An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron

In simple and easy way ,

Redox reaction is the sum of both oxidation and reduction !

Where ever both are taking place , you should call that redox reaction !
