In the U.S., made a census - the first time this machine was involved considers established Herman Hollritom.

1935
The Corporation International Business Machines (IBM) launched large-scale computers IBM-601.

1937
Mathematician Alan Turing created "a mathematical model of the computer, and later given the name" Turing machine ".

1938
Conrad Tsuze, friend and colleague of the famous Werner von Braun, created in Berlin, one of the first computers - VI.

1943
Howard Eyken creates "ASCC Mark I" - a machine deemed grandfather of modern computers. "Mark" weighed more than 7 tons and consisted of 750 000 parts. The machine was used for military purposes - for the calculation of artillery tables.

1945
John von Nyumann razrabatal theoretical computer model of the device (computer background Nyumanna) - the world's first description of a computer, use the downloadable program from the outside.

1945
Mochli and Ekkret created ENIAC - the most ambitious and powerful vacuum tube computer that era. The computer weighs over 70 tons and contains a nearly 18 thousand electron tubes! The working frequency of your computer does not exceed 100 kHz (a few hundred transactions per second).

1947
Staff Shokli William Bell, John Bardin, and Walter Bertteyn created the first transistor. However, some scientists now speak of the interim "coincidence" the creation of the transistor with the famous "catastrophe UFOs in New Mexico. In 1956 the creators of the transistor will be awarded the Nobel Prize.

1949
A Short Code - a first programming language.

1956
The Massachusetts Institute of Technology created the first computer based on the transistor. IBM established the first store of information - a prototype of the hard disk - hard disk KAMAS 305.

1957
Group Depona Bekusa created the programming language Fortran (FORmula TRANslation).

1958-1959
Jack Kilbi and Robert Neuss created a unique chain of logic elements on the surface of silicon crystal, connected aluminum contacts - the first prototype of microprocessor integrated circuits.

1960
AT designed the first modem - a device to transfer data between computers. Joint team of the largest manufacturers of computers has developed a programming language COBOL. Created by the most popular programming language 60-x ALGOL.

1963
Douglas Engelbart received a patent for the invention of his arm - "Mouse".

1964
Professor John Thomas Kemeni and Kurd develop a simple programming language - BASIC.

1967
Born the concept of "computer on a single crystal. The world gives birth to the microprocessor.

Wayne Pikett develops the concept of "hard drive" - a hard magnetic disk. Douglas Engelbart demonstrates in Stanford Institute hypertext system, word processor, working with mouse and keyboard. Robert Neuss, and Gordon Moore founded a company Intel.

1969
Kenneth Thompson and Dennis Ritchie created the operating system UNIX. The first connection between two computers. At a distance of 500 km was transferred to the word LOGIN (able to pass only two letters). Intel introduced the first chip memory (RAM) capacity of 1 KB. Xerox laser technology creates a backup image, which after many years, will form the basis of printing technology in laser printers. First "Xeroxes.

1970
The first four largest computer research dollars are connected by a network APRANet - progenitor of modern Internet.
