What is the term for the movement of information by electromagnetic energy through a transport medium?

The term for the movement of information by electromagnetic energy through a transport medium is transmission. This concept essentially refers to the process of sending data from one point to another via various networks or mediums, including fiber optics, coaxial cables, or wireless communication.

In communication systems, transmission encompasses not just the raw transfer of data but also the techniques and protocols that ensure that the information is correctly interpreted by the receiving end. This term captures the essential element of how signals carry information from the source to the destination, making it fundamental to understanding networking and telecommunications principles.

Propagation, while related, specifically refers to how waves travel through a medium, often focusing on the physical phenomena associated with that movement rather than the conceptual framework of sending information. Conduction typically refers to the transfer of heat or electricity through a medium and is not specific to the movement of information. Transference does not specifically apply to electromagnetic communication or the context of data movement. Thus, transmission is the most appropriate term in this context.
