Circuit and Packet Switching Quiz

What is the first stage in circuit switching?

• Data transfer begins

• A circuit/channel is established between sender and receiver

• The connection is terminated

• Packets are routed independently

Which type of communication line does circuit switching use?

• Shared channel

• Dedicated channel

• Broadcast channel

• Multicast channel

During data transfer in circuit switching, the transmission is typically:

• Unidirectional

• Bi-directional

• Half-duplex

• Multicast

Which of the following is an advantage of circuit switching?

• More efficient use of bandwidth

• Consistent quality of service

• Better for bursty data traffic

• Lower setup time

Which of the following is a disadvantage of circuit switching?

• Communication line is tied up during the entire connection

• Data packets can be lost

• Less secure compared to packet switching

• Difficult to implement

Circuit switching is most commonly used in:

• Traditional telephone networks (PSTN)

• Email systems

• Internet browsing

• File sharing networks

In circuit switching, when is the communication channel released?

• As soon as the connection is established

• After the data transfer is complete and the connection is terminated

• During data transfer

• It remains active indefinitely

What type of data can be transferred using circuit switching?

• Only digital data

• Only analogue data

• Both analogue and digital data

• Neither analogue nor digital data

In circuit switching, if the connection is interrupted during data transfer, what happens?

• The data is saved for later transfer

• The connection is lost, and data must be re-sent

• The data automatically reroutes

• The connection automatically reestablishes

Which of the following best describes circuit switching?

• Data is sent in packets over multiple routes

• A continuous path is established for data transfer

• Data is broadcast to all nodes in the network

• Only error-free data is transmitted
