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.

2Describe2 marksFile Management Swap Remove

A user deletes an unwanted file from their computer.

Describe what happens when the file is deleted.

[2 marks]
Mark scheme

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

  • The file's entry is removed from the folder/directory (1) so the file no longer appears in the list of files/is no longer listed (1)
  • The (disk) space used by the file is marked as free/available/unused (1) so another file can be saved/stored in that space (1)
  • The file's data/contents are not erased/removed (1) so the file may still be recovered until the space is overwritten (1)

A point stated without development, e.g. 'the file is removed from the folder', earns one mark only.

For the first mark, accept that the file's entry is removed from the folder/directory; the second mark must state that the file no longer appears/is listed.

Do not accept 'stays on disk' alone for the third point; accept 'data is not erased' or 'contents remain'.

Do not accept 'the file is wiped from the disk straight away' or 'the data is destroyed and can never be recovered'.

Do not accept 'the file is moved to the recycle bin/bin' or 'the file is deleted from the hard drive' on its own, as this does not describe what happens to the file or the disk space.

Do not accept responses about moving the file to another folder.

Example answers and how they were marked
Full marks2/2

The space the file used is marked as free so another file can be saved in that space.

Why: Linked point (1) and development (1): space marked free and another file can be saved.

Some marks1/2

The file is removed from the folder.

Why: Point (1) only; no development about the file no longer being listed.

No marks0/2

The data is wiped from the disk straight away so it can never be recovered.

Why: Common misconception; 'wiped straight away' is not accepted, so no mark.

3Describe2 marksUtility Software Swap Remove

A hard disk can become fragmented as files are saved and deleted.

Describe how disk defragmentation software improves the performance of a hard disk.

[2 marks]
Mark scheme

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

  • Parts of a file are moved so they are stored together/in consecutive locations (1) so the read/write head has less distance to travel to read the file (1)
  • Files are rearranged so that each file is stored in one block (1) which reduces the time taken to open/load the file (1)
  • Free space on the disk is collected into one area (1) so new files can be saved without becoming fragmented (1)
  • The parts of each fragmented file are put in order (1) so fewer movements of the read/write head are needed to read it (1)

Do not accept responses about compressing files, deleting files or increasing the amount of storage, as these are not what defragmentation software does.

Do not accept 'it makes the disk faster' without saying how the files are changed.

Example answers and how they were marked
Full marks2/2

It moves the parts of a file so they are stored together in consecutive locations, so the read/write head does not have to move as far and the file opens more quickly.

Why: Linked point (1) and development (1): the file parts are stored together, which reduces read/write head movement.

Some marks1/2

It reorganises the files on the hard disk so that they are stored together.

Why: The point is made (1) but there is no development saying how this improves performance, so the second mark is not awarded.

No marks0/2

It compresses the files so that they take up less space on the disk.

Why: This describes data compression software, which the mark scheme says is not accepted; no creditworthy point is made.
