1Short recall1 markUtility Software Swap Remove

Backup software is a type of utility software.

State one purpose of backup software.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • To make/keep a copy of files/data (1)
  • To store the copy separately from the original, e.g. on a different device/in a different location (1)
  • So that data can be restored if the original is lost/damaged/corrupted (1)

Do not accept "to save files" on its own, as saving is normal file management and does not make a separate copy.

Do not accept answers that describe a different utility, such as scanning for malware/viruses (anti-malware software).

Example answers and how they were marked
Full marks1/1

To make a copy of data so it can be restored if the original is lost.

Why: Copy of data (1); the restore point is also present but the maximum is one mark.

No marks0/1

To save files to a hard disk.

Why: Saving files is normal file management and does not make a separate copy; the mark scheme says not to accept this, so no mark.

No marks0/1

To scan files for viruses.

Why: Describes anti-malware software, a different utility; the mark scheme says not to accept answers about another utility, so no mark.

2Short recall2 marksUser Management Swap Remove

An operating system sets access rights for each file.

Give two access rights that can be set for a file.

[2 marks]
Mark scheme

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

  • Read/view (1)
  • Write/edit/modify (1)
  • Execute/run (1)
  • Delete (1)

Allow 'read only' for read.

Treat write/edit/modify as one right only.

Do not accept 'open' or 'access' on its own.

Do not accept usernames/passwords (these are authentication, not file access rights).

Example answers and how they were marked
Full marks2/2

Read and write.

Why: Read (1) and write (1) are two separate accepted access rights.

Some marks1/2

Read-only.

Why: Read-only is allowed for read (1), but only one right is given.

No marks0/2

A username and a password.

Why: These are login details used for authentication, not access rights for a file, so no mark is awarded.

3Short 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.

4Explain2 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.
