HW401: Final Quiz: Understanding How It All Goes Together

1.What is the first step in a good PC design?

Gather user needs, constraints, budget, workloads, and support expectations.Choose the highest wattage PSU so every later part is covered by default.Select the newest CPU family before checking socket, memory, or workload needs.Pick the case first and adapt performance goals to the enclosure.

2.What is the best definition of a balanced build?

A system that solves the target workload while preserving compatibility, reliability, power, cooling, and budget discipline.A system that prioritizes future upgrades even if the current workload is underspecified.A system that maximizes peak performance before checking noise, thermals, and serviceability.A system that spends most of the budget on the part with the largest benchmark gain.

3.What should a handoff record include?

A case photo and the final price without firmware or validation details.Parts, settings, firmware, drivers, test results, warranty notes, limits, and maintenance advice.The graphics card model and a note that the system reached the desktop.Warranty notes, because settings and drivers can be rediscovered later.

4.What does a compatibility matrix help catch?

Benchmark bottlenecks discovered after final assembly.Price and availability conflicts without needing physical or electrical checks.Brand-family differences that matter more than fit, power, or firmware support.Cross-part issues such as socket, firmware, memory, lanes, fit, power, cooling, and headers.

5.Why validate with the user workload?

The named apps, games, displays, network, thermals, and storage behavior are what the build was designed to support.Workload validation is mainly for servers and not for client PC design.An idle synthetic check is a stronger acceptance test than the user's actual tasks.The desktop reaching idle proves editing, gaming, thermals, and network behavior.
