Why is packet switching more efficient then circuit switching?
Circuit switching involves setting up a series of intermediate nodes, in order to propagate the sending node’s data to the receiving node. In such a situation, the communication line can be likened to a dedicated communication pipe. No matter how convoluted the route, that path or circuit stays the same throughout the call. All packets go directly to the receiver in an orderly fashion, one after another on a single path. One call, one circuit. Packet switching involves splitting information into data packets, transmitted separately by intermediate nodes and reassembled when they reach the final recipient. Routers determine a path for each packet “on the fly”, dynamically, ordering them about to use any available path to the destination. Other packets from other calls race upon these circuits as well, making the most use of each track or path, quite unlike the circuit switched calls that occupy a single single path to the exclusion of all others. Upon reaching their destination, the ind
