1Short recall1 markLANs & WANs Swap Remove

A school's computers are connected in a local area network (LAN). The internet connects computers across the world.

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

[1 mark]
Mark scheme

Award one mark for:

  • WAN/Wide Area Network (1)

Allow wide area network, WAN network, and minor spelling errors where the meaning is clear, e.g. 'wide area netowrk'.

Do not accept LAN/local area network.

Do not accept a description such as 'covers a large area' without naming WAN.

Do not accept 'the internet' or 'world wide web'.

Example answers and how they were marked
Full marks1/1

WAN (wide area network)

Why: Correct type of network (1).

No marks0/1

A network that covers a large area.

Why: Describes a WAN but does not name the type; no mark.

No marks0/1

LAN (local area network)

Why: Names the wrong type of network; the internet is a WAN.

2Explain2 marksAddressing Swap Remove

Routers forward data across the internet.

Explain how a router uses the destination IP address of a packet to send the packet towards its destination.

[2 marks]
Mark scheme

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

  • The router reads/checks the destination (IP) address in the packet (1) so it can forward/send the packet towards that address/destination (1)
  • The router looks up/compares the destination (IP) address (1) to choose the route/next network/next router for the packet (1)
  • The router uses the destination (IP) address to choose/select the outgoing connection/network (1) so the packet is sent one step closer to its destination (1)

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

Do not accept a restatement of the question, such as 'the router uses the IP address to forward the packet', without saying how the address is used, e.g. checking the destination address or choosing the route/next network.

Do not accept answers that say the router gives/adds an IP address to the packet, or that the router uses a MAC address instead of the destination IP address.

Example answers and how they were marked
Full marks2/2

The router checks the destination IP address in the packet and sends the packet out on the route/network that leads towards that address.

Why: Point (1): the router checks the destination IP address; linked reason (1): this is used to send the packet towards that destination.

Some marks1/2

The router checks the destination IP address in the packet.

Why: Point (1): the router checks the destination IP address; no linked reason is given, so only the first mark.

No marks0/2

It adds an IP address to the packet so the packet knows where to go.

Why: Misconception: the router does not add an IP address to the packet; the mark scheme says not to accept this, so no marks.
