Understanding Circuit Switching Concepts

What is the first stage in the process of circuit switching?

• Data transfer

• Termination of connection

• Establishing a circuit/channel between sender and receiver

• Error checking

Which of the following is a characteristic of circuit switching?

• It uses a shared channel for multiple transmissions.

• It uses a dedicated channel for a single transmission.

• It is highly flexible and adaptive.

• It does not require a dedicated line.

What happens after the data transfer is complete in circuit switching?

• The connection is terminated.

• The data is stored for future use.

• The circuit is re-established.

• The data is encrypted.

Which of the following is a disadvantage of circuit switching?

• It allows for flexible data transmission.

• It can send empty frames.

• It uses a shared bandwidth.

• It is cost-effective.

In circuit switching, what is the nature of data transmission?

• Unidirectional

• Bidirectional

• Multidirectional

• Asynchronous

What type of data can be transferred using circuit switching?

• Only analogue

• Only digital

• Both analogue and digital

• Only encrypted

Which of the following is a pro of circuit switching?

• It is very flexible.

• The whole of the bandwidth is available for the transmission.

• It allows multiple users to share the same circuit.

• It is suitable for bursty data traffic.

What is the main purpose of circuit switching in a PSTN?

• To provide a dedicated communication line for a phone call.

• To allow multiple calls on the same line.

• To store data for later retrieval.

• To encrypt voice data.

Which of the following is NOT a stage in circuit switching?

• Establishing a circuit

• Data transfer

• Connection termination

• Data encryption

What does circuit switching require for the duration of a connection?

• A shared channel

• A dedicated channel

• A virtual circuit

• A packet-switched network
