Digital media (as opposed to analog media) usually refers to electronic media that work on digital codes. Today, computing is primarily based on the binary numeral system. In this case digital refers to the discrete states of “0″ and “1″ for representing arbitrary data. Computers are machines that (usually) interpret binary digital data as information and thus represent the predominating class of digital information processing machines. Digital media (“Formats for presenting information” according to Wiktionary:Media) like digital audio, digital video and other digital “content” can be created, referred to and distributed via digital information processing machines. Digital media represents a profound change from previous (analog) media.

Digital data is per se independent of its interpretation (hence representation). An arbitrary sequence of digital code like “0100 0001″ might be interpreted as the decimal number 65, the hexadecimal number 41 or the glyph “A”. See also: ASCII, Code.

Florida’s digital media industry association, Digital Media Alliance Florida, defines digital media as “the creative convergence of digital arts, science, technology and business for human expression, communication, social interaction and education”.

The transformation of an Analog signal to Digital information via an Analog-to-digital converter is called sampling. According to information theory, sampling is a reduction of information. Most digital media are based on translating analog data into digital data and vice-versa.
