The speed of the CPU, measured in hertz (Hz), directly affects how quickly the computer can execute instructions and perform calculations. A faster CPU can process more instructions per second, leading to improved performance in running applications, handling tasks, and overall system responsiveness. This means that when you have a higher CPU speed, complex operations and processes can be completed more swiftly, enabling smoother multitasking and quicker loading times for software.

The other options relate to different aspects of computer performance and capabilities that are not directly tied to CPU speed. While quality software programs might require certain hardware specifications, they are not determined solely by CPU speed. Similarly, graphics capabilities are primarily influenced by the graphics processing unit (GPU), and the amount of data stored is dictated by storage devices like hard drives or SSDs rather than CPU performance.
