Data transmission
From Free net encyclopedia
Data transmission is the conveyance of 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, such as copper wire, optical fibre, laser, radio or infra-red light. Practical examples include moving data from one storage device to another and accessing a website, which involves data transfer from web servers to a user's browser.
A related concept to data transmission is the data transmission protocol used to make the data transfer legible. Current protocols favour packet based communication.
