Evolution of Computers


Surveys show that recently there has been a considerable increase in the number of people who have a computer at home. Few know about the process of evolution of computers, and travels to modern models of cutting edge technology of today. Following the chronological evolution of computers:


- 1946: it announced the creation of the first electronic digital computer of large-scale world, the ENIAC (Electrical Numerical Integrator and Calculator).
- 1951-1959: there are first-generation computers. They were able to calculate a speed of milliseconds, and they are programmed in machine language.
- 1959 to 1965: emerging second generation of computers, able to calculate a speed of microseconds, being programmed in assembler language.
- 1965-1975: born third generation computers. These computers are replaced by several components miniaturized and mounted onto a single chip, being able to calculate in nanoseconds, with a programming language, high-level oriented procedures.
- 1975-1981: the computers are set up the fourth generation. Following the trend of the third generation of miniaturization of components and improving its Integrated Circuit (IC). The languages used in that generation were very high level, problem-oriented.
- 1990: from that decade are released software with best quality and ability to process information more quickly.
- 2000: after the turn of the millennium the computers continued to follow the trend of miniaturization of their components, thus making the computers more flexible and practical in daily tasks. Moreover, there is a massive investment in its design.

  1. This style of post is not so impressive because the picture is not so clear and nothing we can understand.
