多年来,我国的计算机资源都是属于部门专有。单用户方式使用,多数用于科学计算,效率极低,资源浪费严重。扩大计算机应用领域,从单纯进行科学计算中解脱出来,改变应用方式,使计算机朝社会化、网络化、远程化方向发展,已成为国内计算机界的一个必然趋势。 DJS130多用户服务系统,又称单处理机中的网终络,是以DJS130为中心机,网状分布终端的(?)机系统。它在用户驻地设置终端,利用室内电话交换网实现终端与计算机的数据通讯,突破了计算机应用的地理和空间条件的限制。在多用户扩展BASIC软件的 Over the years, China’s computer resources are part of the departmental. Single-user use, most for scientific computing, low efficiency, serious waste of resources. It has become an inevitable trend in the computer field to expand the field of computer applications, to free itself from purely scientific calculation, to change the way of application, and to make computers develop toward socialization, networking and remoteness. DJS130 multi-user service system, also known as single-processor network in the network, is based on DJS130 as the center machine, network distribution terminal (?) Machine system. It set up the terminal in the user premises, the use of indoor telephone switching network terminal and computer data communications, breaking the computer application of the geographical and spatial conditions.
