Explain about the Switches
LAN switches are an expansion of the method in LAN bridging, which controls data flow, handles transmission errors, gives physical addressing, and manages access to the physical medium. A switch gives these functions by using various link-layer protocols. LAN switches can link four, six, ten or more networks together. A store-and-forward switch, on the other hand, accepts and examines the entire packet before forwarding it to its destination.
Virtual channel is normally a link from one source to one destination, although multicast connections are also allowed. The other name for virtual channel is virtual circuit.
