Hertz (SI Frequency Unit)

Introduction : The hertz is the SI unit of frequency, representing one cycle per second. It measures periodic events like sound waves, radio signals, and processor clock speeds. Named after physicist Heinrich Hertz, it's fundamental in physics and engineering.

History & Origin : Introduced in 1930 by the International Electrotechnical Commission (IEC) to replace 'cycles per second.' Named after Heinrich Hertz, who proved electromagnetic wave existence in 1886. Adopted as the SI unit in 1960.

Current Use : Used in audio engineering (20 Hz–20 kHz human hearing), radio broadcasting (kHz–MHz), and computing (CPU clock speeds in GHz). Essential for measuring vibrations, light frequencies, and alternating current (AC) electricity.

Gigahertz (Billion Hertz)

Introduction : Representing a billion cycles per second, gigahertz defines modern computing and microwave communications. It's the standard for processor speeds and 5G networks.

History & Origin : Entered common usage in the 1990s with GHz-range CPUs (Intel Pentium). Microwave technology and satellite communications pushed GHz frequencies into mainstream use.

Current Use : Critical for CPU/GPU clock speeds (e.g., 3.5 GHz processors), 5G/4G cellular networks (1–6 GHz), and radar systems. Microwave ovens operate at 2.45 GHz.
