Description

Computer body {COMPUTER}

TECHNICAL FIELD The present invention relates to computer manufacturing, and more particularly, to a manufacturing technology of a computer for client / server. With the recent improvement in computer performance, even personal computer systems can be used for client or server purposes depending on the type of operating system installed. Of course, a server computer can also act as a client when working in a network environment with other server computers, but a computer in which two functions of a client and a server operate simultaneously in one computer system has not yet been developed as a general personal computer. have. In general, one computer set includes a PC main body including a video card, a hard disk, a CPU, a RAM, a main board, an FD drive, a CD-ROM drive, a power supply, a main body case, and an external device such as a monitor, a keyboard, and a mouse. It consists of input and output devices. This is the most basic configuration in a modern Windows operating system environment. For this reason, if you need to build a client / server system environment for work, home, or study, you should have at least two sets of computers with the main body and peripherals as described above. This is not a problem for organizations, but it is burdensome for individuals, and it is not easy because individual users need to install two computers for client and server on the same desk for learning purposes, because they are expensive and take up a lot of space. In addition, most server computers do not operate devices other than the motherboard and hard drive, which is wasteful for individual users including home network administrators. Nevertheless, the recent computer work environment is increasingly based on the client / server system of the Internet environment. In particular, personal users, including students, are expected to expand their home networks, expand the use of P2P (PEER TO PEER) network technology, which has recently attracted a lot of attention, and learn programs that utilize programs in the client / server computer network (ie, the Internet) environment. The need to install a server is greatly increasing. In particular, since Linux is a good operating system that can secure the operating system and most applications for free or at a low cost, and has a powerful network function even on a low-performance computer, many users are installing it for learning. This also increases the need to install two computers on the same desk, but despite these advantages, Linux has been developed mainly for servers, which makes it inconvenient for individual users to use for clients and for client / server computer network environments. Even if the user tries to install and use it separately for the server, as mentioned above, it is not easy because of the cost burden. Of course, you can install the Linux operating system in the free space of a Windows computer's hard disk device for learning purposes, and select either Windows or Linux at boot time. However, because this method cannot be a client / server system based on a computer communication network, the program for the client / server system cannot operate properly. However, having a separate computer for the Linux operating system, which is rarely used, is not easy for individual users.

On the other hand, the above-mentioned problems when manufacturing a computer having two operating systems that can operate simultaneously while sharing a plurality of peripheral devices in one computer system, and thus easily have a client / server computer communication network environment. This solution could be the computer system many client / server system users wanted. Such computers will provide significant economic benefits and convenience to consumers, especially learners and home network owners who need client / server computer communication networks, thereby making a significant contribution to the development of industrial technologies in this field. . In addition, when the individual learner learns the client / server computer communication network-based technology, the user can conveniently practice without accessing the Internet environment as in the prior art.

According to the present invention, as a recent computer use environment is rapidly changed to an internet environment based on a client / server computer communication network, it is increasingly necessary for individual users to construct such a computer communication network environment for home use or learning purposes. In view of the fact that the situation is not being able to do so due to problems such as costs, the purpose is to provide a manufacturing technology of a computer body for a cheap and convenient client / server so that individual users can build such an environment inexpensively and easily.

The technical task for achieving the above object is to provide a technology that allows two computers mounted in one computer case to share the auxiliary storage device and the peripheral device set.

Another technical task for achieving the above object is to provide a technology for manufacturing a computer that functions as two computers for a client / server but occupies as little installation space as a conventional computer.

Another technical task for achieving the above object is to provide a technique for manufacturing a computer with two computer functions for a client / server at a low manufacturing cost.

Another technical task for achieving the above object is to provide a technology for manufacturing a computer that contributes to computer component saving and computer component recycling.

The summary (summary) of this invention is as follows.

The present invention installs two conventionally known mainboards equipped with a CPU and a main memory (RAM) in one computer main body to provide an auxiliary memory device, an input / output device and a peripheral device except a video card (video controller) and a hard disk. It is a technology that manufactures a computer body that allows two computers to share and operate at the same time. So, one of the two computers installs the operating system for the client and the other one installs the operating system for the server and connects two computers through a computer communication network device such as a LAN card to form a computer communication network. It will be possible. This makes the computer of the present invention seem to be a single computer, but is in fact a client / server computer different from the prior art computer in which two computers are operated. As used herein, the term "client / server computer" refers to the integration of two computer functions into one computer for convenience. A complete client / server computer must be installed with its operating system and a network card, such as a LAN card, to form a communications network. However, the computer of the present invention will be able to construct such an environment more easily than any computer of the prior art, and it will be easy to use such term because it is based on using it for such a purpose. In each of the embodiments of the present specification, it is assumed that Linux is used as an operating system for a server. This is because the client / server computer of the present invention is mostly used by individual users, and in the case of a Linux system, it can be obtained free or at low cost. In fact, other server operating systems, such as nt, can all be used if they are all working on a personal computer.

