What does MHz stand for?

• A. Megabyte
• B. Megabit
• C. Mbps
• D. Megahertz

Answer: (D)

Frequency units describe how often something repeats per second. MHz stands for megahertz, a unit that measures cycles per second. “Mega” means one million, so one megahertz equals one million hertz—one million cycles each second. This is used to describe how fast something like a CPU clock or radio signals oscillate. It isn’t a data size (megabyte) and isn’t a data rate (megabits per second or Mbps). So MHz refers to frequency, not amount of data or its throughput. For example, a 2.4 GHz processor runs at about 2,400,000,000 cycles per second, which is 2,400 MHz.
