Information: - In computing, source code is any collection of computer instructions, possibly with comments, written using a human-readable programming language, usually as ordinary text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code understood by the computer. The machine code might then be stored for execution at a later time. Alternatively, source code may be interpreted and thus immediately executed. - Jean David Ichbiah ( 25 March 1940 -- 26 January 2007 ) was a French computer scientist and the initial chief designer ( from 1977 -- 1983 ) of Ada , a general - purpose , strongly typed programming language with certified validated compilers . At the time , he was a member of the Programming Research division at CII Honeywell Bull ( CII - HB ) in Louveciennes , France . He had previously designed an experimental system implementation language called LIS ( 1972 -- 1974 ) , based on Pascal and Simula ( in fact , he had been chairman of the Simula User 's Group ) , and was one of the founding members of IFIP WG 2.4 on Systems Implementation Languages . Ichbiah 's team submitted the language design labelled '' Green '' to the competition to choose the United States Department of Defense 's embedded programming language . When Green was selected in 1978 , he continued as chief designer of the language , named '' Ada '' . In 1980 , Ichbiah left CII - HB and founded the Alsys corporation in La Celle - Saint - Cloud , which continued language definition to standardize Ada 83 , and later went into the Ada compiler business , also supplying special validated compiler systems to NASA , the US Army , and others . He later moved to the Waltham , Massachusetts subsidiary of Alsys . Ichbiah designed the keyboard layout FITALY which is specifically optimized for stylus or touch - based input , and subsequently started the Textware company , which sells text entry software for PDAs and tablet PCs , as well as text - entry software for medical transcription on PCs. In 1979 , Jean Ichbiah was designated a '' chevalier '' ( knight ) of the French Legion of Honour and a '' correspondent '' of the French Academy of Sciences . He received a Certificate of Distinguished Service from the DoD for his work on Ada . He was a descendent of Greek and Turkish Jews from Thessaloniki who emigrated to France . Jean Ichbiah died from complications of a brain tumor on January 26 , 2007 . - A programming language is a formal computer language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms. - A compiler is a computer program (or a set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language), with the latter often having a binary form known as object code. The most common reason for converting source code is to create an executable program. - Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems. - A computer scientist is a scientist who has acquired the knowledge of computer science, the study of the theoretical foundations of information and computation and their application. - Object code, or sometimes an object module, is what a computer compiler produces. In a general sense object code is a sequence of statements or instructions in a computer language, usually a machine code language (i.e., binary) or an intermediate language such as Register transfer language.
