A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
An open PDP-8/E with its logic modules behind the front panel and one dual TU56 DECtape drive at the top A "Straight-8" running at the Stuttgart Computer Museum. The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 [3] (equivalent to about $184,600 in 2024 [4]).
The user would install the device, turn on the computer, load the configuration information from the disk, and the hardware automatically assigned interrupts, DMA, and other needed settings. However, the disks posed a problem if they were damaged or lost, as the only options at the time to obtain replacements were via postal mail or IBM's dial ...
The second-generation computer architectures initially varied; they included character-based decimal computers, sign-magnitude decimal computers with a 10-digit word, sign-magnitude binary computers, and ones' complement binary computers, although Philco, RCA, and Honeywell, for example, had some computers that were character-based binary ...
Hamman Manus R mechanical computer, produced in Germany by the DeTeWe company between 1953 and 1959. A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment ...
Examples of analog computing devices include slide rules, nomograms, and complex mechanisms for process control and protective relays. [6] The Antikythera mechanism , a mechanical device that calculates the positions of planets and the Moon, and the planimeter , a mechanical integrator for calculating the area of an arbitrary 2D shape, are also ...
Apple II computer introduced based on an 8-bit MOS Technology 6502 microprocessor running at 1 MHz with 4 KB of RAM. It had an open architecture, used color graphics, and an audio cassette interface for loading programs and storing data. Later, in July 1978, a floppy disk drive was made available with an elegantly designed interface.
Evolvable hardware (EH) is a field focusing on the use of evolutionary algorithms (EA) to create specialized electronics without manual engineering. It brings together reconfigurable hardware , evolutionary computation , fault tolerance and autonomous systems .
