the beginning
In France, Joseph Marie Jacquard invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards. -
1822...
English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. The project, funded by the English government, is a failure. More than a century later, however, the world’s first computer was actually built. -
1890...
Herman Hollerith designs a punch card system to calculate the 1880 census, accomplishing the task in just three years and saving the government $5 million. He establishes a company that would ultimately become IBM. -
1938...
Alan Turing presents the notion of a universal machine, later called the Turing machine, capable of computing anything that is computable. The central concept of the modern computer was based on his ideas. -
ENIAC
The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers. ENIAC was also the first machine to use more than 2,000 vacuum tubes, using nearly 18,000 vacuum tubes. Storage of all those vacuum tubes and the machinery required to keep the cool took up over 167 square m -

First Generation ( 1951-1958 )
The first generation computers used bulbs for processing information. Programming is done through the machine language. The memories were built with thin tubes of liquid mercury and magnetic drums. Operators entering data and programs in special code by punched cards. Internal storage was achieved with rapidly spinning drum on which a read / write magnéticas.Estos marks placed computers used vacuum valve . So they were extremely large, generated a lot of heat . -
1953...
Grace Hopper develops the first computer language, which eventually becomes known as COBOL. Thomas Johnson Watson Jr., son of IBM CEO Thomas Johnson Watson Sr., conceives the IBM 701 EDPM to help the United Nations keep tabs on Korea during the war. -
1954...
The FORTRAN programming language is born. -

The First Generation begins with the Commercial Installation UNIVAC by Eckert and Mauchly CONSTRUCTED . The processor of UNIVAC weighed 30 tons and required the entire living space UN 20 40 empanadas. -
Second Generation (1959-1964)
Compatibility Transistor Limited replaces the vacuum valve used n the first generation. The second generation computers were faster , smaller and lower ventilation needs . These computers also used magnetic core networks 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 . -
programs
Computer programs also improved. COBOL developed during the 1st generation was commercially available . Programs written for a computer could be transferred to another with minimal effort . Writing a program already required not fully understand the computer hardware . -
1969...
group of developers at Bell Labs produce UNIX, an operating system that addressed compatibility issues. Written in the C programming language, UNIX was portable across multiple platforms and became the operating system of choice among mainframes at large companies and government entities. Due to the slow nature of the system, it never quite gained traction among home PC users. -
1970
The newly formed Intel unveils the Intel 1103, the first Dynamic Access Memory (DRAM) chip. -
Fourth Generation ( 1971-1981 )
Microprocessor, memory chips , micro-miniaturization , two improvements in computer technology marks the beginning of the fourth generation replacement memories with magnetic cores, the silicon chip and the placement of many more components on a chip : product microminiaturization of electronic circuits. -
Steve Jobs
Steve Jobs and Steve Wozniak start Apple Computers on April Fool’s Day and roll out the Apple I, the first computer with a single-circuit board. -
evolution
Radio Shack's initial production run of the TRS-80 was just 3,000. It sold like crazy. For the first time, non-geeks could write programs and make a computer do what they wished. Jobs and Wozniak incorporate Apple and show the Apple II at the first West Coast Computer Faire. It offers color graphics and incorporates an audio cassette drive for storage. -
1978
Accountants rejoice at the introduction of VisiCalc, the first computerized spreadsheet program. -
1981
The first IBM personal computer, code-named “Acorn,†is introduced. It uses Microsoft’s MS-DOS operating system. It has an Intel chip, two floppy disks and an optional color monitor. Sears & Roebuck and Computerland sell the machines, marking the first time a computer is available through outside distributors. It also popularizes the term PC. -
1990
Tim Berners-Lee, a researcher at CERN, the high-energy physics laboratory in Geneva, develops HyperText Markup Language (HTML), giving rise to the World Wide Web. -
1996
Sergey Brin and Larry Page develop the Google search engine at Stanford University. -
1997
Microsoft invests $150 million in Apple, which was struggling at the time, ending Apple’s court case against Microsoft in which it alleged that Microsoft copied the “look and feel†of its operating system. -
1999
he term Wi-Fi becomes part of the computing language and users begin connecting to the Internet without wires. -
