High technology ( high tech or high-tech ), also known as advanced technology ( advanced tech ) or exotechnology , is technology that is at the cutting edge : the highest form of technology available. It can be defined as either the most complex or the newest technology on the market. The opposite of high tech is low technology , referring to simple, often traditional or mechanical technology; for example, a slide rule is a low-tech calculating device. When high tech becomes old, it becomes low tech, for example vacuum tube electronics. Further, high tech is related to the concept of mid-tech, that is a balance between the two opposite extreme qualities of low-tech and high tech. Mid-tech could be understood as an inclusive middle that combines the efficiency and versatility of digital/automated technology with low-tech's potential for autonomy and resilience.
