(While HP-GL is used internationally, GP-GL is more prevalent in some markets.) Another alternative is Digital Microprocessor Plotter Language (DMPL), developed by Houston Instrument, which has several built-in functions that are not present in HP-GL, such as built-in fonts, the ability to do closed area fill with a single command, and built-in smoothing algorithms. Other plotters have their own native languages, which often work faster than HP-GL with programs that support them... http://Hardware.e-articles.info/title/Plotters'-Control-Languages/ http://Hardware.e-articles.info/title/Plotters'-Control-Languages/ Sat, 19 Jun 2010 01:41:22 GMT The one revolution that has changed the faces of both offices and forests around the world was the photocopier. Trees plummet by the millions to provide fodder for the duplicate, triplicate, megaplicate. Today's non-impact, bit image laser printer owes its life to this technology.

Instead of using solvent based inks that are fixed (that is, that dry) by evaporation or absorption into the print medium, they use inks that harden, changing phase from liquid to solid. Because of this phase-change, this form of inkjet is often called a phase-change inkjet. The ink starts as solid sticks or chunks of specially dyed wax... http://Hardware.e-articles.info/title/Phase-Change-Inkjets/ http://Hardware.e-articles.info/title/Phase-Change-Inkjets/ Sat, 19 Jun 2010 03:57:32 GMT The most common inkjet technology is called thermal because it uses heat inside its print head to boil a tiny quantity of water based ink. Boiling produces tiny bubbles of steam that can balloon out from the nozzle orifices of the print head. The thermal mechanism carefully controls the bubble formation. It can hold the temperature in the nozzle at just the right point to keep the ink bubble from bursting... http://Hardware.e-articles.info/title/Thermal-Inkjets/ http://Hardware.e-articles.info/title/Thermal-Inkjets/ Sat, 19 Jun 2010 04:23:37 GMT Line printer have two distinct operating modes. They can accept text as ASCII characters, select their bit patterns from an internal character generator, and print them as a single sequence on each line, one line at a time. Alternately, in their graphics modes, they accept bit image data from your PC and simply render the bit patterns chosen by your PC on paper. Those bit patterns can include both text characters and graphics... http://Hardware.e-articles.info/title/Line-Printers/ http://Hardware.e-articles.info/title/Line-Printers/ Sat, 19 Jun 2010 05:31:42 GMT A number of different terms describe the technologies used in the LCD panels themselves, terms like supertwist, double supertwist, and triple supertwist. In effect, the twist of the crystals controls the contrast of the screen, so triple supertwist screens have more contrast than ordinary supertwist. The history of laptop and notebook computer displays has been led by innovations in LCD technology. Invented by RCA in the 1960s (General Electric still receives royalties on RCA's basic patents), LCDs came into their own with laptop computers because of their low power requirements, light weight, and ruggedness... http://Hardware.e-articles.info/title/LCD-Technologies/ http://Hardware.e-articles.info/title/LCD-Technologies/ Sat, 19 Jun 2010 06:39:47 GMT The VGA system requires monitors capable of synchronizing in a fixed horizontal sweep frequency of 31.5 KHz.

Rather, it is a connection standard that describes a new, high speed bus connection between the video system in your PC and its microprocessor and memory. In effect it is a specialized expansion bus, one that recalls local bus designs. You might even consider it the second generation of local bus for video systems... http://Hardware.e-articles.info/title/Advanced-Graphic-Port/ http://Hardware.e-articles.info/title/Advanced-Graphic-Port/ Mon, 14 Jun 2010 08:55:57 GMT The design of the PC requires that every video board actually be two boards in one. All video boards need VGA compatibility to assure that they will work properly as your PC wakes up. At boot time, the video board must work in its most primitive mode-one compatible with all PC software written since time began. All PCs boot in VGA mode and remain in that mode until your operating system loads the proper software drivers to move your display system into its high resolution operating mode... http://Hardware.e-articles.info/title/Video-Board-Types/ http://Hardware.e-articles.info/title/Video-Board-Types/ Mon, 14 Jun 2010 09:23:15 GMT Although beauty lies in the beholder's eye, the first PC's screen was something only a zealot (or a secretary under duress) could love-ghostly green text that lingered on as the screen scrolled, crude block graphics, the kinds of stuff you thought you outgrew when you graduated from crayons to pencils. The most positive thing you could say for the original display system, the Monochrome Display Adapter, or MDA, that IBM introduced with its first PC in 1981, was that you never had any trouble making up your mind about what you wanted. Nor did you have to worry about compatibility-or such trivialities as art, color, aesthetics, or creativity. Only later in 1982 did IBM add color in its Color Graphics Adapter or CGA system, creating an entirely different display system, incompatible with MDA hardware but (mostly) compatible with PC software... http://Hardware.e-articles.info/title/History-of-display-adapters/ http://Hardware.e-articles.info/title/History-of-display-adapters/ Mon, 14 Jun 2010 10:31:20 GMT A mouse or other pointing device makes putting an original drawing into your a PC easy. But when you have an existing drawing or photograph that you want to convert into electronic form, the time it takes to manipulate a pointing device makes the effort seem pointless-particularly when there's a more expedient alternative. The best way to capture images into your PC is the scanner. The scanner can convert anything you have on paper-or, for that matter, anything reasonably flat-into computer-compatible electronic form... http://Hardware.e-articles.info/title/Types-of-Scanners/ http://Hardware.e-articles.info/title/Types-of-Scanners/ Mon, 14 Jun 2010 11:39:25 GMT Sometimes what you want to do with your computer is so obvious you could just point at the screen. If only you could move things around by pointing at them you would have instant, easy control. A light pen enables you to do exactly that. Shaped like a pen but trailing a cord, the light pen lets your computer register positions on the screen by your pointing at them... http://Hardware.e-articles.info/title/Light-Pens/ http://Hardware.e-articles.info/title/Light-Pens/ Mon, 14 Jun 2010 12:47:30 GMT With the development of three-dimensional applications-admittedly mostly games-your PC requires a level of control that mice and their derivatives cannot reach. Living only in the flat land of two dimensions, mice can only aspire to go higher or lower. They have no means of detecting your desire to move from simple X and Y co-ordinates into the Z dimension. What you need is an entirely new class of input device called the 3D controller... http://Hardware.e-articles.info/title/3D-Controllers/ http://Hardware.e-articles.info/title/3D-Controllers/ Mon, 14 Jun 2010 13:55:35 GMT To communicate its codes to your computer, the mouse must be connected in some way. Mice connect with PCs through any of three ways: a serial port, a built-in dedicated mouse port; or a special adapter that plugs into an expansion slot. Mice that use these methods are called (respectively) serial mice, proprietary mice, and bus mice. Serial Mice Most mice adapt to a port that is generally available-the standard serial port... http://Hardware.e-articles.info/title/Mouse-Connection-Interfaces/ http://Hardware.e-articles.info/title/Mouse-Connection-Interfaces/ Mon, 14 Jun 2010 14:23:40 GMT The most familiar challenger to QWERTY, one that crawls in a distant second in popularity and use, is the Dvorak-Dealey letter arrangement, named for its developers, August Dvorak and William L.

Anyone new to typing will be amazed and perplexed at the seemingly nonsensical arrangement of letters on the keys of the typical computer keyboard. Even the name given to this esoteric layout has the ring of some kind of black magic or odd cabala-QWERTY.
