character can allocates static memory and range is 1-2000 characters datatype is char (size). varchar can allocates dynamic memory and range is 1-4000 characters datatype is varchar2(size).

In char, we will give particular no of characters correctly but, in varchar, we will variable no of characters into it for example, if u Give the attribute type as char(20),you will Give 20 characters fully but if you give varchar(20), you give maximum 20 characters into the attribute
