Multimedia is now-a-days used in every field like education, theatre, advertising, fashion, gaming to name a few.

Text is used to communicate information to the user.Text can be of any type, a word, a single line, or a paragraph.The textual data for multimedia can be developed using any text editor. The text can have different type, size, color and style to suit the professional requirement of the multimedia software. 

Audio 

Sound is the most important element of multimedia.The term sound is used in the analog form, and the digitized form of the sound is called audio. .wav is the most popular uncompressed sound format on the Internet, and it is supported by all popular browsers.

Image 

Images used in a multimedia application can be photographs converted into digital form with the help of scanners or generated on the computer.

A Pixel (short for picture element) is the small dot on the screen. A map is a two dimensional matrix of these dots. Thus, a bitmap is a simple matrix of tiny dots which forms an image on the computer screen. 

They store the images in the form of mathematical equations. On the screen both bitmap and vector graphics looks the same.

Video and Animation 

Animation can add great power to any multimedia application. Any static presentation becomes lively by adding a video or animation.The term video refers to the sequence of natural scenes captured using analog or digital video capturing device.

Animation is a visual change over time. The digital images are played one after the other to create a moving effect.
