TRANSPONDER Meaning and
Definition
-
A transponder is a device used in telecommunications and electronics that receives and transmits signals. It is a combination of the words "transmitter" and "responder," suggesting its key functions. A transponder typically consists of a transmitter, receiver, and a microprocessor. It is designed to receive a specific signal, process it, and then send a response signal back to the source.
In the field of telecommunications, transponders are commonly used in satellites to receive signals from the ground, amplify them, and retransmit them to specific locations. They act as communication relays, helping to bridge the gap between long distances. Satellite transponders possess different frequency bands, allowing for various types of data transmission like television, telephone calls, and internet signals.
Additionally, transponders are crucial components in transportation systems, especially in aviation and automotive industries. In aviation, transponders are installed on aircraft and communicate with radar systems. They transmit signals containing the aircraft's identification, altitude, and other relevant information for air traffic control purposes. In the automotive industry, transponders are commonly used in keyless entry systems. Small electronic chips embedded within keys send secure signals to a vehicle's receiver, allowing for authentication and remote unlocking.
Overall, transponders play a vital role in the wireless transmission of information and facilitate effective communication between different devices or systems.

Etymology of TRANSPONDER
The word "transponder" is a blend of two different words, "transmitter" and "responder".
"Transmitter" comes from the Latin word "transmittĕre", which means "to send across", formed by combining "trans", meaning "across", and "mittere", meaning "to send".
"Responder" comes from the Latin word "respondēre", which means "to answer", formed by combining "re", meaning "back", and "spondēre", meaning "to pledge or promise".
The term "transponder" was coined to describe a device that receives a signal and sends back a response or reply. It is commonly used in aviation and telecommunications to refer to a radio or radar device that receives a signal, amplifies it, and then transmits a response back to the original sender.
