Computer History Part 1

Hello Friends

I will be starting of with a little bit of Computer History
Here is how the Computers evolved from a counting board in 300 B.C to 2008 Quadra-Core Systems.

300 B.C. The counting board much like the later abacus is believed to be first
used by the Babylonians circa.

1617 John Napier introduced a system called "Napiers Bones," made from horn,
bone or ivory the device allowed the capability of multiplying by adding
numbers and dividing by subtracting.

1623 The first known workable mechanical calculating machine is invented by
Germany's Wilhelm Schickard.

1642 France's Blaise Pascal invents a machine, called the Pascaline, that can
add, subtract, and carry between digits.

1674 Germany's Gottfried Wilhelm Leibnitz creates a machine that can add,
subtract, multiply and divide automatically.

1804 Frances Joseph-Marie Jacquard completes his fully automated loom that is
programmed by punched cards.

1820 Thomas de Colmar creates the first reliable, useful and commercially
successful calculating machine.

1838 Samuel Morse invents a code (later called Morse code) that used different
numbers to represent the letters of the English alphabet and Ten digits.

1847 Siemens is founded.

1868 Christopher Sholes invents the typewriter in the United States utilizing
the QWERTY keyboard.

1875 Tanaka Seizo-sho is established in Japan and later merges with another
company called shibaura Seisaku-sho to form Tokyo Shibarura Denki. Later
this companys name is shortened to the company that we know today, TOSHIBA.

1876 Scottish-Canadian-American Alexander Graham Bell invents the telephone.

1877 The microphone is invented in the United States by Emile Berliner.

1885 American Telegraph and Telephone company (AT&T) is incorporated.

1896 Herman Hollerith starts the Tabulating Machine Company, the company later
becomes the well-known computer company IBM (International Business

1911 Company now known as IBM on is incorporated June 15, 1911 in the state of New York as the Computing - Tabulating - Recording Company (C-T-R), a consolidation of the Computing Scale Company, and The International Time Recording Company.

1924 The Tabulating Machine Company is renamed to IBM.

1927 The first publicly demonstrated TV is demonstrated at Bell Telephone Laboratories.

1928 September 25, 1928, The Galvin Manufacturing Corporation begins, the company will later be known as MOTOROLA.

1930 Galvin Manufacturing Corporation Auto radios begin to be sold as an accessory for the automobile. Paul Galvin coins the name Motorola for the company's new products, linking the ideas of motion and radio.

1933 Canon is established.

1934 The FCC is established.

1936 Germanys Konrad Zuse creates the Z1, one of the first binary digital computers and a machine that could be controlled through a punch tape.

1936 Dvorak keyboard is developed.

1937 Iowa State Colleges John Vincent Atanasoff and Clifford Berry begin work on creating the binary-based ABC (Atanasoft-Berry Computer). Considered by most to be the first electronic digital computer.

1938 The company now known as Hewlett Packard creates its first product the HP 200A.

1939 George Stibitz completes the Complex Number Calculator capable of adding, subtracting, multiplying and dividing complex numbers. This device provides a foundation for digital computers.

1939 Iowa State Colleges John Vincent Atanasoff and Clifford Berry create a prototype of the binary-based ABC (Atanasoft-Berry Computer).

1939 Hewlett Packard is found by William Hewlett and David Packard. The name is decided on the flip of a coin toss. Though it was David who won.

1940 The first handheld two-way radio called the "Handy Talkie" is created by Motorola for the U.S. Army Signal Control.

1941 German Konrad Zuse finishes the Z3, a fully operational calculating machine.

1943 ENIAC (Electronic Numerical Integrator and Computer), the first general-purpose electronic digital calculator begins to be constructed. This computer by most is considered to be the first electronic computer.

1944 The relay-based Harvard-IBM MARK I a large programmable-controlled calculating machine provides vital calculations for the U.S. Navy. Grace Hopper becomes its programmer.

1945 The term bug as computer bug was termed by Grace Hopper when programming the MARK II.

1946 F.C. Williams applies for a patent on his cathode-ray tube (CRT) storing device, an original form of random-access memory (RAM).

1946 ENIAC computer completed.

1946 Robert Metcalfe is born. He is the one who co-invented Ethernet, founded 3Com and formulated Metcalfe's Law

1947 John Bardeen, Walter Brattain and William Shockley invent the first transistor at the Bell Laboratories.

1948 IBM builds the SSEC (Selective Sequence Electronic Calculator). The computer contains 12,000 tubes.

1948 Andreew Donald Booth creates magnetic drum memory, which is two inches long and two inches wide and capable of holding 10 bits per inch.

1948 The 604 multiplying punch, based upon the vacuum tube technology, is produced by IBM.

1949 Claude Shannon builds the first machine that plays chess at the Massachusetts Institute of Technology.

1949 The Harvard-MARK III, the first of the MARK machines to use an internally stored program and indirect addressing, goes into operations again under the direction of Howard Aiken.

1949 The first computer company, Electronic Controls Company is founded by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computer.

1949 The EDSAC performs its first calculation on May 6, 1949.

1949 The small-scale electronic machine (SSEM) is fully operational at Manchester University.

1949 The Australian computer CSIRAC is first ran.

1950 The first electronic computer is created in Japan by Hideo Yamachito.

1950 Steve Wozniak is born August 11, 1950. He is co-founder of Apple Computers

This is a brief history till 1950.
From 1951 to 2008 i will be posting it in next blog.

Please feel free to comment as it will be very valuable to me and help me do better.
