Morphology

bandwidth = band + width (semi-transparent) = band + width

The compound literally combines 'band' + 'width' (a width of a frequency band), but the technical sense 'data rate' requires domain knowledge and is not obvious to all learners.

Etymology

Bandwidth comes from joining band (a 'range' of radio waves or signals) and width ('how wide'). So it literally means the 'width' of that signal range — how much data can move at once, like how many cars fit on a road, which is why bandwidth measures how fast a connection can send data.
