DATA TRANSMISSION?????
Data transmission is the transfer of data to point-to-point often represented as an electromagnetic signal over a physical pointt-to-point or point-to-multipoint communication channel. For example:copper wires, optical fibers, wireless communication channel, and storage media. The term usually refers to digital communication(i.e. degital bit stream) but many include analog data transmission as well.
Data transmission is a subset of the field of data communication, which also includes computer nerworking or computer communication applications and networking protocols.....for example routing and switching.
