What measure of Hz is best in computers?

In computers, the best measure of Hz typically depends on the context. For CPU performance, clock speed, measured in gigahertz (GHz), indicates how many cycles per second the processor can execute, with higher values generally indicating better performance. For displays, refresh rates measured in hertz (Hz) determine how many times per second the screen updates, with higher refresh rates (like 60Hz, 120Hz, or 240Hz) providing smoother visuals. Ultimately, the "best" measure varies based on whether you're focusing on processing power or display quality.
