What is the difference between a network switch and a router?

A network switch is a device that connects multiple devices within a local area network (LAN) and allows them to communicate with each other. It operates at the data link layer (Layer 2) of the OSI model and uses MAC addresses to forward data packets to the intended destination device within the same network.

On the other hand, a router is a device that connects multiple networks together, such as LANs or wide area networks (WANs). It operates at the network layer (Layer 3) of the OSI model and uses IP addresses to forward data packets between different networks. Routers determine the best path for data packets to reach their destination by using routing tables and protocols.

In summary, the main difference between a network switch and a router is that a switch connects devices within a single network, while a router connects multiple networks together.
