      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...

      Yintoni i-IEEE 802ax: (Wi-Fi 6) – kwaye Isebenza njani ngokukhawuleza?

      Okokuqala, makhe sifunde nge-IEEE 802.11ax. Kumfelandawonye we-WiFi, ibizwa ngokuba yi-WiFi 6, ekwabizwa ngokuba yinethiwekhi yendawo engenazingcingo engenazingcingo. Ngumgangatho wothungelwano lwengingqi olungenazingcingo. I-11ax ixhasa i-2.4GHz kunye ne-5GHz iibhendi, kwaye inokubuyela ngasemva iyahambelana neprotoco esetyenziswa ngokuqhelekileyo ...
