Explanation:
Detailed explanation-1: -One gigahertz represents 1 billion cycles per second. Clock speed, which is also measured in hertz, refers to synchronous circuit clock frequency, for example, a CPU.
Detailed explanation-2: -A CPU with a clock speed of 3.2 GHz executes 3.2 billion cycles per second. (Older CPUs had speeds measured in megahertz, or millions of cycles per second.) Sometimes, multiple instructions are completed in a single clock cycle; in other cases, one instruction might be handled over multiple clock cycles.
