所谓数字媒体,包括两方面的涵义:一是指信息的载体,即以不同于以往的模拟信号、而以非连续的数字形式存在的一种叫做“比特”的电子符号为载体、全方位交互传播信息的计算机装置;二是指被传递的内容,即以“比特”作为最小信息单位的信息本身。所谓“比特”,是相对于传统媒体中实物信息载体的“原子”而言的,比特没有形状和质量。 The so-called digital media, including two meanings: First, refers to the carrier of information, that is different from the analog signal in the past, but in a non-continuous digital form exists as a “bit” of electronic symbols as a carrier, full interactive The computer device that disseminates information; the second is the content that is conveyed, namely the information itself with “bit” as the smallest unit of information. The so-called “bit” is relative to the “atom” of the physical information carrier in the traditional media. The bit has no shape or quality.
