1950

The 1950s were a pivotal period in the history of computer science, witnessing a significant shift from theoretical research to practical applications in computer technology. This section offers a comprehensive overview of computer science in the 1950s from various aspects including research focus, key events, important milestones, and main figures.

I. Research Focus

  1. Hardware Development and Computer Architecture:
  2. Rise of Electronic Computers: In the 1950s, electronic computers began to replace mechanical and vacuum tube computers, becoming mainstream. The invention and application of transistors provided the technical foundation for miniaturization and enhanced reliability of computers.
  3. Memory and Storage Technologies: New storage technologies such as magnetic drums, tapes, and core memory were gradually applied, improving data storage and access speeds of computers.

  4. Computer Architecture Design: The von Neumann architecture became dominant, proposing the concept of stored program, where programs and data are stored in the same memory. This idea profoundly influenced subsequent computer designs.

  5. Software Development and Programming Languages:

  6. Birth of Programming Languages: With the increasing complexity of computer hardware, the demand for efficient programming drove the development of high-level programming languages. In 1957, Fortran (Formula Translation) was introduced by IBM and became the first widely used high-level programming language, greatly enhancing programming efficiency and maintainability.

  7. Initial Development of Operating Systems: Although operating systems were not yet mature, some basic batch processing systems began to appear, aiming to optimize the use of computing resources and improve calculation efficiency.

  8. Theoretical Research and Algorithms:

  9. Algorithms and Computation Theory: As a burgeoning discipline, theoretical research in computer science began to unfold. Foundational theories such as the Turing machine model and computational complexity theory were gradually established, providing theoretical support for subsequent algorithm design and computational models.

  10. Emergence of Artificial Intelligence: The Dartmouth Conference in 1956 marked the birth of artificial intelligence as an independent research field, initiating the exploration of simulating intelligent behavior with computers.

  11. Expansion of Application Areas:

  12. Scientific Calculation and Engineering Applications: The application of computers in scientific research, engineering design, weather forecasting, etc., gradually unraveled, solving numerous complex computational problems.
  13. Business and Management: Large enterprises such as banks and insurance companies began using computers for data processing and business management, improving operational efficiency.

II. Key Events and Milestones

  1. Introduction and Promotion of Electronic Computers:
  2. UNIVAC I (1951): Developed by the cooperation of General Electric Company (GE) and the University of Pennsylvania, it became the world's first commercial electronic computer. The successful sale of UNIVAC I marked the entry of computers into the commercial application stage.

  3. IBM 701 (1952): IBM launched its first commercial electronic computer, mainly targeting the scientific and engineering computing market, laying the foundation for IBM's leadership in the computer market.

  4. Emergence of Programming Languages:

  6. LISP (1958): Developed by John McCarthy, LISP became the main programming language for artificial intelligence research, advancing the AI field.

  7. Dartmouth Conference (1956):

  8. Considered as the birthmark of the AI field, the conference was organized by John McCarthy, Marvin Minsky, and others, introducing the term "artificial intelligence" and laying the foundation for AI research.

  9. Emergence of Transistor Computers:

  10. Transistors replaced vacuum tubes as the new trend in computer hardware, enhancing the reliability and efficiency of computers. For instance, the TRADIC (Transistorized Air Defense Calculator) was put to use in 1955 as the world's first transistor computer.

  11. Advances in Memory Technology:

  12. Core Memory: The invention of core memory in the mid-1950s greatly improved computer storage capacity and access speed, becoming the mainstream RAM technology.

III. Important Figures
