  • differential weathering — the difference in degree of discoloration, disintegration, etc., of rocks of different kinds exposed to the same environment.
  • digital subscriber line — (communications, protocol)   (DSL, or Digital Subscriber Loop, xDSL - see below) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and telephone companies. When two conventional modems are connected through the telephone system (PSTN), it treats the communication the same as voice conversations. This has the advantage that there is no investment required from the telephone company (telco) but the disadvantage is that the bandwidth available for the communication is the same as that available for voice conversations, usually 64 kb/s (DS0) at most. The twisted-pair copper cables into individual homes or offices can usually carry significantly more than 64 kb/s but the telco needs to handle the signal as digital rather than analog. There are many implementation of the basic scheme, differing in the communication protocol used and providing varying service levels. The throughput of the communication can be anything from about 128 kb/s to over 8 Mb/s, the communication can be either symmetric or asymmetric (i.e. the available bandwidth may or may not be the same upstream and downstream). Equipment prices and service fees also vary considerably. The first technology based on DSL was ISDN, although ISDN is not often recognised as such nowadays. Since then a large number of other protocols have been developed, collectively referred to as xDSL, including HDSL, SDSL, ADSL, and VDSL. As yet none of these have reached very wide deployment but wider deployment is expected for 1998-1999.

  • extended graphics array — (hardware)   (XGA) An IBM display standard introduced in 1990. XGA supports a resolution of 1024 x 768 pixels with a palette of 256 colours, or 640 x 480 with high colour (16 bits per pixel). XGA-2 added 1024 x 768 support for high colour and higher refresh rates, improved performance, and supports 1360 x 1024 in 16 colours. XGA is probably not the same as 8514-A. See also VESA's EVGA released at a similar time.

  • garbage in, garbage out — (humour)   (GIGO) /gi:'goh/ Wilf Hey's maxim expressing the fact that computers, unlike humans, will unquestioningly process nonsensical input data and produce nonsensical output. Of course a properly written program will reject input data that is obviously erroneous but such checking is not always easy to specify and is tedious to write. GIGO is usually said in response to lusers who complain that a program didn't "do the right thing" when given imperfect input or otherwise mistreated in some way. Also commonly used to describe failures in human decision making due to faulty, incomplete, or imprecise data. The expansion "Garbage In, Gospel Out" is an ironic comment on the tendency to put excessive trust in "computerised" data.

It provides an abstraction to save programmers from dealing with the detailed capabilities and interfaces of specific hardware. GKS defines a basic two-dimensional graphics system with: uniform input and output primitives; a uniform interface to and from a GKS metafile for storing and transferring graphics information. It supports a wide range of graphics output devices including such as printers, plotters, vector graphics devices, storage tubes, refresh displays, raster displays, and microfilm recorders.
