Pcie — CompTIA A+ Core 1 (220-1101) Practice Questions
PCIe (Peripheral Component Interconnect Express) is the dominant high-speed interface used to connect expansion cards such as GPUs, NVMe SSDs, network adapters, and sound cards to a motherboard. The 220-1101 exam tests knowledge of PCIe slot sizes (x1, x4, x8, x16) and how lane count affects bandwidth, as well as PCIe generations (3.0, 4.0, 5.0) and their backward compatibility. Candidates must understand which slot is appropriate for a given card and how slot availability constrains build configurations. PCIe is foundational knowledge for installing and troubleshooting expansion hardware in both consumer and workstation systems.
