Switch is a concentrator that has a better traffic management in comparison with the hub.Switches are network devices that work layer of data-link, similar to a bridge, or often referred to as a multiport bridge function to connect multiple LAN segments within a larger network. Compare also with the hub.
Switches have the ability to determine the destination MAC address of the packet. Rather than passing the packet to all ports, switches forward it to the port where he addressed.Thus, the switch can drastically reduce network traffic. Switch maintains a list of MAC addresses that are connected to the port-port which it uses to determine where to send the package. Because it operates on MAC addresses instead of the IP address, the switch is generally faster than a router. currently there are many switches that managable. Besides being able to regulate traffic at the moment there are switches that can also give the IP address.
