Question: What device used in layer 3 to connect multiple networks together?
In networking, a device commonly used in Layer 3 to connect multiple networks together is a "Router." A router is a networking device that operates at the network layer (Layer 3) of the OSI model. It is responsible for forwarding data packets between different networks, making decisions based on IP addresses, and determining the best path for data to travel from the source to the destination across interconnected networks.
Routers use routing tables and protocols to make decisions about where to send data packets. They help route data efficiently and intelligently, ensuring that data reaches its intended destination across complex network topologies. Routers play a crucial role in enabling communication between different subnets, local area networks (LANs), and wide area networks (WANs).
