Anti-malware software helps keep a computer secure.

State two functions of anti-malware software.

[2 marks]
Mark scheme

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

  • Scans files/downloads/the computer/system for malware (1)
  • Compares files/code against a database of known malware/signatures/definitions (1)
  • Quarantines/removes/deletes infected/suspicious files/malware (1)
  • Prevents/blocks malware from running/being installed (1)
  • Updates the database of malware definitions/signatures (1)

Allow removes/deletes malware for the quarantines/removes bullet.

Do not award both quarantining and removing infected files as two separate functions; they are one function.

Do not award both scanning and preventing/blocking malware if the answer describes real-time scanning that blocks malware; award one only.

Do not accept protects the computer on its own.

Do not accept defragments the disk or backs up files.

Example answers and how they were marked
Full marks2/2

It scans files for malware and quarantines any infected files.

Why: Scans files for malware (1) and quarantines infected files (1).

Some marks1/2

It scans the computer for viruses.

Why: Scanning the computer for malware/viruses (1); no second function.

No marks0/2

It defragments the hard disk so files open more quickly.

Why: Defragmentation is a different utility and does not scan for, quarantine or remove malware; no mark.

2Describe2 marksUtility Software Swap Remove

A hard disk can become fragmented as files are saved and deleted.

Describe how disk defragmentation software improves the performance of a hard disk.

[2 marks]
Mark scheme

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

  • Parts of a file are moved so they are stored together/in consecutive locations (1) so the read/write head has less distance to travel to read the file (1)
  • Files are rearranged so that each file is stored in one block (1) which reduces the time taken to open/load the file (1)
  • Free space on the disk is collected into one area (1) so new files can be saved without becoming fragmented (1)
  • The parts of each fragmented file are put in order (1) so fewer movements of the read/write head are needed to read it (1)

Do not accept responses about compressing files, deleting files or increasing the amount of storage, as these are not what defragmentation software does.

Do not accept 'it makes the disk faster' without saying how the files are changed.

Example answers and how they were marked
Full marks2/2

It moves the parts of a file so they are stored together in consecutive locations, so the read/write head does not have to move as far and the file opens more quickly.

Why: Linked point (1) and development (1): the file parts are stored together, which reduces read/write head movement.

Some marks1/2

It reorganises the files on the hard disk so that they are stored together.

Why: The point is made (1) but there is no development saying how this improves performance, so the second mark is not awarded.

No marks0/2

It compresses the files so that they take up less space on the disk.

Why: This describes data compression software, which the mark scheme says is not accepted; no creditworthy point is made.

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.
