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 recall2 marksUser Management Swap Remove

A user must log in before using a computer.

State two methods, other than a password, that an operating system can use to authenticate a user.

[2 marks]
Mark scheme

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

  • Fingerprint scan (1)
  • Face recognition (1)
  • Iris/retina scan (1)
  • Voice recognition (1)
  • Palm print/vein scan (1)
  • Smart card (1)
  • Security token (1)
  • Authenticator app (1)

Allow one-time passcode (OTP) for authenticator app.

Do not accept password (given in the question).

Do not accept username/user ID (it identifies the user but does not authenticate them).

Do not accept 'two-factor authentication' on its own (it is a combination of methods, not a method itself).

Do not accept 'encryption'.

Example answers and how they were marked
Full marks2/2

Fingerprint scan and a smart card.

Why: Fingerprint scan (1) and smart card (1) are two accepted methods.

Some marks1/2

Fingerprint scan and a username.

Why: Fingerprint scan (1); username is not accepted because it does not authenticate the user.

No marks0/2

A username and two-factor authentication.

Why: Username is not accepted because it does not authenticate the user, and two-factor authentication alone is not accepted because it is a combination of methods.

3Explain2 marksPeripheral Management Swap Remove

A new printer is connected to a computer.

Explain the purpose of a device driver.

[2 marks]
Mark scheme

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

  • It allows the operating system/OS to communicate with the device/printer (1) because it translates the commands into signals the device understands (1)
  • It contains/sends the instructions/commands needed by a particular device (1) so the device carries out the correct actions (1)
  • It controls the device/printer (1) by sending commands/signals to it (1)
  • Different devices need different commands (1) so each one needs its own driver to work with the operating system (1)

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

Do not accept 'it drives/controls the device' on its own without saying how, e.g. by sending commands/signals.

Do not accept hardware/a physical device (a device driver is software).

Do not accept 'it connects the printer to the computer' or 'it installs the printer' without saying that it provides the instructions/commands for the device.

Example answers and how they were marked
Full marks2/2

It allows the operating system to send commands to the printer because it translates them into signals that the printer understands.

Why: Linked point (1) and reason (1).

Some marks1/2

It contains the instructions that the printer needs.

Why: Point (1) but no linked reason.

No marks0/2

It is a piece of hardware that connects the printer to the computer.

Why: Misconception: a device driver is software, not hardware, and saying it connects the printer is not accepted without saying it provides the instructions/commands.

4Explain2 marksUser Management Swap Remove

A college computer room has computers that many students share.

Explain one reason why each student has their own user account.

[2 marks]
Mark scheme

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

  • Each student's files/work are kept separate (1) because the operating system checks the access rights of the user who is logged in, so other students cannot open/see/change/delete them (1)
  • A student's own settings/desktop are loaded when they log in (1) because the operating system stores settings for each user account (1)
  • Students cannot install software or change system settings (1) because their user account does not have administrator privileges (1)

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

Award 1 mark for a correct point on its own, even if no linked reason is given.

Allow answers about personal settings/desktop/wallpaper being saved/loaded for that user.

Allow answers about a standard user account not having administrator privileges.

Do not accept 'so they can log in' on its own, because logging in is what the user account is for.

Do not accept 'so they can save files/work' on its own without saying other students cannot access their files.

Do not accept 'so the computer is secure' without saying what is protected or who is kept out.

Do not accept answers about stopping viruses or making the computer run faster.

Example answers and how they were marked
Full marks2/2

Each student has their own account so their files are kept separate from everyone else's. When they log in, the operating system checks their access rights, so another student cannot open or delete their work.

Why: Linked point (1) and reason (1): files/work are kept separate because the operating system checks the logged-in user's access rights, so other students cannot open/change/delete them.

Some marks1/2

Each student's work is kept separate so they can save more files on the computer.

Why: Correct point (1) that work is kept separate, but the reason 'so they can save more files' is not linked to user management/access rights and does not say other students cannot access the files, so no second mark.

No marks0/2

So that the computer does not get a virus from other students.

Why: No credit: stopping viruses is not a reason for separate user accounts, and no user-management point or linked reason is given.
