Programming Languages - ADA

History

Ada was developed by Jean Ichbiah¹ from 1977 to 1983 to satisfy the exigencies of United States Department of Defense (DoD)² that at current time used a lot of other different programming languages.³

After its revision in early 90s (version called Ada 95) it became the first programming language to be internationally standardized (ISO) as Object-Oriented Language. The language was called like that in honor of Augusta Ada Lovelace⁴, a mathematician who, because of her work with Charles Babbage⁵, is sometimes regarded as the world’s first programmer.

Usage

Ada is principally employed as a language needed in high-integrity, safety-critical or high-security camps including commercial and military aircraft avionics, air traffic control, railroad systems, and medical devices. For example, the fly by wire system software in the Boeing 777 was written in Ada. It is also a quite good teaching purpose language: used worldwide in major universities is proficient at both introductory and advanced computer science courses.⁶
