History of computing

Posted by jonano , 29 December 2007 · 1,620 views

General
Hi,

In the past I assembled some text about the history of computing on my old atomasoft web site, here I paste the text again since it's a good information and funny to read:

1623 First mechanical calculator
German inventor Wilhelm Schickard invents the first mechanical calculator. Records detailing the machine's workings were lost during the Thirty Years' War.

1642 Pascal's machine

Nineteen-year-old Blaise Pascal of Rouen, France, begins work on a digital adding machine to help his father, a local administrator, calculate taxes. When completed two years later, the machine can add and subtract numbers up to eight digits long. Pascal later becomes an esteemed mathematician and philosopher.

1673 Liebniz builds calculator

German philosopher and mathematician Gottfriend Liebniz builds a working model of a calculating machine using gears and rods. His machine, called the Stepped Reckoner, can multiply, divide, and calculate square roots.

1914 Watson joins IBM

Thomas Watson Sr. joins the Tabulating Machine Company, which he reorganizes and reinvents as IBM. His son, Thomas Watson Jr., will succeed him as IBM chairman in 1956 and successfully shift the company's focus to computers.

1939 Hewlett-Packard founded

Stanford classmates David Packard and William Hewlett start a company in Hewlett's Palo Alto garage. The company builds a wide range of electronic measurement instruments. The company's handheld electronic calculator, introduced in 1972, is a bestseller. The company will become a major supplier of personal computers and laser printers. Hewlett's garage is later declared a registered historical landmark.

1939-1942 Atanasoff-Berry Computer

John Atanasoff, a physics professor at Iowa State University, and graduate student Clifford Berry begin building the Atanasoff-Berry Computer. Work on the computer continues from 1939 to 1942. In 1941, Atanasoff shows the computer to John Mauchly and Presper Eckert, who are constructing an electronic digital computer at the University of Pennsylvania's Moore School. In a controversial decision decades later, the Supreme Court will decide that Atanasoff, not Mauchly and Eckert, was the true inventor of the electronic computer.

1940 Stibitz develops electronic computer

George Stibitz of Bell Labs develops an early digital calculator to speed up his work computing relay switching. He devises an electronic adding machine, using dry cell batteries, metal strips from a tobacco can, and flashlight bulbs. The adding machine, called the Model I Complex Calculator, is used at Bell for the next nine years.

1943 Colossus computer built in England

A team of English engineers completes the Colossus, an electronic digital computer developed to break codes generated by German code-writing machines. The Colossus and earlier code-breaking machines are largely based on the theoretical work of English mathematician Alan Turing. Turing is best known for his work in artificial intelligence, including the Turing Test, which measures a machine's capacity for human thought.

1944 Harvard engineers complete work on the Mark I

In February, Howard Aiken and a team of Harvard engineers complete the Mark I computer after five years of work. The Mark I is fifty-one feet long and eight feet high, weighs thirty-five tons, and contains about five hundred miles of wire. Programmed with paper tape punched with coded instructions, the machine can add, subtract, multiply, and divide. The machine is used by the Navy for ballistics.

1945 Grace Hopper finds a bug in the Mark I

Grace Hopper, a computer scientist and mathematician working for the Navy, finds an actual moth in a vacuum tube inside the Mark I. Although the term bug has been used to describe mechanical and electronic glitches for decades, this is the first documented occasion of a bug being caused by an actual bug. Hopper, who taught mathematics until World War II broke out, later develops the Flow-Matic compiler. Her pioneering work in compilers and computer code paves the way for increasingly sophisticated computer languages. In 1991, she becomes the first woman to win the prestigious National Medal of Technology.

Von Neumann and EDVAC (Electronic Discrete Variable Automatic Calculator)

After visiting the Moore School and observing the development of the Electronic Numeric Integrator and Computer (ENIAC), esteemed scientist John Von Neumann, best known for his work on the Manhattan Project, circulates a report proposing the addition of storage memory to the machine. He calls the modified machine he proposes EDVAC. This memo, called "Report on EDVAC," details the engineering behind ENIAC, and helps raise awareness of electronic computing throughout the country.

Vannevar Bush publishes influential essay

The Atlantic publishes an essay titled "As We May Think," by Vannevar Bush, inventor and Manhattan Project scientist. This essay, about the evolution of computers into tools that can facilitate human thought, significantly influences Doug Engelbart years later. Inspired by Bush, Engelbart will develop the first graphical user interface using icons, windows, and a mouse, which he demonstrates at a computer conference in 1968.

1946 Electronic Numeric Integrator and Computer (ENIAC)

One of the world's first electronic computers is delivered to the U.S. Army. The computer, developed by John Mauchly and Presper Eckert of the University of Pennsylvania's Moore School, was commissioned to compute ballistics firing tables used in World War II but was not completed until several months after the war ended.

1947 Transistor invented

Will Shockley, Walter Braitton, and John Bardeen of Bell Telephone Laboratories invent the transistor, initiating the era of modern electronics. The tiny transistor soon replaces the cumbersome vacuum tubes previously used in electronic equipment. The trio will win the Nobel Prize for Physics in 1956.

