Describe a router.
What will be an ideal response?
A router is a special-purpose device designed to interconnect networks. For example, three different networks can be connected using two routers. If a computer in network A needs to send a packet of information to network C, both routers pass the packet from the source network to the destination network. Routers maintain routing tables in their memories to store information about the physical connections on the network. The router examines each packet of data, checks the routing table, and then forwards the packet if necessary. Every other router in the path (between a source and a destination network) performs a similar procedure. Note that a router does not maintain any state information about the packets; it simply moves them along the network. Routers operate at layer 3 (Network) of the OSI model.
