Puas yog lub hub thiab lub adapter yog tib yam?**
** Taw qhia
Thaum nws los txog rau khoos phis tawj kho vajtse, muaj ntau yam khoom siv thiab cov khoom siv uas ua haujlwm sib txawv. Ob yam khoom siv no yog hub thiab adapter. Txawm hais tias lawv yuav zoo sib xws thaum xub thawj siab ib muag, muaj qhov sib txawv tseem ceeb ntawm ob. Hauv tsab xov xwm no, peb yuav tshawb txog cov haujlwm, cov yam ntxwv, thiab kev siv ntawm ob lub hubs thiab adapters, thiab tsim kom pom seb lawv puas yog tib yam lossis tsis yog.
Nkag siab Hubs
Ib lub hub, nyob rau hauv cov ntsiab lus ntawm kev sib txuas hauv computer, yog ib qho khoom siv kho vajtse uas ua lub hauv paus kev sib txuas rau ntau yam khoom siv hauv cheeb tsam hauv cheeb tsam network (LAN). Nws lub luag haujlwm tseem ceeb yog kom tau txais cov ntaub ntawv pob khoom los ntawm ib lub cuab yeej thiab tshaj tawm lawv mus rau tag nrho lwm cov khoom siv sib txuas. Hubs ua haujlwm ntawm lub cev txheej (Txheej Txheej 1) ntawm OSI qauv, txhais tau tias lawv ua haujlwm nrog cov ntaub ntawv nyoos thiab tsis ua cov ntaub ntawv ua haujlwm lossis lim dej.
hubs feem ntau muaj ntau qhov chaw nres nkoj kom haum rau ntau yam khoom siv. Tus naj npawb ntawm cov chaw nres nkoj tuaj yeem sib txawv nyob ntawm seb hom hub, xws li los ntawm ob peb mus rau ntau lub kaum os. Thaum ib pob ntawv ntawm cov ntaub ntawv tau txais ntawm ib qho chaw nres nkoj, nws tsuas yog duplicated thiab xa mus rau tag nrho lwm cov chaw nres nkoj, tso cai rau txhua qhov txuas txuas tau txais cov ntaub ntawv ib txhij.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias hubs tau suav tias yog cov cuab yeej cuab tam qub thiab tau hloov pauv los ntawm cov khoom siv sib txuas ntau dua xws li cov keyboards thiab routers. Hubs raug kev txom nyem los ntawm ntau qhov kev txwv, suav nrog kev sib koom ua ke hauv network, txo qis bandwidth faib, thiab siv tsis tau cov peev txheej hauv network.
Cov yam ntxwv ntawm Hubs
- Kev tshaj tawm: Raws li tau hais dhau los, hubs tshaj tawm cov ntaub ntawv xa tuaj rau txhua yam khoom siv txuas nrog tsis muaj kev ntxub ntxaug. Qhov tsis muaj kev lim dej no tuaj yeem ua rau cov tsheb tsis tsim nyog hauv lub network thiab txo qis kev ua haujlwm tag nrho.
- Cov Khoom Siv Lub Cev Lub Cev: Cov hubs ua haujlwm ntawm lub cev txheej ntawm OSI qauv, txhais tau hais tias lawv feem ntau cuam tshuam nrog hluav taws xob lossis kho qhov muag teeb liab thiab tsis ua ib qho laj thawj lossis cov ntaub ntawv cuam tshuam.
- Tsawg Kev Txawj Ntse: Hubs yog cov khoom siv yooj yim nrog kev txawj ntse tsawg. Lawv tsis muaj kev paub txog cov khoom siv txuas nrog '' IP chaw nyob lossis MAC chaw nyob, ua rau lawv tsis tuaj yeem xa cov ntaub ntawv mus rau cov khoom siv tshwj xeeb zoo.
Nkag siab Adapters
Ib qho adapter, tseem hu ua dongle, yog ib qho khoom siv uas tso cai rau kev sib txuas ntawm cov khoom siv sib txawv lossis cov khoom siv sib txuas rau lub computer lossis lwm yam khoom siv hluav taws xob. Adapters ua haujlwm nruab nrab ntawm cov khoom siv uas tsis muaj kev sib txuas lossis kev sib txuas. Lawv feem ntau tuaj nyob rau hauv daim ntawv ntawm cov khoom siv sab nraud me me uas tuaj yeem txuas tau yooj yim rau hauv cov chaw nres nkoj sib xws ntawm cov khoom siv uas lawv npaj yuav txuas.