1948 UNIVAC (Universal Automatic Computer)

John Mauchly and Presper Eckert found the Eckert-Mauchly Computer Company, which will manufacturer the world's first commercially available electronic digital computer, UNIVAC. The U.S. Census Bureau uses UNIVAC to calculate the 1950 census results.

1949 An Wang invents memory core

Twenty-eight-year-old, Shanghai-born An Wang invents the magnetic memory core and founds Wang Laboratories three years later. The magnetic memory core serves as the basis for all computer memory until the invention of the microchip. Wang's company becomes a successful calculator and computer manufacturer, and Wang will later break ground in word processing systems.

1949 English scientists develop first computer with memory

The Ferranti Mark I, designed by Frederic Williams and Thomas Kilburn at Manchester University, and the Electronic Delay Storage Automatic Calculator (EDSAC) become the first stored-program computers.

1949 Jay Forrester develops magnetic computer memory

Jay Forrester, founder of the Digital Computer Lab at M.I.T., devises the first random-access magnetic memory. The Digital Computer Lab had developed the Whirlwind I, a digital computer, several years earlier under Forrester's leadership.

1952 IBM accused of computer monopoly

The Justice Department files suit against IBM for allegedly monopolistic practices in its computer business. IBM will be plagued by antitrust litigation for the next thirty years.

1957 Digital Equipment Corp. founded

Kenneth Olsen, a member of the M.I.T. team that built the Whirlwind in 1951, founds Digital Equipment Corp. Olsen starts the company in an old textile mill with seventy thousand dollars from George Doriot, who started the first non-family-owned venture capital firm in the United States. The company becomes the world's second-largest computer company by the 1970s but loses ground in the 1990s. In 1998, Compaq buys the company.

1957 ARPA proposed (November)

Secretary of Defense Neil McElroy proposes the creation of a defense department research agency, later known as the Advanced Research Projects Agency (ARPA). In the late 1960s, ARPA will commission the construction of a distributed computer network called ARPANET, which will become the foundation for the Internet.

1958 ARPA chartered

The U.S. government approves McElroy's proposal to develop an advanced research agency at the Department of Defense. Government funding for science and research flows freely after the Soviet Union's launch of Sputnik, the first satellite, threw U.S. officials into a panic.

1958 Integrated circuit invented

Jack St. Clair Kilby of Texas Instruments builds an integrated circuit that includes multiple components on a tiny silicon chip. Robert Noyce, of Fairchild Semiconductor and future cofounder of Intel, independently develops an integrated circuit early in 1959.

1963 Douglas Engelbart patents the mouse

Doug Engelbart, a researcher at Stanford Research Institute, working on a grant from ARPA, develops and patents the mouse. Heavily influenced by a 1945 essay written by Vannevar Bush about human-computer interaction, Engelbart hopes to develop computers that can help people think more fluidly.

1964 Moore's law

Gordon Moore, future Intel cofounder, suggests integrated circuits will double in complexity every year. Moore's law proves true as computer chips become faster and faster.

1964 IBM System 360 released

With the introduction of the System 360 family of computers, all IBM machines can now use the same software. Previously, all IBM machines were individually programmed. The company takes a major risk in releasing System 360 because the series renders all existing IBM systems obsolete. The risk, however, will pay off and send IBM's profits skyrocketing.

1964 Paul Baran publishes paper on package switching networks

Paul Baran, of Rand Corp., proposes a design for a communications network capable of surviving a nuclear attack. He publishes a paper describing a network that replaces a few vulnerable hubs with a labyrinth of computer connections. Every message is broken into data "packets," which are routed throughout the network then reassembled at the destination computer. Although Baran stops work on the project in 1965, his papers and personal input inform Larry Roberts' design of ARPANET.

1966 Robert Taylor becomes director of IPTO

Computer scientist Robert Taylor becomes director of ARPA's Information Processing and Techniques Office (IPTO). His first priority is to deal with the demands of universities and research institutions clamoring for supercomputers. He theorizes that by linking computers together electronically, universities will be able to reduce redundancy in their work, and his department can save money by funding fewer grants for computers.

1966 Larry Roberts joins IPTO (December)

Taylor hires Larry Roberts to oversee his cost-cutting network program. Taylor guides the development of ARPANET.

1967 Larry Roberts presents ARPANET paper

At a computer conference in Tennessee, Larry Roberts presents a paper outlining the basics of ARPANET, a computer network that lacks a central hub. ARPANET becomes the foundation for the Internet and World Wide Web.

1968 Robert Noyce and Gordon Moore found Intel

Robert Noyce and Gordon Moore leave Fairchild Semiconductor to create their own semiconductor company, Intel.

1968 Douglas Engelbart demonstrates the mouse (May)

Stanford Research Institute's Douglas Engelbart presents a computer system with a point-and-click interface and a mouse at the Joint Computer Conference. The first computer with a mouse will not be introduced to the market for another thirteen years.

