Modern types of interfaces are

1) Command Interface. The command interface is called so by the fact that in this kind of interface a person gives "commands" to the computer, and the computer executes them and outputs the result to the person. The command interface is implemented in the form of packet technology and command line technology.

2) WIMP - interface (Window - window, Image - image, Menu - menu, Pointer - pointer). A characteristic feature of this type of interface is that the dialogue with the user is not conducted with the help of commands, but with the help of graphic images - menus, windows, and other elements. Although in this interface, commands are issued to the machine, but this is done "indirectly" through graphic images. This kind of interface is implemented on two levels of technology: a simple graphical interface and a "clean" WIMP interface.

3) SILK - interface (Speech - speech, Image - image, Language - language, Knowlege - knowledge). This kind of interface is closest to the usual, human form of communication. As part of this interface is the usual "conversation" of the person and the computer. At the same time, the computer finds commands for itself, analyzing human speech and finding key phrases in it. The result of the execution of commands, he also converts to a human-readable form. This type of interface is the most demanding of computer hardware resources, and therefore it is used mainly for military purposes.
