High-level computer programming language whose development was initiated in 1975 by the U.S. Dept. of Defense and standardized in 1983. Ada (named for the countess of Lovelace) was intended to be a common language for use on the department's computers, which were produced by many different manufacturers. It is similar to Pascal but contains many additional features convenient for the development of large-scale, multiplatform programs. The 1995 revision, called Ada 95, supports object-oriented programming.
