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.
TX-0, TX-2, DEC PDP-1. Whirlwind I was a Cold War -era vacuum-tube computer developed by the MIT Servomechanisms Laboratory for the U.S. Navy. Operational in 1951, it was among the first digital electronic computers that operated in real-time for output, and the first that was not simply an electronic replacement of older mechanical systems.
Sierra (supercomputer) Sierra or ATS-2 is a supercomputer built for the Lawrence Livermore National Laboratory for use by the National Nuclear Security Administration as the second Advanced Technology System. It is primarily used for predictive applications in nuclear weapon stockpile stewardship, helping to assure the safety, reliability, and ...
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations ( computation ). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally ...
The Electronic Delay Storage Automatic Calculator ( EDSAC) was an early British computer. [1] Inspired by John von Neumann 's seminal First Draft of a Report on the EDVAC, the machine was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England.
Power. Electric motor of a vacuum cleaner. Mass. 1 tonne (2,200 lb) Successor. Z2. The Z1 was a motor-driven mechanical computer designed by German inventor Konrad Zuse from 1936 to 1937, which he built in his parents' home from 1936 to 1938. [1] [2] It was a binary, electrically driven, mechanical calculator, with limited programmability ...
The Xerox Alto is a computer system developed at Xerox PARC (Palo Alto Research Center) in the 1970s. It is considered one of the first workstations or personal computers, and its development pioneered many aspects of modern computing. It features a graphical user interface (GUI), a mouse, Ethernet networking, and the ability to run multiple ...
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
