What Does Switch Mean?
A switch, in the context of networking, is a high-speed device that receives incoming data packets and redirects them to their destination on a local area network (LAN).
Techopedia Explains Switch
A switch in an Ethernet-based LAN reads incoming TCP/IP data packets/frames containing destination information as they pass into one or more input ports. The destination information in the packets is used to determine which output ports will be used to send the data on to its intended destination. Again, the thing to remember is that the switch is operating at the data link layer, layer 2, sending a frame that contains a single data packet.
