packet switching. n. A method of data transmission in which data is broken into small blocks that are transmitted over different channels and are reassembled into their original order at their destination.
Circuit switching and packet switching are the two switching methods that are used to connect the multiple communicating devices with one another. Circuit Switching was particularly designed for voice communication and it was less suitable for data transmission. So, a better solution evolved for data transmission called Packet switching. The main difference between circuit switching and packet switching is that Circuit Switching is connection oriented whereas, Packet Switching is connectionless. Let us learn some more differences between Circuit Switching and Packet Switching with the help of comparison chart shown below.
