This would include any content requiring a computer program to process it at the other end. For example, financial institutions often transmit raw data and computers interpret the data at the other end. What they are doing is confusing directionality with simultaneity. All communication is either simultaneous or non-simultaneous. This attribute is not a continuum from simultaneity to non-simultaneity.

The two primary types of conduit are wired are wireless. Wired transmissions travel over copper wire, coaxial cable, or fiber optic cable. Wireless transmissions use a particular frequency and bandwidth within the electromagnetic spectrum, or, in the case of sound waves, vibrations in the atmosphere.
