     The more processors an operating system runs on, the more variety of choices of vendors and the greater the scale (large to small systems) available. LINUX is the “king” of variety, running on almost every processor made.

     “NetBSD will run on practically anything: DEC Alpha, Motorola 68k (Amiga, Atari, Mac, MVME, Sharp, Sun3), PowerPC, Intel, DEC VAX, Acorn RISC, MIPS (Sony NEWS, DECstation), etc. Linux is most popular and will run on a wide range hardware: Sun, Intel, DEC Alpha, PowerPC, PowerMac, etc.” —“Microsoft Windows NT Server 4.0 versus UNIX”^w51

     Note that just because an operating system runs on a particular processor, it does not necessarily mean that it runs on every computer model that uses that processor. The “devil is in the details”. Not all operating systems run well on multiple platforms. As an example, Microsoft ported their Windows NT operating system to several different processors in a highly publicized move to demonstrate their cross-platform capabilities, but then quietly dropped some platforms and has poorly supported any platform other than the Intel Pentium (I won’t get into debates about the criticism that Windows NT doesn’t run well on its main platform either).

    The main advantage of using just one operating system throughout an organization is increased compatibility and increased uniformity. This should (but doesn’t always) reduce training costs, reduce support costs, and increase group productivity.

    In practice, the same operating system does not always work the same on different hardware platforms. Often there is a great variance in the quality of the implementation across different hardware and sometimes different feature sets are available. Also, software written for a particular operating system is not always available on every hardware platform that OS runs on.

     “Most potential customers feel better about running their Windows applications on 100 percent Wintel-compatible machines, even if it means running them slower than they might run on an Alpha, MIPS, or some other platform.

    “As a result, non-Intel platforms fell away as Windows NT progressed, leaving only the Alpha version of Windows NT as an emotionally viable non-Intel platform (though even interest in the Alpha remains limited, despite its superior performance). By promoting cross-platform support, Microsoft was competing with the very concept that led to its widespread success.” —Nicholas Petreley, “The new Unix alters NT’s orbit”, NC World^w74

    Some organizations thrive on a mixed operating system environment. Each operating system/hardware combination has its own unique set of advantages and disadvantages. There is no such thing as a universal “best” for all applications.

     A classic example is that many Windows-only organizations make an exception for content creation machines, which are usually Macintoshes.

     Another classic example is high end animation and motion picture special effects, where a combination of Windows/Intel, Apple Macintosh, SGI IRIX/MIPS, Sun Solaris/SPARC, and DEC Alpha machines is common, each doing key parts of the total job.

    In a mixed operating system environment, connectivity becomes extremely important.

    It does not matter if an operating system runs on processors you never intend to use. The most common desktop processors are the Pentium and the PowerPC. The most common high end server processors are the SPARC, Alpha, HP-RISC, and MIPS.
