  • 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.

  • ecclesiastical calendar — a calendar based on the lunisolar cycle, used by many Christian churches in determining the dates for the movable feasts.
  • electronic mail address — (messaging)   (Usually "e-mail address") The string used to specify the source or destination of an electronic mail message. E.g. "[email protected]". The RFC 822 standard is probably the most widely used on the Internet. X.400 was once used in Europe and Canada. UUCP-style (bang path) addresses or other kinds of source route became virtually extinct in the 1990s. In the example above, "john" is the local part which is the name of a mailbox on the destination computer. If the sender and recipient use the same computer, or the same LAN, for electronic mail then the local part is usually all that is required. If they use different computers, e.g. they work at different companies or use different Internet service providers, then the "host part", e.g. "sales.acme.com" must be appended after an "@". This usually takes the form of a fully qualified domain name or, within a large organisation, it may be just the hostname part, e.g. "sales". The destination computer named by the host part is usually a server of some kind rather than an individual's workstation or PC. The user's mail is stored on the server and read later via client mail software running on the user's computer. Large organisations, such as universities will often set up a global alias directory which maps a simple user name such as "jsmith" to an address which contains more information such as "[email protected]". This hides the detailed knowledge of where the message will be delivered from the sender, making it much easier to redirect mail if a user leaves or moves to a different department for example.
  • encapsulated postscript — (EPS) An extension of the PostScript graphics file format developed by Adobe Systems. EPS is used for PostScript graphics files that are to be incorporated into other documents. An EPS file includes pragmas (special PostScript comments) giving information such as the bounding box, page number and fonts used. On some computers, EPS files include a low resolution version of the PostScript image. On the Macintosh this is in PICT format, while on the IBM PC it is in TIFF or Microsoft Windows metafile format.
