The difference between routers and switches is that switches connect devices within the same network, while routers connect different networks. Routers are therefore also known as layer 3 devices whereas switches mainly operate at layer 2 (data link layer) of the OSI model. When a device on the LAN needs to communicate outside of its subnet, a switch forwards the traffic to the router that sends the traffic to the appropriate external network. The routing process is used in many scenarios related to computer networking, including: -- A PC communicating with a printer across a Local Area Network, or LAN. +- A PC communicating with a printer located in a different subnet of the same Local Area Network, or LAN. - A phone's web browser communicating with a web server over the Internet. Through routing, these communication signals, called packets, can take multiple paths from the source to the destination.
