What is the process of sending and receiving knowledge or intelligence called?

The process of sending and receiving knowledge or intelligence is best described as communication. Communication encompasses the exchange of information through various means such as speaking, writing, gestures, and digital channels. It involves not only the transmission of messages but also the interpretation and understanding of those messages, which is essential for effective interaction between individuals or groups.

While "information" refers to the content or data that is shared, it does not capture the active process of exchanging that content. Options like "data transfer" are more technical and often pertain to the movement of data between systems rather than the broader concept of exchanging knowledge in a more interactive sense. Feedback, on the other hand, is a part of the communication process that refers specifically to the responses received after a message has been sent, but it does not encompass the entirety of sending and receiving knowledge. Therefore, communication is indeed the most accurate term that describes the overall process of exchanging knowledge and intelligence.
