what is switch in networking

A network switch is a computer networking device (hardware) that joins multiple computers together within one local area network (LAN). Switch works at the Data link layer (layer 2) of the OSI model. A switch does essentially what a hub does but more efficiently. A switch gives a dedicated full bandwidth between every two devices communicating with each other. A switch is more expensive and a network built with switch is faster than one built with hub.
