Note 2: A data transmission circuit may transfer information in (a) one direction only, (b) either direction but one way at a time, or (c) both directions simultaneously.
Datatransmissioncircuit: The transmission media and the intervening equipment used for the transfer of data between dataterminal equipments (DTEs).
The effective transmission rate is calculated as (a) the measured number of units of data, such as bits, characters, blocks, or frames, transmitted during a significant measurement time interval divided by (b) the measurement time interval.
The effective transmission rate is usually expressed as a number of units of data per unit time, such as bits per second or characters per second.
Transmission through the satellite is much more like transmission through microwave, in microwave information are transmit through the microwave dish antenna where as in satellites transmission, information are transmit through the satellite 500 to 22300 miles in space.
Data is the specific individual facts or the facts, from which decision can be made, it is the raw facts that can be processed in to accurate and relevant information.
Analog transmission is the transmission of a continuously variable signal as opposed to a direct on/off signal.
