Engineering is the application of scientific, economic, social, and practical knowledge in order to invent, design, build, maintain, research, and improve structures, machines, devices, systems, materials and processes. An engineering technologist is a specialist dedicated to the development, design, and implementation of engineering and technology. Engineering technology education is more of a broad specialized and applied engineering discipline than the generalized and theoretical engineering degree education. The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.
