A switch connects all computer LAN connections into one device like a hub. Unlike hubs, switches can run at full-duplex mode. This means that the computer and switch can both transmit and receive simultaneously. The biggest difference between a switch and a hub is that when a computer transmits a digital signal to a hub, it’s then sent to all ports attached to that hub, whereas a switch will send it only to the specific port where the destination MAC address is located.
