But hardware alone is inert. The true intelligence lies in the —the software layer that translates the operating system's generic requests into specific commands the hardware understands.

In modern computing, the Peripheral Component Interconnect (PCI) bus is the circulatory system of the motherboard. From GPUs and NVMe SSDs to network adapters and sound cards, almost every high-speed peripheral relies on PCI or its derivatives (PCIe).
