1Short recall2 marksFile Management Swap Remove

A user stores documents on a computer.

Give two tasks that file management allows the user to perform on a file.

[2 marks]
Mark scheme

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

  • Creating a file (1)
  • Opening a file (1)
  • Naming/renaming a file (1)
  • Saving a file (1)
  • Copying a file (1)
  • Moving a file (1)
  • Deleting a file (1)

Allow rename for renaming

Allow cut and paste for moving

Allow remove for deleting

Do not accept organising files or managing files on their own, without a named task

Do not accept file management, working with files, process management, user management

Example answers and how they were marked
Full marks2/2

Renaming a file and deleting a file.

Why: Names renaming (1) and deleting (1), two file management tasks.

Some marks1/2

Saving a file.

Why: Names one file management task (1).

No marks0/2

Organising files and managing processes.

Why: Organising files without a named task is not credited, and process management is another operating system function, not a task performed on a file.

2Explain2 marksProcess Management Swap Remove

A computer has a single CPU.

Explain how the operating system allows a user to run several programs at the same time.

[2 marks]
Mark scheme

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

  • The operating system switches rapidly between processes (1) so each process runs for a short time slice before the next one starts (1)
  • Each process is given a small amount of CPU time (1) so the CPU moves on to another process when that time is up (1)
  • The operating system chooses which process to run next (1) so the CPU is shared between the programs (1)
  • Processes take turns to use the CPU (1) because the CPU is so fast the user does not notice the switching (1)
  • Only one process can run on the CPU at a time (1) so the operating system must swap processes in and out quickly (1)

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

Allow 'time slice' / 'time quantum'.

Do not accept 'the computer has more than one CPU' / 'each program runs on its own CPU'.

Do not accept 'the CPU does two things at once' without saying processes take turns/are switched.

Example answers and how they were marked
Full marks2/2

The operating system switches rapidly between processes, giving each one a small time slice, so the CPU is shared and the programs appear to run together.

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

Some marks1/2

Each process is given a small amount of CPU time.

Why: A correct point (1) but no linked reason.

No marks0/2

The computer has two CPUs so each program can run on its own processor.

Why: The scenario states a single CPU, so this misconception earns no credit.
