1. Elements of Multimedia
1.1. TEXT
1.1.1. A broad term for something that contains words to express something.
1.1.2. - Text is the most basic element of multimedia.

1.2.1.1. where each pixel is separately defined (as in a digital photograph). GRAPHICS
1.2.2. vector graphics,
1.2.2.1. where mathematical formulas are used to draw lines and shapes, which are then interpreted at the viewer's end to produce the graphic

1.3.1. WAV -
1.3.1.1. Audio files can be created in many formats. One of the oldest and most common formats is WAV - a file extension which stands for Waveform Audio Format.
1.3.2. MP3
1.3.2.1. audio file format is perhaps the most recognized of all due to the popularity of MP3 players in today’s society.(the Moving Picture Experts Group (MPEG))
1.3.3. MP4
1.3.3.1. audio file format is becoming increasingly recognized by users of the video iPod since MP4 file formats can not only hold audio data but they can also hold video data as well

1.4. ANIMATION
1.4.1. Animation is the rapid display of a sequence of images to create an illusion of movement. The most common method of presenting animation is as a motion picture or video program, although there are other methods.
1.5. VIDEO
1.5.1. Is the technology of capturing, recording, processing, transmitting, and reconstructing moving pictures.
1.5.2. Video is more towards photo realistic image sequence / live recording as in comparison to animation.
1.5.3. Video also takes a lot of storage space. So plan carefully before you are going to use it.
2. Authoring Tools
2.1. Use to merge multimedia elements (text, audio, graphic, animation, video) into a project.

6.1. that computer information can be represented through audio, video, and animation in addition to traditional media (i.e., text, graphics/drawings, images).
6.2. a combination of text, graphic, sound, animation, and video that is delivered interactively to the user by electronic or digitally manipulated means
6.3. a is the field concerned with the computer controlled integration of text, graphics, drawings, still and moving images (Video), animation, audio, and any other media where every type of information can be represented, stored, transmitted and processed digitally
