Finite set is a set that has a finitenumber of elements. For example,
in alphabets we have only 26 letters.
{a,b,c,d,...................z}
Infinite sets may be countable or uncountable.
Some examples are:
the set of all integers, {..., -1, 0, 1, 2, ...}, is a countably infinite set;
the set of all real numbers is an uncountably infinite set.
