Awal Mula Komputer













1904

Sir John Ambrose Fleming invents the vacuum tube and diode.

1939

John Atanasoff and Clifford Berry invent the first electronic computer at Iowa State University. In 1973 a judge in a patent infringement suit would rule that this research was the idea source for the modern computer.

1940

Konrad Zuse in Germany develops the first programmable calculator using binary numbers and Boolean logic. His program runs on a paper tape.

1943

The world's first electronic valve programmable logic calculator, the Colossus, is built in Britain for the purpose of breaking Nazis codes. On average, Colossus deciphers a coded message in two hours.

1945

Alan Turing publishes his paper on the Universal Machine, laying out the principles of the modern computer.

1945

John Von Neumann, working independently of Turing, writes a document describing the stored-program computer, the basis for the computer industry.

1946

ENIAC, the first electronic digital computer put into operation.

1947

John Bardeen, Walter H. Brattain, and William B. Shockley of Bell Telephone Laboratories invent the transistor.

1949

Bell Labs publishes Shannon's theory of relay logic.

1951

UNIVAC becomes the first commercial computer.

1952

The first database is implemented on RCA's Bizmac computer.

1952

Admiral Grace Hopper develops the first computer compiler, leading to the creation of user-friendly languages and opening the door to a larger universe of computer applications and users.

1954

Gene Amdahl develops the first computer operating system for the IBM 704.

1955

Reynold Johnson develops the first disk drive.

1957

FORTRAN becomes commercially available.

1958

Jack Kilby of Texas Instruments invents the integrated circuit (IC).

1958

Seymour Cray of Control Data Corp. develops the first transistorized computer.

1958

ALGOL computer language, a high-level language designed specifically for programming scientific computations, comes into use.

1959

COBOL computer language is created.

1961

Silicon chips first appear.

1962

First minicomputer comes into use.

1963

Douglas Englebart, SRI, patents the idea of the computer mouse.

1964

IBM releases its Model 360 computer, which will result in $100 billion in sales over its life cycle.

1964

John Kemeny and Thomas Kurtz develop the BASIC computer language. Intel Chairman Gordon Moore suggests that integrated circuits would double in complexity every 18 months. This later becomes known as Moore's Law and is applied to microprocessor speed.

1965

Digital Equipment Corp. (DEC) introduces PDP-8 minicomputer.

1969

PASCAL computer language.

1971

Intel introduces its popular 4004 4-bit microprocessor, starting the evolution of Intel's famous line of 386, 486, and Pentium processors.

1973

Xerox develops first Ethernet Local Area Network (LAN) technology.

1975

Bill Gates and Paul Allen found Microsoft.

1976

Steve Jobs and Steve Wozniak form the Apple Computer Company.

1976

Alan Shugart, IBM, invents the 5.25-inch floppy.

1979

Dan Bricklin introduces the Visicalc spreadsheet.

1980

Philip Estridge, IBM, develops the first hard drive for PCs. It holds 10MB.

1981

IBM introduces the PC.

1982

First IBM-compatible PC clone is introduced by Columbia Data Systems.

1983

Apple Computer introduces the Macintosh computer. Microsoft releases Microsoft Windows 1.0.
