Which device provides a point of connection between two or more networks and forwards packets between networks?

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

Answer: (B)

Routing connects multiple networks and forwards packets between them. A router operates at the network layer, using destination IP addresses and routing tables to select the best path and send each packet toward its destination network. This capability enables inter-network communication, such as linking your local network to the Internet. Other devices don’t perform this cross-network routing: a bridge or switch handles frame forwarding within the same local network (layer 2), a hub simply repeats signals to all ports with no traffic control, and a modem connects to an Internet service provider by translating signals, not routing between internal networks.
