Essential Question:

Which hardware subsystems matter most for system stability and performance, and how can a technician diagnose failures accurately?

🎯 Learning Intention

I will identify and explain the most critical Core 1 hardware concepts: motherboards, RAM, storage, power systems, cooling, and the boot process.

✅ Success Criteria

• I can describe how major hardware subsystems work.
• I can connect system symptoms to the correct failing component.
• I can explain the difference between RAM, CPU, GPU, and storage bottlenecks.
• I can describe how the BIOS/UEFI and POST influence system startup.

📚 Vocabulary (Students Copy)

Chipset — The motherboard logic that manages data lanes, memory, and storage.

VRM (Voltage Regulator Module) — Controls clean power delivery to CPU/RAM.

Dual Channel — RAM paired to double memory bandwidth.

Latency (CL) — Delay before RAM returns data to the CPU.

PCIe Lane — Highway for high-speed devices like NVMe and GPUs.

NVMe — Fast PCIe-based storage for SSDs.
