But it is deficient in systemic and comprehensive research of reliability theory. There is not adefinition of reliability which can be generally applied to present reliability research fields. So this paper will be based on introducing and analyzing the existing reliability definitions. And then educe amore exact definition of reliability. Finally, in order to prove the correctness of the new definition, we will analyze the new definition in depth from the angles of the relation between the software reliability and the hardware
