1Short recall2 marksSoftware Basics Swap Remove

Utility software helps to keep a computer system running efficiently.

State two examples of utility software.

[2 marks]
Mark scheme

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

  • File repair (software) (1)
  • Backup (software) (1)
  • Data compression (software) (1)
  • Disk defragmentation (software) (1)
  • Anti-malware (software) (1)

Allow antivirus software.

Do not accept file management, process management, peripheral management or user management, as these are functions of the operating system.

Do not accept operating systems (e.g. Windows, Linux) or application software (e.g. word processor, web browser).

Example answers and how they were marked
Full marks2/2

Anti-malware software and backup software.

Why: Two creditworthy examples from the list, one mark each (1) + (1).

Some marks1/2

Anti-malware software and file management software.

Why: Anti-malware software earns one mark (1); file management is a function of the operating system, so it is not a second mark.

No marks0/2

Windows and a word processor.

Why: Windows is an operating system and a word processor is application software, so neither is utility software and no mark is awarded.

2Short recall2 marksFile Management Swap Remove

An operating system provides file management.

Define the term file management.

[2 marks]
Mark scheme

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

  • The part/function of the operating system (1)
  • That manages/organises files (and folders) (1)
  • On a storage device/disk (1)
  • So files can be stored/found/retrieved (1)

Do not accept managing processes/peripherals/users as the whole definition.

Example answers and how they were marked
Full marks2/2

The function of the operating system that organises files and folders on a disk so they can be found and retrieved.

Why: Names the operating system function (1) and managing/organising files on a disk so they can be retrieved (1).

Some marks1/2

Organising files.

Why: Names managing/organising files (1), but does not name the operating system, storage location or retrieval.

No marks0/2

Managing the CPU and peripherals.

Why: Describes process and peripheral management, not file management.

3Describe2 marksMemory Management Swap Remove

The operating system is held in main memory while the computer is running.

Describe how the operating system stops a running program from overwriting memory that is not its own.

[2 marks]
Mark scheme

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

  • It keeps a record of which memory addresses/areas belong to each program and to the operating system (1) so it knows which addresses a program is allowed to use (1)
  • Each program is given its own area of main memory (1) so a program cannot write to the addresses used by another program or by the operating system (1)
  • The memory used by the operating system is marked as protected/reserved (1) so a program that tries to write to it is blocked/causes an error (1)
  • The address a program writes to is checked against the record of its allocated area (1) and the write is stopped if the address is outside that area (1)

Allow the memory being protected to be that of the operating system or of another program.

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

Do not award generic answers such as 'the operating system manages memory' or 'the operating system keeps track of memory'.

Do not award responses about stopping programs using too much memory or allocating memory, as these are not about protecting memory being overwritten.

Do not award responses about virtual memory, paging or moving processes to secondary storage.

Do not award responses about firewalls, antivirus software or passwords.

Example answers and how they were marked
Full marks2/2

The operating system gives each program its own area of main memory so that a program cannot write to the addresses used by another program or by the operating system.

Why: Each program is given its own area of main memory (1) linked to it not being able to write to the addresses used by another program or the operating system (1).

Some marks1/2

The operating system gives each program its own area of main memory.

Why: Each program is given its own area of main memory (1), but there is no linked development saying how this stops a program overwriting memory that is not its own.

No marks0/2

The operating system stops a program overwriting memory by moving it into virtual memory when it uses too much.

Why: This describes virtual memory and limiting how much memory a program uses, not protecting memory from being overwritten, so neither bullet applies and the Do not award lines rule it out.
