The history of microcomputers is not going to compare with the track record of ancient Mesopotamia (Iraq). Microcomputers (now commonly held as PCs) were around for only 24? 30 years.
It is good to experience some knowledge of this history both to allow some perspective of where our company is today and to know where a variety of our basic computer standards that we miss? as if they originated heaven, originated.
The primary microcomputer machines were as exciting in the form of do-it yourself set? a thrill if you ever were the type who forever liked to tinker with circumstances to make them work..
Early computer systems (or micococomputers as these folks were first called lacked a right standard. The computer chips makers? Intel, Motorola and Zilog - all competed while in the microprocessor (CPU) in a good rash of different pc's from different manufactures. None were works with any others.
IBM抯 introduction of your real IBM PC inside August 1981 opened the eyes of a lot. IBM had scores connected with sales representatives with credibility who have been well entrenched in corporations and businesses everywhere.
The IBM sales staff members? used to selling huge ticker items and invoicing millions of dollars? well dressed up in 揑BM Blue? three article suits, were well comfortable with corporate life and power structures when using the 搈overs and shakers? who seem to counted.
IBM opened their own personal stores selling all IBM hardware and their own brand for software. The software were written by third parties and adapted for those PC- DOS (IBM憇 proprietary version on the Microsoft Operating System DOS purchased under license). IBM insisted that the many software be packaged in the identical standard plain white cases with identical blue brands.
A number of companies did start to produce machines that implemented the MS-DOS (Microsoft DOS) main system. In the beginning, we were looking at similar to PC-DOS products, but were not thoroughly compatible? software for PC-OS would seldom train on an MS-DOS machine together with vice 杤ersa. Somewhere en route however the 2 merged so that in fact there was little distinction amongst the two operating systems? IBM PC-DOS plus Microsoft MS-DOS. Hence the IBM compatible computes (clones) in addition to genuine IBM computers would both run similar software properly.
IBM kept the pressure on featuring its next system release, a 6 MHz PC/AT, the earliest machine to use Intel抯 subsequent generation chip the 80286 CPU..
However, these first generation ATs were tormented by frequent hard disk failures. Without any warning, a user抯 disk may fail and important and essential data is lost. The problem was thus widespread that IBM clones manufacturers begun to erode IBM抯 market prominence.
This went on when the clone competition continually much better their products. As effectively PC clones were extensively cheaper than IBM抯 machines, with larger hard hard drives (from 40 megabytes that will even the unbelievable 100). More significant memory became standard, and options just like built in serial together with parallel ports were combined with system boards. As effectively clones often included screens, display adapters and software package in attractively priced packages.
The PC/AT continued selling well, but IBM抯 market share begun to erode, even though it was initially selling more machines than any other time. Other clone manufacturers (Compaq and additionally Advanced Logic Research meant for example) moved quickly relating to Intel抯 next big microprocessor introductions.
The die was set in place. The IBM PC set the standards although the clone manufacturers forever dominated the industry which IBM had created and lost.
