What type of network typically involves dedicated channels for communication during each transmission?

A circuit-switched network is characterized by establishing a dedicated communication path or channel between two endpoints for the duration of their communication session. This means that once a connection is established, the entire bandwidth of the dedicated channel is reserved for the duration of the communication, allowing for predictable and consistent data transfer rates.

In contrast, a packet-switched network divides data into packets that are sent separately and can take different routes through the network, meaning that channels are not permanently reserved and bandwidth can vary. A broadcast network allows multiple devices to share the same communication medium, where data is sent to all devices on the network rather than a specific channel. A peer-to-peer network facilitates direct communication between devices without the need for a central server, but it also does not dedicate channels in the same way that circuit-switched networks do.

Thus, the defining feature of a circuit-switched network is its use of dedicated channels, making it the correct answer.
