Routers operate at which layer of the OSI model? physical transport network MAC sublayer of the data link layer session

Answered by admin @ 13/08/2021

Routers operate at the lowest three layers of the OSI network model: the physical layer, data link layer and network layer.

Routers are on the third layer, the Network layer.

They are used to connect networks together. The Internet consists of many interconnected routers. Using a network protocol, like TCP/IP, a router can intelligently move data from one network to another. For example, when a user sends a request for a server, the router in the local network will check its routing table and decide where to resend the data. So, a router needs to have a better understanding of the whole network structure than does a switch. A long distance phone call uses a router like device. The initial one plus area code tells the system that the call is not local but needs to be routed to a distant phone network. The “phone router” then connects the call to the correct distant phone network.
