Which of the following statement is INCORRECT about Circuit Switching ...
Packet-switched describes the type of network in which relatively small units of data called packets are routed through a network based on the destination address contained within each packet. Breaking communication down into packets allows the same data path to be shared among many users in the network.
While in Circuit switching a dedicated communications channel (circuit) between communicating nodes is established through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the channel and remains connected for the duration of the communication session. The circuit functions as if the nodes were physically connected as with an electrical circuit.

Which of the following statement is INCORRECT about Circuit Switching ...
Incorrect Statement: In circuit switching, the data to be transmitted is divided into packets and transmitted through the network independently.
Explanation:
Circuit switching and packet switching are two different methods used in network communication. The incorrect statement in this case is option 'B', which states that in circuit switching, the data to be transmitted is divided into packets and transmitted through the network independently.
What is Circuit Switching?
Circuit switching is a method used in telecommunication networks where a dedicated communication path is established between two endpoints for the duration of the connection. During this connection, a continuous communication channel is provided, ensuring that the bit delay remains constant.
Characteristics of Circuit Switching:
1. Constant Bit Delay: In circuit switching, the bit delay is constant during a connection. This means that once the connection is established, the bits are transmitted continuously without any delay.
2. Efficiency: Circuit switching is considered more efficient than packet switching for certain types of data transmission. It is commonly used for connecting voice circuits, where a continuous stream of data is required.
3. Connection-Oriented: Circuit switching is connection-oriented, meaning that a dedicated path is established before the communication begins. This ensures a reliable and continuous transmission of data.
Packet Switching vs Circuit Switching:
In contrast to circuit switching, packet switching involves dividing the data into smaller packets and transmitting them independently through the network. Each packet can take a different route and may experience different delays before reaching the destination.
Packet switching is commonly used in modern networks, such as the Internet, where data is transmitted in small packets and reassembled at the destination. This method allows for more efficient use of network resources and better scalability.
Conclusion:
In conclusion, the incorrect statement about circuit switching is that the data to be transmitted is divided into packets and transmitted independently through the network. Circuit switching, unlike packet switching, does not involve dividing the data into packets. Instead, it establishes a dedicated communication path and transmits the data in a continuous stream.
