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、Exabyte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。
The constant increase of CPU speed, the continuous updating of related software, and the wide application of multimedia and network technologies, the Internet has become a global information exchange network. All of this shows that computer technology is developing at a high speed and it also shows that human information technology is taking place. New changes. As an input-output device in information processing, external equipment also undergoes rapid and dramatic changes, and its new series is continuously derived. However, its technological innovation and development may not be well-known. Therefore, in order to popularize this knowledge, in order to allow the majority of readers to better understand the composition, function and development of external devices from a technical perspective. This publication has opened up special technical columns for external equipment and elaborated the current status and development of external equipment from a technical perspective. The companies participating in the co-hosting work during this period include: Shante Company, Zhongjing Company, Logitech Corporation, Exabyte Corporation, and Canon Corporation. We are grateful for their positive efforts. Participate and work together to make this technical column better and better.
