The 'text' data type is a string of characters such as letters, numbers, symbols or punctuation. Text should emphasise the main message as well as provides information.

 Serif vs Sans-Serif Fonts

The difference between these two fonts is that serif fonts have small decorative flourishes on the ends of some of the strokes that make up letters and symbols, whereas sans-serif fonts do not.


Serif - Baskerville, Times New Roman, Elephant, American Typewriter

Sans-serif - Arial, Calibri, Century Gothic, Tahoma, Verdana


The 'audio' data type in multimedia is digitised sound that consists of waves that represent change in air pressure. Audio is important in multimedia as it enhances the presentation by giving it greater reality. It is used for the illustration and demonstration of concepts.


The changes I have made to the original music file were changing the pitch and frequency. The original pitch was 'A', and I changed this to 'E'. The frequency originally was 14080.000Hz and I changed it to 10548.082Hz. These changes made the voices in the new audio become muffled and lower pitched, however it made the background music higher pitched.

The 'graphics' (or image) data type in multimedia are digitised pictures that communicate ideas wider than text, add interest, are used for analysis and aids in visualisation and communicating information.


Morphing is the smooth transformation of one image into another by computer, as in a motion picture.

The 'video' data type in multimedia is the continuous stream of data (graphics and sound) first created and then broken down into separate frames. Video in a presentation provides reality.


The 'animation' data type in multimedia is the illusion of movement achieved by displaying a series of static images in a rapid sequence. Animation allows movement to be demonstrated and adds interest.


Interactivity is the communication between humans and computer software. Examples of interactive applications include training programs, video games, electronic encyclopedias and travel guides.

Interactivity is also demonstrated in this book, through the use of hyperlinks and the 'page flip' function.

It is essential in multimedia as it increases learning, is practical and engaging.


  • Numerous studies over the years have shown that interactive multimedia learning takes less time, is enjoyed more and increases learning.
  • Interactivity is practical. It is capable of presenting real life situations that learners face every day. Adults are very practical learners as they learn best when faced with real problems that have real consequences. 
  • Multimedia with interactive functions such as video, audio and graphics keep learners interested and reinforces skills. Because it is exciting, challenging, and fun to use, it encourages learners to return to the program continually.
