What is a Network Switch?
A network switch is network hardware that connects devices for the purpose of sharing business resources. Devices connect to a network switch, usually through Ethernet cables, in order to communicate more directly with other devices in the network.
When one device communicates with another device in the network, the message is broken down into packets that are sent along cables connecting to a port on the network switch. The network switch then reads the intended destination for the packet and forwards it through the ports that connect to the receiving device.
Network switches play an important role in connecting the devices of an organisation’s Local Area Network (LAN).
