    A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic, or photovoltaic that converts one type of energy or physical attribute to another for various purposes including measurement or information transfer.
    In telecommunication, the term transponder (short-for Transmitter-responder and sometimes abbreviated to XPDR, XPNDR, TPDR or TP) has the following meanings:
    * An automatic device that receives, amplifies, and retransmits a signal on a different frequency (see also broadcast translator).
    * An automatic device that transmits a predetermined message in response to a predefined received signal.
    * A receiver-transmitter that will generate a reply signal upon proper electronic interrogation.
    A communications satellite?s channels are called transponders, because each is a separate transceiver or repeater.

    Transducer is a device which converts any physical quantity such as temperature,pressure etc into equivalent electric signal.
