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 markThe Internet Swap Remove

Data packets are sent across the internet.

Name the device that uses IP addresses to forward a data packet from one network to another.

[1 mark]
Mark scheme

Award one mark for:

  • Router (1)

Allow routers (plural).

Allow minor spelling errors that are clearly router, e.g. rooter.

Do not accept switch, hub (these forward data within a network, not between networks), modem or server.

Do not accept gateway on its own.

Example answers and how they were marked
Full marks1/1

Router

Why: Correct device named (1).

No marks0/1

Modem

Why: Modem is not accepted; it is not the device that forwards packets between networks (0).

No marks0/1

Server

Why: A server is not accepted; it does not forward packets between networks (0).

3Short recall1 markImages Swap Remove

A bitmap image uses one bit per pixel.

State the limitation this places on the number of colours in the image.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • Only two different colours can be represented/stored (1)
  • Each pixel can only be one of two values (1)
  • The image can only be shown in black and white (1)

Allow answers that give the number of colours, e.g. two colours, 2 colours

Allow any pair of two colours, e.g. black and white, black and grey

Do not accept low resolution/poor quality/lower quality

Do not accept only one colour/can only show black

Do not accept 2 bits/2^1 without a statement about the number of colours that can be represented

Example answers and how they were marked
Full marks1/1

Only two colours can be represented, such as black and white.

Why: States that only two different colours can be represented (1)

No marks0/1

The image will have a low resolution.

Why: Confuses colour depth with resolution; low resolution is not accepted

No marks0/1

The image can only show black.

Why: One colour is all a single value can give; the limitation is that only two colours can be represented, so this is not accepted
