The difference between revocation, revocation and cancellation: 1, different in nature (1) revocation is an act of exercising legal punishment, which is mandatory and punitive; (2) Revocation is a kind of legal withdrawal of administrative license, which has the characteristics of deprivation, irreversibility and remedy; (3) Cancellation is also a legal act to a certain extent, which is punitive and procedural in nature. 2. Different concepts (1) Logout means sending a request to the system to clear the currently logged-in user, and then you can use other users to log in to your system. Logout is not a substitute for restarting, but can only clear the cache space and registry information of the current user. (2) Revocation refers to the organization's cancellation of qualifications, that is, the qualifications held by a natural person or legal person are expired or no longer meet the requirements of qualifications and qualifications, which is a kind of cancellation behavior taken by the qualification issuing management. (3) Revocation refers to the withdrawal and cancellation, that is, revocation refers to the execution process in which the department with jurisdiction stops the object that originally permitted an activity and withdraws the permitted text, which is generally mandatory. The cause is basically because the object violates or violates the agreement when issuing the text. 3. Different objects: (1) Logout means sending a request to the system to clear the currently logged-in user. (2) Revocation refers to the organization's cancellation of qualifications. Revocation is a direct withdrawal and cancellation, which is generally made by a powerful department, and its consequences are generally guaranteed to be implemented. (3) Revocation: it should be mainly compared with revocation, because it is also aimed at units. Generally speaking, as long as the revoked person does not take the initiative to find the unit that decided to revoke, then the unit that made the revocation decision cannot directly force the revoked person to return his license or official seal. In general, some of the original licensing procedures have not been recovered, but only announced in the form of newspapers or advertisements, declaring some of its functions invalid.
