Network operating systems, lawv tus yam ntxwv thiab xaiv

Nyob rau hauv lub rooj plaub uas tus neeg siv cov muaj nyob rau hauv pem hauv ntej ntawm lub pom kev sib cais ntawm network kev pab (piv txwv li - disk qhov chaw), lawv muaj peev xwm siv network operating systems. Tej systems ua rau nws tau mus rau cov hloov ntau administrative zog nyob rau hauv lub network qhov chaw. Nrog kev pab los ntawm network kev pab uas nyob deb tshaj cov neeg siv, cov neeg khiav dej num yog tau tso qhia qhia cov kev pab thiab yog muab ib tug tshwj xeeb lo lus zais rau lawv txhua txhua tus, kom lawv tus kheej muaj thiab siv tau rau txhua tus neeg siv los yog pab pawg neeg ntawm cov neeg. Qhov no division kuj txiav txim seb tus faib ntawm network kev khiav hauj lwm systems nyob rau hauv lub neeg rau zaub mov thiab kev khiav hauj lwm qhov system rau cov neeg siv.

tshwj xeeb network operating systems hnub no, tsim thiab dav siv, tab sis cov uas muaj tus yam ntxwv ntawm peb niaj zaus, kev khiav hauj lwm systems. Tsim tshwj xeeb network operating systems uas muaj qhov tsis muaj cov zoo tib yam, xws li, piv txwv li, ua lub operating system qhov rais xp. Nws yuav tsum tau muab sau tseg tias rau hnub tim, yuav luag tag nrho cov pa tshuab muaj ib tug built-in kev xaiv thiab kev khiav dej num ntawm lub network systems.

Li ntawd, cov network operating system - nws yog zoo li ib qhov system operating, ua-nyob rau hauv los tsis ua cas nta uas tso cai rau koj mus zoo khiav lag luam yog nyob rau hauv ib tug networked qhov chaw. Cov zog muaj xws li:

- muab kev pab txhawb nqa rau ib tug ntau ntawm cov network khoom;

- kev siv cov network twg;

- kom cov kev siv thiab kev pab txhawb nqa ntawm network twg routing;

- filtering ntawm cov tsheb khiav;

- kom ntseeg tau txuas ntxiv nkag tau mus rau tej thaj chaw deb network kev pab (disks thiab printers);

- kev siv ntawm tej thaj chaw deb dlaws rau network cov teeb meem.

Cov feem ntau network operating systems yog: Novell NetWare, txawv versions ntawm lub GNU / Linux operating system, ZyNOS, thiab, ntawm chav kawm, feem ntau Microsoft lub qhov rais (95, NT, XP, Vista, 7).

Niaj hnub nimno network operating systems thiab lawv muaj ntau haiv neeg vim lub fact tias niaj hnub no muaj ntau ntau hom ntawm computers nyob rau hauv lub ntiaj teb no. Uas yog vim li cas, tsim thiab muab nruab rau mobile pab kiag li lawm, lub tsev workstations, neeg rau zaub mov systems, enterprise OS. Nws tus kheej, qhov no faib qhia txog ntau haiv neeg ntawm cov kev ua tau zoo yam ntxwv thiab yeem uas txawv saib kev pab. Qhov no muaj ntau haiv neeg, zoo rau ib sab (yog muab los ntawm tus neeg siv xaiv tus OS mus rau lawv cov nyiaj txiag muaj peev xwm thiab nyob rau hauv raws li cov kev pab raws qib txojkev), tsim tej yam inconveniences, nyob rau lwm yam. Qhov no yooj yim yog qhov yuav tsum tau los xyuas kom meej qhov compatibility ntawm lub operating system, tshwj xeeb tshaj yog rau cov departments ntawm corporations kev khiav hauj lwm nyob rau hauv tib network txoj cai. Ib tug heev ib qho tseem ceeb cov khoom teejtug characterizing ciaj ciam ntawm ib tug network operating system, yog muaj nyob rau thauj cov operating system thiab tau ceev muab kho dua.

Cov feem ntau lug siv operating system nyob rau hauv xws li ib tug ntau yam ntawm tuam txhab uas muag thiab cov tsev, qhov chaw uas qhov kev loj cov ntaub ntawv poob lawm yog yuav tsum tau. Lawm seb puas tsimnyog tau rau lo lus nug ntawm yuav ua li cas xaiv ib tug network operating system zoo kev ua lag ua luam tsis tau siv nyiaj ntxiv. Nws nkawd hais tias lub ntsiab txog kev paub yuav tsum yog tus nram qab no thaum xaiv cov kev tsim nyog operating system. Yog hais tias koj xav tau ib qho chaw loj ntawm ib tug loj lub tuam txhab los yog li, ces xyuam xim rau tej parameter raws li scalability, piv txwv li, ruaj khov lag luam nyob rau hauv ib tug ntau yam ntawm network tej yam kev mob. Nws tseem yog ib qho tseem ceeb thiab ib tug high degree ntawm interoperability - lub peev xwm los zoo siv ua hauj lwm hom ntawm cov hloov tshiab. Nyob rau hauv tas li ntawd, qhov no operating system, nws yog ntshaw yuav tsum xyuas kom meej lub koom ua ke ntawm heterogeneous kev pab - servers thiab computers.

Yeej, nws yog ib qhov nyuaj txaus mus nrhiav thiab xaiv tus operating system uas siab satisfies cov uas yuav tsum tau ntawm ib tug neeg siv. Yog li ntawd, nws yog ntshaw kom nqa tawm lawv txoj kev xaiv raws li ib tug tseem ceeb heev kev luj xyuas ntawm real-lub ntiaj teb no teeb meem thiab qhov teeb meem uas yuav txiav txim rau software.
