Answer 2

Circuit Switching:

Circuit switching is defined as a mechanism applied in telecommunications whereby the user is allocated the full use of the communication channel for the duration of the call. That is if two parties wish to communicate, the calling party has to first dial the numbers of the called party. Once those numbers are dialed, the originating exchange will find a path to the terminating exchange, which will in turn find the called party.

Advantages of Circuit Switching:

• Once the circuit has been set up, communication is fast and without error.
• It is highly reliable

Disadvantages of Circuit Switching:

• Involves a lot of overhead, during channel set up.
• Waists a lot of bandwidth, especial in speech whereby a user is sometimes listening, and not talking.
• Channel set up may take longer.
