Digital media refers to electronic media that works on digital codes. Primarily, computing is based on the binary numbering system or base 2. In the binary numbering system, digital refers to the discrete states of the binary numerals 0 and 1. Specific patterns of these base 2 numerals of 0 and 1 represent data or information. Computing machinery, such as a personal computer, interprets binary digital data as information; the prioritized class of digital information processing is represented. There is a fascinating chronology of non-binary digital media and computers also. In essence, digital media like digital audio and digital video can be received and transmitted by digital information processing machines. As a result, digital media represents a dynamic change from analog media.
Moreover, most digital media are based on converting analog data into digital data and vice versa. Nevertheless, digital media can be defined as the creative convergence of business for individual expression, communication, digital arts, education, science, social interaction and technology. This is a list of digital media, based on a technical perspective: compact discs, cell phones, digital televisions, digital videos, e-books, e-commerce, interactive media, the Internet, mini-discs, video games, and the World Wide Web. Hence, the interpretation and represention of digital data and analog data are dependent upon digital media.
Even more so, digital data is relatively simple to manipulate and the end result can be reproduced without any loss of quality. Mathematical operations can be applied to digital data as well. A sequence of digital code like 0100 0111 might be interpreted as the decimal number or base 10 numeral 71, the hexadecimal number or base 16 numeral 47 or the letter G, according to the ASCII Code Table. On the other hand, it is possible to use the same compression operation onto a text file, an image file or a sound file. Thus, the foundations of operation on digital data or information are described in digital signal processing.
Conclusively, in data technology, a digital system uses discrete values. On the contrary, using a continuous range of values to represent information are non-digital or analog systems. Even though digital representations are discrete, the information represented can be discrete like letters, numbers and icons, or continuous like images and sounds. Lastly, the word digital is commonly used in computing and electronics, especially where real world information is converted to binary numeric form like in digital photography.
