1Describe2 marksUtility Software Swap Remove

A small business stores its customer records on a computer.

Describe the purpose of backup software.

[2 marks]
Mark scheme

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

  • Makes a copy/duplicate of the files/data (1) and stores it on a separate storage device/at a different location (1)
  • Copies the data at regular intervals (1) so a recent version is available if the original is lost (1)
  • Keeps a copy of the files (1) so that the data can be restored after the original is deleted/corrupted (1)
  • Stores the copies on another device (1) so the data is not lost if the original device fails/is damaged by a fire or flood (1)

Do not accept 'it backs up the files' on its own, as this repeats the question.

Do not accept responses about repairing corrupted files or removing malware, as these are different utility programs.

Example answers and how they were marked
Full marks2/2

It makes a copy of the data and saves it on a separate storage device so that the records can be restored if the original files are deleted or the computer fails.

Why: The point (1) and a linked development giving the purpose of the copy (1).

Some marks1/2

It makes a copy of the files and saves it on another disk.

Why: The point and location are given (1), but there is no development saying what the copy is used for, so no second mark.

No marks0/2

It repairs damaged files so that they can be opened again by the program.

Why: This describes file repair software, which the mark scheme does not accept for this question.

2Explain2 marksPeripheral Management Swap Remove

An operating system manages the peripherals connected to a computer.

Explain one reason why an operating system needs to manage peripheral devices.

[2 marks]
Mark scheme

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

  • Data is sent to/received from the correct peripheral (1) because the operating system controls the transfer of data between the computer and each device (1)
  • A new peripheral can be used as soon as it is connected (1) because the operating system installs/loads the correct device driver for that device (1)
  • Data can be sent to a slow peripheral such as a printer (1) because the operating system stores it in a buffer/print queue until the device is ready to receive it (1)
  • The user is told when a peripheral has a problem (1) because the operating system receives status information from the device and reports the error to the user (1)

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

Allow specific peripherals as the example (e.g. a mouse, a printer) provided the reason says what the operating system does.

Allow 'the operating system responds to an interrupt from a device' as a point, with the reason that the device is signalling that it needs attention/has finished its job.

Do not accept 'the operating system manages/controls the peripherals' or 'it lets the devices be used'/'the peripherals work correctly' on their own, as these repeat the question without saying what the operating system does.

Example answers and how they were marked
Full marks2/2

So that data is sent to the correct peripheral because the operating system controls the transfer of data between the computer and each device.

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

Some marks1/2

So that data is sent to the correct device.

Why: Point (1) but no linked reason, so the second mark is not awarded.

No marks0/2

Because the operating system manages the peripherals.

Why: Rewords the question; the 'Do not accept' line says this earns nothing without saying what the operating system does.

3Explain2 marksSoftware Basics Swap Remove

An operating system manages the files stored on a computer.

Explain one purpose of file management in an operating system.

[2 marks]
Mark scheme

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

  • Files can be organised into folders/directories (1) so users can find/store files easily (1)
  • Files can be located/opened/saved (1) because the operating system keeps track of where each file is stored (1)
  • Access permissions can be set on files (1) so only allowed users can read/modify them (1)
  • Files can be copied/moved/deleted (1) because the operating system controls where data is written/removed on a storage device (1)
  • Free disk space can be monitored/managed (1) so storage does not run out / files are stored efficiently (1)

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

Do not accept 'manages files' or 'organises files' on its own as it repeats the question.

Allow 'makes it easier to find files' as the linked reason for organising files into folders.

Example answers and how they were marked
Full marks2/2

File management lets the operating system organise files into folders so that users can find the files they need more easily.

Why: Point (1) for organising files into folders and linked reason (1) for making files easier to find.

Some marks1/2

It organises files into folders.

Why: Point (1) for organising files into folders; no linked reason.

No marks0/2

It manages the files on the computer so the files are managed properly.

Why: Repeats the question; no purpose or linked reason credited.
