Dab tsi yog ob qhov sib txawv loj ntawm modem thiab Ethernet NIC ? A modem siv cov ntaub ntawv binary thiab hloov nws mus rau cov nthwv dej analog thiab rov qab dua; Ethernet NICs hloov cov ntaub ntawv digital mus rau digital signals.
Kuj paub, qhov txawv ntawm NIC thiab modem yog dab tsi?
A NIC , los yog network card interface , tso cai rau koj lub khoos phis tawj txuas mus rau lub network uas txhua lub tshuab siv lub cev sib txuas ua ke. A modem , los yog modulater/demodulator, ua hauj lwm ntau ntawm tib lub luag haujlwm xws li a NIC tshwj tsis yog tias nws hloov digital comptuer signals rau analog signals rau kev hloov hauv xov tooj.
Qhov thib ob, yog Ethernet daim npav thiab NIC tib yam? a NIC ( network interface card ) yog ib qho daim npav uas txuas koj lub computer rau a network . Yog li ib ethernet daim npav yog ib qho piv txwv ntawm a NIC , tab sis lub modem tuaj yeem suav tias yog a NIC zoo li fiber ntau optic NIC.
Ib yam li ntawd, koj tuaj yeem txheeb xyuas lub tuam txhab daim npav network los ntawm nws qhov chaw nyob MAC li cas?
koj Txheeb xyuas lub network Card Chaw tsim khoom los ntawm saib thawj rau tus lej ntawm MAC chaw nyob.
Puas muaj lub router muaj NIC?
Lub hom phiaj-ua routers ua tsis yog muaj NICs, them muaj lub cev ports/interfaces, uas yuav siv tau rau ntau yam kev siv, thiab sab hauv (logical/virtual) interfaces uas yuav tsum tau txhais nyob rau hauv software. Servers thiab VMs txawm li cas los xij muaj NICs, lawv yog dab tsi txuas server / VM mus rau qhov hloov / router.
