Origin of 'GHz'
Main points about word origin
- The term 'Giga' comes from a Greek word meaning 'giant', while 'Hertz' is named after Heinrich Hertz, a scientist who studied waves.
- 1 GHz equals 1 billion hertz, highlighting its measurement of frequency, or how often something happens.
- The abbreviation 'GHz' reflects a specific standard of measurement in technology, commonly used for CPU speeds.
The term GHz stems from the term 'hertz,' which is named after the German physicist Heinrich Rudolf Hertz, who made significant contributions to the understanding of electromagnetic waves. The 'giga-' prefix, meaning billion, is derived from the Greek word 'gigas,' which means giant. Originally, the hertz was defined in 1930 and has since become the standard unit of frequency in the International System of Units (SI). Growth in technology and telecommunications increased the relevance of the GHz unit, especially as microprocessors advanced in speed and capability, moving from megahertz (MHz) to gigahertz. By the late 1990s and early 2000s, GHz became commonplace in the specifications for computer processors and mobile technology, highlighting the rapid pace of development in these sectors.
