1Multiple choice1 markLANs & WANs Swap Remove

Networks can be classified by the area they cover.

Identify the type of network that the internet is an example of.

[1 mark]
  • ALAN
  • BMAN
  • CPAN
  • DWAN
Mark scheme
  • D WAN (1)
  • The only correct answer is D. The correct answer is WAN (wide area network).
  • A is not correct because a LAN covers a small geographical area, such as one building
  • B is not correct because a MAN covers a city or large town
  • C is not correct because a PAN connects devices around one person, such as with Bluetooth
Example answers and how they were marked
Full marks1/1

D WAN

Why: Correct option: the internet is the largest example of a WAN (1).

No marks0/1

B MAN

Why: Near-miss: a MAN covers a city or large town, not networks all over the world, so the mark scheme gives it 0.

No marks0/1

A LAN

Why: Misconception: the candidate treats the internet as a LAN because their home network is a LAN; the mark scheme says a LAN covers a small geographical area, so 0.

2Short recall1 markTopologies Swap Remove

A bus topology uses terminators at each end of the main cable.

State the purpose of terminators in a bus topology.

[1 mark]
Mark scheme

Award one mark for:

  • Absorb signals (at the ends of the bus cable) / prevent signals reflecting (back along the cable) (1)

Allow 'stop data/signals bouncing back' for prevent signals reflecting

Do not accept 'terminate the cable' / 'close the end of the cable' on its own

Do not accept boost/repeat/strengthen the signal

Example answers and how they were marked
Full marks1/1

To absorb signals so that they do not reflect back along the bus cable.

Why: Absorbing signals and preventing reflection are alternatives within the one creditworthy point (1).

No marks0/1

To terminate the cable at each end.

Why: Near miss: this is rejected by the 'terminate the cable' guidance because it does not say signals are absorbed or prevented from reflecting.

No marks0/1

To make the signal stronger at the end of the cable.

Why: Misconception: terminators absorb signals; they do not boost, repeat or strengthen them.

3Convert1 markBinary to Denary Conversion Swap Remove

Computers manipulate binary patterns.

Convert the binary pattern 1010 0100 to denary.

[1 mark]
Mark scheme

Award one mark for:

  • 164 (1)
Example answers and how they were marked
Full marks1/1

164

Why: Correct: 128 + 32 + 4 = 164 (1).

No marks0/1

37

Why: Reads the place values from the wrong end (the left-hand bit as 1), so the value is wrong.

No marks0/1

3

Why: Counts the 1s instead of adding their place values.
