I. Introduction
Computer science, not only gives a great impact on the development of productive forces as a kind of material progress, but also exercises a great influence on the development of people's ideology as a sort of intellectual progress. People who are devoted to study and pursuit of science should attach importance to the achievements made in the study of computer science history not only from the point of productive forces but from the point of ideology, and give a full play of its cultural function and spiritual value of computer science history. The birth, evolution and development of computer science theories condenses the scientists' method of thinking and research, which is more valuable than the specific knowledge.
