A routing table has columns for at least three types of information, Network ID, the Cost and The ID of the next Router called Next Hop.
A simple routing table in a computer network is used to determine the best path for data packets to travel from one network device to another. It helps the network devices efficiently route and deliver data to their intended destinations.
In a routing table, a directly connected network is typically indicated by the code "C." This designation signifies that the route is to a network that is directly attached to the router's interfaces. This allows the router to recognize and forward packets to these networks without needing additional routing protocols.

nodes often change their location within network. so, some stale routes are generated in the routing table which leads to unnecessary routing overhead.
