Animation       A multimedia application can require speech, music, and sound effects. The term “audio”
                                     An animated image can make a still image appear to be in motion. An animation
                                     or “sound” is used to describe them in relation to multimedia. Speaking is a wonderful

                                     used to describe the original sound signal. On a computer, digital sound is preserved.

                                     Therefore, digital audio is used for sound in multimedia applications.

                        Video         A moving image that is accompanied by sound, such as a television image, is referred
                                      to as “video.” The video portion of a multimedia application efficiently transmits a lot
                                      of information. Digital video is useful for presenting real-world objects in multimedia
                                      applications.  The  video actually  has the  biggest demands for  computer  memory  and
                                      bandwidth when it is uploaded to the internet. Similar to other data, the quality of digital
                                      video files can still be maintained while being saved on a computer. Digital video files can
                 be transported through a computer network. The digital video clips are easy to change.


              Modern  browsers  can  accept  a  variety  of  multimedia  formats,  and  multimedia  elements  are  frequently
              included in modern web pages. Media files are used to store multimedia components (such as audio or films).
              Examining the file extension is the most popular method for determining the kind of a file. A browser will
              treat a file as an HTML file if it has the .htm or .html extension. An XML file has the .xml extension, whereas
              a style sheet file has the .css extension. Image files have extensions like .gif, .png, and .jpg, which are used to
              identify them. Additionally, multimedia files have their own formats with various extensions, including .swf,
              .wav, .mp3, and .mp4 respectively.

              Advantages of Multimedia

              Multimedia components have been incorporated into Websites
              since the 1993 release of the Mosaic Web browser. The simple
              addition of a few photographs quickly evolved into the inclusion
              of many forms  of multimedia  and immersive settings. Let us
              study the advantages of Multimedia.
                It’s  integrated  and  interactive: All of the various media are
                 integrated during the digitalisation process. Interactivity is
                 improved by having access to fast feedback.

                It is incredibly user-friendly: As they can sit and watch the
                 presentation, read the text, and listen to the audio, the users do not need to expend much energy. Data in
                 text, image, and audio form can possibly promote information.
