1Short recall2 marksPurpose & Function of Operating Systems Swap Remove

A home computer can have more than one user account.

Name two tasks carried out by the user 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:

  • Creating/deleting user accounts (1)
  • Storing usernames and passwords (1)
  • Checking login details/authenticating a user at login (1)
  • Setting access rights/permissions for each user, e.g. restricting which files/folders/programs/drives they can access (1)

Allow logging in as an example of checking login details.

Do not accept managing users on its own.

Do not accept provides a user interface, as this is not user management.

Do not accept managing files or managing processes, as these are other functions.

Do not accept stopping hackers/protecting from malware, as this is security, not user management.

Example answers and how they were marked
Full marks2/2

It stores usernames and passwords and sets access rights for each user.

Why: Storing usernames and passwords (1) and setting access rights (1) are two different user management tasks.

Some marks1/2

It checks the password at login and manages users.

Why: Checking a password at login earns (1); managing users repeats the question and earns nothing.

No marks0/2

It manages users and stops hackers accessing the computer.

Why: Managing users repeats the question; stopping hackers is security, not user management.

2Describe2 marksUser Management Swap Remove

A school laptop is shared by several teachers.

Describe the purpose of giving each teacher their own user account on the laptop.

[2 marks]
Mark scheme

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

  • Each teacher can keep their own files/desktop separate (1) so other teachers cannot see or change their work (1)
  • Each teacher's work is saved under their own account (1) so they can find their files easily when they log in (1)
  • The operating system knows which teacher is logged in (1) so it can apply the right access rights to that person (1)
  • Each teacher can set up their own desktop/settings (1) so the laptop is set up the way they like to work (1)

Do not accept responses about the laptop running faster or having more storage because it has more accounts.

Do not accept 'so they can log in' without saying why having separate accounts helps.

Example answers and how they were marked
Full marks2/2

Each teacher's files are stored separately, so other teachers cannot open or change their work.

Why: Separate files for each account (1) and other teachers kept out of that work (1).

Some marks1/2

So that each teacher has their own files.

Why: First point of separate files per account (1), but no development of what this achieves (0).

No marks0/2

So the laptop runs faster because each teacher has their own account.

Why: Gives speed as a purpose of user accounts, which is not correct for user management; no creditworthy point.

3Discuss6 marksFile Management Swap Remove

A student keeps school work and photographs on a laptop. The laptop's storage is almost full. The student uses the operating system's file management.

Discuss the file management tasks the operating system provides that the student can use to manage these files.

Your answer should include:

  • saving files
  • deleting files
  • copying files
[6 marks]
Mark scheme

Indicative content

Saving files

  • When saving, the operating system lets the student choose the folder and the file name, so new work goes into the correct subject folder instead of the root.
  • The operating system warns the student before a file with the same name is overwritten, so an earlier version of an essay is not lost by accident.
  • The operating system writes the file into free space on the laptop and records where it is, so the student can open it again later.

Deleting files

  • The operating system lets the student delete files that are no longer needed, which frees space so new photographs can be saved.
  • Deleted files are usually moved to the recycle bin first, so a file removed by mistake can be restored.
  • Emptying the recycle bin removes the data permanently and releases the space for other files.

Copying files

  • The operating system lets the student copy files to a USB flash drive, so there is a second copy if the laptop is lost or damaged.
  • Copying leaves the original file in place, so the student can carry on working on the laptop's copy.
  • A whole folder can be copied in one action, including its subfolders, which is quicker than copying each file separately.

Levels

  • Level 0 (0 marks): No rewardable content.
  • Level 1 (1–2 marks): Basic, independent points are made, showing elements of understanding of key concepts/principles of computer science. (AO1) The discussion will contain basic information with little linkage between points made or application to the context. (AO2)
  • Level 2 (3–4 marks): Demonstrates adequate understanding of key concepts/principles of computer science. (AO1) The discussion shows some linkages and lines of reasoning with some structure and application to the context. (AO2)
  • Level 3 (5–6 marks): Demonstrates comprehensive understanding of key concepts/principles of computer science to support the discussion being presented. (AO1) The discussion is well developed, with sustained lines of reasoning that are coherent and logically structured, and which clearly apply to the context. (AO2)

Level 3 responses must cover saving, deleting and copying.

Do not accept answers about the processor or defragmentation as file management tasks.

Example answers and how they were marked
Full marks6/6

When the student saves a file, the operating system lets them pick the folder and name, and it warns before a file with the same name is overwritten, so an earlier essay is not lost. Because the laptop is nearly full, the student can delete photographs they no longer need; these go to the recycle bin at first, so a file removed by mistake can be restored, and emptying the bin releases the space for good. The student can also copy their school work to a USB flash drive, which leaves the original on the laptop and gives a backup if the laptop is damaged.

Why: Saving (choice of folder and name, overwrite warning), deleting (recycle bin, restoring, releasing space) and copying (backup on a USB drive, original kept) are all explained and tied to the student's full laptop.

Some marks3/6

The student can save files into folders so they know where they are. They can delete files they do not need to free up space. They can copy files onto a memory stick.

Why: Three tasks are named with a reason for deleting, but saving and copying are not developed and there is little linkage between the points, so Level 2.

No marks0/6

The operating system saves files automatically and deletes old files when the RAM is full. The processor copies the files to the hard disk.

Why: No creditworthy point: files are not saved automatically, RAM filling does not trigger file deletion, and copying is not done by the processor. Typical confusion between file management and memory or processor management.
