What is the difference and connection between the projection of force on the rectangular coordinate axis and the component of force along the rectangular coordinate

The component of force on two axes is vector, and the projection of force on the axis is scalar, which must be the same in rectangular coordinate system. The problem is that on two axes, that is rectangular coordinate system