1968 ARPA requests proposals for network (July)

In July, ARPA sends out a request for proposals to build machines that will act as switchboards for the proposed ARPANET. In September, Cambridge-based BBN (Bolt, Baranek and Newman) submits a proposal to build Interface Message Processors, computers that will serve as ARPANET's backbone. When the company wins the contract, the staff receives a message from Massachusetts Senator Edward Kennedy, congratulating them on promoting religious tolerance with their "Interfaith" Message Processor.

1969 Compu-Serv founded

Compu-Serv, which later becomes online service CompuServe, is founded to sell and coordinate time-sharing on supercomputers.

1969 ARPANET officially commissioned (January)

BBN's contract to build a series of Interface Message Processors-computers to serve as the backbone for ARPANET-commences.

1969 UCLA receives first IMP (August)

The first Interface Message Processor (IMP) arrives at the University of California-Los Angeles. Its installation creates the first ARPANET node. Three more of the refrigerator-sized computers are installed by the end of the year, at Stanford Research Institute, University of California-Santa Barbara, and the University of Utah, and ARPANET is launched.

1970 ALOHANET goes online

Developed by Norman Abramson at the University of Hawaii, ALOHANET launches. The computer network transmits data using small radios. When two computers try to send data at the same time, the computers are instructed to send the data again after a short pause. This simple system becomes the basis for Robert Metcalfe's Ethernet.

1970 Xerox PARC

Xerox forms an advanced research center, the Palo Alto Research Center (PARC). Robert Taylor, former head of ARPA, who launched the ARPANET initiative, is hired as head of the computer science division. Under Taylor, PARC recruits an elite corps of leading scientists, who do much of the early thinking about graphical user interfaces (GUI) and other advanced personal computing issues. Robert Metcalfe will invent Ethernet at PARC, and the GUI and mouse system used on a PARC workstation will inspire Steve Jobs to build a computer with a point-and-click interface.

1971 Vinton Cerf and Robert Kahn commissioned to extend ARPANET

Vinton Cerf, head of the International Network Working Group, and Robert Kahn are commissioned by the government to extend ARPANET for military and government use. The two begin to research ways to connect ARPANET and other networks. By 1974, the pair will release a paper describing Transmission Control Protocol (TCP), which will allow networks to communicate with each other. In 1978, Cerf helps develop Internet Protocol (IP), which will help govern the way messages are sent through the network. In 1983, ARPANET will switch to TCP/IP and becomes a public network.

1971 Intel markets CPU

Intel markets its first central processing unit (CPU), a 4-bit, 108-kHz 4004 chip.

Hewlett-Packard introduces the world's first electronic calculator. The calculator is a phenomenal success, and Hewlett-Packard proves adept at adjusting the company to new technological trends. In the coming years, the company will become a leading personal computer and printer supplier.

1973 Xerox PARC creates Alto

Alto, a workstation using a mouse, graphics, and a point-and-click interface, is completed in February. Despite the machine's popularity within Xerox, the Alto is never marketed commercially. Some of its features appear in the Xerox STAR workstation, released in 1981; but with a sixteen-thousand-dollar price tag, the machine does not become a commercial success. After seeing a demonstration of Alto in 1979, Steve Jobs and a team of Apple engineers add many of its features to the Apple Lisa, released in 1983, and the Macintosh, released in 1984.

1973 Ethernet

Robert Metcalfe of Xerox PARC develops Ethernet, a way to connect several computers together. Ethernet will become the de facto standard for linking computers, printers, and other electronic devices. Metcalfe describes Ethernet, inspired by ALOHANET, in his doctoral thesis for Harvard.

1973 Norway and England connect to ARPANET

Norway and England both log on to ARPANET, creating the first international connection.

1974 TCP design published

Cerf and Kahn publish specifications for a Transmission Control Protocol (TCP). The program will essentially transform the closed ARPANET network into the open, public Internet by allowing different networks to communicate with each other.

1974 Gary Kildall develops CP/M

Gary Kildall writes an operating system called CP/M (control program/monitor) for small computers using Intel chips. The operating system serves as the model for Q-DOS from Seattle Computer Products, which later licenses its system to Microsoft. Q-DOS (under its new name, MS-DOS) becomes the operating system for the IBM PC and all its clones, ensuring Microsoft a steady cash flow to fund the corporation's growth.

1974 MITS Altair launched

MITS (Micro Instrumentation Telemetry Systems), a company owned by Ed Roberts of Albuquerque, New Mexico, introduces a microcomputer kit for about $500 that lets hobbyists build their own machine. When the Altair appears on the cover of Popular Electronics, orders flood in, even though the computer does more than blink some red lights. The Popular Electronics, issue featuring Altair, however, inspires Paul Allen and Bill Gates to start a company producing software for the machine. Gates drops out of Harvard in 1975, and the two moved to Albuquerque to form their own company, Micro-soft (later, Microsoft).
