What is GHz?
Gigahertz, generally abbreviated GHz, refers to frequencies in the billions of cycles per second range. Giga is the standard multiplier for 1 billion, and Hertz is the standard unit for measuring frequencies, expressed as cycles or occurrences per second. One GHz is equivalent to one thousand megahertz (MHz). GHz is commonly used when discussing computer performance or radio frequencies. In computers, GHz most often refers to the clock speed of the central processing unit, or CPU; the faster the CPU clock can tick, the faster, in general, the computer can process data and instructions. In 2000, Intel and Advanced Micro Devices achieved a marketing and technical milestone by releasing the first CPUs to run at 1 GHz. Speeds have subsequently reached 4 GHz. In radio communications, GHz is used to define bands of the electromagnetic spectrum. Different bands will be assigned different uses. S-Band, for example, is a band of spectrum between 2 and 4 GHz. Common technologies such as Bluetoot
