1Short recall1 markSoftware Basics Swap Remove

A hard disk drive stores files in pieces in different places on the disk, so the files take longer to open.

Name the utility software that can be used to improve this.

[1 mark]
Mark scheme

Award one mark for:

  • Disk defragmentation (software) (1)

Allow defragmentation software, defragmenter, defrag.

Do not accept disk cleanup, disk formatter, file repair software or backup software.

Example answers and how they were marked
Full marks1/1

Disk defragmentation software.

Why: Names the correct utility software (1).

No marks0/1

Disk cleanup software.

Why: Disk cleanup is a near-miss: it is not the utility that rearranges files stored in pieces, so no mark is awarded.

No marks0/1

File repair software.

Why: File repair fixes damaged files and does not bring the pieces of a file back together, so no mark is awarded.

2Explain2 marksPurpose & Function of Operating Systems Swap Remove

A school has bought a new printer for one of its computers.

Explain one reason why an operating system needs peripheral management.

[2 marks]
Mark scheme

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

  • The operating system uses the printer's device driver to communicate with the printer (1) so the print job is sent as commands the printer can carry out (1)
  • The operating system holds print jobs in a queue/buffer (1) because the computer sends data faster than the printer can print it (1)
  • The operating system reports the printer's status to the user (1) so the user knows what to do when there is a problem such as the paper running out (1)
  • The operating system handles interrupts/signals from the printer (1) so a problem such as a paper jam is dealt with while other programs carry on running (1)

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

Allow a point about the operating system loading/installing the device driver for a new printer (1) provided the second mark gives a reason that is not the same as the driver communication point, e.g. so the new printer can be used/controlled by the operating system (1)

Award 1 mark for stating that print jobs are held in a queue/a buffer; the second mark needs the linked reason that the printer prints more slowly than data is sent.

Do not accept restating the question, e.g. 'it manages the printer' or 'it controls the peripherals', without saying how or why.

Do not accept 'it lets the printer connect to the computer' or 'it stops the printer being damaged' without a linked reason.

Do not accept 'it makes the printer print faster' as the operating system cannot increase the printer's speed.

Example answers and how they were marked
Full marks2/2

The operating system uses the printer's device driver to send the print job so the printer receives the data as commands it can understand.

Why: Linked point (1) and reason (1): device driver used to communicate, and the job is sent as commands the printer can carry out.

Some marks1/2

It puts print jobs into a queue.

Why: Point (1) only: the queue/buffer is named, but no linked reason (that the printer prints more slowly than data is sent) is given.

No marks0/2

It makes the printer print faster.

Why: Misconception named in the 'Do not accept' line: the operating system cannot increase the printer's speed, so there is no creditworthy point.

3Explain2 marksPurpose & Function of Operating Systems Swap Remove

A computer stores many files on its hard drive.

Explain one reason why an operating system needs file management.

[2 marks]
Mark scheme

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

  • The operating system keeps a record of where each file is stored (1) so files can be found/retrieved later (1)
  • The operating system keeps files in separate storage locations (1) so files are not overwritten/lost (1)
  • The operating system allocates files to folders/directories (1) so it can keep track of the files stored on the disk (1)
  • The operating system deletes/moves files (1) so storage space is freed/reused (1)

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

Do not accept 'it manages files'/'it organises files' without expansion as to what is managed or organised.

Do not accept 'so files are managed/organised' as the linked reason.

Do not accept 'so the computer works' as the linked reason.

Example answers and how they were marked
Full marks2/2

The operating system keeps a record of where each file is stored on the disk, so a program can find and open the file later.

Why: Linked point (1) and reason (1): record of file location and retrieval.

Some marks1/2

The operating system keeps a record of where each file is stored.

Why: Point (1) only; no linked reason given.

No marks0/2

The operating system manages the files so the files are managed.

Why: Repeats the question ('manages files') and the expansion restates the point ('so the files are managed'); no creditworthy point under the Do not accept lines.
