Ethernet hloov yog ib hom kev hloov pauv uas xa cov ntaub ntawv raws li Ethernet, thiab Ethernet yog ib txoj hauv kev sib faib cov xov xwm tsheb npav.Tus qauv ntawm Ethernet hloov: txhua qhov chaw nres nkoj ntawm Ethernet hloov tau ncaj qha mus rau tus tswv tsev, thiab feem ntau nyob rau hauv tag nrho-duplex hom.Cov kev hloov pauv tuaj yeem txuas tau ntau yam ntawm cov chaw nres nkoj tib lub sijhawm, kom txhua tus khub ntawm cov tswv sib txuas lus tuaj yeem xa cov ntaub ntawv tsis muaj teeb meem.Ethernet hloov kuj yog daim ntawv thov nrov tshaj plaws, thiab tus nqi kuj pheej yig.Yog li ntawd, daim ntawv thov teb yog dav heev, thiab Ethernet keyboards tuaj yeem pom hauv LANs loj thiab me.Ethernet keyboards feem ntau muaj ob peb mus rau kaum ob lub chaw nres nkoj.Nyob rau hauv qhov tseeb, nws yog ib tug multi-port network choj.Tsis tas li ntawd, nws qhov chaw nres nkoj tus nqi tuaj yeem sib txawv, thiab nws txoj haujlwm ua haujlwm kuj tseem tuaj yeem sib txawv, xws li muab 10M thiab 100M bandwidth, muab ib nrab-duplex, puv-duplex, thiab hloov ua haujlwm hom.Lub hauv paus ntsiab lus ntawm Ethernet hloov: Ethernet hloov yog lub tshuab ntawm cov ntaub ntawv txuas txheej.Ethernet siv qhov chaw nyob (MAC chaw nyob), 48 khoom, thiab 6 bytes.Nws txoj hauv kev ua haujlwm yog tias thaum tau txais xov xwm tshaj tawm, nws yuav xa mus rau txhua qhov chaw nres nkoj tshwj tsis yog qhov chaw txais txais.Thaum tau txais unicast thav duab, xyuas nws qhov chaw nyob thiab coj mus rau nws qhov chaw nyob MAC.Yog tias muaj qhov chaw nyob, nws yuav raug xa mus.Yog tias tsis muaj, nws yuav raug dej nyab (tshaj tawm).Tom qab tshaj tawm, yog tias tsis muaj tus tswv tsev uas nws qhov chaw nyob MAC yog tib yam li qhov chaw nyob MAC ntawm tus ncej, nws yuav raug muab pov tseg.Yog tias muaj ib tus tswv tsev uas nws qhov chaw nyob MAC yog tib yam, nws yuav raug muab ntxiv rau nws qhov chaw nyob MAC.
