1Short recall2 marksTopologies Swap Remove

Networks can use different topologies.

Define the term network topology.

[2 marks]
Mark scheme

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

  • The layout/arrangement/structure of a network (1)
  • How devices/nodes are connected together (1)

Allow 'the physical or logical layout/arrangement of a network' for the first point.

Allow 'the way parts of a system/network are connected' for the second point.

Do not award the first mark for 'how devices are connected' on its own.

Do not accept a named topology (e.g. star, bus, mesh) on its own.

Do not accept a network device or how data is transmitted on its own.

Example answers and how they were marked
Full marks2/2

The layout of a network and how the devices in it are connected together.

Why: Layout/arrangement of a network (1) and how devices/nodes are connected together (1).

Some marks1/2

The way devices are connected in a network.

Why: How devices/nodes are connected together (1), but no reference to the layout/arrangement/structure of the network.

No marks0/2

A star network.

Why: Near miss: names a topology but does not define the term.

2Short recall1 markCompression Swap Remove

A company backs up its files to an external hard drive.

Give one reason why the company compresses the files before backing them up.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • More files/data can be stored (in the same storage space) (1)
  • The files take up less storage space (1)
  • The backup is quicker/faster to complete (1)
  • Less data needs to be transferred to the backup device (1)

Do not accept 'makes the files more secure' or 'encrypts the files'.

Example answers and how they were marked
Full marks1/1

The compressed files take up less storage space, so more files can be backed up.

Why: The files take up less storage space (1).

No marks0/1

It reduces the amount of disk fragmentation.

Why: Near-miss: compression does not reduce disk fragmentation.

No marks0/1

It encrypts the files so they are safer if the drive is stolen.

Why: Misconception: compression does not encrypt files, and security is not accepted.

3Describe2 marksUser Management Swap Remove

A school laptop is shared by several teachers.

Describe the purpose of giving each teacher their own user account on the laptop.

[2 marks]
Mark scheme

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

  • Each teacher can keep their own files/desktop separate (1) so other teachers cannot see or change their work (1)
  • Each teacher's work is saved under their own account (1) so they can find their files easily when they log in (1)
  • The operating system knows which teacher is logged in (1) so it can apply the right access rights to that person (1)
  • Each teacher can set up their own desktop/settings (1) so the laptop is set up the way they like to work (1)

Do not accept responses about the laptop running faster or having more storage because it has more accounts.

Do not accept 'so they can log in' without saying why having separate accounts helps.

Example answers and how they were marked
Full marks2/2

Each teacher's files are stored separately, so other teachers cannot open or change their work.

Why: Separate files for each account (1) and other teachers kept out of that work (1).

Some marks1/2

So that each teacher has their own files.

Why: First point of separate files per account (1), but no development of what this achieves (0).

No marks0/2

So the laptop runs faster because each teacher has their own account.

Why: Gives speed as a purpose of user accounts, which is not correct for user management; no creditworthy point.
