1Short 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.

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.

3Describe2 marksPeripheral Management Swap Remove

A computer is connected to a new games controller.

Describe the purpose of a device driver.

[2 marks]
Mark scheme

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

  • A device driver is software/program (1) that controls a peripheral device (1)
  • It translates instructions from the operating system (1) into commands/signals the device understands (1)
  • It allows the operating system to communicate with a specific device (1) without needing to know the device's hardware details (1)
  • It is installed for a new device (1) so the operating system can use that device (1)

Do not accept responses that say a device driver is hardware or that it makes a device faster.

Do not award 'it is part of the CPU'.

Example answers and how they were marked
Full marks2/2

A device driver is a program that controls a peripheral device. It translates instructions from the operating system into commands the device understands.

Why: Gives the linked description: software/program (1) that controls a peripheral (1).

Some marks1/2

It translates instructions from the operating system.

Why: Gives the first point (1) but does not develop it into commands/signals the device understands.

No marks0/2

A device driver is a piece of hardware that connects the controller to the computer.

Why: No credit: says a device driver is hardware, which the mark scheme does not accept.
