Yuav ua li cas yog ib tug network card

Network card rau ib ntev lub sij hawm yog tseem ceeb tib feem ntawm cov niaj hnub lub computer, zoo li ib tug nas los yog ib lub suab card. Whereas yav tas los tsuas ib tug muaj hmoo ob peb yuav them taus los yuav cov accessories, tab sis tam sim no tsis tham txog tag nrho cov computationally multimedia system yog tsis tsim nyog.

Ua ntej peb yuav saib dab tsi hauv lub network card, cia peb ua ib tug me ntsis kev puas hlwb lus rau lub nyob deb 90. Ib qho ntawm feem nrov txoj kev uas ntawm cov ntaub ntawv pauv tau lub diskettes ntawm computers (Internet tariffs twb siab, thiab Dial-Up modem kev cob cog rua rau ib tug COM-chaw nres nkoj, ua hauj lwm thaum uas tsis muaj speeds). Txawm li cas los, ua qhov loj ntawm portable cov ntaub ntawv yuav tsum tau tsis muaj ib tug tab sis ob peb diskettes. Yog hais tias peb nco qab cov tsos ntawm lawv raug nyeem cov nplais, nws yuav tseeb hais tias cov txheej txheem yuav tsum tau mus tau zoo tuaj. Nws yog tseeb hais tias peb xav tau ib tug mechanism uas tso cai rau koj mus rau tsuas thiab sai sai txuas computers, thiab nws twb tau pom. Nco ntsoov tias cov tshuaj tau ntev tau paub, tab sis tsis yog ib tug loj.

Los ntawm motherboard xob ib tug tshwj xeeb ntaus ntawv - ib tug network card uas yog enabled los ntawm cov cable mus rau cov hloov tej cov ntaub ntawv mus rau lwm lub computer nruab nrog ib tug zoo xws li cov ntaus ntawv. baud nqi ntau lub sij hawm ntau tshaj li qhov ceev tshaj Dial-Up Modem. Lawv ua hauj lwm network card uas yuav tsum tau nyob rau hauv ib tug coaxial cable - nws yog 50 ohm "nyias" thiab cov Ethernet "tuab". Tej yam yooj yim TV tsis tuaj vim hais tias ntawm lub high school yoj kuj. Network card muaj ib tug heev "moody" ntaus ntawv - zoo hu, zoo cable, txuam stub Terminator - txhua yam yuav tsum yoog mus rau lub specification.

Tam sim no ntau tau hloov: ib tug coaxial cable twb hloov los ntawm cov khub cable, plug abolished, tej yam kuj yog txo, uas tso cai rau koj rov qab breakages yooj yim twist. Tiag hloov kis tau tus mob raws tu qauv - tswvcuab tag nrho duplex (simultaneous kis tau tus mob / txais tos nyob rau hauv ntau yam network phaib), thiab kev kub ceev tau ua ib yam. Tam sim no, ntau cov chaw muab kev muaj kev nkag tau mus rau hauv Internet yog los ntawm xws li ib tug kev txiav txim siab, thiab tsis yog ib tug modem. Los ntawm txoj kev, cov tsos ntawm cov connector cable yuav txiav txim nws hom: puag ncig - nws yog ib qhov coaxial thiab lub (yuav luag zoo li ib tug xov tooj) - ib tug twisted khub.

Yog li ntawd ib tug network card - ib tug ntaus ntawv uas muab cov ntaub ntawv hloov lwm lub tsev ntawm computers ntawm ib nrab nruab nrab (cable, xov tooj cua tsis). Thaum khw muag khoom noj tseem yuav pom nyob rau hauv daim ntawv qhia raws li ib tug nyias muaj nyias ib cov khoom siv, tag nrho cov tam sim no motherboards twb muaj soldered nti uas ua rau tag nrho cov yooj yim zog uas tau txais thiab kis lub teeb liab.

Tej network interface card muaj ib tug "stitched" xov tooj, qhov thiaj li hu ua MAC-chaw nyob uas koj muaj peev xwm txheeb xyuas nws. Yog hais tias tsim nyog, nws yuav tsum tau hloov los ntawm software.

Nyob ntawm seb cov log tsheb, paub qhov txawv PCI thiab PCI-Express card. Nyob rau hauv tej rooj plaub, indispensable lwm NIC txuas mus rau lub USB chaw nres nkoj.

Thaum uas tag nrho tam sim no cov qauv ntawm cov speeds cia ntaub ntawv hloov lwm lub tsev nyob rau hauv lub 1 Gbps, thaum ib tug thov ntawm 100 Mbit / s, txij thaum nyob rau rooj plaub no tus cable neeg pab leg ntaubntawv hauv qab no.

Yuavtsum tau kawm uantej ntawm lub network interface yog ntsia tau rau hauv tus neeg tsav tsheb system. Nws yuav tsum tau downloaded ntawm tus tsim tawm lub website thiab nruab. Tus ntaus ntawv "saib" koj lub computer thiab koj yuav sib tham nrog nws.
