Quizplus · Accepted Answer

Circuit switching involves the establishment of a dedicated physical or logical connection between two devices for the entire duration of the communication session. This connection remains intact even if there is no data being transmitted, and is released only when the session is complete. This type of connection is commonly used in traditional telephone networks where a dedicated circuit is established between two landline phones for the duration of a call.
