九十年代以来,多媒体电脑成为信息技术领域的热门话题。消费者逐渐把眼光由渴望拥有一部个人电脑,变为渴望拥有一部多媒体个人电脑。但若要做出合理明智的选择,必须充分理解和认识多媒体电脑的基本常识。 多媒体技术是以数字技术为基础,把声音、图像等模拟信号转化成数字信号后进行处理,从而达到集多种信息于一身的系统。固为数字信号在传输和处理过程中不易出错,所以,以此为基础的多媒体电脑所处理的声音和图像比模拟设备处理的声音和图像具有更高的保真度。多媒体电脑是融合了通信技术(电话、传真)、传播技术(广播、电视)和电脑技术的一种高科技产物,也可处理文
Since the nineties, multimedia computers have become a hot topic in the field of information technology. Consumers are gradually changing their vision from wanting to own a personal computer to aspiring to own a multimedia personal computer. However, to make a reasonable and wise choice, the basic common sense of multimedia computers must be fully understood and understood. Multimedia technology is based on digital technology, the sound, images and other analog signals into digital signals for processing, so as to achieve a set of information in a system. Solid-state digital signals are not prone to errors during transmission and handling, so the multimedia computers on which they are based handle the sounds and images with greater fidelity than the sound and images processed by the analogue devices. Multimedia computers are a high-tech product that combines communication technologies (telephone, fax), communication technologies (radio, television) and computer technology, as well as
