Why routing is important in computer network

Routers perform two basic and important functions first they choose a proper path in given networks, and secondly, they transmit information packets by that path to the desired destination.  While doing so they draw on routing protocols and algorithms. With the help of these algorithms, plot routes are designed. Tables of conditions and availably of routes are created so that router can choose the most efficient path for each and every transmission.  

When a router received a packet and opens it, router check its network destination address and calculates the next hop in the lowest-cost, route to the destination. A hop is measured through the passage of a packet from a router.
