A ___________ is a network device that forwards data packets between computer networks.
- Hub
- Modem
- Router
- Switch
A router is a network device that forwards data packets between computer networks. Routers operate at the network layer (Layer 3) of the OSI model and use routing tables to determine the best path for forwarding packets. Hubs and switches operate at lower layers and have different functionalities within a network, such as connecting devices in the case of hubs or creating separate collision domains in the case of switches. A modem, while essential for connecting to the internet, does not perform the same packet-forwarding function as a router.
