Episode 10 — Hardware discovery mindset: CPU, memory, devices, and what looks wrong
Linux+ expects you to reason about hardware through the lens of symptoms and system reports, not through brand-specific knowledge. This episode teaches a hardware discovery mindset: start with what the OS believes is present, compare it to what should be present, then ask whether the discrepancy is detection, driver, configuration, or resource exhaustion. You’ll focus on the core categories tested most often—CPU, memory, storage, and peripheral devices—and how each category “tells on itself” in typical outputs. The objective is to help you quickly recognize what looks wrong, such as a CPU feature mismatch affecting virtualization, memory pressure masquerading as random crashes, or devices that appear but fail due to missing firmware or permissions.
we translate that mindset into exam-style troubleshooting sequences and practical guardrails. You’ll learn to separate discovery (what the system sees) from capability (what it can use) and from performance (whether it’s healthy under load), because these are different questions with different evidence. We cover scenarios like “new NIC installed but no interface shows up,” “disk present but not mountable,” and “GPU available but no acceleration,” and we emphasize minimal-change testing to avoid making the system less stable while you diagnose. Finally, we connect hardware discovery to change control: recording baselines, validating after kernel or driver updates, and knowing when a symptom points to physical failure rather than software misconfiguration.
