Switches manage the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended. To review, packet switching works by breaking data up into packets and sending it into a decentralized network; circuit switching works by keeping data along a dedicated line.

A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Networks are made up of various devices—computers, switches, routers—connected together by cables or wireless signals. that have a wired connection to the internet. Switches need to keep track of the MAC addresses of all connected devices.
