gigahertz

[หŒษกษชษกษ™หˆhษœหrts ]

Definition

Context #1 | Noun

frequency measurement

Gigahertz (GHz) is a unit of frequency equivalent to one billion hertz. It is commonly used to measure the frequency of electromagnetic waves, such as radio and microwaves, as well as the clock speed of computer processors. In computing, a processor operating at a specific gigahertz value can perform a certain number of cycles per second, influencing its performance. Higher gigahertz values generally indicate faster processing speeds, but other factors contribute to overall performance. This unit is part of the metric system and is denoted by the prefix 'giga', which means billion.

Synonyms

GHz, frequency, megahertz.

Examples of usage

  • My computer's processor runs at 3.5 gigahertz.
  • The Wi-Fi network operates on a 5 gigahertz frequency.
  • Some modern smartphones have processors that exceed 2.0 gigahertz.
  • The signal strength improves at the gigahertz level.

Origin of 'gigahertz'

Main points about word origin

  • The term 'gigahertz' combines 'giga', meaning billion, and 'hertz', named after Heinrich Hertz, a pioneer in the study of electromagnetism.
  • The first use of 'hertz' as a measure was in the 1930s, and it quickly became standard in describing frequencies after being named in 1960.

The term 'gigahertz' comes from the combination of 'giga' and 'hertz'. 'Giga' is a prefix in the metric system denoting a factor of one billion, derived from the Greek word 'gigas' meaning giant. 'Hertz' itself is named after the German physicist Heinrich Rudolf Hertz, who made important contributions to the study of electromagnetic waves in the late 19th century. The use of gigahertz as a unit of frequency became more prominent in the late 20th century with the advancements in technology, particularly in computing and telecommunications. As devices required faster processing speeds and higher frequency signals, the term gigahertz gained usage in everyday vocabulary, especially among tech enthusiasts and professionals.
