Data is broken into packets and sent across the internet.
Identify the device that forwards a packet towards its destination.
Mark scheme
- B Router (1)
- The only correct answer is B. The correct answer is Router.
- A is not correct because a hub sends the data it receives to every device on the network
- C is not correct because a server provides services, such as web pages, to client computers
- D is not correct because a switch forwards data between the devices on one network
Example answers and how they were marked
Full marks1/1
B Router
Why: Selected the correct device: a router reads the destination IP address in each packet and forwards it towards its destination (1).
No marks0/1
D Switch
Why: A near miss: a switch forwards data between devices on one network, but it is a router that forwards packets between networks towards their destination, so no mark.
No marks0/1
A Hub
Why: Misconception from the examiners' reports: confusing LAN hardware with internet routing. A hub sends data to every device on the network and does not read IP addresses to forward packets, so no mark.
