From Wikipedia, the free encyclopedia.
Data transmission is, very generally speaking, the conscious act of moving any kind of information from one space to another. Historically this could be done by courier, a chain of bonfires or semaphores, and later by Morse code over copper wires.
In recent computer terms, it means sending a stream of bits or bytes from one location to another using any number of technologies to do so. Among them are copper wire, optical fibre, radio-link, laser, radio or infra-red light.
A related concept to data transmission is the data transmission protocol used to make the data transfer legible. Current protocols favour packet based communication.
