Theoretical Computer Science

Usually, computer science seems like a practical field that involves studying, building, and working closely with computers. However, a subclass of this discipline also centers on the mathematical factors of the same.

This discipline falls under the umbrella of discrete mathematics, which is the study of countable or discontinuous mathematical structures.
