1Short recall1 markUtility Software Swap Remove

A file may become corrupted and cannot be opened.

State the purpose of file repair software.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • To repair/recover corrupted/damaged files so they can be opened/used again (1)
  • To recover as much of the data as possible from a damaged file (1)
  • To reconstruct parts of a damaged file (1)

Allow "to fix corrupted files".

Do not accept "to repair the hard disk" (disk repair).

Do not accept "to recover deleted files" (file repair recovers corrupted/damaged files, not deleted ones).

Example answers and how they were marked
Full marks1/1

To repair corrupted files so they can be opened again.

Why: Repair corrupted files so they can be used again (1).

No marks0/1

To repair the hard disk.

Why: Hard disk repair is not file repair; the scheme says not to accept it.

No marks0/1

To recover files that have been deleted.

Why: Recovering deleted files is not file repair; the scheme says not to accept it.

2Short recall2 marksPurpose & Function of Operating Systems Swap Remove

An operating system manages the peripheral devices connected to a computer.

State two tasks carried out by the peripheral management function of an operating system.

[2 marks]
Mark scheme

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

  • Receives input from/sends output to peripheral devices (1)
  • Communicates with/controls a peripheral using its device driver, including installing the driver for a new device (1)
  • Manages the print queue/buffer so that print jobs are sent to the printer in turn (1)
  • Reports the status of a device/a device error to the user, e.g. out of paper (1)

Allow answers that name a specific peripheral, as long as they also say what the operating system does with it, e.g. 'it controls the printer using its driver'.

Do not accept 'manages peripherals'/'controls the hardware' on its own, as this repeats the question.

Do not accept 'managing files' or 'managing users' (file management and user management are other functions of an operating system).

Example answers and how they were marked
Full marks2/2

It uses device drivers to control each peripheral and it reports a printer error such as out of paper to the user.

Why: Communicating with a peripheral using its device driver (1) and reporting a device error to the user (1) are two different peripheral management tasks.

Some marks1/2

It manages the print queue.

Why: Managing the print queue is one named peripheral management task (1); no second task is given.

No marks0/2

It manages peripherals and it manages users.

Why: 'Manages peripherals' repeats the question and earns nothing; 'manages users' is user management, not peripheral management.

3Describe2 marksFile Management Swap Remove

A user saves a new file into a folder that already contains files.

Describe how the operating system prevents a new file overwriting an existing file.

[2 marks]
Mark scheme

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

  • Checks/compares the new file (name)/filename against the names of files already in the folder/directory (1) to see if the name is already in use (1)
  • Refuses to save/allow the new file when the (file) name already exists (1) so the existing file is not replaced/overwritten (1)
  • Prompts/asks the user to choose/enter a different (file) name (1) so both files can be saved without one replacing the other (1)

A point without a linked development can earn one mark.

For both marks, the development must follow/associate with the point.

Do not accept responses about defragmentation.

Do not accept the operating system making a backup copy, or warning the user that a file may be overwritten, without saying that the (file) name is checked or the new file is not saved.

Do not accept responses about process management or saving files to RAM.

Do not award a second mark for repeating the question, e.g. 'it stops the new file overwriting the existing file'.

Example answers and how they were marked
Full marks2/2

It checks the new file name against the names of files already in the folder to see whether the name is already in use.

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

Some marks1/2

It checks the file name against the names already in the folder.

Why: Creditworthy point (1) on its own; no linked development, so one mark.

No marks0/2

It defragments the disk so there is room for the new file.

Why: Defragmentation is not accepted by the mark scheme.

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.
