Answer / sreejith s t
Both Truncate and delete deletes the rows from a table .
But we cant use where clause in truncate statement . While
doing delete operation all the deleted rows are logged in
the transaction log . It reduces the perfomance . In
truncate operation no transaction logging is happening .
Delete is Autocommited but Truncate is Not .

Answer / ismail hasan
truncate deletes records from a table and while truncating a
table, the table will be dropped from the database and will
again be created automatically. No where clause is
acceptable in truncate statement and one can't restore the
previous data (i.e no rollback is possible) into the table.
It's an efficient process.
Delete statement will delete a particular row(s) on your
choice.
