What is a network switch, and how does it work?

WebRouters figure out the fastest data path between devices connected on a network, and then send data along these paths. To do this, routers use what's called a "metric value," or preference number. If a router has the choice of two routes to the same location, it will choose the path with the lowest metric. The metrics are stored in a routing table. WebWhat the network needed was a more logical device that could make decisions for where to send data and block the traffic flow to irrelevant devices. The switch accomplishes these requirements by executing four basic functions: Learning, Forwarding, Filtering and Flooding. These functions are present in a switch by default, right out of the box. citb levy hmrc
