High technology.

High technology, also known as advanced technology, 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. When high tech gets old, it becomes low tech, for example vacuum tube electronics. Further, high tech is also in contrast to the concept of mid-tech, technology at a level between the two opposite extreme qualities of low-tech and high tech.
