Chapter 12, Problem 1RQ

To determine

Define packet switching.

Explanation of Solution

Packet switching:

Packet switching is a process by which information is first divided into several parts and then each part is transmitted by a unique digital route. The route of every part is independent of the other depending upon its suitability. All these parts are later re-assembled at final destination.

Packet switching is a way for transmission of data. The importance of packet switching can be explained as follows:

• Packet switching is a cost effective tool as use of different networks does not require massive secondary storage.
• Packet switching ensures reliable communication as parts are re-routed if any problem arises.

The drawbacks of packet switching can be explained as follows:

• Packet switching is a complex process.
• Packet switching requires high implementation cost.
