Difference between CHAR & BYTE with respect to Storage

Question

Hi,
I HAVE CREATED THREE TABLES WITH DIFFERENT STORAGE FORMATS.
SQL> CREATE TABLE A
2 (ENAME CHAR);
Table created.
SQL> CREATE TABLE AA
2 (ENAME CHAR(1 CHAR));
Table created.
SQL> CREATE TABLE AAA
2 (ENAME CHAR(1 BYTE));
WHEN I AM TRYING TO INSERT THE VALUES
CASE1) INSERTING A SINGLE CHARACTER ONLY
SQL> INSERT INTO A
2 VALUES
3 ('A');
1 row created.
SQL> INSERT INTO AA
2 VALUES
3 ('A');
1 row created.
SQL> INSERT INTO AAA
2 VALUES
3 ('A');
1 row created.
INSERTING MORE THAN ONE CHARACTER IN AAA TABLE
SQL> INSERT INTO AA
2 VALUES
3 ('AA');
('AA')
ERROR at line 3:
ORA-12899: value too large for column "RAVI1"."AA"."ENAME" (actual: 2, maximum:
1)
SQL> INSERT INTO AAA
2 VALUES
3 ('AAA');
('AAA')
ERROR at line 3:
ORA-12899: value too large for column "RAVI1"."AAA"."ENAME" (actual: 3,
maximum: 1)
please can any one tell me the differences.
Thanks & Regards
