Lub topology ntawm computer tes hauj lwm

Cov kev xav ntawm network implies ib tug nram qab no nws txhais. Lub network yog ib tug sau ntawm cov khoom, uas yog tsim los ntawm pab kiag li lawm uas kis thiab cov txheej txheem rau cov ntaub ntawv. International Organization rau standardization cheeb tsam network yog txhais raws li ib tug tshwm sim me ntsis-taw qhia kom paub ntaub ntawv kis tau tus mob system ntawm ywj siab, tab sis interconnected nyob rau hauv ib tug tshwj xeeb txoj kev pab kiag li lawm.

Architecture ntawm computer tes hauj lwm yog hais tias tes hauj lwm feem ntau nyob ib yam cheeb tsam, yog li ntawd lawv feem ntau muab qhia rau ib tug hwv paus. Muaj lub zos, regional thiab ntiaj teb no tes hauj lwm.

Cov kev pab cuam, uas muab networking ntawm tus kheej computers feem ntau muaj peev xwm mus qhia cov kev pab, cov ntaub ntawv sib cais, sib cais ntawm lub software, qhov kev sib cais ntawm CPU kev pab, tau tso ib tug multi-neeg siv hom.

Ntau networking nta muab lub peev xwm los tsim ib tug ntau yam ntawm computer tes hauj lwm classifications. Cov yam ntxwv xws li cov topology ntawm computer tes hauj lwm, lawv lub hom phiaj, daim ntawv teev cov kev pab cuam, tej ntsiab cai ntawm kev tswj (yuav tsum centralized thiab decentralized), switching txoj kev, nkag txoj kev, hom xov xwm kis tau tus mob, cov ntaub ntawv tus nqi , thiab hais txog. N.

Cia peb nyob li ib qho tseem ceeb tswvyim raws li ib tug computer network topology. Nyob rau hauv ib lub computer network, txhua workstation lub cev kev cob cog rua nrog rau lwm cov kev sib txuas lus raws. Cov kev twb kev txuas yog ua raws li ib qho kev qauv, uas yog hu ua tus topology ntawm computer tes hauj lwm. Yog li, lub topology ntawm computer tes hauj lwm yog inherently piav txog lub cev sib txuas nyob rau hauv ib tug computer network uas hais tias ib tug kev ua hauj lwm cov chaw nres tsheb, muaj peev xwm ntawm losis tswvyim dabtsi rau txhua lwm yam. Nyob rau dab tsi hom yog tsiag ntawv los ntawm xaiv topology ntawm computer tes hauj lwm, kev kawm ntawv nyob rau theem ntawm kev khiav hauj lwm efficiency thiab kev cia siab ntawm lub workstations yog networked, raws li zoo raws li lub sij hawm lub sij hawm yuav tsum tau rov hais dua rau cov ntaub ntawv neeg rau zaub mov. Nyob rau hauv tas li ntawd topology muaj ib tug ncaj qha feem nyob rau txoj kev siv cov ntaub ntawv rau lub network, uas yuav tsum muaj ntaub ntawv.

Rau hnub tim ntau yam computer network topologies tsib, tab sis lug siv peb: bus topology, ntiv nplhaib topology, cov topology ntawm lub "hnub qub."

Bus topology yog assumed tias tag nrho cov network ntshav yuav tsum tau txuas nyob rau hauv ib tug ad hoc network los ntawm ib tug tib cable. Cable txiav yuav tsum ua raws li ib tug resistive load. Ib tug tib cable txhawb ib channel cov ntaub ntawv. Lub tsheb npav topology cable hu ua chaw tos tsheb loj. Tes hauj lwm ua nyob rau hauv lub tsheb npav, yog raws li nyob rau hauv lub coaxial cable.

Lub nplhaib topology tau pom nws realization nyob rau hauv tej yam yooj yim phooj ywg computer tes hauj lwm. Tag nrho cov workstations, raws li qhov no topology yog kev cob cog rua nrog nws ob tug nyob ze cov neeg nyob ze. Yog hais tias peb xav txog lub zuag qhia tag nrho kev twb kev txuas daim duab nyob rau hauv lub network uas tsim los ntawm ib tug nplhaib topology, koj yuav saib tau ib yam dab tsi li ib lub nplhaib. Cov ntaub ntawv nyob rau hauv xws tes hauj lwm yuav kis tau nyob rau hauv ib cov kev taw qhia, thiab tag nrho cov workstations khiav lag luam raws li repeaters, uas tau txais thiab teb mus rau lub pob nyob rau lawv, thiab ces hloov cov seem cov ntaub ntawv packets nram qab no ib tug workstation uas yog nyob "downstream".

Cov feem ntau lug siv hnub no tau txais ib lub zos network, ua raws li ib lub hnub qub topology. Nyob rau hauv xws tes hauj lwm, cov ntaub ntawv pab kiag li lawm diverge los ntawm ib qho chaw, muab ib lub hub, ib tug router los yog ib tug network mus. Yog hais tias peb xav txog tej yam lub hub li ib lub hnub qub chaw, ces diverging los ntawm nws yuav zoo li lub rays - li no no topology, thiab tau txais nws lub npe. Lub ntsiab kom zoo dua ntawm ib lub hnub qub topology nyob rau hauv kev sib piv rau lub nplhaib yog tau ib ce muaj zog ntawm sab xis ntawm ywj siab nkag tau mus rau lub network yog muab los ntawm kev ntaus ntawv. Nyob rau hauv cov ntaub ntawv no, txhua ntaus ntawv yog tau thov mus rau lub kis tau tus mob nruab nrab, hais txog ntawm lwm cov pab kiag li lawm nyob rau hauv lub network.
