      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...
