Many computers do not look like desktop PCs simply because you cannot see them at all. These invisible computers are hidden—or “embedded”—within a larger system or product. Embedded computers provide better control for a larger system. The components of many embedded computers fit on a single printed circuit board, making an embedded computer compact and economical.

The stringent real-world, real-time requirements of control applications mean that the hardware and software of embedded computers are distinctly different from ordinary desktop PCs. What follows is a discussion on the various hardware and software features that Z-World controllers provide.
