What is PCIe?

PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard, designed to replace the older PCI, PCI-X, and AGP bus standards. It's commonly used for connecting graphics cards, network cards, storage interfaces (like NVMe SSDs), and other high-performance peripherals to a computer's motherboard.
