Add to basketDruck auf Anfrage Neuware - Printed after ordering - UNIX ist ein dialogorientiertes Mehrbenutzer-Betriebssystem. Es wurde in den frü hen 70er Jahren an den Bell Laboratories für Systeme der Serie DEC PDP-}} ent wickelt. Die Mitte 70er Jahre fertiggestellte Version von UNIX konzentrierte seine zielsystemspezifischen Teile auf einen relativ kleinen Kern. Damit öffnete sich UNIX der Weg für einen Einsatz auf breiter Front, wie er nur für ein herstellerun abhängiges Betriebssystem denkbar ist. Die enorme Verbreitung begann sich vor erst an Universitäten sowie an Forschungs-und Entwicklungslabors bemerkbar zu machen, wobei UNIX bis in die späteren 70er Jahren noch meist auf Systemen DEC PDP-}} eingesetzt wurde. Seit den frühen 80er Jahren erfreut sich UNIX zu nehmender Beliebtheit auf Mikros, Minis und Großrechnern verschiedenster Her steller. Heute kann eindeutig ein Einsatzschwerpunkt auf Mehrplatzsystemen der unteren und mittleren Leistungsklasse festgestellt werden. Es fällt recht schwer, alle Gründe zu nennen, die zu der respektablen Verbreitung von UNIX geführt haben. Die am meisten genannten Faktoren können aber in vier Punkte zusammengefaßt werden: UNIX stammt nicht von einer Computerfirma und ist nicht an einen bestimm ten Rechner gebunden. Dieser Umstand zusammen mit der im Vergleich zu an deren Betriebssystemen relativ hohen Portabilität bewegte viele Hardwareher steller, UNIX auf ihre Systeme zu adaptieren, statt ein eigenes Betriebssystem zu entwerfen und zu realisieren. Dadurch entstand eine über viele Computerfa milien hinweg einheitliche Systemoberfläche. UNIX wird somit für den Softwa reentwickler zu einer sehr attraktiven Entwicklungsgrundlage, sind doch seine Produkte damit nicht mehr nur auf wenigen Systemtypen verfügbar, sondern auf einer herstellerunabhängigen Betriebssystemoberfläche.
