Q.8. What is packet switching? Why is this method used for digital data communication between computers? (2009-10) 

Ans. Packet Switching: It is a digital networking communication method that groups all transmitted data—irrespective of content, type or structure into suitably sized blocks called packets. Packet switching features delivers variable bit rate data streams over a shared network. Packet switching contrasts with other networking method called as circuit switching which is a method which set-up a limited number of dedicated connections of constant bit rate and constant delay between nodes for exclusive use during the communication session.

Two major packet switching modes exist-connectionless packet switching also known as datagram switching and connection oriented packet switching also known as virtual circuit switching. In the first case, each packet includes complete addressing or routing information. The packets are routed individually sometimes resulting in different paths and out of order delivery. In the second case, a connection is defined and preallocated in each involved node before any packet is transferred. The packets include a connection identifier rather than address information and are delivered in order.

Packet mode communication may be utilised with or without intermediate forwarding nodes. In all packet mode communication, network resources are managed by statistical multiplexing or dynamic bandwidth allocation in which a communication channel is effectively divided into an arbitrary number of logical variable bit rate channels or data streams. Each logical stream consists of a sequence of packets which normally are forwarded by the multiplexers and intermediate network nodes asynchronously using first-in, first-out buffering. In packet switching, different messages can pass through different routes and when there is a dead time in the communication between the source and the destination, the lines can be used by other routers.

Packet switching is commonly used for digital data communication between computers because of the following reasons:

1. Packets are short, the communication links between the nodes are only allocated to transferring a single message for a short period of time while transmitting each packet. 

2. Another benefit is pipelining. The total delay for transmission across a packet network may be

considerably less than for message switching.
