Which statement best defines technology?

• A. A field of philosophy about technology
• B. The study of machines
• C. A branch of mathematics
• D. The practical application of scientific knowledge, especially in industry

Answer: (D)

Technology is the practical application of scientific knowledge to create tools, processes, and systems that solve real problems and enable production. This means turning ideas from science into usable solutions—devices, software, manufacturing methods, and the organizational know‑how that makes them work in the real world. It’s broader than just machines or abstract study: machines are part of technology, but technology also includes the methods, procedures, and applications that let those ideas function effectively in industry and daily life. The other descriptions point to narrower areas—philosophy about technology, the study of machines, or mathematics—but none capture the full idea of applying science to make useful solutions.
