Project Genie
Project Genie was a computer research project started in 1964 at the University of California, Berkeley. It produced an early time-sharing system including the Berkeley Timesharing System, which was then commercialized as the SDS 940. History Project Genie was funded by J. C. R. Licklider, the head of ARPA's Information Processing Techniques Office at that time. The project was a smaller counterpart to MIT's Project MAC. The Scientific Data Systems SDS 940 was created by modifying an SDS 930 24-bit commercial computer so that it could be used for timesharing. The work was funded by ARPA and directed by Melvin W. Pirtle and Wayne Lichtenberger at UC Berkeley. Butler Lampson, Chuck Thacker, and L. Peter Deutsch were among the young technical leaders of that project. When completed and in service, the first 940 ran reliably in spite of its array of tricky mechanical issues such as a huge disk drive driven by hydraulic arms. It served about forty or fifty users at a time and stil ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Computer
A computer is a machine that can be Computer programming, programmed to automatically Execution (computing), carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as Computer program, ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the Computer hardware, hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots.

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

ILLIAC IV
The ILLIAC IV was the first massively parallel computer. The system was originally designed to have 256 64-bit floating-point units (FPUs) and four central processing units (CPUs) able to process 1 billion operations per second. Due to budget constraints, only a single "quadrant" with 64 FPUs and a single CPU was built. Since the FPUs all processed the same instruction — etc. — in modern terminology, the design would be considered to be single instruction, multiple data, or SIMD. The concept of building a computer using an array of processors came to Daniel Slotnick while working as a programmer on the IAS machine in 1952. A formal design did not start until 1960, when Slotnick was working at Westinghouse Electric Corporation and arranged development funding under a United States Air Force contract. When that funding ended in 1964, Slotnick moved to the University of Illinois Urbana-Champaign and joined the Illinois Automatic Computer (ILLIAC) team. With funding f ...

ALOHAnet
ALOHAnet, also known as the ALOHA System, or simply ALOHA, was a pioneering computer networking system developed at the University of Hawaii. ALOHAnet became operational in June 1971, providing the first public demonstration of a wireless packet data network. The ALOHAnet used a new method of medium access, called ''ALOHA random access'', and experimental ultra high frequency (UHF) for its operation. In its simplest form, later known as Pure ALOHA, remote units communicated with a base station (Menehune) over two separate radio frequencies (for inbound and outbound respectively). Nodes did not wait for the channel to be clear before sending, but instead waited for acknowledgement of successful receipt of a message, and re-sent it if this was not received. Nodes would also stop and re-transmit data if they detected any other messages while transmitting. While simple to implement, this results in an efficiency of only 18.4%. A later advancement, Slotted ALOHA, improved the effi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

NLS (computer System)
NLS (oN-Line System) was a revolutionary computer collaboration system developed in the 1960s. It was designed by Douglas Engelbart and implemented by researchers at the Augmentation Research Center (ARC) at the SRI International, Stanford Research Institute (SRI). It was the first computer system to employ the practical use of hypertext links, a computer mouse, raster scan, raster-scan computer monitor, video monitors, information organized by relevance, GUI, screen windowing, presentation programs, and other modern computing concepts. It was funded by ARPA (the predecessor to DARPA, Defense Advanced Research Projects Agency), NASA, and the United States Air Force, US Air Force. The NLS was demonstrated in "The Mother of All Demos". Development Douglas Engelbart developed his concepts while supported by the US Air Force from 1959 to 1960 and published a framework in 1962. The strange acronym, NLS (rather than OLS), was an artifact of the evolution of the system. Engelbart's f ...

Douglas Engelbart
Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an American engineer, inventor, and a pioneer in many aspects of computer science. He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, and the development of hypertext, networked computers, and precursors to graphical user interfaces. These were demonstrated at The Mother of All Demos in 1968. Engelbart's law, the observation that the intrinsic rate of human performance is exponential, is named after him. The "oN-Line System" ( NLS) developed by the Augmentation Research Center under Engelbart's guidance with funding mostly from the Advanced Research Projects Agency (ARPA), later renamed Defense Advanced Research Projects Agency (DARPA), demonstrated many technologies, most of which are now in widespread use; it included the computer mouse, bitmapped sc ...
