Though checking your computer's RAM speed is incredibly simple, Mac and PC have the information located in different places.

Frequencies are in kiloHertz (kHz). 1 MegaHertz (MHz) is equal to 1000 kHz. Conversion to meter bands: Meters=300000/frequency in kHz. e.g.: 17705 kHz --> 16.9 meters ...

For water waves and sound waves the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz (\(MHz\)) are better units.

Most modern wired LANs use CAT6 cabling that allows connection speeds of up to 250 megahertz (MHz). Wireless connections use radio waves to carry signals. These signals are limited in range ...
