"High tech" and "state of the art" are two expressions that describe very modern technology. High tech is just a shorter way of saying high technology. And high technology describes any invention, system of device that uses the newest ideas or discoveries of science and engineering.

Something that is "state of the art" is the newest possible design or product of a business or industry.
