PCIe (Peripheral Component Interconnect Express)

PCIe (Peripheral Component Interconnect Express) is a high-speed interface used inside computers to connect hardware components like graphics cards, SSDs, and network cards to the motherboard. It transfers data quickly and efficiently by using lanes—each comprising differential pairs for sending and receiving data—that can be combined for higher transfer speeds. PCIe offers fast communication, flexibility, and scalability, supporting modern demanding tasks such as gaming, video editing, and data processing. Its design enables hardware upgrades and improvements without needing to replace the entire system, making it a crucial technology for modern computing performance.