Adapters tuaj yeem ua ntau hom nyob ntawm lawv lub hom phiaj. Qee hom adapters muaj xws li USB adapters, HDMI adapters, Ethernet adapters, thiab suab adapters. Txhua lub adapter yog tsim los hloov ib hom kev sib txuas lossis kev sib txuas mus rau lwm qhov, tso cai rau cov khoom siv sib txuas lus thiab ua haujlwm ua ke seamlessly.
Nta ntawm Adapters
- Interface Conversion: Lub luag haujlwm tseem ceeb ntawm tus adapter yog hloov ib hom kev sib txuas lossis kev sib txuas rau lwm qhov. Piv txwv li, USB adapter yuav tso cai rau kev sib txuas ntawm USB-A ntaus ntawv mus rau ib lub cuab yeej uas tsuas yog USB-C chaw nres nkoj.
- Device Compatibility: Adapters ua kom muaj kev sib raug zoo ntawm cov khoom siv uas muaj cov sib txuas sib txawv lossis kev sib txuas. Qhov kev ua tau zoo no tso cai rau cov neeg siv txuas thiab siv cov khoom siv uas yuav tsis sib xws lossis xav tau kev hloov kho kho vajtse ntxiv.
- Compact thiab Portable: Adapters feem ntau me me, hnav, thiab portable. Lawv tuaj yeem nqa tau yooj yim thiab siv nrog cov khoom siv sib txawv, ua rau lawv yooj yim rau kev mus los lossis cov xwm txheej uas ntau yam khoom siv yuav tsum tau txuas nrog.
Qhov sib txawv ntawm Hubs thiab Adapters
Thaum ob lub hubs thiab adapters ua haujlwm nruab nrab ntawm cov khoom siv, muaj qhov sib txawv tseem ceeb ntawm ob:
- Muaj nuj nqi: Hubs feem ntau ua raws li lub hauv paus kev sib txuas cov ntsiab lus rau ntau yam khoom siv hauv lub network thiab tshaj tawm cov ntaub ntawv rau txhua yam khoom siv sib txuas. Adapters, ntawm qhov tod tes, pab txhawb kev sib txuas ntawm cov khoom siv nrog sib txawv interfaces lossis connectors.
- Txheej txheej ua haujlwm: Hubs ua haujlwm ntawm lub cev txheej ntawm OSI qauv, cuam tshuam nrog cov ntaub ntawv raw cov ntaub ntawv. Adapters ua haujlwm ntawm cov khaubncaws sab nraud povtseg siab dua, hloov pauv ntawm qhov sib txawv interfaces lossis cov khoom sib txuas.
- Kev tuav ntaub ntawv: Hubs tshaj tawm cov ntaub ntawv mus rau tag nrho cov khoom siv sib txuas, ua rau muaj kev sib koom ua ke ntau ntxiv thiab siv tsis tau cov peev txheej hauv lub network. Adapters, txawm li cas los xij, tsis hloov cov ntaub ntawv raug xa tawm tab sis txhais nws mus rau hauv hom sib xws rau cov khoom tau txais.
- Ntaus Compatibility: Hubs tsis daws cov teeb meem kev sib raug zoo ntawm cov cuab yeej. Adapters, ntawm qhov tod tes, yog tsim tshwj xeeb los daws teeb meem kev sib raug zoo los ntawm kev hloov cov interfaces lossis cov khoom sib txuas.
Xaus
Hauv kev xaus, hubs thiab adapters tsis yog tib yam. Thaum ob lub cuab yeej ua haujlwm ua haujlwm nruab nrab ntawm cov khoom siv, lawv cov haujlwm, cov yam ntxwv, thiab kev siv sib txawv heev. hubs ua raws li lub hauv paus kev sib txuas cov ntsiab lus rau cov khoom siv hauv lub network, tshaj tawm cov ntaub ntawv mus rau txhua yam khoom siv sib txuas tsis sib xws. Adapters, ntawm qhov tod tes, pab kev sib txuas ntawm cov khoom siv sib txawv los yog cov khoom sib txuas, tso cai rau lawv sib txuas lus thiab ua haujlwm ua ke seamlessly. Kev nkag siab txog qhov sib txawv ntawm hubs thiab adapters yog qhov tseem ceeb rau kev teeb tsa thiab tswj xyuas cov khoos phis tawj sib txuas thiab txuas cov khoom siv sib txawv uas yuav tsum muaj kev sib txuas.
