Which type of data transmission does circuit switching accommodate?

Circuit switching accommodates constant bandwidth for the duration of the call because it establishes a dedicated communication path or circuit between two endpoints for the entire duration of the communication session. This means that once the circuit is established, the bandwidth remains fixed and predetermined, ensuring that both parties have exclusive access to the same set amount of bandwidth throughout the conversation.

This method is commonly used in traditional telephone networks where a dedicated line is maintained for the entirety of a call, thus providing a steady and reliable flow of data. The nature of this type of transmission means that it does not allow for the dynamic allocation of bandwidth, which can lead to variability, as seen in other forms of data transmission that handle data packets independently.
