Second, the noun explanation

1. The so-called media refers to the media that spreads information, which is a publicity platform in layman's terms. Anything that can provide a platform for information dissemination can be called media. As for the content of the media, it should be constantly updated according to the current relevant national policies and the actual needs of the advertising market to ensure its feasibility, applicability and effectiveness. Previously, the four traditional media were:

1, newspaper;

2. TV;

3. broadcasting;

4. magazines;

In addition, there should be outdoor media, online media and new media, such as short messages.

With the development of science and technology, new media, such as IPTV and electronic magazines, are gradually derived. They are developed on the basis of traditional media, but they are qualitatively different from traditional media.

In order of appearance:

1, newspapers and periodicals should be the first media;

2. Broadcasting should be the second media;

3. Television should be the third media;

4. Internet should be called the fourth media;

5. The mobile network should be the fifth media.

2. The English word for Multimedia is multimedia, which consists of two parts: media and multi. Generally understood as the synthesis of various media.

Multimedia technology is not a simple combination of various information media. It is an information technology that combines information in the form of words, graphics, images, animations and sounds, and is comprehensively processed and controlled by a computer, which can support a series of interactive operations. The development of multimedia technology has changed the application field of computers, which has changed computers from special products in offices and laboratories to ordinary tools in the information society, and has been widely used in industrial production management, school education, public information consultation, commercial advertisements, military command and training, and even family life and entertainment.
