Computer system and control method thereof

摘要

A computer system which has a connection port to transmit data is provided with a user input unit through which a user inputs a password; a switch which is turned ON/OFF to transmit data through the connection port; and a processor subsystem which outputs a control signal to control operation of the switch to transmit data through the connection port, when the input password matches a preset password. As a result, the computer system is able to efficiently control data transmission between a processor subsystem and an external storage device.
