An oxidizing agent (also called an oxidant, oxidizer or oxidiser) can be defined as a substance that removes electrons from another reactant in a redox chemical reaction. The oxidizing agent is "reduced" by taking electrons onto itself and the reactant is "oxidized" by having its electrons taken away. Oxygen is the prime example of an oxidizing agent, but it is only one among many.

Oxidation is a process in which exchange of electrons takes place from one reaction to another.

What did you say oxidation-reduction or redox? The loss of electrons is oxidation.
