Embodiment Construction

[0017] Such as figure 1 It is a structural diagram of a dual-purpose computer in the present invention. Among the figure, 1 is the actual display, 2 is the chassis, 3 is the operating system memory, 4 is the main board of the computer, and 5 is the switch. The user operates the switch 5 to select one of the storages with the operating system to work, and closes the other storages with the operating system at the same time, so as to achieve the purpose of selecting as public or self-use.

[0018] Beneficial effect

[0019] The invention makes the computer dual-purpose, which can be used as a safe and stable computer completely isolated from the outside world, and can also be used as a computer for Unicom.

Abstract

The invention is a dual-purpose computer. When safe and stable self used preparation documents, control appliance, detecting, analyzing calculation, entertainment, etc. are required, an operating system memory without connecting to other outside computers is selected, and memories of other operating system are closed, thereby a computer environment completely isolated to the outside world is obtained, any virus or attack can not come in. When it is needed to connect to outside computers, an operating system memory with the connection function is selected, and the self used operating system memory is closed, thereby the outside world computer is incapable to enter to destroy or steal data. As a dual-purpose computer, the invention can not only as a computer completely isolated to outside world which can secure safe, steady, no stealing and no interference, but also can be as a connection used computer.

Description

technical field [0001] The invention relates to a dual-purpose computer. Background technique [0002] Computers are divided into public use and personal use according to their purposes. Public use uses the network or other means to communicate with other computers, and personal use is used for document preparation, control equipment, detection, analysis and calculation, entertainment, etc. The workload of the two is almost the same size. However, today when computers enter the Internet era, since computers are usually connected to the Internet, it is inevitable to encounter security problems, data theft and computer virus infringement problems, which cause great troubles and even great property losses to users. In order to consider the safety and stability of the most important part of daily use, it is generally used to purchase a dedicated computer that is not connected to the Internet for the latter purpose. This way causes waste of resources, increased space occupation...
