PCI and Device Management

PCI (Peripheral Component Interconnect) is a standard local computer bus for attaching hardware devices, or peripherals, to a computer's motherboard. Device management is the process by which an operating system (OS) interacts with this hardware, beginning with the enumeration phase where the OS scans the PCI bus to discover all connected devices. Following discovery, the OS configures each device by allocating necessary system resources like memory address ranges, I/O ports, and interrupt request (IRQ) lines. Finally, the OS loads the appropriate device driver—a specialized piece of software—that enables communication between the OS and the hardware, making the peripheral's functionality accessible to applications and the user.
