RF & MW difference

is that upto 1GHz is RF and from 1 GHz to 30 GHz is microwave

what is the difference between them.
or both are same to reperesent the range of frequency.

is that microwave name came because of it wavelength? if so most of the wavelength in microwave frequency are not in micro wavelength.

Pls explain me.

mw mainly use distrubutited element, espcially passive element.
RF mainly use lump element.

There is no strict differences betweem them,
but microwave if more wideband for frequences

Maybe you can follow the upstairs' opinion

Interestingly most microcomputers are also not micron sized

anyways you can consider 'micro' as an adjective here, not necessarily a scientific prefix..

RF stands for "radio frequency" so basically microwave, or any other frequency above audio and ultrasound range is RF (approx. 100kHz and above).
