Components of multimedia
there are the following components of multimedia
1. Text: the text is the common way to communicate information to others. One of the basic multimedia components includes pictures, audio, and video, but text is the most common data type used in multimedia applications. Text used in multimedia can be categorized into two parts.
-static text: the static text is just plain or old text.
- hypertext: hypertext is a text which contains links to other texts.
2. Sound(audio): audio is an important component of multimedia. Multimedia is concerned with recording and playing sound. Sound is an important component of multimedia because this component increases the understandability and improves the clarity of the concept. Audio includes speech, music, etc. some audio formats are as blow.
1. MIDI: its full form is Musical Instrument Digital Identifier. It is a sound standard. It is a cheap source for musicians. These files are smaller than other music files. These files are mostly used for web pages.
2. Digital audio - Digital audio is mostly used in multimedia. These files are greater than MIDI files. Its sound quality is good. A special format is used for digital audio called WAV.
3. Images: Images are also an important component used in multimedia. Images are generated by the computer in two ways, such as bitmap or raster images and as vector images -
1. Raster or Bitmap images: the most common form for sorting images on a computer is a raster or a bitmap image. A bitmap is a simple matrix of the tiny dots called pixels that forms a raster or bitmap image. Each pixel consists of two or more colors. For example, MS Paint is a program that is used for creating Bitmap Images.
2. Vector Images: Vector Images are based on drawing elements or objects such as lines, rectangles, circles to create an image. We use programs to create images, which are called vector images programming. The advantage of the vector is the relatively small amount of data required to represent the images, and therefore, it does not require a lot of memory to store. We can't draw images directly with the help of Mouse.
4. Animation: In animation, still images are used for movement in a time. The animation consists of still images that are displayed so quickly so that they give an impression of continuous movement. for movement, a special number of effects are recorded. Animations may be two or three-dimensional. Specific software is used for animation like - Windows Movie Maker, Macromedia Director, and Flash.
animation is of two types -
1. path animation: A path animation is a type of animation timeline that uses Path Geometry as its input.
2. Frame animation: A simulation of movement created by displaying a Series of pictures or frames called free animation.
functions of animation :
* Draw attention
* to give presentation
* to practice
5. Video: Video is an important component of multimedia. In this, moving images are shown. Moreover, in the video, moving pictures are shown with sound. Video can be without sound. It is the best way to communicate with each other. in multimedia, it makes the information more presentable, and it saves a large amount of time. The video can be categorized into two types.
1. Analog video: the original video recording method stores continuous waves of red, green, and Blue intensives.
2. Digital Video: Digital video presents moving visual Images in the form of encoded digital data.
advantages of video:-
1. video information is effective because we can use audio images etc., to create animations.
2. Students can be taught easily with the help of videos.
