data transmission
Digital signal transfer
Data transmission is the transfer of information from one point to another, typically through electronic signals over cables, radio waves, or fiber optics.
The term covers everything from a text message to streaming video.
Data transmission can be measured by speed (bandwidth) and reliability: The data transmission failed due to network congestion.
