PostSubject: A brief history Of Microcomputers.   Fri Oct 14, 2011 1:19 pm

The history of microcomputers would not compare with the track record of ancient Mesopotamia (Iraq). Microcomputers (now commonly held as PCs) are already around for only 25? 30 years.

It is good to acquire some knowledge of this history both to allow some perspective of where we are today and to know where several our basic computer standards that we miss? as if they originated heaven, originated.



The earliest microcomputer machines were as exciting for a do-it yourself set? a thrill in the event you were the type so, who forever liked to tinker with what you should make them work..

Early pcs (or micococomputers as we were looking at first called lacked an apparent standard. The computer chips makers? Intel, Motorola and Zilog - all competed inside the microprocessor (CPU) in a rash of different pc's from different manufactures. None were suitable for any others.

IBM抯 introduction with the real IBM PC within August 1981 opened the eyes for many. IBM had scores about sales representatives with credibility who have been well entrenched in corporations and businesses around the globe.

The IBM sales workers? used to selling large ticker items and invoicing thousands of dollars? well dressed in 揑BM Blue? three element suits, were well used to corporate life and power structures together with the 搈overs and shakers? which counted.

IBM opened their own personal stores selling all IBM hardware along with their own brand associated with software. The software ended up being written by third parties and adapted for any PC- DOS (IBM憇 proprietary version for the Microsoft Operating System DOS offered for sale under license). IBM insisted that each of the software be packaged in the very same standard plain white box with identical blue marking.

A number of companies begun to produce machines that made use of the MS-DOS (Microsoft DOS) computer system. In the beginning, we were holding similar to PC-DOS makers, but were not well compatible? software for PC-OS would seldom run using an MS-DOS machine and vice 杤ersa. Somewhere as you go along however the 2 merged so that all things considered there was little distinction amongst the two operating systems? IBM PC-DOS and also Microsoft MS-DOS. Hence both the IBM compatible computes (clones) and additionally genuine IBM computers would both run precisely the same software properly.

IBM kept the pressure on having its next system release, the particular 6 MHz PC/AT, the initial machine to use Intel抯 following generation chip the 80286 CENTRAL PROCESSING UNIT..

However, these first generation ATs were affected by frequent hard disk suprises. Without any warning, a user抯 disk would probably fail and important and essential data could be lost. The problem was therefore widespread that IBM clones manufacturers begun to erode IBM抯 market prominence.

This went on as being the clone competition continually advanced their products. As very well PC clones were drastically cheaper than IBM抯 makers, with larger hard hard disk drives (from 40 megabytes that will even the unbelievable 100). Better memory became standard, and options for instance built in serial and parallel ports were included in system boards. As very well clones often included screens, display adapters and application in attractively priced packages.

The PC/AT continued to offer well, but IBM抯 market share began to erode, even though it was selling more machines than any other time. Other clone manufacturers (Compaq plus Advanced Logic Research for example) moved quickly for Intel抯 next big microprocessor introductions.

The die was placed. The IBM PC set the standards nevertheless the clone manufacturers forever dominated this marketplace which IBM had designed and lost.
