Which device is specifically designed to forward data packets between computer networks?

• A. Router
• B. Hub
• C. Bridge
• D. Switch

Answer: (A)

The device designed specifically to forward data packets between computer networks is a router. Routers operate at the network layer of the OSI model, making them essential for connecting different networks and directing data traffic effectively. They analyze the destination IP address of incoming data packets and determine the best path for forwarding them towards their destination, which may reside on a different network. Routers are equipped with routing tables and protocols that allow them to communicate with other routers to optimize data delivery, ensuring that packets take the most efficient route. This capability distinguishes routers from devices like hubs, switches, and bridges, which primarily operate within local network contexts or facilitate communication within a single network segment. Understanding the specific role of routers is crucial for managing and designing network infrastructures, as they play a key part in enabling various networks to interconnect and communicate with each other effectively.
