The "text" multimedia type consists of digital files that use large amount of pre known symbols (such as numbers and letters) to store information. These alphabetic characters are arranged into words and sentences to be read and understood in a chosen language. Text files are capable of being viewed and stored on electronic devices, with examples of these files being .txt and .doc files.


Text files are some of the smallest out there, with files containing thousands of words and many different fonts often only being tens of kilobytes big. it is the most efficent way to store data.








Fonts are one of the core parts of the text media types. The font of a text affects its presentation either by changing the style of the text (font) or the size of the text (font size).



The difference

Fonts fall into two main groups, Serif and Sans Serif fonts. Serif fonts are text fonts that contain decorative flourishes on the end of strokes that contruct the letters and symbols used in the font. Sans Serif fonts are different because they do not have these decorative flourishes, sans literally meaning "without" (Sans Serif literally meaning "without Serif").


The "graphics" media type is one of the simplest forms of media, with graphics being used in many other media types (animation, video and [to a lesser extent] text). Graphic files are anything that produces a still image that you are able to view on an electronic screen as well as store onto an electronic device. Examples are .jpeg and .png files.


Depending on the quality of the picture a graphic file can range from hudnreds of kilobytes to tens of megabytes (on average).




"Morphing" is the process of combining two or more different graphic files to 

create a single image that combines aspects of all images used. A morphed picture is made in a way to make the end result seem natural and not obviously edited.


For examples see the images on the right.



The "audio" media type is one of the more basic forms of multimedia. Audio files are anything that consists solely of sound or audio (not counting cover images that music players sometimes display) that can be listened to on a digital device and stored on the same thing. Examples of audio files are .mp3 and .m4p.


Depending on the length and type of audio file an audio file can be of any size, though music mp3 files are on average a few megabytes.




To the right are two examples of audio files. Both have been shortened from their original length. The top file has not been edited further.


The other file has had it's pitch increased by 40% percent aswell as its tempo increased by 10%. All Edits were made in Audacity.



Animation and Video

"Animation" and "video" are two different forms of multimedia that serve the same purpose. Both forms of media are used to create the illusion of movement by showing similar still images at an extremly fast rate (known as frames per second). What makes these two different is that animation uses "artificial images" (man made drawings, paintings ect.) that are (usually) created using digital software, meanwhile videos use real life images that are (usually) captured by a digital camera. Both types of multimedia are usually packed together with audio that is played along with the animation/video. Examples of animation/video files are .mp4 and .gif files.


Depending on the length and quality of the animation/video files can range from anywhere from hundreds of kilobytes to tens of gigabytes.





This booklet alone is ripe with examples of interactivity. The hyperlinks attached to the contents page and the icons in the top right are just one example, with the interactive page flipping being another.


Besides this booklet are many more things in existance that are peices of interactive media. Simple things such as Microsoft Word, Adobe Photoshop and any videogame in existance are all examples of interactive media.

Interactivity is very different to the other aspects of multimedia in that it does not stand on its own, instead being combined with the other types of multimedia mentioned in the previous pages.


An interactive piece of multimedia is any electronic system that allows a person to interact with any of the other forms of media (text, graphics, audio, animation and video) in a way that combines, controls or manipulates them. Interactivity to the scale we see today has only been made possible by the advant of Web 2.0 and the advancement of multimedia as a whole.
