Question 9

How does packet switching work?

Accepted Answer

Packet switching is a method of slicing digital messages into parcels called packets,sending the packets along different communication paths as they become available,and then reassembling the packets once they arrive at their destinations.Packet switching makes much more efficient use of the communications capacity of a network than did circuit-switching.In packet-switched networks,messages are first broken down into small fixed bundles of data called packets.The packets include information for directing the packet to the right address and for checking transmission errors along with the data.The packets are transmitted over various communications channels using routers,each packet traveling independently.Packets of data originating at one source will be routed through many different paths and networks before being reassembled into the original message when they reach their destinations.
