A computerized system for simultaneous operation of multiple environments and method for storing distinct data types separately is disclosed. The computerized system includes a plurality of main host, sub-host, data storage and network devices wherein data of a first type is stored on main host, data storage and network devices and data of a second type is stored on one of the sub-host, data storage and network devices, wherein data of a third type is stored on at least another one of the sub-host, data storage and network devices, and data of a forth type is stored on at least another one of the sub-host, data storage and network devices, wherein all of the data types requires controlling access thereto. The invention provides for ensuring the integrity and separation of the data stored on the sub-host, data storage and network devices. It also prevents misappropriation of data stored on the devices. The invention includes a control device which selects between the main host and anyone of the sub-host, data storage and network devices for use with a computerized system. Selecting a sub-host, data storage and network device activates and places it in an operational mode. The remaining main host system and sub-host, data storage and network devices and peripherals are placed into a standby operational mode.
