Identify the device that uses IP addresses to forward packets from one network to another.

[1 mark]
  • AHub
  • BNetwork interface card
  • CRouter
  • DSwitch
Mark scheme
  • C Router (1)
  • The only correct answer is C. The correct answer is router.
  • A is not correct because a hub sends data to every device on the network
  • B is not correct because a network interface card connects a device to a network
  • D is not correct because a switch forwards data within a single network using MAC addresses
Example answers and how they were marked
Full marks1/1

C Router

Why: Correct option (1): a router uses IP addresses to forward packets between networks.

No marks0/1

D Switch

Why: A switch forwards data within one network using MAC addresses, not between networks (mark scheme line D), so no mark.

No marks0/1

A Hub

Why: A hub only sends data to every device on the network (mark scheme line A), so no mark.

2Short recall2 marksPacket Switching Swap Remove

  • Contains a header with the destination/source IP address (as well as the data) (1)
  • Can be routed/forwarded by routers using the destination IP address (1)

Allow 'unit' on its own for the first mark

Do not accept 'data' on its own

Do not accept a header/destination IP address on its own without identifying a unit/block of data

Do not accept 'a connection/cable between computers'

Do not accept MAC address for the addressing point

Example answers and how they were marked
Full marks2/2

A small unit of data with a header containing the destination IP address.

Why: Unit of data (1) and header with destination IP address (1).

Some marks1/2