Hereinafter, a process of installing and operating a motherboard and an operating system program (hereinafter referred to as "operating system") in the computer of the present invention will be described with reference to FIG.

The installation process of the computer is as shown in FIG.

Preparing a main board and an operating system (M61);

First, the peripheral device connection device of the present invention, the power supply device and the auxiliary memory device of the present invention are mounted on the computer main body case of the present invention, and the two main boards each equipped with a CPU and RAM prepared in the motherboard mounting slot are mounted and hard. Installing a disc and a video card on each motherboard (M62);

Coupling a peripheral device connecting device second connector 12 and a main board power supply cable to each main board (M63);

At this time, the motherboard power supply cable of FIG. 4 and the second connector of the peripheral device connection device must be correctly coupled to the corresponding motherboard so that each motherboard changeover switch 6 and 7 and the power switches swA and swB are interlocked.

Connecting the peripheral device and the auxiliary memory device to the peripheral device connection part of the peripheral device connection device first connection part (M64); At this time, the auxiliary storage device and other devices (hub, etc.) are also connected to the power supply device.

Step M65 of booting the server computer by turning on the server-side mainboard switch 6 and 7 and the server-side main board power switch swA and turning on the power switch sw;

Installing a server operating system on the server computer (M66);

Booting the client computer by turning on the client-side motherboard switch 6 and 7 and the client-side motherboard power switch swB (M67);

By installing the client operating system on the client computer (M68) it is possible to install the motherboard and each operating system.

After the above steps, the computer of the present invention may be operated while switching the switch according to the needs of the user. According to the selection result of the mainboard switch (6, 7), the client environment, the server environment, and the client / server environment based on the computer communication network, etc. The user can simply switch to the desired working environment. Of course, if you only want to boot each motherboard, the other computer can work with it turned off.

Therefore, the system environment can be freely changed as desired by the user, so it can be used for various purposes according to the needs of the user.

The present invention seems complicated due to the need to operate the mainboard switch (6,7) and each mainboard power supply switch (swA, swB), but in practice the mainboard switch when the server computer is operated for 24 hours Usually needs to be switched to the client side, so in most cases only the client power switch needs to be turned on and off.

As described above, the present invention is to allow two mainboards to be installed in one PC main body so that it looks like one computer, but in reality it is a computer that can operate two computers at the same time. As a result, it is possible to selectively operate three operating systems: client, server, and client / server, so that the user can pay extra cost as much as the peripheral device price compared to the conventional computer (additional motherboard is used in possession) (Assuming you install Linux as your server operating system). In this regard, the economics and efficiency of this product can be said to be difficult to obtain by any high technology of the prior art or expensive computer.

While the preferred embodiments of the present invention have been described above, it will be apparent to those skilled in the art that various modifications and changes can be made without departing from the spirit of the present invention.

Basically, the present invention allows individual users to have a client / server computer system at a low cost. The effects of the present invention are described in terms of contributing to industrial development in this field.

In the prior art, when an individual user wants to produce and practice a client / server program such as CGI, it is difficult to practice without a practice room equipped with such an environment, unlike a client-only program. However, as described above, an individual user can not only construct a client / server system through the present invention but also by using a client / server computer communication network formed in one computer case without accessing the Internet. As practice can be done, consequently, client / server computer network users and learners will be able to contribute to the improvement of this field.

3. Expansion of home network

In the prior art, it is not easy to construct a home network due to cost problems, but the present invention solves the server construction problem more easily, and the server according to the present invention can be used for a router or the like. This allows multiple computers on a home network to access the external Internet at the same time, and can be used as a home web server.

In addition, the server of the present invention can also be used as a server system for controlling various home appliances of the Internet by accessing the web server of the home network from the outside.

4. Expanding Linux Distribution

The field which is greatly helped by the practice of the present invention is regarded as the Linux technology field. Until now, it was not easy for an individual to have a server, but due to the implementation of the present invention, an individual can also have a server computer without any cost, and in the case of Linux, there are many limitations for using a client, but since it is a free supply system, The combination will greatly expand the user base and make a significant contribution to technological advances in this field.

5. Expanding P2P (PEER TO PEER) Network Technology

P2P communication network technology is used to perform network operation such as direct data transfer between personal computer and personal computer through IP address without going through various servers provided by ISP, etc. In this case, considering that it only works when necessary, there may be a limitation in the development of the technology in this field, but if a user uses the present invention as a server, data can be transmitted / received for 24 hours from a P2P-related internet business.

6. Recycling Used Computers

In the present invention, a set of computer input / output devices and the like are shared by two computers provided in one computer case, and in the case of individual users, when installing Linux for a server, a 486 or a low speed Pentium CPU equipped with a motherboard can be utilized. This makes it possible to install server computers without any cost or expense. In particular, due to the development of computer manufacturing technology, the number of mainboards that are discarded due to the rapidization of the existing computers is increasing. As such, the mainboards can be recycled into servers or client computers using the present invention. In terms of protection and resource recycling, it will be able to achieve two sets of effects.
