How much more energy does a PC require compared to thin client?

The correct answer is A. 15 to 20 times more. A traditional PC consumes roughly 15 to 20 times more energy than a thin client (option A) because a PC houses its own full CPU, GPU, hard drive, RAM, and cooling system, while a thin client offloads most processing to a central server and uses minimal local hardware. Options B…

Explanation

A traditional PC consumes roughly 15 to 20 times more energy than a thin client (option A) because a PC houses its own full CPU, GPU, hard drive, RAM, and cooling system, while a thin client offloads most processing to a central server and uses minimal local hardware. Options B (5–10x) and C (2–5x) underestimate this gap - those ranges might describe differences between a laptop and a thin client, or between energy-efficient desktop variants. Option D (10–15x) is closer but still falls short of the documented real-world differential.

Memory tip: Think of a thin client as a "dumb terminal" - it's essentially just a screen and keyboard with a network card, so compared to a full PC it's almost like comparing a light bulb to a refrigerator in power draw. The extreme ratio (15–20x) signals you should pick the highest multiplier option on the exam.
