当前,我国各行各业都在日益广泛地开展计算机技术的推广和应用,其水平也在不断提高,对计算机的需求量也越来越大。由于价格便宜,使用灵活方便、维护管理简便等优点,而得到推广和普及。但是,微型机毕竟受到内存容量小和速度低的限制,在许多方面都不可能取代大中型机,例如复杂的科学与工程计算,大型数据库和专家系统和计算机通讯网络的建立等等,微型机就无能为力,必须依靠中型或大型计算机系统。许多大专院校、科研机构、国家机关、大型企事业单位等,已经或者打算配置具有一定规模的大中型计算机系统(一般加法运算速度100万次/秒以上),并在此基础上建立计算中心,这样大大促进其事业的发展。
At present, all walks of life in our country are carrying out the popularization and application of computer technology more and more extensively, and its level is also constantly improving, and the demand for computers is also growing. As a result of cheap, flexible and convenient to use, maintenance and management advantages of convenience, which have been promoted and popularized. However, after all, microcomputers are limited by the small memory capacity and low speed, and it is impossible to replace large and medium-sized machines in many aspects such as complicated scientific and engineering calculations, establishment of large-scale databases and expert systems and computer communication networks, You can not do anything, you have to rely on medium or large computer systems. Many universities and colleges, scientific research institutes, state organs, large enterprises and institutions, etc., already have or plan to allocate medium- and large-scale computer systems with a certain scale (general addition speed is over 1 million times per second) and establish a computing center , So greatly promote the development of its cause.
