1Short recall1 markSoftware Basics Swap Remove

A hard disk drive stores files in pieces in different places on the disk, so the files take longer to open.

Name the utility software that can be used to improve this.

[1 mark]
Mark scheme

Award one mark for:

  • Disk defragmentation (software) (1)

Allow defragmentation software, defragmenter, defrag.

Do not accept disk cleanup, disk formatter, file repair software or backup software.

Example answers and how they were marked
Full marks1/1

Disk defragmentation software.

Why: Names the correct utility software (1).

No marks0/1

Disk cleanup software.

Why: Disk cleanup is a near-miss: it is not the utility that rearranges files stored in pieces, so no mark is awarded.

No marks0/1

File repair software.

Why: File repair fixes damaged files and does not bring the pieces of a file back together, so no mark is awarded.

2Describe2 marksPeripheral Management Swap Remove

A computer is connected to a new games controller.

Describe the purpose of a device driver.

[2 marks]
Mark scheme

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

  • A device driver is software/program (1) that controls a peripheral device (1)
  • It translates instructions from the operating system (1) into commands/signals the device understands (1)
  • It allows the operating system to communicate with a specific device (1) without needing to know the device's hardware details (1)
  • It is installed for a new device (1) so the operating system can use that device (1)

Do not accept responses that say a device driver is hardware or that it makes a device faster.

Do not award 'it is part of the CPU'.

Example answers and how they were marked
Full marks2/2

A device driver is a program that controls a peripheral device. It translates instructions from the operating system into commands the device understands.

Why: Gives the linked description: software/program (1) that controls a peripheral (1).

Some marks1/2

It translates instructions from the operating system.

Why: Gives the first point (1) but does not develop it into commands/signals the device understands.

No marks0/2

A device driver is a piece of hardware that connects the controller to the computer.

Why: No credit: says a device driver is hardware, which the mark scheme does not accept.

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.
