encoder
encoder
Noun
pl: encoders
This term is primarily used in technical contexts, spanning both software engineering and electrical engineering. In computing, it refers to the process of transforming data into a specific format, often to reduce size or ensure security, which is the inverse of decoding. This usage is common in discussions about video codecs and data transmission.
In mechanical engineering, the term describes a physical sensor used for precision measurement. These devices are critical for feedback loops in robotics and CNC machinery, where they translate physical movement into digital data. Unlike a general sensor, an encoder specifically tracks position or velocity.
