Personal computer

pattern of a modern PC

the term personnel computer originating from the English [ˈpɜːsənəl kəmˈpjuːtə] (abbreviation PC), translated „personal computer, is originally manufactured by the company IBM the trade name of a set of computer systems , thosebecame. This concerns determined types of home or personal computers, which is to an individual person at the disposal and can on their needs be adapted.

Originally only IBM computers with of Intel were called processor 8088 „PC “. Today the term firmiertfor the demarcation of the x86 - architecture (IBM-PC compatible computers) in relation to other network architectures, however due to the high spreading synonymously for all commercial computers it is used whereby a term monopoly developed. The term „PC “was thus a trade mark.

first kits

since beginning of the 1970er years were so low-priced computer construction units that enterprises began with the development of computers for private purposes. The first in such a manner computer, which had commercial success, aligned for home users, was the old air 8800 from the year 1974. A whole number of further models, whose most prominent representatives the devices Apple II, followed still as kit sold the old air - family as well as the PET of the company Commodore were.

home computersvs. IBM PC

extended by a television exit and an expenditure for clay/tone came starting from the 80's many further devices than home computers so mentioned on the market. Examples of it are later the usually-sold home computer Commodore C64 and the devices the Amiga - row, thanalso different versions of the Atari pc.

Particularly the success and the innovative architecture Apple of the II alarmed IBM, the market leader at that time with (large) computers and electrical typewriters. 1981 presented, modular developed IBM-PC was as direct competition product in addition conceived. OverDevelopment time and - to save, deviated IBM cost from its practice at that time to manufacture a majority of the components themselves. Instead most construction units were bought to go with, among other things the operating system (MS-DOS of Microsoft, of IBM sold as PC DOS) and the processor (Intel 8088).

The IBM-PC was initially in regard to audio abilities and diagram technically far underlaid for the home computers and rightfully high prices was originally sold. However IBM did not have a monopoly on the used components (with exception of the BIOS). So Compaq 1983 could bring compatible PC to first IBM on the market. Clones, thus copying, different hardware components developed in the Far East to a proper people sport. Thus fast a market of IBM developed - reproductions, thatby the competition to sinking prices and intensified innovation led. Within one decade the PC displaced the home computers also within the private sector, only Apple created it to hold further a portion worth mentioning. All other manufacturers disappeared to a large extent from the market (Commodore) or turned again different business fields too (Atari, cutter). The more current PC models of IBM, like the PC 300GL remained as far as possible unknown, and went down on the market of the clones. Similarly it was issued the attempt ofIBM, the market with that personnel System/2 - row and the operating system OS/2 zurückzuerorbern.

In the private sector home computers and PC were used first for experimenting , learning and playing. They became later for text processing (WordPerfect), data bases (Dbase) and Spread-sheet analysis (VisiCalc) assigned, so that they found also entrance into the operational everyday life.

modern trend PC

today PC (- reproductions) is very efficiently and almost universally operational. Usually IBM-compatible PCs are used on x86 - basis. Ofin the year 2004 only the Apple Macintosh remained remaining for the other earlier network architectures for single place computers and than niche product Amiga /Pegasos. These are performance-related using modern operating systems such as Mac OS X, LinuxPPC or MorphOS with thatnumerous IBM-compatible PC clones comparably. Still systems on RISC OS are isolated - to basis (arm CCU).
