difference between TRUNCATE and DELETE

TRUNCATE :
ddl command.
truncate being a ddl is auto commit.
we can only truncate the whole table(cant use where clause)
once table is truncated we cant rollback the changes.
when a table is truncated the memory occupied is released.

DELETE :
delete is a dml command and can be rolled back.
is slower than truncate as it is dml has to go through rollback segments etc.
we can use where clause with delete.
when a table is deleted memory occupied is not released
