What is GHz and MHz?

Answer 1

MHz stands for Mega Hertz.

Hertz or Hz is unit for frequency and is represented by inverse of time unit i.e. second(-1) i.e. 1/second or per second.

Frequency = 1/ time period in seconds

1MHz is 10^6 or 1000000 Hz.

Answer 2

MHz stands for Mega Hertz, which is 1 million cycles per second or Hertz. Hertz is a unit of frequency which is inverse of time (/second or per second). In case of digital electronics or computing, it denotes the speed or frequency of clock at which a device or an interface operates.

Answer 3

one GHz = 1000 MHz

Hz are cycles per second
