Computer Revolution (S.O).

The first computers of the 1940s had only two levels of programming language: the level of machine language, in which all programming was done, and the level of digital logic, where the programs were effectively implemented.


Computer (1940)

With Wilkes in 1951, the idea of designing a computer at three levels, in order to simplify the hardware. This machine had a program called interpreter stored permanently, whose function was to run the programs into machine language.

Computer (1961)

The hardware could be simplified thus: would just run a small set of microinstructions stored instead of the entire program into machine language, requiring fewer electronic circuits. From then begin to evolve the languages ​​and the architectures of the machines, driven mainly by the emergence of a new concept in the History of Computing: Operating Systems.
