电子计算机的发展是衡量一个国家是否现代化的重要标志之一,当前世界上正掀起研制第五代计算机的热潮,据《时代周刊》报导说:“这是区别今后第一流经济强国和第二流经济强国的标志”。美、日等国竞争都很激烈,这就是当前大型机发展的形势。在另一方面计算机向微型机方面发展,其速度比大型机快得多,自从1971年美国Intel公司首先试制成4位微处理机Intel—4004和Mc—4机,引起了世界的震动,发展迅猛,因为微处理机具有体积小、可靠性高,灵活性强、价格便宜,操作系统和软件都便于移植,使用方便,易于普及等等特点,使它向各个方面
The development of computer is one of the most important symbols to measure whether a country is modernized. Nowadays, the craze of developing the fifth generation of computers is being set off in the world. According to Time Magazine, “This is the difference between the first-class economic power and the second class in the future A symbol of economic power. ” The United States, Japan and other countries are fierce competition, which is the current development of the mainframe situation. On the other hand, the development of microcomputers to computers is much faster than that of mainframes. Since 1971, Intel Corporation of the United States first trial-produced four microprocessors Intel-4004 and Mc-4 machines, causing the world’s shock. Rapid development, because the microprocessor has a small size, high reliability, flexibility, low prices, operating systems and software are easy to transplant, easy to use, easy to popularize and so on, so that it to all aspects
