What does PCIe stand for?

• A. Peripheral Component Interconnect Express
• B. Peripheral Component Interconnect Extension
• C. Personal Computer Interconnect Express
• D. Peripheral Input Controller Express

Answer: (A)

PCIe stands for Peripheral Component Interconnect Express. The term describes its role as the high-speed interconnect that links expansion cards and other peripherals to the motherboard. "Peripheral" refers to devices outside the core CPU/memory, "Component Interconnect" is the bus concept that connects those components, and "Express" signals its fast serial communication, replacing older parallel PCI schemes. The other phrases mix up the terminology: "Extension" isn’t part of the official name, "Personal Computer" isn’t how this bus is described, and "Input Controller" isn’t what PCIe represents. PCIe is the modern, versatile expansion bus used for GPUs, NICs, SSDs, and more, with lanes that scale bandwidth across generations.
