1Multiple choice1 markLANs & WANs Swap Remove

A supermarket chain has stores in several countries. Each store has its own network.

Identify the type of network that connects the stores in the different countries.

[1 mark]
  • ALAN
  • BPAN
  • CWAN
  • DWLAN
Mark scheme
  • C WAN (1)
  • The only correct answer is C. The correct answer is WAN, which connects networks over a large geographical area.
  • A is not correct because a LAN covers a limited area such as one building or site
  • B is not correct because a PAN connects devices around one person
  • D is not correct because a WLAN is a LAN that uses wireless connections and is still local
Example answers and how they were marked
Full marks1/1

C WAN

Why: Correct option: a WAN connects networks over a large geographical area (1).

No marks0/1

A LAN

Why: Distractor, not a partial-credit answer: each store may have its own LAN, but the network linking stores in different countries is a WAN (0).

No marks0/1

D WLAN

Why: A WLAN is still a local-area network that uses wireless connections and cannot connect stores in different countries (0).

2Short recall2 marksWired Connections Swap Remove

A company can choose between two wired connections. Connection B has a higher bandwidth than connection A.

Give two benefits to the company of choosing connection B.

[2 marks]
Mark scheme

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

  • Files/data download/upload more quickly (1)
  • More employees can use the connection at the same time without it slowing down (1)
  • Web pages/streamed video load more quickly with less buffering (1)
  • Video calls/conferencing run at a higher quality (1)
  • Updates/backups can be completed in less time (1)

Allow 'multiple users' or 'more devices' for the shared-use point

Allow 'video streams more quickly' or 'less buffering' on their own

Do not accept lower latency, as a higher bandwidth does not reduce latency

Do not accept 'more data can be transferred per second' or 'a bigger bandwidth', as these repeat what bandwidth is

Do not accept 'more reliable' on its own, as a higher bandwidth does not make a wired connection more reliable

Example answers and how they were marked
Full marks2/2

Files will download more quickly, and more employees can use the internet at the same time without the connection slowing down.

Why: Files download more quickly (1) and more users without slowdown (1).

Some marks1/2

Web pages will load faster and the connection will have a longer range.

Why: Web pages load faster (1); the range of a connection is not increased by bandwidth, so that point is not credited.

No marks0/2

The connection will be more reliable because it has a bigger bandwidth.

Why: 'More reliable' is not credited on its own and 'bigger bandwidth' repeats the question, so no marks.

3Short recall1 markWireless Connections Swap Remove

A wireless network has a fixed amount of bandwidth.

State what happens to the bandwidth available to each device as more devices connect to the network.

[1 mark]
Mark scheme

Award one mark for:

  • It is shared between more devices, so each device gets less (bandwidth) (1)

Allow 'the bandwidth is divided/split between the devices'.

Allow 'there is less bandwidth for each device'.

Do not accept 'the speed decreases' / 'the connection slows down' on its own.

Do not accept 'the bandwidth decreases' unless it refers to the bandwidth available to each device.

Do not accept 'the bandwidth increases'.

Example answers and how they were marked
Full marks1/1

It is shared between more devices, so each device gets less bandwidth.

Why: States that the bandwidth is shared between more devices and so each device gets less (1).

No marks0/1

The speed for each device decreases.

Why: Describes speed rather than bandwidth; this near-miss is ruled out by the 'Do not accept' line.

No marks0/1

The bandwidth increases because more devices are connected.

Why: Contradicts the correct answer; bandwidth is shared between the devices, it does not increase, so no mark.
