Description

Thin client with functional expandability

The present invention relates to a new client computer, and more particularly, a new concept having a main unit provided with components to enable basic computing of the new client, and having a separate extension unit to expand functions according to a user's needs. Relates to a new client computer.

In modern times, computers are used in various fields such as learning, business, and industrial so that they are called "mechas" of high-tech industries.

The first computer eniac was the first computer, and general PCs such as desktops, laptops, notebooks, etc. appeared. Recently, the network concept of client / server model was introduced with the introduction of the network concept. The system is being built.

However, as the hardware specification of the PC is improved due to the development of the existing client / server environment, the burden of software has been increased on the client, and the burden of installation and maintenance of the client is increased.

In order to solve the above problem, recently, a next generation computer called a server-based computer, that is, a thin client or a web terminal, has appeared.

The new client runs 100% of all applications on the server, and the client acts as a simple terminal that shows only the server's execution results. All associated clients can use the application, so there is no need to install it separately on the client's hardware.Therefore, by introducing a new application, there is no need to upgrade the client's hardware specifications, and care for software distribution or installation. no need.

In addition, server-based computing products have the ability to seamlessly transfer applications developed for the existing client / server environment to the web-based system without any programming, thereby reducing development costs. As this greatly reduced, there is an advantage to reduce the work load.

However, the computer has a problem in that the installation space is saved due to miniaturization as all the concentrated parts are integrally installed on the mainboard, while the price of the new client computer itself is increased due to the production of small parts.

Due to the above problems, although users prefer new clients, they have a problem that they are not popularized to this day because they are reluctant to use a small computer because they are expensive.

In addition, every time a new computer is released, it aims only for the latest new technology and does not support LPT, parallel port, serial port, and ISA method, which are the interface means of peripheral devices (print, mouse, keyboard), and the latest interface means. As only PCI, USB, IEEE 1394, and infrared ports are provided, peripheral devices that do not support the latest interface means have a fatal problem.

In order to solve the above problems, the new client computer according to the present invention is composed of a main unit provided with basic components for performing basic computing, and an extension unit providing function expansion in connection with the main board.

An object of the present invention is provided with a main unit having a minimum function so that the user can selectively use only the functions of the computer that are necessary, but the expansion of the auxiliary storage device to be used in various ways depending on the user's needs, applications and It is to provide extension of scene client through extension.
