Ethernetchinjaimhando yechinjaiyo inotumira data yakavakirwa paEthernet, uye Ethernet inzira yekugovana midhiya yekufambisa kwebhazi. Chimiro cheEthernetchinja: chiteshi chega chega cheEthernetchinjayakabatana zvakananga kumugadziri, uye kazhinji mune yakazara-duplex modhi. Thechinjainogona zvakare kubatanidza akawanda mapeya ezviteshi panguva imwe chete, kuitira kuti imwe neimwe yemauto ari kutaurirana anogona kutumira data pasina kupokana. Ethernetchinjandiyo zvakare inonyanya kufarirwa application, uye mutengo wacho wakachipa. Naizvozvo, iyo ndima yekushandisa yakakura kwazvo, uye Ethernet switch inogona kuoneka muhombe uye diki maLAN. Ethernet switch kazhinji ine akati wandei kusvika gumi nemaviri emadoko. Muchidimbu, ibhiriji retiweki rakawanda. Mukuwedzera, chiyero chayo chechiteshi chinogona kunge chakasiyana, uye maitiro ayo ekushanda anogonawo kunge akasiyana, sekupa 10M uye 100M bandwidth, kupa hafu-duplex, yakazara-duplex, uye inogadzirisa kushanda modes. Nheyo yeEthernetchinja: Ethernetchinjamuchina uri pa data link layer. Ethernet inoshandisa kero yenzvimbo (MAC kero), 48 bits, uye 6 bytes. Nheyo yayo yekushanda ndeyekuti kana nhepfenyuro yakagamuchirwa, inoendesa kune ese madoko kunze kwekugamuchira chiteshi. Kana iyo unicast furemu yagamuchirwa, tarisa kero yekwainoenda uye inoenderana netafura yekero yeMAC. Kana paine kero yekuenda, inotumirwa. Kana isipo, ichange yakazara nemvura (kutepfenyurwa). Mushure mekutepfenyura, kana pasina muenzi ane kero yeMAC yakafanana neyekwainoenda MAC kero yefuremu, inoraswa. Kana paine muenzi ane kero yeMAC yakafanana, inongowedzerwa patafura yekero yeMAC.
