What is Digital Media?

Digital Media is the form and technology used to communicate information. Multimedia presentations, for example, combine sound, pictures, and videos, all of which are different types of media.

Although digital representations are approximations of analog events, they are useful because they are relatively easy to store and manipulate electronically. The trick is in converting from analog to digital, and back again.

Sound becomes represented by numbers; pictures become dots of color, painted by logarithms. We think, see, and hear almost at the speed of light. These pages will be useful to those of us who use new technologies to aid us in transforming our work and our students' futures.

Digital vs. Analog

Digital describes any system based on discontinuous data or events. Computers are digital machines because at their most basic level they can distinguish between just two values, 0 and 1, or off and on.

The opposite of digital is Analog The analog format is that in which information is transmitted by modulating a continuous transmission signal, such as amplifying a signal's strength or varying its frequency to add or take away data

In general, humans experience the world analogically. Vision, for example, is an analog experience because we perceive infinitely smooth gradations of shapes and colors. Most analog events, however, can be simulated digitally.
