<p>The present invention is directed to a computer system that has 2 computer main frames accessing independent networks in the same space, and can operate the 2 computer main frames through only one external input/output (I/O) device, e.g., a mouse, a keyboard, a monitor, and a sound output device (speaker) using a switching device. Accordingly, it is possible to selectively access at least 2 networks using only one computer system and separate the networks from each other, thereby improving user convenience and protecting a major network requiring security.</p> |
