1Short recall2 marksSoftware Basics Swap Remove

Utility software helps to keep a computer system running efficiently.

State two examples of utility software.

[2 marks]
Mark scheme

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

  • File repair (software) (1)
  • Backup (software) (1)
  • Data compression (software) (1)
  • Disk defragmentation (software) (1)
  • Anti-malware (software) (1)

Allow antivirus software.

Do not accept file management, process management, peripheral management or user management, as these are functions of the operating system.

Do not accept operating systems (e.g. Windows, Linux) or application software (e.g. word processor, web browser).

Example answers and how they were marked
Full marks2/2

Anti-malware software and backup software.

Why: Two creditworthy examples from the list, one mark each (1) + (1).

Some marks1/2

Anti-malware software and file management software.

Why: Anti-malware software earns one mark (1); file management is a function of the operating system, so it is not a second mark.

No marks0/2

Windows and a word processor.

Why: Windows is an operating system and a word processor is application software, so neither is utility software and no mark is awarded.

2Short recall2 marksPurpose & Function of Operating Systems Swap Remove

A home computer can have more than one user account.

Name two tasks carried out by the user management function of an operating system.

[2 marks]
Mark scheme

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

  • Creating/deleting user accounts (1)
  • Storing usernames and passwords (1)
  • Checking login details/authenticating a user at login (1)
  • Setting access rights/permissions for each user, e.g. restricting which files/folders/programs/drives they can access (1)

Allow logging in as an example of checking login details.

Do not accept managing users on its own.

Do not accept provides a user interface, as this is not user management.

Do not accept managing files or managing processes, as these are other functions.

Do not accept stopping hackers/protecting from malware, as this is security, not user management.

Example answers and how they were marked
Full marks2/2

It stores usernames and passwords and sets access rights for each user.

Why: Storing usernames and passwords (1) and setting access rights (1) are two different user management tasks.

Some marks1/2

It checks the password at login and manages users.

Why: Checking a password at login earns (1); managing users repeats the question and earns nothing.

No marks0/2

It manages users and stops hackers accessing the computer.

Why: Managing users repeats the question; stopping hackers is security, not user management.

3Describe2 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.

4Explain2 marksPurpose & Function of Operating Systems Swap Remove

A family shares one computer and each person has their own login.

Explain one reason why the operating system needs user management.

[2 marks]
Mark scheme

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

  • The operating system checks usernames/passwords at login (1) so only allowed users can access the computer (1)
  • The operating system stores a list/database of users and passwords (1) so it knows who is allowed to log in (1)
  • The operating system sets access rights/permissions for each user (1) so a user can only open/edit their own files (1)
  • The operating system restricts programs/drives/settings by user (1) so certain users cannot change them (1)
  • The operating system keeps each user's files separate (1) so one user cannot access another user's private files (1)

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

Do not accept 'so the computer is safe/secure' without saying what is protected and from whom.

Do not accept answers that say user management makes the computer faster.

Example answers and how they were marked
Full marks2/2

It sets access rights for each user so each person can only open their own files.

Why: Linked point (1) and reason (1): access rights and file privacy.

Some marks1/2

It checks the username and password at login.

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

No marks0/2

It makes the computer faster because more users can log in.

Why: Misconception: user management is not for improving speed; no creditworthy point.
