The main benefit of using a switch is that it can transmit data faster than a hub. A switch is an important networking device that forwards data packets between the computers attached to the network. The switch has two or more ports, where each port connects to a computer. If one port receives packets faster than it can handle, it will automatically forward them to the other ports so they are not lost. This allows for much quicker transmission of data packets, which means less waiting time for users between pressing send and getting their reply.
