What is circuit switching, and what are its chief characteristics?

What will be an ideal response?

The term circuit switching refers to a communication mechanism that establishes a path
between a sender and receiver with guaranteed isolation from paths used by other pairs of senders
and receivers. Circuit switching is usually associated with telephone technology because a telephone
system provides a dedicated connection between two telephones. The circuit switching has the
following main characteristics:
? Point-to-point communication
? Separate steps for circuit creation, use, and termination
? Performance equivalent to an isolated physical path
