一、概述信息输入是当前计算机应用中的薄弱环节,我们把信息输入定义为从被控对象的感受件开始,直至控制计算机输入通道的接口寄存器为止。它由二部分组成,即计算机的过程通道和现场的联接系统。应用程序是建立在从通道接口寄存器中获取数据的基础上的,输入系统工作不好,不仅限制计算机的 First, an overview of information input is the current weaknesses in computer applications, we define the information input from the controlled object of the feelings of the beginning until the control of computer input channel interface register so far. It consists of two parts, namely, the process of computer access and on-site connection system. The application is based on getting data from the channel interface register, the input system does not work well, not only restricts the computer’s
