“数字化”的过程 ,涉及到数字的转换、存取、处理、传输、控制、压缩等一系列高新技术 ,它是半导体技术、光纤技术、无线电技术、计算机及其软件技术等一群高新技术综合发展所引起的信息技术革命。离开了数字化技术 ,就说不上信息技术及其革命 ,也就不可能在信息高速公路上编 The process of “digitization” involves a series of high and new technologies such as digital conversion, access, processing, transmission, control and compression. It is a group of high-tech comprehensive development of semiconductor technology, optical fiber technology, radio technology, computer and software technology Caused by the information technology revolution. Without digital technology, it is impossible to say information technology and its revolution, it is impossible to make in the information superhighway
