An operating system manages the files stored on a computer.

Explain one purpose of file management in an operating system.

[2 marks]
Mark scheme

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

  • Files can be organised into folders/directories (1) so users can find/store files easily (1)
  • Files can be located/opened/saved (1) because the operating system keeps track of where each file is stored (1)
  • Access permissions can be set on files (1) so only allowed users can read/modify them (1)
  • Files can be copied/moved/deleted (1) because the operating system controls where data is written/removed on a storage device (1)
  • Free disk space can be monitored/managed (1) so storage does not run out / files are stored efficiently (1)

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

Do not accept 'manages files' or 'organises files' on its own as it repeats the question.

Allow 'makes it easier to find files' as the linked reason for organising files into folders.

Example answers and how they were marked
Full marks2/2

File management lets the operating system organise files into folders so that users can find the files they need more easily.

Why: Point (1) for organising files into folders and linked reason (1) for making files easier to find.

Some marks1/2

It organises files into folders.

Why: Point (1) for organising files into folders; no linked reason.

No marks0/2

It manages the files on the computer so the files are managed properly.

Why: Repeats the question; no purpose or linked reason credited.

A school has bought a new printer for one of its computers.

Explain one reason why an operating system needs peripheral management.

[2 marks]
Mark scheme

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

  • The operating system uses the printer's device driver to communicate with the printer (1) so the print job is sent as commands the printer can carry out (1)
  • The operating system holds print jobs in a queue/buffer (1) because the computer sends data faster than the printer can print it (1)
  • The operating system reports the printer's status to the user (1) so the user knows what to do when there is a problem such as the paper running out (1)
  • The operating system handles interrupts/signals from the printer (1) so a problem such as a paper jam is dealt with while other programs carry on running (1)

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

Allow a point about the operating system loading/installing the device driver for a new printer (1) provided the second mark gives a reason that is not the same as the driver communication point, e.g. so the new printer can be used/controlled by the operating system (1)

Award 1 mark for stating that print jobs are held in a queue/a buffer; the second mark needs the linked reason that the printer prints more slowly than data is sent.

Do not accept restating the question, e.g. 'it manages the printer' or 'it controls the peripherals', without saying how or why.

Do not accept 'it lets the printer connect to the computer' or 'it stops the printer being damaged' without a linked reason.

Do not accept 'it makes the printer print faster' as the operating system cannot increase the printer's speed.

Example answers and how they were marked
Full marks2/2

The operating system uses the printer's device driver to send the print job so the printer receives the data as commands it can understand.

Why: Linked point (1) and reason (1): device driver used to communicate, and the job is sent as commands the printer can carry out.

Some marks1/2

It puts print jobs into a queue.

Why: Point (1) only: the queue/buffer is named, but no linked reason (that the printer prints more slowly than data is sent) is given.

No marks0/2

It makes the printer print faster.

Why: Misconception named in the 'Do not accept' line: the operating system cannot increase the printer's speed, so there is no creditworthy point.
