It is important to understand that, like many other words in the language, the word “multimedia” also has several different meanings. Multimedia is: - a technology that describes the procedure for the development, operation and use of information processing tools different types; - an information resource created on the basis of technologies for processing and presenting information of various types; - computer software, the functioning of which is associated with the processing and presentation of information of various types; - computer Hardware, with the help of which it becomes possible to work with information of different types; - a special generalizing type of information that combines both traditional static visual (text, graphics) and dynamic information of various types (speech, music, video fragments, animation, etc.).

But even the most modern computer will not work without software. This: · operating system; · Applied multimedia applications. Applications include multimedia applications that the average user of a multimedia computer directly works with. First of all, these are computer games. This also includes multimedia encyclopedias, video and audio players, programs for creating and viewing presentations and many others.

Possibilities of multimedia technologies The undoubted advantage and feature of the technology are the following multimedia capabilities, which are actively used in the presentation of information: ─ the ability to enlarge (detail) the image or its most interesting fragments on the screen, sometimes by a twenty-fold increase (magnifying glass mode) while maintaining image quality. This is especially important for the presentation of works of art and unique historical documents; ─ the ability to compare images and process them with various software for research or educational purposes; ─ the ability to highlight “hot words” in the text or other visual material accompanying the image, which can be used to immediately obtain reference or any other explanatory (including visual) information (hypertext and hypermedia technologies);

─ the ability to provide continuous musical or any other audio accompaniment corresponding to a static or dynamic visual series; ─ the ability to use video fragments from films, video recordings, etc., the “freeze frame” function, frame-by-frame “scrolling” of video recordings; ─ ability to connect to global network Internet; ─ ability to work with various applications (text, graphic and sound editors, cartographic information); ─ the ability to create your own “galleries” (selections) from the information presented in the product; ─ opportunity automatic viewing the entire content of the product (“slide show”) or the creation of an animated and voice-over “guide” for the product (“talking and showing user instructions”); inclusion of game components with information components into the product; ─ the ability to “freely” navigate through information and exit to the main menu (enlarged content), to the full table of contents, or even from the program at any point in the product

A very fashionable direction in the development of multimedia technologies is virtual reality. Virtual reality is a way for a person to get almost real sensations from an unreal world. Modeling such an unreal world is done well using modern computer. Computer tools create such complete visual, sound and other sensations that the user forgets about the real world around him and is enthusiastically immersed in a fictional world. A special effect of presence is achieved by the possibilities of free movement in virtual reality, as well as the possibilities of influencing this reality. The simplest and least tedious entry into virtual reality carried out through a computer screen on which this reality can be observed. In this case, movement and influence on the virtual world is usually carried out using a mouse, joystick and keyboard.
