Answer 2

Circuit switching is a technique in which a dedicated and complete ‘physical connection’ is established between ‘two nodes for communication’.

Answer: Option B

Explanation:

The circuit switching is represented as a method of implementing tele-communication network, where 2 networks generate a communication path or dedicated communication circuit via the provided network before the communication happens between the nodes.  

This communicated channel will have channel with full band width and remained to be connected for the time duration of the communicated sessions. Here the nodes were connected physically with an electric circuit. One of the examples are previously used analog phone network.
