Transponder

A transponder is a specialized communication device that receives a signal and automatically transmits a response. It is widely used in various applications, including aviation, satellite communications, and vehicle tracking. In aviation, transponders play a crucial role in air traffic control by responding to radar signals, thus helping to identify aircraft. These devices enhance safety and efficiency in air travel. Transponders also help in international communication systems, making them essential for modern technology.

Transponder meaning with examples
