A central processing unit (CPU)—also called a central processor or main processor—is the most important processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs).
Digital Equipment Corporation, using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline.
Konrad Ernst Otto Zuse was a German civil engineer, pioneering computer scientist, inventor and businessman. His greatest achievement was the world's first programmable computer; the functional program-controlled Turing-complete Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse is regarded by some as the inventor and father of the modern computer.
The PDP-1 is the first computer in Digital Equipment Corporation's PDP series and was first produced in 1959. It is famous for being the most important computer in the creation of hacker culture at the Massachusetts Institute of Technology, Bolt, Beranek and Newman and elsewhere. The PDP-1 is the original hardware for playing history's first game on a minicomputer, Steve Russell's Spacewar!
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. Program code was stored on punched film. Initial values were entered manually.
RWTH Aachen University, in German Rheinisch-Westfälische Technische Hochschule Aachen, is a German public research university located in Aachen, North Rhine-Westphalia, Germany. With more than 47,000 students enrolled in 144 study programs, it is the largest technical university in Germany.
A portable computer is a computer designed to be easily moved from one place to another, as opposed to those designed to remain stationary at a single location such as desktops and workstations. These computers usually include a display and keyboard that are directly connected to the main case, all sharing a single power plug together, much like later desktop computers called all-in-ones (AIO) that integrate the system's internal components into the same case as the display. In modern usage, a portable computer usually refers to a very light and compact personal computer such as a laptop, miniature or pocket-sized computer, while touchscreen-based handheld ("palmtop") devices such as tablet, phablet and smartphone are called mobile devices instead.
VEB Kombinat Robotron was the largest East German electronics manufacturer. It was headquartered in Dresden and employed 68,000 people in 1989. Its products included personal computers, SM EVM minicomputers, the ESER mainframe computers, various computer peripherals as well as microcomputers, radios, television sets and other items including cookie press Kleingebäckpresse Typ 102.
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 BUNCH was the nickname for the group of mainframe computer competitors of IBM in the 1970s. The name is derived from the names of the five companies: Burroughs, UNIVAC, NCR, Control Data Corporation (CDC), and Honeywell. These companies were grouped together because the market share of IBM was much higher than all of its competitors put together.
The Computer Museum was a Boston, Massachusetts, museum that opened in 1979 and operated in three locations until 1999. It was once referred to as TCM and is sometimes called the Boston Computer Museum. When the museum closed and its space became part of Boston Children's Museum next door in 2000, much of its collection was sent to the Computer History Museum in California.
A computer museum is devoted to the study of historic computer hardware and software, where a "museum" is a "permanent institution in the service of society and of its development, open to the public, which acquires, conserves, researches, communicates, and exhibits the tangible and intangible heritage of humanity and its environment, for the purposes of education, study, and enjoyment", as defined by the International Council of Museums.
A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable. A second-generation computer, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic-core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation computer.
The K 1840, full name RVS K 1840 is a minicomputer from the German Democratic Republic (GDR). Its development began in August 1985 at VEB Robotron Elektronik in Dresden, and it went into production in 1988.
Louis-André-Gabriel Bouchet was a French historical painter and a pupil of Jacques-Louis David. He painted subjects from sacred and profane history, poetry, and portraits. He won the Prix de Rome in 1797, and continued to exhibit until 1819. Charles Gabet does not mention the date of his birth or death.
Aachen Town Hall is a landmark of cultural significance located in the Altstadt of Aachen, Germany. It was built in the Gothic style in the first half of the 14th century.
The Aachen Cathedral Treasury is a museum of the Roman Catholic Diocese of Aachen under the control of the cathedral chapter, which houses one of the most important collections of medieval church artworks in Europe. In 1978, the Aachen Cathedral Treasury, along with Aachen Cathedral, was the first monument on German soil to be entered in the List of UNESCO World Heritage Sites. The treasury contains works from Late Antique, Carolingian, Ottonian, Staufen, and Gothic times. The exhibits are displayed in premises connected to the cathedral cloisters.
Stuttgart Computer Museum is a collection of calculators, mechanical calculating machines, and analog and digital computers at the Vaihingen campus of University of Stuttgart, Germany established in 1997.
