PCI Express

PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe, is a high-speed standard used to connect hardware components inside computers. It is designed to replace older expansion bus standards such as PCI, PCI-X and AGP. Developed and maintained by the PCI-SIG (PCI Special Interest Group), PCIe is commonly used to connect…
