A network switch, also known as the switching hub, refers to the networking hardware essential for connecting devices. It is responsible for forwarding data packets to and from the connected devices. Unlike the routers, here, only a switch sends the data to another switch or single device instead of the networks of multiple ones. Mostly, the switches use ethernet for transferring the data among the devices. These are essential for seamless communication between multiple networked machines. It also helps manage the data flow across the network by transmitting the data packets.
