1Short recall2 marksMemory Management Swap Remove

The operating system keeps a record of where each program and its data are stored in main memory.

State two reasons why the operating system needs this record.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • So that it does not overwrite/use memory that is already being used by another program (1)
  • So that it can find the program/data again when the program needs it (1)
  • So that it knows which memory locations are free/can be allocated to a new program (1)
  • So that it can keep the data used by each program separate from other programs (1)
  • So that it can free the memory when the program is closed/knows which memory to release (1)

Do not accept 'so the program runs faster'.

Do not accept 'so that the program is not lost when the power is turned off' (this is about saving files to secondary storage, not main memory).

Example answers and how they were marked
Full marks2/2

So that the operating system does not put a new program on top of memory that another program is already using, and so that it can find the data again when the program needs it.

Why: Creditworthy point 'does not overwrite memory used by another program' (1) and 'find the program/data again when needed' (1).

Some marks1/2

It knows where the program is so it can find it again when it needs to run it.

Why: Creditworthy point 'find the program/data again when it is needed' (1); no second reason given.

No marks0/2

So that the program is not lost when the computer is switched off.

Why: This is about saving to secondary storage, not about a record of main memory locations; not a creditworthy reason, so no marks.

2Short recall2 marksUser Management Swap Remove

An operating system sets access rights for each file.

Give two access rights that can be set for a file.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • Read/view (1)
  • Write/edit/modify (1)
  • Execute/run (1)
  • Delete (1)

Allow 'read only' for read.

Treat write/edit/modify as one right only.

Do not accept 'open' or 'access' on its own.

Do not accept usernames/passwords (these are authentication, not file access rights).

Example answers and how they were marked
Full marks2/2

Read and write.

Why: Read (1) and write (1) are two separate accepted access rights.

Some marks1/2

Read-only.

Why: Read-only is allowed for read (1), but only one right is given.

No marks0/2

A username and a password.

Why: These are login details used for authentication, not access rights for a file, so no mark is awarded.

3Describe2 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.
