1Describe2 marksProcess Management Swap Remove

An operating system manages the processes running on a computer.

Describe the purpose of process management.

[2 marks]
Mark scheme

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

  • Decides which process is given use of the CPU (1) so that more than one program can run/appear to run at the same time (1)
  • Allocates CPU time to each process (1) so that no single process takes control of the CPU (1)
  • Manages the states/life-cycle of each process (1) so processes can be moved between ready/running/blocked (1)
  • Keeps track of the processes and their status (1) so a process waiting for a resource can be returned to the CPU when it is ready (1)

Do not accept responses that only describe what a process is.

Do not accept responses that only list the types of operating system management.

Example answers and how they were marked
Full marks2/2

It decides which process will use the CPU so that several programs can run without one taking over the processor.

Why: Decision about CPU use (1) linked to allowing several programs to run (1).

Some marks1/2

It decides which process uses the CPU.

Why: One creditworthy point about choosing a process for the CPU (1), but no linked development.

No marks0/2

It makes sure the computer has enough RAM to store files.

Why: Describes memory/file management, not process management; no creditworthy point.

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 computer stores many files on its hard drive.

Explain one reason why an operating system needs file management.

[2 marks]
Mark scheme

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

  • The operating system keeps a record of where each file is stored (1) so files can be found/retrieved later (1)
  • The operating system keeps files in separate storage locations (1) so files are not overwritten/lost (1)
  • The operating system allocates files to folders/directories (1) so it can keep track of the files stored on the disk (1)
  • The operating system deletes/moves files (1) so storage space is freed/reused (1)

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

Do not accept 'it manages files'/'it organises files' without expansion as to what is managed or organised.

Do not accept 'so files are managed/organised' as the linked reason.

Do not accept 'so the computer works' as the linked reason.

Example answers and how they were marked
Full marks2/2

The operating system keeps a record of where each file is stored on the disk, so a program can find and open the file later.

Why: Linked point (1) and reason (1): record of file location and retrieval.

Some marks1/2

The operating system keeps a record of where each file is stored.

Why: Point (1) only; no linked reason given.

No marks0/2

The operating system manages the files so the files are managed.

Why: Repeats the question ('manages files') and the expansion restates the point ('so the files are managed'); no creditworthy point under the Do not accept lines.
