2. What is PC104? 

PC104 (or PC/104) is an embedded computer standard by the PC104 Consortium, that defines both a form factor and computer bus. Unlike the popular ATX form factor and PCI computer bus currently used for most PC's, PC104 is intended for specialized uses, such as for a data acquisition or industrial control system. This form factor does not have a backplane, instead components come in modules that are stacked one atop another. The standard size is 3.55 × 3.75 inches (90.17 mm × 95.89 mm), and the height depends on the height of the individual modules and the number of modules connected. A typical installation includes a motherboard, analog-to-digital converter, and digital I/O module.

The 1992 PC104 computer bus utilizes 104 pins. These pins include all the normal lines used in the ISA bus, with additional ground pins added to ensure bus integrity. Signal timing and voltage levels are identical to the ISA bus, with lower amperage requirements.
