A quadrilateral is a shape with four sides. A parallelogram is a quadrilateral that has two pairs of parallel sides (i.e. the sides opposite each other are parallel). A rectangle, for example, is a parallelogram. A trapezoid, however, is an example of a quadrilateral that is not a parallelogram - it has four sides, but only two of them are parallel to each other.

Is a octagon a quadrilateral and a parallelogram?
An octagon is neither a quadrilateral nor a parallelogram. "Quadrilateral" refers to a shape that has four sides. "Parallelogram" refers to a shape that has two pairs of opposite, congruent sides. An octagon has eight sides, and since eight is not equal to four, an octagon is neither a quadrilateral nor a parallelogram.
What shape has 4 sides that are not equal?
