media/USB drives'.

Do not accept 'files' or 'folders' on their own.

Do not accept 'passwords' or 'usernames'.

Do not accept 'hardware' on its own.

Example answers and how they were marked
Full marks3/3

Storage space, the printer and processor time.

Why: Storage space (1), printer (1) and processor time (1) are three accepted resources.

Some marks1/3

Storage space and hardware.

Why: Storage space (1); 'hardware' is too vague to be creditworthy on its own.

No marks0/3

Files, folders and passwords.

Why: Files and folders are not accepted on their own, and passwords are login details, not limited resources.
