1Short 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.

2Describe2 marksProcess Management Swap Remove

The operating system creates a process when a program is opened.

Describe what the operating system does when it creates a process.

[2 marks]
Mark scheme

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

  • Allocates memory/RAM to the process (1) so its instructions and data can be stored (1)
  • Loads/moves the program instructions into RAM (1) so the process is ready to run (1)
  • Adds the process to the ready queue (1) so it can be scheduled onto the CPU (1)
  • Gives the process a process ID (PID)/identifier (1) so the operating system can track/manage it (1)

For both marks, the development must follow/be linked to the point.

Only award one of the first two bullets in any one response; allocating memory and loading into RAM are the same stage.

Accept 'memory' for 'RAM' and vice versa.

Accept 'added to a queue for the processor' for the ready queue point.

Do not accept responses that say the process is run on the CPU straight away.

Do not accept descriptions of the program executing/running its instructions, or of the program file being created/saved.

Do not accept responses about the process being blocked or terminated.

Example answers and how they were marked
Full marks2/2

It allocates memory to the process so its instructions and data can be stored.

Why: Allocates memory to the process (1) linked to storing its instructions and data (1).

Some marks1/2

It loads the program into RAM.

Why: Gives the creditworthy point that the program instructions are loaded into RAM (1), but does not develop the point.

No marks0/2

It runs the program on the CPU straight away.

Why: A newly created process is not normally run immediately; it becomes ready. This is explicitly not accepted, so no marks.

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.
