1Short recall2 marksUtility Software Swap Remove

Compression software is a type of utility software. A student compresses a large video file before emailing it.

Give two benefits of compressing the video file.

[2 marks]
Mark scheme

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

  • Reduces the file size / uses less storage space (1)
  • Takes less time to upload/download/send (1)
  • Uses less bandwidth / reduces the amount of data transferred (1)
  • The file is more likely to fit within an email attachment size limit (1)
  • Reduces the amount of storage needed for backups / more files can be stored on backup media (1)

Do not award both 'reduces the file size' and 'uses less storage space' as two separate benefits.

Do not award both 'takes less time to send' and 'uses less bandwidth' as two separate benefits.

Do not accept 'it is compressed' on its own.

Do not accept 'it makes the file easier to send' unless a benefit such as a smaller file or less time is given.

Do not accept 'better quality'.

Example answers and how they were marked
Full marks2/2

It uses less storage space and it will upload more quickly.

Why: Uses less storage space (1) and takes less time to upload (1).

Some marks1/2

It reduces the size of the file.

Why: Reduces file size (1); no second distinct benefit.

No marks0/2

The video will have better quality.

Why: Better quality is not a benefit of compression; no mark.

2Short 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.

3Short recall2 marksUser Management Swap Remove

A computer can be shared by more than one user.

Define the term user management.

[2 marks]
Mark scheme

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

  • Manages user accounts/profiles/logins (1)
  • Authenticates users when they log in (through passwords/biometrics) (1)
  • Controls what each user is allowed to access (access rights/permissions) (1)
  • Sets which files/folders/resources a user can use (1)
  • Gives different levels of access to different users (e.g. administrator/standard user) (1)

Allow 'decides which users can use the computer' for the manage user accounts/logins mark.

Allow references to access to files/folders/resources for the access rights mark, as this is part of user management, not file management.

Do not accept 'manages users' on its own.

Do not accept 'controls user access' on its own, as it is unclear whether this means logging in or access rights.

Do not accept 'manages files' or 'manages peripherals' (these are other operating system functions).

Example answers and how they were marked
Full marks2/2

The operating system manages user accounts and logins, and sets access rights so each user can only use certain files and resources.

Why: Manages user accounts/logins (1) and controls what each user is allowed to access through access rights (1).

Some marks1/2

It manages the users who can log in to the computer.

Why: Manages user logins (1); no creditworthy point about access rights/permissions.

No marks0/2

It manages the files and peripherals for different users.

Why: File management and peripheral management are other operating system functions, so neither mark is earned.

4Describe2 marksUtility Software Swap Remove

A student has a large number of photographs stored on a computer.

Describe the purpose of data compression software.

[2 marks]
Mark scheme

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

  • Makes a file/files smaller (1) so less storage space is needed on the disk (1)
  • Reduces the size of the data (1) so it takes less time to upload/download/transfer the file (1)
  • Compresses files/folders into a single file (1) so an attachment is under the size limit for email (1)
  • Reduces the size of the files (1) so more of them fit onto a storage device/backup media (1)

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

Do not accept responses about protecting files from malware/viruses or about deleting files.

Example answers and how they were marked
Full marks2/2

It makes the files smaller so that they use less storage space on the computer and more of them fit on the disk.

Why: The point (1) and a linked development giving the benefit (1).

Some marks1/2

It makes files smaller.

Why: This is the point (1) but there is no development of what the smaller size leads to, so only one mark.

No marks0/2

It protects the files from viruses so that they cannot be damaged.

Why: This describes anti-malware software, which the mark scheme does not accept; no creditworthy point is made.
