Parabola is represented by a line (its directrix) and a point (its focus). Points on parabola are then at same distance from directrix and focus. These parameters allows to define following properties :

parabola axis of symmetry is given by the line orthogonal to directrix and which passes through its focus.
parabola vertex is the point of the parabola which intersect the axis of symmetry, this is the most sharply curved parabola point and this is the mid point between focus and directrix.

Parabola parameters are illustrated on following image :
