Sieťový operačný systém

Všeobecné vlastnosti sieťového OS druh operačného systému, ktorý je určený na prácu v počítačovej sieti môže pracovať buď samostatne ako jediný operačný systém na stanici alebo ako súčasť inštalovaného operačného systému spravidla má dve časti : serverovú a klientsku

Všeobecné vlastnosti sieťového OS Na serveri beží výhradne serverová časť sieťového operačnéhp systému na klientskej stanici potom môže ako súčasť lokálneho operačného systému pracovať modul „klient“, ktorý je súčasťou sieťového operačného systému klient zabezpečuje nízkoúrovňové služby pre lokálny operačný systém, pomocou ktorých dokáže tento OS komunikovať v počítačovej sieti.

Základné úlohy sieťového OS smerovanie toku dát medzi serverom a klientskou stanicou riadenie prístupu v súvislosti s definovanými bezpečnostnými požiadavkami neporušiteľnosť dát pri súčasnom prístupe viacerých užívateľov komunikáciu medzi sieťovými užívateľmi spojenie medzi rôznymi sieťami

Druhy sieťových OS Windows NT for server Windows NT for Workstation Windows Server 2003 Windows Server 2008 Novell Netware 6.5 Unix Linux
