PostSubject: A history Of Microcomputers.   Fri Oct 14, 2011 1:52 pm

The history of microcomputers fails to compare with the the past of ancient Mesopotamia (Iraq). Microcomputers (now commonly held as PCs) were around for only 24? 30 years.

It is good to have some knowledge of this history both to provide some perspective of where our company is today and to know where a variety of our basic computer standards that we skip over? as if they originated in heaven, originated.



The primary microcomputer machines were as exciting as a do-it yourself set? a thrill if you ever were the type whom forever liked to tinker with circumstances to make them work..

Early computer systems (or micococomputers as these folks were first called lacked a clear standard. The computer computer chip makers? Intel, Motorola and Zilog - all competed while in the microprocessor (CPU) in a good rash of different pc systems from different manufactures. None were works with any others.

IBM抯 introduction of your real IBM PC for August 1981 opened the eyes of a lot of. IBM had scores regarding sales representatives with credibility who have been well entrenched in corporations and businesses everywhere.

The IBM sales staff members? used to selling giant ticker items and invoicing millions of dollars? well dressed up in 揑BM Blue? three chunk suits, were well comfortable with corporate life and power structures considering the 搈overs and shakers? who seem to counted.

IBM opened their personal stores selling all IBM hardware and their own brand about software. The software has been written by third parties and adapted for the PC- DOS (IBM憇 proprietary version with the Microsoft Operating System DOS distributed under license). IBM insisted that the many software be packaged in the identical standard plain white containers with identical blue marking.

A number of companies began to produce machines that utilized the MS-DOS (Microsoft DOS) os. In the beginning, we were looking at similar to PC-DOS equipment, but were not totally 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 guarantees there was little distinction between your two operating systems? IBM PC-DOS plus Microsoft MS-DOS. Hence the IBM compatible computes (clones) and also genuine IBM computers would both run the exact same software properly.

IBM kept the pressure on featuring its next system release, a 6 MHz PC/AT, the earliest machine to use Intel抯 so next generation chip the 80286 PROCESSOR..

However, these first generation ATs were tormented by frequent hard disk downfalls. Without any warning, a user抯 disk would fail and important and essential data is lost. The problem was for that reason widespread that IBM clones manufacturers begun to erode IBM抯 market prominence.

This went on given that the clone competition continually increased their products. As effectively PC clones were substantially cheaper than IBM抯 models, with larger hard hard disks (from 40 megabytes in order to 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 shows, display adapters and software package in attractively priced bundles.

The PC/AT continued selling well, but IBM抯 market share begun to erode, even though it was initially selling more machines than before. Other clone manufacturers (Compaq and Advanced Logic Research meant for example) moved quickly concerning Intel抯 next big microprocessor introductions.

The die was set. The IBM PC set the standards although the clone manufacturers forever dominated market trends which IBM had developed and lost.
