Fortran Generation
Its operation is simple, you have two choices, transmit or not transmit. His appearance made the small computers were faster and cheaper. In this generation auxiliary memory is expanded and created the large capacity magnetic disks. Were designed printers and scanners and developed programming languages, are the new programming language called High Level Languages. Third generation 1965-1975 is characterized by the appearance of integrated circuits made in silicon, increasing the speed, the more programs and languages: Cobol, Fortran and the appearance of the terminals to transmit data to the central processor distance, or vice versa. Operating systems appear to control the computer, central warehouses of data that can be accessed from multiple users simultaneously. The first device integrated circuits based entirely on the IBM 360 series also includes an operating system for the control of the machine. A mid-70s are the first minicomputers.
Fourth generation 1975-1990 The most important characteristic of this generation is the emergence of the microprocessor chip, which are circuits with large number of transistors integrated into a small space. Other features include increasing the capacity of data input and output, longer life of components, new programming language Logo, Pascal, Basic, databases. Intelligent terminals arise own memory and word processors. It reduces the size and cost of computers and improves the speed of calculation. Opens a new era with the advent of personal computers or Personal Computer. The first microcomputers were priced more than two million pesetas. In the late '80s, the price was about two hundred thousand pesetas and its yield was 100 times higher.
At this time was the development of operating systems, seeking integration between the user and the computer, through the use of graphics. Fifth-generation 1990-today The revolution arrives with the next-generation microprocessors.
