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.

2Describe2 marksPurpose & Function of Operating Systems Swap Remove

A laptop stores many files on its hard disk.

Describe one way the operating system manages the files on the laptop.

[2 marks]
Mark scheme

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

  • Keeps a record/index of where each file is stored on the disk (1) so that the file can be found and opened when it is needed (1)
  • Allocates each file to a folder/directory (1) so that files used for the same purpose are kept together (1)
  • Decides where on the disk each new file is written (1) so that it does not overwrite an existing file (1)
  • Allocates space on the disk for a file (1) so that the file has somewhere to be saved (1)

Allow 'files are organised into folders so that they are easy to find', with the folder point (1) and its purpose (1).

Do not accept responses that only state that the operating system 'organises' or 'controls' the files, with no way of doing it given.

Do not accept 'stores the files' or 'saves files to the disk' without a way of doing it.

Do not accept responses about backing files up, or about the amount of storage space left on the disk.

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 that the file can be found and opened again later

Why: Linked point (1) - keeps a record of where each file is stored - and development (1) - so the file can be found later.

Some marks1/2

The operating system puts the files into folders.

Why: Gives the point that each file is allocated to a folder (1) but no linked development about why files are grouped.

No marks0/2

The operating system backs up the files to the cloud so that they are not lost.

Why: Backing up is not file management on this specification, so no point or development is credited.

3Explain2 marksMemory Management Swap Remove

When a program closes, the operating system frees the main memory it was using.

Explain one reason why the operating system frees main memory when a program closes.

[2 marks]
Mark scheme

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

  • The memory can be reused/allocated to another program (1) so other programs have enough main memory to run (1)
  • Freeing the memory stops main memory becoming full (1) so the computer can load/run new programs (1)
  • The closed program's data is no longer needed (1) so keeping it would waste main memory (1)
  • The operating system can give the freed memory to a program that needs more (1) so that program can continue to run (1)

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

Do not accept 'to make the computer faster' on its own without saying how freeing memory helps.

Do not accept 'to delete the program' or 'to save the program' because closing a program does not remove it from secondary storage.

Example answers and how they were marked
Full marks2/2

The memory can be reused by another program, so other programs have enough main memory to run.

Why: Linked point (1) about reusing the memory and reason (1) that other programs then have enough memory.

Some marks1/2

So that the memory is free.

Why: Gives the point (1) but does not give a linked reason saying what the free memory is used for.

No marks0/2

So the program is deleted from the computer.

Why: No creditworthy point; closing a program does not delete it from secondary storage.
