Which network device is used to connect two different networks and route packets between them?

A router is a networking device that routes data packets between different networks. It operates at the network layer (Layer 3) of the OSI model and uses IP addresses to determine the best path for forwarding packets. Routers are essential for directing traffic on the internet or between various subnets within a local network. Unlike hubs or switches, which operate on the same network, routers are capable of interconnecting multiple networks. Option A (Hub) is incorrect because hubs operate at Layer 1 and simply broadcast data to all connected devices. Option B (Switch) is incorrect as switches work at Layer 2, forwarding data within the same local network segment. Option D (Repeater) is incorrect as repeaters regenerate signals to extend the distance of transmission but do not route traffic between networks. Option E (Bridge) is incorrect; bridges connect two segments of the same network, not different networks.
