1Short 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.

2Short 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.

3Explain2 marksMemory Management Swap Remove

When a program closes, the operating system frees the main memory it was using.

Explain one reason why the operating system frees main memory when a program closes.

[2 marks]
Mark scheme

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

  • The memory can be reused/allocated to another program (1) so other programs have enough main memory to run (1)
  • Freeing the memory stops main memory becoming full (1) so the computer can load/run new programs (1)
  • The closed program's data is no longer needed (1) so keeping it would waste main memory (1)
  • The operating system can give the freed memory to a program that needs more (1) so that program can continue to run (1)

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

Do not accept 'to make the computer faster' on its own without saying how freeing memory helps.

Do not accept 'to delete the program' or 'to save the program' because closing a program does not remove it from secondary storage.

Example answers and how they were marked
Full marks2/2

The memory can be reused by another program, so other programs have enough main memory to run.

Why: Linked point (1) about reusing the memory and reason (1) that other programs then have enough memory.

Some marks1/2

So that the memory is free.

Why: Gives the point (1) but does not give a linked reason saying what the free memory is used for.

No marks0/2

So the program is deleted from the computer.

Why: No creditworthy point; closing a program does not delete it from secondary storage.

4Explain2 marksPurpose & Function of Operating Systems Swap Remove

A computer stores many files on its hard drive.

Explain one reason why an operating system needs file management.

[2 marks]
Mark scheme

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

  • The operating system keeps a record of where each file is stored (1) so files can be found/retrieved later (1)
  • The operating system keeps files in separate storage locations (1) so files are not overwritten/lost (1)
  • The operating system allocates files to folders/directories (1) so it can keep track of the files stored on the disk (1)
  • The operating system deletes/moves files (1) so storage space is freed/reused (1)

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

Do not accept 'it manages files'/'it organises files' without expansion as to what is managed or organised.

Do not accept 'so files are managed/organised' as the linked reason.

Do not accept 'so the computer works' as the linked reason.

Example answers and how they were marked
Full marks2/2

The operating system keeps a record of where each file is stored on the disk, so a program can find and open the file later.

Why: Linked point (1) and reason (1): record of file location and retrieval.

Some marks1/2

The operating system keeps a record of where each file is stored.

Why: Point (1) only; no linked reason given.

No marks0/2

The operating system manages the files so the files are managed.

Why: Repeats the question ('manages files') and the expansion restates the point ('so the files are managed'); no creditworthy point under the Do not accept lines.
