Tech+ Lesson

CPU (Central Processing Unit): executes instructions for Tech+

Last updated: 6/10/2026

Short answer

CPU (Central Processing Unit): executes instructions. A computer's internal components each have specific roles: - Motherboard: Primary circuit board that holds and interconnects all components. Provides data pathways (buses) for components to communicate. - Firmware/BIOS/UEFI: Low-level software on a chip that initializes hardware at boot and provides configuration settings. - CPU: The "brain" that performs computations and runs program instructions. Modern CPUs have multiple cores and run at GHz speeds. - RAM: High-speed, volatile memory the CPU uses for active data and programs. Clears when power is off.

Why it appears on the exam

This lesson supports FC0-U71 2.0 on CompTIA Tech+ FC0-U71. The public page gives the basic concept for free; the app adds tracking, quizzes, and weak-area practice.

Concept 3

How to recognize it on Tech+

On FC0-U71, stay at beginner IT depth: identify when the question is asking about CPU (Central Processing Unit): executes instructions, then choose the basic concept or support action that matches the situation. Do not jump into advanced vendor administration unless the prompt clearly gives that scope.
