Abstract: The philosophical meanings of information technology (IT) have derived from its daily usages but they are not completely equivalent in that IT in the sense of “modern technology” includes the traditional IT as well. From the philosophical meanings of “technology”， we can safely conclude that IT not only includes the implement information technology， but also the body information technology. And from the philosophical meanings of “information”， it can be confirmed that IT is different from the mass-energy production technologies and the implement information technology in the strict sense is merely “signal technology”. It is the body information technology that makes the real information technology.

Key words: information technology, body, implement
