1Describe2 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.

2Describe2 marksPurpose & Function of Operating Systems Swap Remove

A computer in an office is used by several members of staff.

Describe how the operating system manages the users of the computer.

[2 marks]
Mark scheme

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

  • Stores a username and password/user account for each user (1) so that each user must log in before they can use the computer (1)
  • Stores each user's password in an encrypted form (1) so that another user cannot read it and log in as them (1)
  • Sets access rights/permissions for each user (1) so that a user can only open/see their own files (1)
  • Gives each user a different level of access (1) so that a system administrator can change settings that other users cannot (1)

Allow 'user accounts' as an alternative to a username and password, where a linked development is given.

Do not accept responses that only state that the operating system 'has passwords'/'has user accounts' or that 'the user logs in', with no linked development.

Do not accept responses about file management, such as creating folders or saving files, rather than user management.

Do not accept responses about keeping the computer safe from viruses, hackers or malware.

Ignore responses about the user interface.

Example answers and how they were marked
Full marks2/2

The operating system stores a username and password for each user so that each member of staff must log in before they can use the computer

Why: Linked point (1) - a username and password stored for each user - and development (1) - each user must log in before using the computer.

Some marks1/2

The operating system gives different users different access rights.

Why: Gives the point about access rights (1) but no linked development about what a user can then see or do.

No marks0/2

The operating system stops hackers from logging in by using a firewall.

Why: A firewall and protecting against hackers are not user management, so nothing is credited.
