PHP is short for Hypertext Pre-processor. It is a open source, server-side, HTML-embedded scripting language that lets you create dynamic Web pages. It is usually used to connect databases to Web sites. Pages using PHP end with a .php file extension rather than the .htm extension used in HTML pages

Digital Zoom is a fake zoom which creates a zooming effect by enlarging the pixels in the image on-the-fly. This type of zooming degrades the quality of the image, making it pixelated and unclear. On the other hand, optical zoom is achieved through lenses and, hence, is a lot more clearer and refined

DVI means Digital Visual Interface. A connection standard developed to connect computers to digital monitors such as flat panels and digital projectors. These connectors offer better colour and pictures as compared to older counterparts

CMYK is an abbreviation for cyan, magenta, yellow and key (black) – the four colours that form the ink-sets of many photo-quality printers. When combined together in varying proportions, CMYK can be made to produce the full colour spectrum. Some printers use six ink colours to achieve smoother, more photographic prints. The two additional colours are often lighter shades of cyan and magenta.

Thin Client is a stripped down PC designed specifically to be a “dumb terminal” in a client/server network. These terminals tend to cost less than fully-equipped computers especially since it uses software from – and processing power of – a remote server. Thin clients have no need for full software or internal devices of its own.
