Introduction The invention of the digital computer transformed our civilization during the past 60 years and had profound social, economic and scientific effects. Still humans are just beginning to use the potential of computers. Our future progress will strongly depend on the development of computing technologies, it is important to clearly see the their possibilities. The development of computing technologies depends primarily on the general technological level, available production methods and the market demand for computing.
Computer History: Early electronic digital computation Image 7 – An artistic representation of a Turing machine. A Turing machine is a hypothetical device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer.
Computer History: Second-generation computers Image 13 – IBM 1401. Second-generation computers (1954-1962) - is computers that used transistors. Transistor was invented in 1947. By 1965 second-generation computers were used by many large companies. Image 14 – IBM 7030 Stretch.
Computer History: Third-generation computers Image 15 – IBM System/360 Model 30. 3rd generation of computers (1964-1973) was based on the integrated circuit (computer chip), developed in 1958. First computers of the new generation became available in 1965. Image 16 – IBM System/360 Model 65.
