The term GHz is an indicator of which feature of the computer?

- Gigahertz is a measurement of something happening X times per second. - 4 gigahertz means that the thing is happening 4 billion times a second. When we say that the processor runs at 4ghz we mean that the main clock of the processor is ticking 4 billion times per second. - CPUs are digital circuits. They only do an action when the clock drives the circuit to do the action. Think of that as the RPM of a car. The faster the clock goes, the faster the actions happen. - For performance, clock speed is important but its not directly comparable between different CPU architectures. Clock speeds are comparable only in the same family of cpus that share an architecture.
