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 marksUser Management Swap Remove

A computer can be used by more than one person.

Describe how an operating system uses access rights to protect each user's files.

[2 marks]
Mark scheme

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

  • Each user/file is given permissions/access rights (1) so other users cannot read/write/open/change that user's files (1)
  • A user may be given read-only/read access to a file (1) so they cannot edit/delete/change it (1)
  • Each file is given permissions/access rights for different users (1) so the operating system allows/refuses access depending on which user is logged in (1)
  • The operating system checks a user's permissions/access rights when a file is opened (1) so a user with read-only/read access cannot save/delete changes (1)

Do not accept responses about asking for a password/username, as this checks who the user is, not what they are allowed to do.

Do not accept 'files are protected/safe' or 'access rights protect files' without saying how access is limited (e.g. read-only access, permissions for different users).

Example answers and how they were marked
Full marks2/2

A user can be given read-only access to a file, so they can open it but cannot edit or delete it.

Why: Read-only/read access point (1) and linked development that the user cannot edit/delete the file (1).

Some marks1/2

A user can be given read-only access to a file.

Why: Read-only/read access point (1); no development saying what this prevents, such as being unable to edit/delete the file (0).

No marks0/2

The operating system asks for the password again before the file opens.

Why: Describes asking for a password, which checks who the user is, not access rights to the file; no creditworthy point.

4Explain2 marksPeripheral Management Swap Remove

A new printer is connected to a computer.

Explain the purpose of a device driver.

[2 marks]
Mark scheme

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

  • It allows the operating system/OS to communicate with the device/printer (1) because it translates the commands into signals the device understands (1)
  • It contains/sends the instructions/commands needed by a particular device (1) so the device carries out the correct actions (1)
  • It controls the device/printer (1) by sending commands/signals to it (1)
  • Different devices need different commands (1) so each one needs its own driver to work with the operating system (1)

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

Do not accept 'it drives/controls the device' on its own without saying how, e.g. by sending commands/signals.

Do not accept hardware/a physical device (a device driver is software).

Do not accept 'it connects the printer to the computer' or 'it installs the printer' without saying that it provides the instructions/commands for the device.

Example answers and how they were marked
Full marks2/2

It allows the operating system to send commands to the printer because it translates them into signals that the printer understands.

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

Some marks1/2

It contains the instructions that the printer needs.

Why: Point (1) but no linked reason.

No marks0/2

It is a piece of hardware that connects the printer to the computer.

Why: Misconception: a device driver is software, not hardware, and saying it connects the printer is not accepted without saying it provides the instructions/commands.
