Q: Which tier of the five-layer TCP/IP paradigm does a router run on?
- The transport layer
- The network layer
- The data link layer
- The application layer
Explanation: Routers function at the third level of the TCP/IP five-layer paradigm, which is referred to as the Network layer. The Network layer is in charge of logical addressing, routing, and the transmission of data packets across the various networks. It also handles the forwarding of data packets. Routers make judgments based on IP addresses to identify the next hop for a packet as it makes its way from the source to the destination across several networks.
