"Web2.4 Ordinary Interpolation. Interpolation is any procedure for fitting a function to a set of points in such a manner that the function intercepts each of the points. Consider m points ( x[k], y[k]) where x[k] n, y[k] , and the x[k] are distinct. We wish to construct a function f : n → such that y[k] = f ( x[k]) for all k. " - Splines interpolation

Suppose you have n data items to interpolate (maybe n points, or n − 2 points and 2 end derivatives). Then we need a spline with n control points (and therefore n degrees of freedom). If a quadratic b-spline has n control points, then it must have n + 3 knots.
