In summary, GHz and Hz are two units of measurement used to measure the frequency of clock signals. While GHz is used to measure signals in the range of 100 MHz to 100 GHz, Hz is used to measure signals in the range of 1 Hz to 100 kHz.
Frequency, measured in hertz (Hz), is the number of cycles per second that a system undergoes. In simpler terms, it is the speed at which a system oscillates or changes its state. This oscillation can refer to a wide range of phenomena, from the swinging of a pendulum to the oscillation of an electromagnetic wave.
The unit of measurement for frequency is named after Heinrich Hertz, a German physicist who first demonstrated the existence of electromagnetic waves. In the context of computing, frequency is often used to describe the speed at which a processor or other component of a computer system operates. For example, a processor with a clock speed of 3 GHz (gigahertz) oscillates 3 billion times per second, while a processor with a clock speed of 2 Hz oscillates 2 times per second.
In summary, Hz is a unit of measurement for frequency, which refers to the number of cycles per second that a system undergoes. In the context of computing, it is used to describe the speed at which a processor or other component of a computer system operates.
