Answer 2

Vibration and oscillatiion is almost synonyms.
But for example a harmonic oscillator is just one type of vibration.
@UnkleRhaukus care to elaborate/correct?

Answer 3

Or as my professor would say to me:
"The oscillation ω (f, A) is a measure of how much function values ​​vary over the subset A of the definition area. This is defined as the smallest number m satisfying the inequality | f (x) f (y) | ≤ m for all x, y from A. To a function f of a real variable is continuous at x = a, can be expressed as, the oscillation ω (f,] a-δ, a + δ [) has the limit 0 when δ approaches 0"
