The Evolution of Computers: A Timeline


In twenty-first century, very few can imagine life without a computer.Now all the operations we carry out are only on the computer. We get scared to think about what it would have to,if we have to write some text on paper and handle it, because we can easily do it on the computer, check out all the mistakes and print it.Now, we had reached on the era of Cloud Computing and 3D Printing. In this section, we would like to tell you about how the computer evolution took place.

Back in the forties, computer can be compared only with some very big device. Just imagine that for a single computer, it required a lot of electronic equipment and a large spacious room. At that time, the very first computers worked only on a very expensive vacuum tubes. Computers were afforded by just big companies and big institutions.

Here are the details of how computer technology evoled in all these years.


1940s 1st GENERATION:




1950: floppy disk from the Tokyo Imperial University Yoshiro Nakamats invention. Its marketing rights obtained by IBM. Created storage era.

1951: Grace Murray Hopper completed a high-level language compiler.

1951: Whirlwind: U.S. Air Force’s first computer-controlled real-time defense system development is completed.

1951: UNIVAC-1: the first commercial computer systems. Designer: J. Presper Eckert and John Mauchly. Used by the U.S. Census Department census, marking computer applications into a new era of commercial applications.
1952: EDVAC (Electronic Discrete Variable Computer): led by the Von Neumann designed and completed. Name: Electronic Discrete Variable Computer.
1953: At this point in the world there are about 100 computers in operation.
1953: core memory is developed.
1954: IBM’s John Backus and his research team began developing FORTRAN (FORmula TRANslation), 1957 years to complete. Is a suitable computer language used in scientific research.
1956: The first conference on artificial intelligence was held at Dartmouth College.
1957: IBM developed the first dot-matrix printers.
1957: FORTRAN successful development of high-level language.

1959: 1959 to 1964 designed computer generally known as the second generation of computers. Extensive use of transistors and printed circuits. Computer volume shrinking function continuously enhanced to run FORTRAN and COBOL, receiving English characters command. A large number of applications.

1959: Grace Murray Hopper began to develop COBOL (COmmon Business-Orientated Language) language, was completed in 1961.

Despite using transistors greatly reduced the size of the computer, reducing its price, reducing the failure. But from the requirements of the people are still far worse, and the various sectors of the computer also had a greater demand, production more stronger, lighter, cheaper machines has become a priority, and the invention of integrated circuits as “timely” when spring is here. Its high degree of integration, not only so that the volume is reduced, but also the speed, fault reduction. People began to manufacture a revolutionary microprocessor. Computer technology after years of accumulation, and finally onto a silicon paved highway.
September 12, 1958: In the Robert Noyce (INTEL company’s founder) under the leadership of the invention of the integrated circuit. And soon launched a microprocessor. But since the invention of the microprocessor is borrowed from Japanese company’s technology, so the Japanese patent does not recognize them, because the Japanese did not receive due benefits. Over 30 years, the Japanese admitted, so Japanese companies can gain a portion of the profits. But in 2001, the patent also fails.




1960: ALGOL: first a structured programming language introduced.
1961: IBM’s Kennth Iverson launched APL programming language.

1971: PASCAL language development is completed.
1972: 1972 after a computer used to be called the fourth generation of computers. Based on LSI and VLSI later. Computers more powerful, smaller. People began to suspect that your computer can continue to shrink, especially heat problems can be resolved? People began to explore the development of fifth generation computers.
1972: C language development is completed. Its main designer was one of the developers of UNIX systems Dennis Ritche. This is a very powerful language development system software, especially loved by others.

1974: The first one has a parallel computer architecture CLIP-4 launch.

Five, computer technology getting into the brilliant. Before this, computer technology mainly in mainframes and minicomputers areas of development, but with the ultra-large scale integrated circuit and microprocessor technology, computer technology into the homes of ordinary people barrier layers have been exceeded. Especially from INTEL released its microprocessors for personal computers after 8080, this will be the surging tide up, but also the emergence of a large number of beach-goers the information age, such as Steve Jobs, Bill Gates, etc., since they are computer industry development also plays an important role. In this period, the Internet technology, multimedia technology has also been an unprecedented development, the computer really started to change people’s lives.

1974 April 1: INTEL released its 8080 8-bit microprocessor chip.
