Which TCP/IP layer is responsible for routing packets between networks?

Explanation:
Routing packets between networks is handled at the Network layer. This layer provides logical addressing with IP addresses and uses routing decisions to move a packet from its source network toward its destination across multiple networks. Routers operate at this level, consulting routing tables and protocols to determine the next hop toward the destination. The Data-Link and Physical layers handle delivery within a single local network segment and the actual transmission over the physical medium, while the Transport layer focuses on end-to-end delivery and reliability between hosts.
