At its core, the focus of a parabola is the point on the curve that is equidistant from the directrix and the vertex. The vertex is the point on the parabola that is the lowest or highest point, depending on the direction of the parabola. The focus and vertex are connected through the concept of eccentricity, which measures how stretched or compressed the parabola is. The closer the focus is to the vertex, the more eccentric the parabola is.
