<jargon, architecture> A term describing any computer platform consisting of some version of Microsoft Windows running on an Intel 80x86 processor or compatible.
Despite the dominance of the wintel platform, in its many forms, from MS-DOS on an Intel 8088 to Windows 2000 on a Pentium II Xeon, there are many "non-wintel" platforms in use. These include Acorn, Amiga, Apple, ARM, Atari, A\Box, Be, Network Computer, OS/2, PowerPC, Psion, Linux and all other Unix systems.
