Abstract
A computer system having a function of interrupting lewd/violent programs which includes a read-only-memory for storing an initialization program and a security grade setup program; a non-volatile memory device for storing a security grade which is a program classification code selected by a user for designating an unacceptable program content contained in an application program, and a password for identifying the user when changing the security grade; and a controller for controlling execution of an application program according to the security grade of the application program and the security grade stored in the non-volatile memory device during initialization, and for controlling the changing of the security grade stored in the non-volatile memory device during the security grade setup, when the user inputs a password that corresponds to the password stored in the non-volatile memory device. As a result, the computer system is able to limit access to application programs that contain unacceptable levels of graphic sex, violence, and strong language.
