1Short recall1 markWired Connections Swap Remove

Wired connections have characteristics that affect network performance.

State what is meant by the range of a wired network connection.

[1 mark]
Mark scheme

Award one mark for:

  • The maximum distance data/a signal can be transmitted before it becomes too weak to be received (1)

Allow 'how far a signal can travel'.

Do not accept the number of devices that can be connected to the network.

Do not accept the speed at which data is transmitted.

Do not accept bandwidth/the maximum capacity of a channel.

Do not accept latency/the delay between a signal being sent and received.

Example answers and how they were marked
Full marks1/1

The maximum distance a signal can be transmitted before it becomes too weak to be received.

Why: Gives the maximum distance a signal can be transmitted before it becomes too weak, which is the creditworthy point (1).

No marks0/1

The maximum capacity of the connection.

Why: This describes bandwidth, which the mark scheme says not to accept for range, so no mark.

No marks0/1

The delay between a signal being sent and received.

Why: This describes latency/delay, which the mark scheme says not to accept for range, so no mark.

2Explain2 marksLANs & WANs Swap Remove

A company has a LAN in its head office. It also has a WAN that links the head office to its other offices.

Explain one reason why the WAN costs more to run than the LAN in the head office.

[2 marks]
Mark scheme

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

  • The WAN uses leased lines rented from telecommunications companies (1) so the company pays ongoing rental charges for the connections between its offices (1)
  • The WAN covers a large geographical area (1) so more cabling/equipment must be paid for to connect the sites (1)
  • The WAN connects networks in different locations (1) so more hardware, such as routers, is needed at each site, which adds to purchase and maintenance costs (1)
  • The WAN connects more devices/networks (1) so more money is spent on hardware and management (1)

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

The answer must relate to cost, e.g. paying rental/charges, buying more equipment or paying for maintenance.

Do not accept 'it is bigger' without saying that it covers a larger distance or that more equipment must be paid for.

Do not accept 'it is slower' as a reason for higher cost.

Do not accept 'the WAN is more complex' without expansion as to why this costs more.

Do not accept 'it uses satellites/wireless' unless linked to paying for long-distance infrastructure.

Example answers and how they were marked
Full marks2/2

The WAN uses leased lines rented from a telecommunications company, so the company pays ongoing rental charges for the connections between its offices.

Why: Linked point (1) and reason (1): leased lines are rented, so ongoing rental charges are paid.

Some marks1/2

It covers a larger geographical area, so more equipment is needed.

Why: Earns the first mark for the area point; the reason does not say that the equipment must be paid for, so the cost link is missing.

No marks0/2

It costs more because a WAN is wireless and uses satellites.

Why: No credit: wireless/satellites is not a valid reason and the mark scheme rejects it.
