The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers . The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result.
The planar process was developed by Noyce's colleague Jean Hoerni in early 1959, based on the silicon surface passivation and thermal oxidation processes developed by Mohamed M. Atalla at Bell Labs in the late 1950s. [4] [5] [6] Computers using IC chips began to appear in the early 1960s.
John Vincent Atanasoff, OCM, (October 4, 1903 – June 15, 1995) was an American physicist and inventor credited with inventing the first electronic digital computer. [1] Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College (now known as Iowa State University). Challenges to his claim were resolved in 1973 ...
Functionally, EDVAC was a binary serial computer with automatic addition, subtraction, multiplication, programmed division and automatic checking with an ultrasonic serial memory [3] having a capacity of 1,024 44-bit words. EDVAC's average addition time was 864 microseconds and its average multiplication time was 2,900 microseconds.
Colossus was a set of computers developed by British codebreakers in the years 1943–1945 [1] to help in the cryptanalysis of the Lorenz cipher. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations. Colossus is thus regarded [2] as the world's first programmable, electronic, digital computer, although it ...
Computer History Museum. / 37.414371; -122.076817. The Computer History Museum ( CHM) is a museum of computer history, located in Mountain View, California. The museum presents stories and artifacts of Silicon Valley and the information age, and explores the computing revolution and its impact on society.
The Kenbak-1, released in early 1971, is considered by the Computer History Museum to be the world's first personal computer. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971. Unlike a modern personal computer, the Kenbak-1 was built of small-scale integrated circuits, and did not ...
Category. The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. [4]
