Data Transmission Data transmission is the process of conveying data between two points by way of a communication medium .
Bounded media confine the data to specific physical pathways.
Common examples of bounded media are wire and optical fiber cables. Cable TV uses bounded media. Unbounded media transmit the data-carrying signal through space, independent of a cable. Broadcast radio and television are examples of unbounded media. When practical, cable represents a low-cost and reliable means of transmitting data between computing devices.
