Q. Illustrate about Packet switching?
Packet switching is used to avoid long delays in transmitting data over the network. Packet switching is a technique that limits the amount of data that a computer can transfer on each turn. Packet switching allows many communications to proceed concurrently. Every packet contains a header which specifies computer to which the packet must be delivered and destination is specified using computer's address. Computers which share access to a network take turns in sending packets. On each turn, a given computer transmits one packet. IP uses this packet switching concept to deliver messages on the Internet If destination address doesn't exist on the local network, it's the responsibility of that network's router to route the message one step closer to its destination. This process continues until destination machine claims message packet.
