Description

Network computer terminal for general use of SKT.

This device relates to the use of computer networks of local type of various topologies and can mainly be used in the following areas:

on railway transport (at railway stations and stations);

on motor vehicles (at bus stations and bus stations);

in the subway (at stations and subway crossings);

on air transport (at airports and airports);

at the enterprises of postal, telegraph and telephone communications; 4 in branches and branches of Sberbank and other banks;

4 in other public places (in the presence of covered premises and a general telephone network of the GTS, as well as with high attendance by people).

In addition, this device can be used as a subscriber station (workstation) and in small in size and number of users of computer networks in offices and production facilities of enterprises (organizations and institutions) of various industries.

There are various GOM-compatible personal computers (PCs) that are used as workstations (subscriber stations) in computer networks for various purposes and which differ in the clock frequency of their microprocessors, the memory size of their read-only memory devices (ROM) and random access memory (RAM) ), its configuration, hardware device, etc. (1., p. 22-23, 31-40).

Disadvantages are the presence in the system units of PCs, drives for 3.5 and 5.25, for CDs and their controllers, which complicates and increases the cost of PCs and which may not be used when working with PCs on a network.

Various monitors (displays) are known, monochrome and color, of different diagonal screen sizes, with a cathode ray tube and liquid crystal, of various resolutions, which, together with a PC, are part of the workplace (1., p. 44-45).

The disadvantage is the display of a complex and incomprehensible for an ordinary unskilled user graphical interface (when working in the environment

yOi6iS

MKI: G11C19 / 30

Windows), as well as the MS DOS interface, which does not provide the necessary level of capabilities when working with modern application programs.

For all types of PCs, various types of keyboards are used to enter characters into a computer (1., p. 77-83).

Disadvantages are the presence of a large number of keys, the purpose of which is incomprehensible to unprepared users and which are used to perform specific commands that are not required to perform many specific application tasks, possible dropping of buttons, possible involuntary execution of an unnecessary command at the moment, or failure to complete the desired one.

There are various devices for printing text and graphic information - printers, divided into matrix, inkjet and laser (1., p. 49-50).

The disadvantages of dot-matrix printers are relatively high noise during operation, low printing speed, low print quality, and unsuitability for color printing. The disadvantages of inkjet printers are the risk of ink drying inside the nozzle, insufficient moisture and heat resistance of the printed image on paper, the high cost of a printed sheet compared to dot matrix printers. The disadvantages of laser printers are the even higher cost of printing compared to previous types of printers, the high cost, especially color printers.

Known devices for entering into the computer a variety of text (including handwritten) and graphic images, scanners, which are divided into hand, drum and tablet (2.).

The disadvantages of hand-held scanners are the limited display area and bit depth, low density range. The disadvantage of drum scanners is their very high cost and inaccessibility to a wide range of users. The disadvantages of flatbed scanners are the smaller, in comparison with drum scanners, range of color reproduction, worse quality of reproduction at multiple magnification.

Known devices for connecting PCs to computer telecommunication systems that work through the general telephone networks of the GTS - modems (fax modems) and are classified according to various criteria: by speed and mode of data transfer, by the type of channels used (dial-up and

non-commutable), on the use of various protocols, on the design (external and built-in), the presence of additional functions (1, p. 50).

The disadvantage of external modems is the need for an autonomous power supply from the Central Committee and the manufacture of its own housing. General disadvantages: the need to adapt imported modems to domestic telephone networks.

Other external (peripheral) devices for working with a PC are known (pointing devices such as a mouse, joystick, trackball or touchpad, devices for storing large amounts of information - streamers and magneto-optical disks, multimedia and much more) (1., pg. 41-42, 4749).

Disadvantages - the ability to use them only for existing types of PCs of serial production and the impossibility or unnecessary use of them in a yukagny computer network of a tree topology of public use, indicated in the application for the invention of entry. No. 5 May 1998

A PRINTiva 1700 device is known that combines a full-color inkjet printer and an integrated scanner with a resolution of 600x600 dpi manufactured by Sitizen (3.).

The disadvantage is common to all scanners and printers, in addition, the impossibility of autonomous operation in computer networks.

A common drawback of all these types of devices is that each device cannot perform a full range of work when working on a computer network: input / output of information at a subscriber station from / to various media and its transmission / reception from / to the server managing computer network.

The closest known analogue (prototype) is the Panasonic UF-342 multifunctional combined device, which includes a fax on a regular paper, an inkjet printer, an A4 copier, a fax modem, a TWAIN-compatible scanner, and a power supply (4.).

Disadvantages - the absence in this unit of a motherboard with a central processor, keyboards with alphabetic and control buttons for processing

outgoing and incoming information, a monitor for visual control of the information processing process, as a result of which this device is designed to perform a strictly defined set of functions. In this constructive
