One fundamental discrete structure on which all other discrete structures are built is SET. 
Sets have been used in mathematics since ancient times. It was the 19th century German mathematician Georg Cantor who was responsible for ensuring that sets had a home in mathematics. Cantor developed the concept of the set during his study of the trigonometric series, which is now known as the limit point or the derived set operator. 
Sets are considered as building blocks of discrete mathematics. Sets theory forms the base of several other fields of study like counting theory, relations, functions, graph theory etc. 
A set is simply a way to express a collection of objects like a set of students, a set of computers, a set of books, a set of courses or a set of numbers. 
You might have learnt some elementary facts about sets and set membership  along with Venn Diagram, in your early schooling. You may be well acquainted with the basic set operations such as set union and intersection. Let's revise those concepts and understand sets with whole new perspective - the perspective of discrete mathematics and computer sciences.
