ORIGIN AND EVOLUTION OF

COMPUTERS

1º Bach A Alejandro Moreno Castro

ORIGIN OF COMPUTERS-The first antecedent is considered a calculating machine invented

in 1642 by Pascal.

-In the 18th century, Joseph-Marie Jacquard created the punch

cards.

-In 1822, Charles Babbage created the Difference engine, and eleven years later, he designed the analytical engine.

-In 1932, Vannevar Bush created the Differential analyser

FIRST GENERATION (1945-1958)

1945: John Eckert and John Mauchly crated the first computer with

Vacuum tuve called ENIAC.

1949: Maurice Wilkes created the EDSAC.

1950: Echerk and Mauchly crated the first electric

computer of management, the UNIVAC.

SECOND GENERATION (1959-1965)

-The second generation of computers appeared with the replacement

of vacuum tubes by transistors.

-The first computers were the IBM 7070 in 1960 by IBM and the UNIVAC 1107 in 1962 by Sperry Rand.

-During this generation the magnetic disk, the punch card readers and the high-speed printers were introduced.

THIRD GENERATION (1966-1970)

-The main feature of this generation was the use of the integrated circuit.

-The Burroughs B-2500 was one of the first to include integrated circuits.

- In the late 60's, the minicomputers emerged, as transition element between the third and fourth generations.

FOURTH GENERATION (1971-1980)
