Overview
A key idea in computer networking, routing allows networks to communicate with one another. It involves choosing the most efficient route for data packets to take in order to get from a source device to a destination device. Routing guarantees effective, safe, and dependable data transfer across local networks, corporate infrastructures, and the internet in contemporary networks.
The process by which routers choose the best route for packet forwarding is known as routing. To determine where the packet should be sent next, a router examines the destination IP address and refers to its routing database. Until the packet arrives at its destination, this process keeps going hop after hop.
Real-Life Example
Think about shipping a package from one city to other city. The courier service chooses the quickest and most effective route out of those that are accessible. An alternate path is selected when a road is closed. In a similar way, routers select the optimal data transmission path either statically or dynamically.
