CPU速度的不断提高,相关软件的不断更新,多媒体、网络技术广泛的应用,Internet成为全球信息交互网,所有的一切都表明:电脑技术正在高速发展,同时也显示着人类信息技术正在发生一场新的变革。作为信息处理中的输入输出设备——外部设备也同样发生着迅速而巨大的变化,其新品系列不断派生,然而它的技术创新和发展可能并不为人熟知。因此为了普及这方面知识,为了让广大读者能更好的从技术上了解外部设备的组成、功能及其发展。本刊特开辟外部设备技术专栏,从技术角度阐述外部设备的现状和发展,本期参加协办投稿的单位有:山特公司、中晶公司、罗技公司、Exabye公司、佳能公司,我们感谢他们的积极参与,并共同把这个技术专栏越办越好。
With the continuous improvement of CPU speed, continuous updating of relevant software, extensive application of multimedia and network technology, the Internet has become a global information exchange network. All this shows that the rapid development of computer technology is also showing that human information technology is taking place New change. As an input and output device in information processing - external devices also undergo rapid and dramatic changes, new series derived continuously, but its technological innovation and development may not be well known. Therefore, in order to popularize this knowledge, in order to enable readers to better understand the technical composition of the external device, function and development. We hereby open up a special column of external equipment technology to expound the current situation and development of external equipment from a technical point of view. The units that participated in this issue are: Santak, Zhongjing, Logitech, Exabye, Canon, and we thank them for their enthusiasm Participate, and work together to improve the technical column.
