1Short recall1 markSoftware Basics Swap Remove

A computer system runs both an operating system and utility software.

State one difference between an operating system and utility software.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • The operating system is needed/essential for the computer to run / utility software is optional (1)
  • The operating system manages the hardware/users/resources / utility software performs housekeeping tasks that keep the system running efficiently (1)
  • The operating system provides a platform for other software to run / utility software carries out extra/specific tasks (1)
  • Each utility program performs one specific task / the operating system carries out many different management tasks (1)
  • Utility software is often packaged with the operating system but can also be bought separately (1)

Do not accept answers that only give an example of each (e.g. Windows, anti-malware) without stating a difference.

Do not accept the operating system is hardware.

Example answers and how they were marked
Full marks1/1

The operating system is needed for the computer to work, but the utility software is optional.

Why: States a creditworthy difference: essential versus optional (1).

No marks0/1

Windows is an operating system and anti-malware is utility software.

Why: This only gives an example of each and does not state a difference, so no mark is awarded.

No marks0/1

The operating system is hardware and the utility software is software.

Why: The operating system is software, not hardware, so the answer contains no creditworthy difference.

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 marksPeripheral Management Swap Remove

An operating system manages the peripherals connected to a computer.

Explain one reason why an operating system needs to manage peripheral devices.

[2 marks]
Mark scheme

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

  • Data is sent to/received from the correct peripheral (1) because the operating system controls the transfer of data between the computer and each device (1)
  • A new peripheral can be used as soon as it is connected (1) because the operating system installs/loads the correct device driver for that device (1)
  • Data can be sent to a slow peripheral such as a printer (1) because the operating system stores it in a buffer/print queue until the device is ready to receive it (1)
  • The user is told when a peripheral has a problem (1) because the operating system receives status information from the device and reports the error to the user (1)

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

Allow specific peripherals as the example (e.g. a mouse, a printer) provided the reason says what the operating system does.

Allow 'the operating system responds to an interrupt from a device' as a point, with the reason that the device is signalling that it needs attention/has finished its job.

Do not accept 'the operating system manages/controls the peripherals' or 'it lets the devices be used'/'the peripherals work correctly' on their own, as these repeat the question without saying what the operating system does.

Example answers and how they were marked
Full marks2/2

So that data is sent to the correct peripheral because the operating system controls the transfer of data between the computer and each device.

Why: Linked point (1) and reason (1).

Some marks1/2

So that data is sent to the correct device.

Why: Point (1) but no linked reason, so the second mark is not awarded.

No marks0/2

Because the operating system manages the peripherals.

Why: Rewords the question; the 'Do not accept' line says this earns nothing without saying what the operating system does.
