Null is not a datatype because we can't typecast null values. The memory occupied by null is 2 byte.

As per docs.oracle :
Oracle Database currently treats a character value with a length of zero as null. However, this may not continue to be true in future releases, and Oracle recommends that you do not treat empty strings the same as nulls.

NULL is not a data type. The key word NULL is used to mention the unknown or missing values of data.
For ex: while registering sign up form there are few fields which are not mandatory and if user didnt fill those non mandatory fields then those values we can save it as null in the data table.
