Hardware — CompTIA A+ Core 1 (220-1101) Practice Questions

Hardware knowledge is central to the CompTIA A+ Core 1 exam, spanning CPUs, RAM, storage devices, motherboards, power supplies, expansion cards, and peripheral devices. Candidates are expected to identify components by sight, understand their specifications and compatibility requirements, and perform installations, upgrades, and replacements correctly. The exam tests both conceptual knowledge, such as understanding CPU socket types and memory channel configurations, and practical skills like following ESD precautions and reading component specifications. A solid grasp of hardware fundamentals underpins nearly every other topic on the Core 1 exam.
