The aleph numbers are a sequence of numbers used to represent the cardinality (or size) of infinite sets that can be well-ordered.
The cardinality of the natural numbers is $\aleph_0$.
The next larger cardinality is $\aleph_1$.
Then $\aleph_2$ and so on.
Aleph-Null: $\aleph_0$
Aleph-null is the cardinal number of a set which is in one-to-one correspondence with the natural numbers $\N$.
