1) Delete command maintained the log files in each deleted row but truncate command do not maintained the log files for each deleted row but maintain the record for DE-allocation
of data-pages in the log files

2)Delete is a DML command and truncate is a DDL command.
3)Trigger is fired in case of delete command only but they are not fired when truncate command is used.

4)you can used where clause in case of delete command use to delete a particular row,
but you can not use where clause in case of truncate command use to delete a data from rows.

5) Truncate command reset the identity property to its initial values whereas delete command can not reset its identity property of its column.
