Cumputer Historial.

Computer History.
The computer is a recent invention , which has not met even one hundred years of existence since its first generation. However it is an invention that has revolutionized the way we work , entertain and has become an essential instrument in our daily lives .
And now, continuing with the history of the computer :

First Generation ( 1951-1958 ): The first generation computers used bulbs to process information. Operators entering data and programs in special code by punched cards. The internal storage was accomplished by rapidly spinning drum , on which a read / write magnetic marks placed . Those computers were much larger bulbs and generated more heat than contemporary models.
Second Generation (1959-1964): Transistor Limited Compatibility :
The invention of the transistor made ​​possible a new generation of computers , faster , smaller and less need for ventilation. Computers of the second generation networks also magnetic cores used instead of rotating drums for primary storage . These nuclei contained small rings of magnetic material, linked together , which could be stored in data and instructions .
The 2nd Generation computers were substantially smaller and faster than bulbs , and were used for new applications such as reservation systems for airlines, air traffic control and simulation for general use.
Third Generation (1964-1971)

Integrated Circuits , Equipment Support Staff, multiprogramming , Minicomputer :

The computers of the third generation emerged with the development of integrated 

circuits ( silicon wafers ) in which thousands of electronic components are placed in

 a miniature integration . Computers again became smaller , faster, they gave off 

less heat and were more energy.

The computers worked so fast that provided the ability to run more than one program

 simultaneously ( multiprogramming ) 

Fourth Generation (1971 -present)

Microprocessor, memory chips , microminiaturization :


Two improvements in computer technology marks the beginning of the fourth 

generation : the replacement of the memories with magnetic cores, the silicon chip

 and the placement of many more components on a chip : product microminiaturizatio

n electronic circuits . The small size of the microprocessor chip made ​​possible 

the creation of personal computers ( PC Personal Computer) .
