First general-purpose computers 2

First general-purpose computers (from Wikipedia) The Atanasoff–Berry Computer (ABC) was among the first fully electronic digital binary computing devices. Conceived in 1937 by Iowa State College physics professor John Atanasoff, and built with the assistance of graduate student Clifford Berry, the machine was not programmable in the modern sense, being designed only to solve systems [...]

Stored-program architecture

Stored-program architecture (from Wikipedia) Several developers of ENIAC, recognizing its flaws, came up with a far more flexible and elegant design, which came to be known as the “stored program architecture” or von Neumann architecture. This design was first formally described by John von Neumann in the paper First Draft of a Report on the [...]


Wikipedia says…. A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. While a computer can, in theory, be made out of almost anything (see misconceptions section), and mechanical examples of computers have existed through much of recorded human history, the first electronic computers were [...]

First general-purpose computers

First general-purpose computers (from Wikipedia) In 1801, Joseph Marie Jacquard made an improvement to the textile loom by introducing a series of punched paper cards as a template which allowed his loom to weave intricate patterns automatically. The resulting Jacquard loom was an important step in the development of computers because the use of punched [...]

Ancient computers

Limited-function ancient computers (from Wikipedia) The history of the modern computer begins with two separate technologies—automated calculation and programmability—but no single device can be identified as the earliest computer, partly because of the inconsistent application of that term. Examples of early mechanical calculating devices include the abacus, the slide rule and arguably the astrolabe and [...]

The first use of the word “computer”

from Wikipedia The first use of the word “computer” was recorded in 1613, referring to a person who carried out calculations, or computations, and the word continued to be used in that sense until the middle of the 20th century. From the end of the 19th century onwards though, the word began to take on [...]
