Early GEC 2-pin plug and socket as depicted in the 1893 GEC catalogue. The earliest domestic plug and socket is believed to be that patented by T. T. Smith in 1883. [27] This was shortly followed by patents from W. B. Sayers and G. Hookham; these early designs had rectangular plugs with contact plates on either side.
Illustration of "Tripin" 3-pin earthed plug dated 1911. The earthed consumer plug has several claimants to its invention. In Britain, a 1911 book [9] dealing with the electrical products of A. P. Lundberg & Sons of London describes the "Tripin" earthed plug available in 2.5 amp and 5 amp models.
Computer graphics is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world.
It defines a plug with an earthing pin, and two flat current-carrying pins which form an inverted V-shape. [10] The flat pins measure 6.5 by 1.6 mm (0.256 by 0.063 in) and are set at 30° to the vertical at a nominal pitch of 13.7 mm (0.539 in).
A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.
TGA graphics are built into the motherboards of Tandy computers. The PCjr uses a custom monitor with a unique 18-pin plug, [15] but an adapter (with the same DE-9 connector and pinout as IBM's CGA/EGA) can connect it to the IBM Color Display or similar 4-bit digital RGBI monitor. [16] The Tandy 1000 provides the DE-9 connector directly. [17]
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [ 1 ] as well as many monitors, projectors and HD television sets.
