Detailed explanation-1: -Clock speed is expressed in gigahertz-billions of cycles per second.
Detailed explanation-2: -The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz). A “cycle” is technically a pulse synchronized by an internal oscillator, but for our purposes, they’re a basic unit that helps understand a CPU’s speed.
Detailed explanation-3: -Generally speaking, the higher number of pulses per second, the faster the computer processor will be able to process information. The clock speed is measured in Hz, typically either megahertz (MHz) or gigahertz (GHz). For example, a 4GHz processor performs 4, 000, 000, 000 clock cycles per second.
Detailed explanation-4: -One clock cycle is 1 / ( 1 * 10^6 cycles/sec. ) or 1/1 * 1/(10^6 cycles/sec). 1 over a power flips the units and the sign is inverted, so 1/10^6 cycles/sec becomes 10^-6 secs/cycle.
Detailed explanation-5: -The unit of measurement called a hertz (Hz), which is technically one cycle per second, is used to measure clock speed. In the case of computer clock speed, one hertz equals one tick per second. The clock speed of computers is usually measured in megahertz (MHz) or gigahertz (GHz).
