What is the meaning of the process Oxidation?

Here I've explained Oxidation and Reduction, and the difference between them.

Hope your all doubts will be cleared related to this topic.

Oxidation is the loss of electrons or an increase in the oxidation state of an atom, an ion, or of certain atoms in a molecule.

Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.

2Mg(s) + O2(g) ------------    2MgO(s) [Oxidation]

Reduction is the gain of electrons or a decrease in the oxidation state of an atom, an ion, or of certain atoms in a molecule.

Example: The reaction between magnesium oxide and carbon at 2000C to form magnesium metal and carbon monoxide is an example of the reduction of magnesium oxide to magnesium metal.

MgO(s) + C(s)  ------------    Mg(s) + CO(g) [Reduction]

An oxidation-reduction reaction is also known as a redox reaction.

The difference between Oxidation and Reduction is as follows:
