Identify the term for the number that identifies a device on a network.
Mark scheme
- B IP address (1)
- The only correct answer is B. The correct answer is IP address.
- A is not correct because a domain name is a name that identifies a website, not the address of a device
- C is not correct because a packet is a small block of data with header information sent across a network
- D is not correct because a sequence number is used to put packets back into the correct order

No marks0/1
D Sequence number
Why: Shows the misconception that any number carried in a packet header, here the one used to reorder packets, is the address of the device; D is not credited.
