big-endian

1.	(data, architecture)	big-endian - A computer architecture in which, within a given multi-byte numeric representation, the most significant byte has the lowest address (the word is stored "big-end-first"). Most processors, including the IBM 370 family, the PDP-10, the Motorola microprocessor families, and most of the various RISC designs current in mid-1993, are big-endian. See -endian.
2.	(networking, standard)	big-endian - A backward electronic mail address. The world now follows the Internet hostname standard (see FQDN) and writes e-mail addresses starting with the name of the computer and ending up with the country code (e.g. fred@doc.acme.ac.uk). In the United Kingdom the Joint Networking Team decided to do it the other way round (e.g. me@uk.ac.wigan.cs) before the Internet domain standard was established. Most gateway sites required ad-hockery in their mailers to handle this. By July 1994 this parochial idiosyncracy was on the way out and mailers started to reject big-endian addresses. By about 1996, people would look at you strangely if you suggested such a bizarre thing might ever have existed.
