Why using a router as a network backbone?

Using a router as a network backbone allows for efficient data traffic management and connectivity between different network segments. Routers can intelligently direct data packets based on their destination, optimizing performance and reducing congestion. They also support various protocols and offer features like network security, traffic prioritization, and the ability to connect to multiple types of networks, including WANs and the internet. This versatility makes routers essential for maintaining a robust and scalable network infrastructure.
