Questions and Answers

A router operates at the network layer of the OSI model and at the internet layer of the TCP/IP model.

True

Routing is a mechanism that selects a way for data to be transmitted from the source to the destination.

True

A routing algorithm is just a piece of hardware that determines the best path by which a packet may be sent.

False
