Ada is a computer programming language. It is very similar to the programming language Pascal. Ada offers various features to make a programme as safe as possible. That is why it is often used in systems, where an error can be very dangerous. Ada is an international standard. Ada was originally designed by a team led by Jean Ichbiah under contract to the United States Department of Defense (DoD) from 1977 to 1983 to supersede over 450 programming languages used by the DoD at that time. Ada was named after Ada Lovelace (1815–1852), who has been credited with being the first computer programmer.
