1Short recall2 marksFile Management Swap Remove

An operating system manages the files stored on a computer.

State two ways the operating system manages where files are stored on the disk.

[2 marks]
Mark scheme

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

  • Decides/allocates which part/space on the disk a file is written to (1)
  • Keeps an index/record of the location of each file so that it can be found/retrieved (1)
  • Prevents a file from being overwritten by another file (1)
  • Checks there is enough free space on the disk before a file is saved (1)

Allow 'file allocation table' for keeping an index/record of file locations

Only award one mark for answers that say the operating system decides/allocates where a file is stored or allocates free space on the disk

Do not accept defragmentation

Do not accept 'stores files', 'saves files' or 'backs up files' (these only repeat the stem)

Do not accept 'organises files into folders' on its own

Do not accept scheduling processes or managing peripherals

Example answers and how they were marked
Full marks2/2

It keeps an index of where each file is stored so it can be found again, and it stops a new file overwriting an existing file.

Why: Keeps an index of file locations so files can be retrieved (1) and prevents a file being overwritten (1).

Some marks1/2

It keeps a record of where each file is stored.

Why: Keeps an index/record of file locations (1), but does not give a second way.

No marks0/2

It saves files on the hard disk and organises them into folders.

Why: 'Saves files' only repeats the stem and 'organises files into folders' on its own is not accepted, so no creditworthy point is given.

2Short 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.

3Describe2 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.
