Dab tsi yog lub luag haujlwm tseem ceeb ntawm lub cuab yeej network adapter

Lub luag haujlwm tseem ceeb ntawm lub cuab yeej network adapter (feem ntau tseem hu ua network interface card lossis NIC) yog tsim kom muaj kev sib txuas ntawm lub cev ntawm lub khoos phis tawj thiab lub network, tso cai rau lub khoos phis tawj nkag mus rau cov peev txheej network, xa thiab txais cov ntaub ntawv. Lub luag haujlwm tseem ceeb ntawm cov cuab yeej network adapters yog raws li hauv qab no:
Kev xa cov ntaub ntawv:
Cov cuab yeej network adapter yog tus choj ntawm cov khoos phis tawj thiab tes hauj lwm, lub luag haujlwm hloov cov ntaub ntawv sab hauv mus rau hauv hom uas tuaj yeem xa mus rau hauv lub network (xws li TCP / IP raws tu qauv), thiab tom qab ntawd xa cov ntaub ntawv mus rau lub network. Nyob rau tib lub sijhawm, nws kuj tau txais cov ntaub ntawv xa los ntawm lwm yam khoom siv hauv lub network thiab hloov nws mus rau hauv hom ntawv uas lub khoos phis tawj tuaj yeem paub.
Network kev sib txuas lus:
Los ntawm cov khoom siv network adapters, khoos phis tawj tuaj yeem sib txuas lus nrog lwm lub khoos phis tawj lossis khoom siv. Txawm hais tias nyob hauv ib cheeb tsam hauv cheeb tsam network (LAN) lossis thaj chaw dav dav (WAN), daim npav network yog qhov tseem ceeb uas ua kom lub computer tuaj yeem pauv cov ntaub ntawv nrog lwm cov khoom siv.
Network nkag:
Cov cuab yeej network adapter muab lub cev sib txuas rau cov khoos phis tawj kom nkag mus rau lub network, xws li Ethernet interfaces (RJ-45) interfaces, fiber ntau optic interfaces, thiab lwm yam. Cov interfaces no tso cai rau cov khoos phis tawj txuas mus rau lub network los ntawm kev xaim lossis wireless.
Media conversion:
Qee zaum, cov khoom siv network adapters kuj yog lub luag haujlwm rau hloov cov ntaub ntawv ntawm ib lub network nruab nrab rau cov ntaub ntawv ntawm lwm qhov nruab nrab, xws li hloov los ntawm fiber ntau optic rau twisted khub.
Chaw nyob paub:
Txhua lub cuab yeej network adapter muaj qhov tshwj xeeb MAC chaw nyob (qhov chaw nkag mus siv xov xwm), uas yog siv los txheeb xyuas cov cuab yeej hauv network tshwj xeeb. Thaum cov pob ntawv cov ntaub ntawv raug xa mus rau hauv lub network, cov khoom siv xws li routers thiab keyboards yuav txiav txim siab seb lub cuab yeej twg yuav xa cov ntaub ntawv mus rau raws li MAC chaw nyob ntawm pob ntawv.
Flow Control:
Qee cov cuab yeej siv qib siab network adapters kuj muaj cov dej ntws tswj kev ua haujlwm, uas tuaj yeem pab kho qhov kev sib kis ceev ntawm cov ntaub ntawv kom tsis txhob muaj kev sib tsoo network.
Kev tswj chaw taws teeb:
Qee daim npav network kuj txhawb kev tswj hwm chaw taws teeb, xws li Wake ntawm LAN, tso cai rau cov neeg siv los pib lawv lub khoos phis tawj hauv lub network.
Hauv cov ntsiab lus, cov khoom siv network adapter yog ib qho tseem ceeb rau kev sib txuas lus ntawm cov khoos phis tawj thiab tes hauj lwm, ua kom cov khoos phis tawj nkag mus rau cov peev txheej network, ua cov ntaub ntawv xa mus, thiab sib txuas lus.
