A Set which contains a Nonnegative integral number of elements is said to be finite. A Set which is not finite is said to be Infinite. A finite or Countably Infinite Set is said to be Countable. While the meaning of the term ``finite'' is fairly clear in common usage, precise definitions of Finite and Infinite are needed in technical mathematics and especially in Set Theory.
