Why is packet switching important? Give at least two reasons.
Packet switching is significant due to the following two purposes:
1. A sender and the receiver require coordinating transmission to make sure that data arrives accurately. Dividing the data in small blocks helps a sender and receiver finds that block arrive intact and which one does not.
2. Second, since communication circuits and the connected modem hardware are expansive; multiple computers often share underlying connections and hardware. To make sure that all computers receive fair, prompt access to a shared communication service, a network system permits one computer to deny access to others. By using small packets helps certify fairness.
