Routers work in layers two, three, and four
layer 1 Physical (copper, fiber,...)
layer 2 Datalink (ethernet, token ring, ...)
2->3 providing address resolution (ARP) ie. media access control (MAC) to IP translation
layer 3 Network (IP,IPX,RIP,...)
3->4 providing routing
layer 4 Transport provides error handling in connectin oriented delivery and handles connectionless delivery Conneciton Oriented(TCP,SPX) Connectionless (UDP)
What else can I help you with?
Which layer of osi model has the important role of providing error checking?
Data link Layer
What layer of the OSI model is Voice over IP located?
transport
Which layer of the OSI model is primarily concerned with accessing the physical media and physical addressing?
Data Link
What differences between TCP and IP?
tcp is the transport control protocol and ip is the internet protocol. tcp is concerned with guaranteed delivery of packets from source to destination, while ip is the protocol used to actually deliver packets. tcp is located at layer 4 of the osi model, or the transport layer. ip is located at layer 3 of the osi model, or the network layer. check out the video tutorials in the link below.
