About this quiz
What you’ll practice
Match common PC components to their core jobs, like processing, memory, storage, power delivery, and connectivity. You’ll also get comfortable with everyday terms used in troubleshooting and upgrades.
Each question is multiple-choice with 4 options and there’s no timer, so you can think through the role of each part without rushing.
Common pitfalls to watch for
New learners often mix up RAM vs storage, or assume the motherboard “does the computing” instead of connecting and coordinating parts. Another frequent slip is confusing integrated vs dedicated components (like graphics) and what actually affects performance.
- RAM is short-term working memory; SSD/HDD is long-term storage
- The CPU executes instructions; the GPU focuses on graphics/parallel workloads
- The motherboard connects components; it doesn’t replace the CPU or RAM
- The PSU supplies power; it doesn’t improve speed by itself
- Ports and expansion slots determine connectivity and upgrade options
