Definitions
Multimedia is a combination of text, art, sound, animation,
and video.
It is delivered to the user by electronic or digitally manipulated
means.
A multimedia project development requires creative, technical,
organizational, and business skills.
Multimedia becomes interactive multimedia when a user is given
the option of controlling the elements. Interactive multimedia is called hypermedia when a user is provided
a structure of linked elements for navigation.
Multimedia developers develop multimedia projects.
The software vehicle, the messages, and the content together

A multimedia project shipped to end-users with or without
instructions is called a multimedia title.
A project can also be launched on the Web. Multimedia projects can be linear ornonlinear.
Projects that are not interactive are called linear.
Projects where users are given navigational control are called non-
linear and user-interactive.
Authoring tools are used to merge multimedia elements into a
project.
These software tools are designed to manage individual
multimedia elements and provide user interaction.

Hardware
A Multimedia computer is an ordinary computer with some built-in
features that can read and manage sound and image data. To develop Multimedia content and applications, you will need a
fast, multimedia capable computer system incorporating some of
the following:
High-resolution graphics and a large monitors
A Video display card
Sound cards
A CD-ROM or DVD Drive
Stereo 16-bit sound capabilities with amplified speakers
A high-speed modem

RAM (Random Access memory)
A removable large-capacity storage device, such as a CD-ROM(CD-RW),
Zip drive
A CD-ROM or DVD-ROM burner for creating your own master CD-ROM or
DVD-ROM
A flatbed scanner
A good-quality digital camera
A video capture/video printing card
A good-quality computer microphone

Software Multimedia software provides specific instructions to the
hardware for performing tasks.
Software tools are divided into production tools and authoring
tools.
Examples
A Graphic design photo-editing application
A 3D modeling and animation application A digital sound editing application
A nonlinear digital video editing application
Multimedia authoring application
Web-page authoring/design tool

Creativity
It is difficult to learn creativity, but the better you know
your medium, the better you are to express your
creativity.
In a multimedia project, being creative implies
knowledge of hardware and software.

Organization Skills
It is essential to develop an organized outline detailing the skills, time,
budget, tools and resources needed for the project.
Assets such as graphics, sound and the like should be continuously
monitored throughout the projects execution.
A standardized file-naming procedure should be followed for precise
organization and swift retrieval.

The most significant platforms for producing and delivering multimediaprojects are :
Apple Macintosh OS Mac OS X, Tiger, Leopard
Microsoft Windows OS Windows XP, Vista
These systems provide an easy-to-use graphical user interface (GUI).
The Macintosh as well as Windows PC offers a combination of
affordability, and software and hardware availability.
The Macintosh platform is better suited for multimedia production than the
Windows platform. The hardware platforms provided by Apple are better
equipped to manage both, sound and video editing.

A computer-assisted presentation are divided into four differentlevels :
Slide Presentations
Linear presentation (one slide after another) developed using
primarily text, graphics, and pictures. No interaction or
branching
Multimedia Presentations
Developed using text, graphics,, charts, sounds, digitised
video, computer animations and/or pictures in which no
interaction between user and computer has been incorporated

Interactive Multimedia Presentations
Developed with the same elements as previous category but
incorporate built-in interaction between user and computer. This
interaction can be in the form of data-entry, multiple-choice or true
false, interaction with screen objects and other possibilities. This type
of format is appropriate for information kiosks and computer-assisted
education program
Multimedia Web Pages
It is initially developed using the above mentioned tools but it needs to
be compressed using specialized tools. These tools allow the
application to be playback through Web Browser.
