What unit is GHz an abbreviation for?

Gigahertz is a unit of frequency that measures the number of cycles per second in a periodic signal. The prefix "giga-" denotes a factor of one billion (1,000,000,000), while "hertz" (Hz) is the basic unit of frequency in the International System of Units (SI), representing one cycle per second. Therefore, one gigahertz equates to one billion cycles per second. This unit is commonly used to express the clock speed of processors, indicating how many operations they can perform in one second, and is significant in the context of computing and electronics. The use of "gigahertz" in technology highlights the importance of speed and performance in modern digital systems.
