Q. How many switching techniques are there? Explain any one.

Answer :-

There are three switching techniques:-

(a) Circuit Switching
(b) Packet Switching
(c) Message Switching

Circuit Switching:- In this technique, first the complete physical connection between two computers is established and then data is transmitted from the source computer to the destination computer. The entire dedicated line is used by the caller and the receiver and no other user can use it even if the line becomes idle. When the data transmission is over, the line is disconnected and is available for the next communication.
