Which one is faster DELETE/TRUNCATE?

Which one is faster DELETE/TRUNCATE?

Truncate is more faster than delete because when we delete the records from the database, database has to perform 2 actions.
> Delete from the database
> Write the deleted records into \"rollback\"  
segments. But incase of \"Truncate\" the second activity is not required.It is faster than becouse truncate is a ddl command so it does not produce any rollback information and the storage space is released while the delete command is a dml command and it produces rollback information too and space is not deallocated using delete command.
