Douglas Engelbart Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an American engineer and inventor, and an early computer and Internet pioneer. 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.

Atari Sierra Sierra was the code name for a 16-bit/32-bit personal computer designed by Atari's Sunnyvale Research Lab (SRL) starting around 1983. The design included a new GPU known as "Silver and Gold", a powerful sound synthesizer known as AMY, and a new operating system code-named "Eva". The two-chip GPU was collectively known as Rainbow, and the system is sometimes referred to by this name. The CPU had not been chosen, but the Motorola 68000 and Intel 286 were being considered.

History of personal computers The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1980s. The 1981 launch of the IBM Personal Computer coined both the term "Personal Computer" and "PC". 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. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.

AlphaWindows AlphaWindows was a proposed industry standard from the Display Industry Association (an industry consortium in California) in the early 1990s that would allow a single CRT screen to implement multiple windows, each of which was to behave as a distinct computer terminal. Individual vendors offered products based on this in 1992 through the end of the 1990s. and after,

Scrollbar A scrollbar is an interaction technique or widget in which continuous text, pictures, or any other content can be scrolled in a predetermined direction (up, down, left, or right) on a computer display, window, or viewport so that all of the content can be viewed, even if only a fraction of the content can be seen on a device's screen at one time. It offers a solution to the problem of navigation to a known or unknown location within a two-dimensional information space. It was also known as a handle in the very first GUIs. They are present in a wide range of electronic devices including computers, graphing calculators, mobile phones, and portable media players. The user interacts with the scrollbar elements using some method of direct action, the scrollbar translates that action into scrolling commands, and the user receives feedback through a visual updating of both the scrollbar elements and the scrolled content.

Barebone computer A barebone computer is a partially assembled platform or an unassembled kit of computer parts allowing more customization and lower costs than a retail computer system. They are available for desktop computer, notebook (see barebook) and server purposes, and in nearly any form factor. Manufacturers are also able to produce systems of a specialized or non-standard form factor, since the system is sold as a pre-built unit, with the motherboard and power supply already installed.

AmigaOS AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. Later versions were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent release, AmigaOS 4.

Plug computer A plug computer is an external device, often configured for use in the home or office as a compact computer. It consists of a high-performance, low-power system-on-a-chip processor with several I/O ports (USB ports, ...) and typically runs any of a number of Linux distributions. Most versions do not have provisions for connecting a display and are best suited as for running media server, back-up services, file sharing and remote access functions, thus acting as a bridge between in-home protocols such as Digital Living Network Alliance (DLNA) and Server Message Block (SMB) and cloud based services. There are, however, plug computer offerings that have analog VGA monitor and/or HDMI connectors, which, along with multiple USB ports, permit the use of a display, keyboard, and mouse, thus making them full-fledged, low-power alternatives to desktop and notebook computers.

Computer terminal A computer terminal is an electronic or electromechanical hardware device that is used for entering data into, and displaying data from, a computer or a computing system. Early terminals were inexpensive devices but very slow compared to punched cards or paper tape for input, but as the technology improved and video displays were introduced, terminals pushed these older forms of interaction from the industry. A related development was timesharing systems, which evolved in parallel and made up for any inefficiencies of the user's typing ability with the ability to support multiple users on the same machine, each at their own terminal.

Pointing device A pointing device is an input interface (specifically a human interface device) that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. CAD systems and graphical user interfaces (GUI) allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer (or cursor) and other visual changes. Common gestures are point and click and drag and drop.
