History of Computers Timeline
-
John Napier
John Napier invented of set of rods with have become known as "Napier's Bones" that could have been used to perform complex calculations. -
Blasie Pascal
During the 17th century he built a machine that could add up to eight digits. -
Joseph Maire Jacquard
he made a device that was call the weaving loom that used to punch cards to replicate designs. Revolutionary step towards computers input. -
Charles Babbage
He invented the deffence engine that was the first machine that actually did input- evcution- output. -
Herman Hollerith
Invented the punched card calculator for it to count the U.S. census in recorded time -
Lee De Forest
He invented the electronic tube. Considered as one of the three technological advances that are key to the development of the computer industry. -
Great Britian
He invented the Colossus which was code breaking. -
Howard H Aiken
He invented the very first programmed controlled calculator -
Ballistic Research Laboratory
Invented the ENIAC. Its capable of 100,000 calculations per secound. -
William B Shocley, Walter H Brattain, John Bardeen
They invented the transistor. The transistor was known as "second generation computers." They use less electricity, give off less heat, smaller and less expensive. -
Institute for Advance Study
The EDVAC is the first computer to use magnetic tape for storage. -
Remington Rand
The UNIVACI was the first computer produced in numbers for business -
Intergrated Circuit
The intergrated Circuit was lead to modern computer "chip" leal to the "third" generation -
Microprocessors
Microprocessors were capabilities of many thousands of transistors made computers,smaller, faster, cheaper, easier to build -
Xerox
the Alto was too expensive and never released. -
Cray I
The Clay 1 is 150 million calculations per second -
Steave Woznick and Steve Jobs
the Apple 2 was the First personal computer -
Commodore's
The PET, C64,CI28,VIC-20 series were affordable to own -
Intel
An 8086 microprocessor added more paper and speed personal computering -
Atari
Good look, durable and easy to use. -
Radio shack, Tandy corp
A TRS-80 is less expensive than apple computers. Some of the most popular personal computers in the 1970's.
