The cardinality of a set is the number of elements in the set.
Cardinality of a set refers to the measure of the "number of elements" in that set. It can be finite, such as the set of integers from 1 to 10, or infinite, like the set of all natural numbers. Cardinality is often used to compare the sizes of different sets, and sets can be categorized as countably infinite or uncountably infinite based on their cardinality. For example, the set of real numbers has a higher cardinality than the set of natural numbers.
