I-Ethernet port - RJ45
Njengoko kubonisiwe kulo mzobo ungasentla, sinokuqonda ukubonakala kwe-RJ45 ngokomfanekiso, kodwa ayizizo zonke ii-interface ze-RJ45 ezifana nale ilapha ngasentla ziyi-interfaces ze-RJ11, ezingayi kuxoxwa okwethutyana. Iiswitshi zicwangciswe ecaleni kunye namazibuko e-RJ45 amaninzi, apho ...Funda ngokugqithisileyo

Umgaqo wokuSebenza weTshintsho
okanye imodeli yereferensi ye-OSI, umtshintshi usebenza kwinqanaba lesibini lalo mzekelo, i-data link layer. Njengoko kubonisiwe kulo mzobo ulandelayo, iswitshi inamazibuko asibhozo. Xa isixhobo siplagiwe kwisitshixo nge-RJ45, iswitshi eyintloko yetshiphu iya kuchonga izibuko eziplagwe kuthungelwano...Funda ngokugqithisileyo
