The terms "3-wire" and "4-wire" are often used to describe the electrical system design. The term 3-wire means that there are three "hot" conductors, line 1, 2, and 3 shown in Figure 2. While the term 4-wire means that in addition to three "hot" conductors there is a fourth "neutral" conductor.

The boot process

The Linux boot process follows the general booting model. The flow of control during a boot is from BIOS, to multi-stage boot loader, to kernel. When PC is powered up and the BIOS is loaded and a boot device is found, the first-stage boot loader is loaded into RAM and executed. This boot loader as we seen is less than 512 bytes in length, and.
