This course launches the CompTIA A+ Core 1 Specialization by building the foundational hardware knowledge every IT technician must have. Covering approximately 4 hours of expert instruction across the A+ exam overview, safety and professionalism, CPUs, and memory, learners develop the skills to work confidently inside any desktop or workstation. Learners benefit by gaining hands-on understanding of how processors are selected and installed, how RAM is identified and configured, and how safety procedures protect both the technician and the equipment. Online labs reinforce CPU identification, RAM installation, and component handling. This course provides the physical foundation on which all subsequent IT skills are built. By the end of this course, learners will be able to identify, install, and handle core PC components safely in a professional IT support context.
