1Short recall1 markUtility Software Swap Remove

Backup software is a type of utility software.

State one purpose of backup software.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • To make/keep a copy of files/data (1)
  • To store the copy separately from the original, e.g. on a different device/in a different location (1)
  • So that data can be restored if the original is lost/damaged/corrupted (1)

Do not accept "to save files" on its own, as saving is normal file management and does not make a separate copy.

Do not accept answers that describe a different utility, such as scanning for malware/viruses (anti-malware software).

Example answers and how they were marked
Full marks1/1

To make a copy of data so it can be restored if the original is lost.

Why: Copy of data (1); the restore point is also present but the maximum is one mark.

No marks0/1

To save files to a hard disk.

Why: Saving files is normal file management and does not make a separate copy; the mark scheme says not to accept this, so no mark.

No marks0/1

To scan files for viruses.

Why: Describes anti-malware software, a different utility; the mark scheme says not to accept answers about another utility, so no mark.

2Short recall3 marksUser Management Swap Remove

User management controls what a user can do on a computer.

State three resources that an operating system can limit for a standard user.

[3 marks]
Mark scheme

Award one mark for any of the following up to a maximum of three marks:

  • Storage space/disk space/disk quota (1)
  • Printer/printing (1)
  • Processor time/CPU time (1)
  • Memory/RAM (1)
  • Internet/network access/bandwidth (1)
  • Removable media/USB drives (1)
  • Software/applications/programs (including the ability to install programs) (1)

Allow 'access to removable media/USB drives'.

Do not accept 'files' or 'folders' on their own.

Do not accept 'passwords' or 'usernames'.

Do not accept 'hardware' on its own.

Example answers and how they were marked
Full marks3/3

Storage space, the printer and processor time.

Why: Storage space (1), printer (1) and processor time (1) are three accepted resources.

Some marks1/3

Storage space and hardware.

Why: Storage space (1); 'hardware' is too vague to be creditworthy on its own.

No marks0/3

Files, folders and passwords.

Why: Files and folders are not accepted on their own, and passwords are login details, not limited resources.

3Explain2 marksPurpose & Function of Operating Systems Swap Remove

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.
