Switches and Routers

Are hardware devices used to direct messages across a network, switches create temporary point to point links between two nodes on a network and send all data along that link. Router computers are similar to bridges but have the added advantage of supplying the user with network management utilities. Routers help administer the data flow by such means as redirecting data traffic to various peripheral devices or other computers. In an
Internet work communication, routers not only pass on the data as necessary but also select appropriate routes in the event of possible network malfunctions or excessive use.
