Which element is necessary for transmitting information between parties in a communication process?

Transmitting information between parties in a communication process fundamentally relies on the presence of a channel. The channel refers to the medium or method through which information flows from the sender to the receiver. This could include various forms of communication, such as verbal communication, written messages, digital platforms, or other means. It plays a crucial role in ensuring that the information is conveyed clearly and effectively to the intended recipient.

Without a proper channel, information cannot be exchanged. For example, if people are trying to communicate but there is no means to send or receive messages—like a breakdown in technology or lack of an established communication method—the communication process would fail. The effectiveness of the communication can also depend on the nature of the channel used, which must be appropriate for the type of information being shared and the characteristics of the audience.

In contrast, while classification, clinical application, and business continuity are important for various aspects of communication and operations in health informatics, they do not directly relate to the fundamental mechanism of transmitting information in the communication process itself. Therefore, the channel is the necessary element that enables the transfer of information in any communication scenario.
