Which device forwards data between different networks?

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

Answer: (A)

Routing is about forwarding data between different networks. The router is the device that does this by operating at the network layer, using IP addresses and routing tables to decide the next hop for each packet as it travels from one network to another, such as from a home LAN to the internet. This ability to connect multiple networks and determine paths is what enables inter-network communication. Within-network devices like switches and bridges move data inside the same network segment, typically using MAC addresses, so they don’t route between different networks. A modem, on the other hand, handles converting signals for transmission over a link to an ISP and isn’t responsible for directing packets between multiple networks.
