What you learn in Theory:
Bandwidth is the difference between the upper and lower frequencies in a continuous set of frequencies.
What you learn in Practice:
A key characteristic of bandwidth is that any band of a given width can carry the same amount of information, regardless of where that band is located in the frequency spectrum.
