微机(个人计算机Personal Computer)的制作是非专门家莫属之事,但微机的操作却是一般外行也可以掌握自如的。正因为微机不难被掌握,且在被掌握、被认识的过程中人们又不断向它提出新的要求,所以才有频繁的革命。微机革命当然首先明显地表现于硬件方面,仅以中国长城(GW)0520系列微机为例,据我所知近几年来就有GW0520B、GW0520A、GW0520C、GW0520CH、GW0520EM、GW0520DH等陆续问世,其中GW0520EM是IBM-PC/XT的兼容机。日本微机市场上硬件的变化更是令人目不暇接,其更新换代的速度之快起码可说是以月来计算的。各国微机硬件变化的主要特点都是微型化、高速化及存储容量的扩大。计算机从1945年问世,至今才50年的历史,它的成长,相当于人类社会几十个世纪的变化。
The production of a microcomputer (Personal Computer) is a non-expert, but the operation of a microcomputer is generally outside the control of a worker. It is precisely because the microcomputer is not difficult to grasp, and in the process of being mastered and recognized, people constantly make new demands to it so that there are frequent revolutions. Of course, the computer revolution is obviously manifested in the hardware. Only the Great Wall GW520 series microcomputer is taken as an example. As far as I know, GW0520B, GW0520A, GW0520C, GW0520CH, GW0520EM and GW0520DH have come out one after another in recent years. GW0520EM IBM-PC / XT compatible. Japan’s computer market changes in the hardware is more dizzying, the speed of its replacement at least can be said to be calculated on a monthly basis. The main features of computer hardware changes in various countries are miniaturization, high speed and storage capacity expansion. Since the advent of the computer in 1945, it has only 50 years of history. Its growth is equivalent to that of the human society over the past decades.
