Question

What is the primary role of a router in a network?

Answer 1

The primary role of a router in a network is to direct data packets between different networks. Routers analyze incoming data packets, determine their destination addresses, and use routing tables and protocols to forward these packets to the appropriate next hop or final destination. This function allows multiple networks to communicate with each other, enabling data exchange between devices on separate networks, such as a home network connecting to the internet. Additionally, routers can provide features such as Network Address Translation (NAT), firewall protection, and traffic management to enhance network security and performance.
