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.

3Describe2 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.

4Explain2 marksProcess Management Swap Remove

A user opens a web browser.

Explain what the operating system does to get the browser's process ready to run.

[2 marks]
Mark scheme

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

  • A process is created for the program (1) so that its instructions can be loaded into RAM (1)
  • The process is put into the ready state (1) so that it can wait for the CPU to become available (1)
  • The operating system adds the process to a queue of ready processes (1) so the scheduler can choose it when the CPU is free (1)
  • The operating system allocates the resources the process needs (1) so that it can start running when it is given CPU time (1)

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

Allow 'main memory' for RAM.

Do not accept 'the browser is downloaded/loaded from the internet'.

Do not accept 'the program is run immediately on the CPU' without the ready step.

Example answers and how they were marked
Full marks2/2

It creates a process and loads the browser's instructions into RAM, then puts the process in the ready state to wait for CPU time.

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

Some marks1/2

It moves the program into RAM.

Why: A correct point (1) but no linked reason about the process being made ready.

No marks0/2

It runs the program straight away on the CPU.

Why: This describes the running state, not making the process ready, so no credit.
