A Programmable Interrupt Controller (PIC) is a interrupt controller that manages interrupt signals received from devices by combining multiple interrupts into a single interrupt output. PIC is found on most PCs today. One of the most well-known Programmable Interrupt Controllers is Intel 8259A, which was included in the x86 PC as a part of the motherboard chipset.
