微机诞生之初,各厂家都是按照自己的标准设计和生产的,不同厂家的软、硬件产品都不能相互支持,给用户的选择带来了极大的困难,反过来阻碍了微机产业的发展.1981年,世界最大的计算机厂家IBM公司涉足微机领域,推出了具有划时代意义的IBM PC机,结束了微机则界杂乱无章的时代.IBM公司以IBM PC这个产品制订了一套完整而开放的微机体系结构标准.由于IBM实力雄厚,此标准制订得非常完善,加之IBM对外开放,别的厂商就纷纷根据此标准设计、制造自己的微机和外设产品.这些产品由于都遵照IBM制订的标准,因此可以在软、硬件上相互支持,极大地方便了用户对微机产品的选择,反过来推动了微机产业的发展.逐渐地,不符合IBM标准的微机被淘汰了,符合IBM标准的微机生存下来并发展壮大,形成规模宏大的PC产业.在世界微机市场中,符合IBM标准的微机占绝大多数.
Microcomputer was born, the manufacturers are in accordance with their own standards for the design and production of different manufacturers of hardware and software products can not support each other to the user’s choice has brought great difficulties, which in turn impede the development of computer industry In 1981, IBM, the world’s largest computer manufacturer, set foot in the field of microcomputer and launched the epoch-making IBM PC, ending an era of disorganization in the micro-computer industry.IBM developed a set of complete and open microcomputer with this product of IBM PC The standard of architecture.Because of the strength of IBM, this standard is developed very well, and IBM is open to the public, other manufacturers have designed and manufactured their own microcomputers and peripheral products according to this standard.As these products comply with the standards set by IBM, So you can support each other software and hardware, which greatly facilitates the user’s choice of computer products, which in turn promote the development of computer industry.Often, IBM does not meet the standard microcomputer was eliminated, in line with IBM standard microcomputer survive And the development and growth, the formation of large-scale PC industry in the world of computer market, in line with the IBM standard computer accounted for the overwhelming majority.
