Multimedia products can be divided into several categories depending on which consumer groups they are aimed at. Multimedia products can be divided into several categories depending on which consumer groups they are aimed at. 1. The first category for those who have a computer at home is educational, developmental programs, all kinds of encyclopedias and reference books, graphics programs, simple music editors, etc. Program CDs are so popular among home multimedia users that the number of CD titles on the market doubles every year.
2. The second category is business applications. Here multimedia serves other purposes. With its help, presentations come to life, it becomes possible to organize live video conferences, and voice mail replaces an office PBX so well that regular phone begins to be perceived as archaic. And, of course, nowadays the computer is becoming indispensable for accountants, economists, managers and many other specialists who use it for complex accounting and statistical calculations. Nowadays, personal computers are becoming indispensable assistants, without which no small enterprise or large corporation can do.
The use of multimedia in education and training (Computer Based Training - CBT) is intended for both personal use and business. This area of multimedia application will become increasingly important in the future as the knowledge that provides high level professional qualifications are always subject to rapid changes. Today's level of development, especially in technical fields, requires constant updating, and enterprises whose development is based on competition must be very flexible in their activities.

Significant positive factors that speak in favor of this method of acquiring knowledge are the following: Significant positive factors that speak in favor of this method of acquiring knowledge are the following: 1. better and deeper understanding of the material being studied, 2. motivation of the student to contact a new area of knowledge , 3. time savings due to a significant reduction in training time, 4. acquired knowledge remains in memory for a longer period and is later more easily restored for use in practice after a short repetition, 5. reduction in costs for industrial training and advanced training. training and professional development.
One of the most important areas of application of multimedia is the management of documents, contracts, invoices, official correspondence, etc. This information is almost without exception recorded on a write-once medium, and this information is not used very often in the future. By using special programs this documentation can be read and viewed at any time.

Multimedia breaks stereotypes and revolutionizes the idea of what a program user interface is and how information can be conveyed. With coming operating systems having GUI, program developers have no limits on their imagination. The most famous operating systems with such an interface today are System 7.5 for Macintosh computers, Windows 95/98/2000/ME/XP, OS/2, MagicCap, X-Windows (for Unix).

From the text interface there was a transition, first to a graphic one, which simply presented information more clearly, and then to third-generation Internet technologies, where the graphic interface is used to generate requests to the intelligent communication environment.
Multimedia is directly related to the development of Internet technologies. It has become possible to send audio and video messages via e-mail, as well as communicate via the Internet in real time, while seeing the interlocutor on the computer screen, which until recently was just a dream. Technical solutions have existed for several years now. Even the most inexperienced user can now easily connect to the Internet, find, view or even listen to any information he is interested in from anywhere in the world, and all this has become possible with the development of multimedia technologies.

Multimedia technologies in education
Currently, teachers are faced with the problem of a decrease in the level of cognitive activity of students in the classroom, a reluctance to work independently, and simply to study. Among the reasons why children lose interest in classes, one must certainly mention the monotony of lessons. Only a creative approach to the construction of a lesson, its uniqueness, richness in a variety of techniques, methods and forms can ensure effectiveness. There are many ways to develop students' cognitive activity. One of the ways is the use of multimedia technologies, which make it possible to increase the level of activity of schoolchildren and attract the attention of students.
Multimedia technologies are technologies that make learning more effective by involving people in the process of perception. educational information most of the sensory components of the learner.
Multimedia and hypermedia technologies integrate powerful distributed educational resources; they can provide an environment for the formation and manifestation of key competencies, which primarily include information and communication. Multimedia technologies open up fundamentally new methodological approaches in the general education system.
Multimedia is the interaction of visual and audio effects under the control of an interactive software Using modern hardware and software, they combine text, sound, graphics, photos, video in one digital representation.
Hypermedia are computer files linked through hypertext links to move between multimedia objects.
The use of the video method in the educational process provides the opportunity to: provide students with more complete, reliable information about the phenomena and processes being studied; increase the role of visibility in the educational process; satisfy the needs, desires and interests of students; release the teacher from part technical work related to control and correction of knowledge; establish an effective feedback; organize complete and systematic control, objective accounting of progress.
Educational multimedia presentations
The forms and place of use of a multimedia presentation (or even a separate slide) in a lesson depend on the content of this lesson and the goal set by the teacher. However, there are some general, most effective methods for using such benefits:
When learning new material. Allows you to illustrate with a variety of visual aids. The application is especially beneficial in cases where it is necessary to show the dynamics of the development of a process. When fastening new topic To test knowledge Computer testing is self-testing and self-realization, it is a good incentive for learning, it is a way of activity and self-expression. To deepen knowledge, as additional material for lessons.
When checking frontal independent work. Provides, along with oral, visual control of results. When solving educational problems. Helps to complete a drawing, draw up a solution plan and control the intermediate and final results of independent work. A means of emotional relief. Multimedia programs look like a video film, but with the ability to intervene in the course of action and conduct a dialogue. As a means for producing didactic handouts. Personal Computer in the hands of a teacher, in addition to a scanner and printer, this is a teacher’s mini-printing house.
