An Advanced Programmable Interrupt Controller (APIC) is a more intricate Programmable Interrupt Controller (PIC) containing a magnitude more outputs and much more complex priority schemas.
One of the best known APIC architectures, the Intel APIC Architecture, is now replacing the original 8259A PIC in newer x86 PCs.

When working with computer hardware, installing and removinge devices, the system relies on Interrupt Requests (IRQ). There are default settings that are configured in the system BIOS and recognized by the operating system. These default settings can be altered by advanced users. Modern Plug and Play technology has not only reduced the need for concern for these settings, but has virtually eliminated manual configuration.
