x86



The definition of x86

The x86 series of processors includes the Pentium, Pentium Pro, Pentium II, Pentium III, Celeron, and Athlon as well as the 786, 686, 586, 486, 386, 286, 8086, 8088, etc. It is an exceptionally popular design (by far the most popular CISC series) in spite of the fact that even its fastest model is significantly slower than the assorted RISC processors. Many different OSes run on machines built around x86 processors, including MS-DOS, Windows 3.1, Windows '95, Windows '98, Windows ME, Windows NT, Windows 2000, Windows CE, Windows XP, GEOS, Linux, Solaris, OpenBSD, NetBSD, FreeBSD, Mac OS X, OS/2, BeOS, CP/M, etc. A couple different companies produce x86 processors, but the bulk of them are produced by Intel. It is expected that this processor will eventually be completely replaced by the Merced, but the Merced development schedule is somewhat behind. Also, it should be noted that the Pentium III processor has stirred some controversy by including a "fingerprint" that will enable individual computer usage of web pages etc. to be accurately tracked.
