Correct answer: B

The processing power of a CPU is not just about how fast it "thinks," but also how much data it can handle at once and how much memory it can access.

  1. Data Bus Width: This determines how many bits of data the CPU can move in a single cycle. A 64-bit data bus can move twice as much data as a 32-bit bus, directly increasing throughput.

  2. Clock Speed: This is the frequency at which a processor executes instructions. A higher clock speed (measured in GHz) means the CPU can perform more operations per second.

  3. Address Bus Width: This determines the maximum amount of RAM the CPU can address (use). If the address bus is too narrow, the CPU is limited in the amount of memory it can utilize, which can create a bottleneck for data-heavy processing tasks.
