Question 1

What is CPU frequency measured in?

Accepted Answer

Gigahertz (GHz). 1 GHz = 1 billion cycles per second. Modern CPUs: 2-5 GHz base, higher boost.

Question 2

What is CPU turbo boost?

Accepted Answer

Temporary higher frequency when thermal/power headroom allows. Intel: Turbo Boost. AMD: Precision Boost.

Question 3

What's the relationship between frequency and wavelength?

Accepted Answer

They're inversely related: wavelength × frequency = wave speed. For sound in air: wavelength (m) ≈ 343 / frequency (Hz).

Question 4

Why use Hz vs RPM?

Accepted Answer

Hz (cycles per second) is universal for waves and oscillations. RPM (revolutions per minute) is more intuitive for rotating machinery and engines.
