Engineering technology deals with the same topics as engineering, but the knowledge is more applied, as opposed to theoretical knowledge. The mathematics and sciences, as well as the technical courses, in technology programs are taught with more application based examples. Engineering courses may also require additional, higher-level mathematics, including multiple semesters of calculus and calculus-based theoretical science courses to prepare students for continued studies and perform research at the graduate level. Engineering technology courses generally have labs associated with the courses that require hands-on applications of the studied topics.

Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines which can be operated without detailed knowledge of their workings.

Technology has many effects. It has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products known as pollution and deplete natural resources to the detriment of Earth's environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics.
