Raws li cov qauv thiab kev faib ua haujlwm, hubs tuaj yeem muab faib ua peb pawg: cov hubs tsis muaj kev tswj hwm, cov hubs stacked, thiab chassis hubs.
(1) Unmanaged hub
Lub hub yooj yim tshaj plaws muab kev sib txuas hauv nruab nrab ntawm lub tsheb npav Ethernet, txuas nrog lub hnub qub. Qhov no yog hu ua lub hub uas tsis tau tswj hwm thiab tsuas yog siv hauv cov tes hauj lwm me me uas muaj txog li 12 nodes (nyob rau qee kis, yuav xav tau ntau dua). Unmanaged hubs tsis muaj kev tswj hwm software lossis cov txheej txheem los muab kev tswj xyuas network. Cov hubs no tuaj yeem ua tsis tau lossis ua haujlwm, thiab cov hubs nquag siv ntau dua.
(2) Stacked Hub
Ib tug stacked hub yog ib tug me ntsis complex hub. Qhov tseem ceeb tshaj plaws ntawm lub hub stacked yog tias yim transceivers tuaj yeem txuas ncaj qha rau ib leeg. Txoj kev no, tsuas yog ntxiv lub hub thiab txuas mus rau lub hub uas twb tau teeb tsa tuaj yeem nthuav dav lub network, uas tsis yog tsuas yog siv nyiaj xwb tab sis kuj yooj yim thiab yooj yim rau kev siv.
(3) Chassis hub
Lub chassis hub yog ib qho khoom siv modular uas tuaj yeem ua raws li ntau hom modules ntawm nws lub motherboard Circuit Board. Qee lub hubs tuaj nrog rov qab rov qab thiab cov khoom siv fais fab. Lub caij no, qee qhov modules tso cai rau cov neeg siv los hloov cov modules tsis tau kaw tag nrho lub hub. Lub hauv paus phaj ntawm lub hub muab ntau lub tsheb npav rau cov txheej txheem ntxig, uas tuaj yeem hloov mus rau ntau ntu xws li Ethernet, Fast Ethernet, Fiber Distributed Data Interface (FDDl), thiab Asynchronous Transfer Mode (ATM). Qee lub hubs kuj suav nrog txuas txuas, routers, lossis hloov modules. Lub active chassis hub kuj yuav muaj ib tug retimeing module los koom nrog amplified cov ntaub ntawv qhia.
