Correct answer: A. network layer
- A. network layer
- B. datalink
- C. transport
- D. session
Explanation
Routers work on the network layer (layer 3) of the OSI model. They use IP addresses to route data packets between different networks. Routers maintain routing tables that contain information about the best paths to different destinations. When a router receives a data packet, it examines the destination IP address in the packet header and consults its routing table to determine the best path to send the packet on.
