History of computer

Considering the history of social development, Marxists argue that”history is nothing but a succession of separate generations”. Obviously, this is also true for the history of computers.
Here are some definitions of the term”generation of computers,”taken from 2 sources. ”Generations of computers – is the recent splitting of computers in classes defined element base and performance”. Generations of computers – lax classification of computing systems in the degree of development of hardware and in recent years – the software”. (Dictionary of Computing Systems: Per. From English. Moscow: Mashinostroenie, 1990).
Adoption of the concept of computers belonging to a particular generation and the emergence of the term”Generation”refers to 1964, when the company released a series of IBM computers IBM / 360 of hybrid chips (monolithic integrated circuits at the time had not yet produced in sufficient quantities) , describing the series of third generation computers. Accordingly, previous computers – based on transistors and vacuum tubes – computers second and third generations. Subsequently, this classification, who had come into use, has been expanded and the computers came fourth and fifth generations.
