Why is routing important?
To determine the optimal route for data to travel, networks employ a system called routing. Network routing examines every possible path that data can take across a network and chooses the route that the data will take. … Routing is important for networks to get data where it needs to go as quickly as possible.
Why do we need routing?
Routing is the hub around which all of IP connectivity revolves. At the simplest level, routing establishes basic internetwork communications, implements an addressing structure that uniquely identifies each device, and organizes individual devices into a hierarchical network structure.
