      Iinkcukacha eziBanzi malunga nonxibelelwano lweDatha kunye nothungelwano lweKhompyutha

      Ukuqonda unxibelelwano lwedatha kwinethiwekhi kunzima. Kweli nqaku ndiza kubonisa ngokulula ukuba iikhompyuter ezimbini zidibana njani, zigqithise kwaye zifumane ulwazi lwedatha kunye ne-Tcp/IP yeprotocol yomaleko amahlanu. Yintoni unxibelelwano lweDatha? Igama elithi "unxibelelwano lwedatha" i...

      Umahluko phakathi kokutshintsha kwe-Managed Vs engalawulwayo kwaye uthenge eyiphi?

      Iiswitshi ezilawulwayo ziphezulu kunezo zingalawulwayo ngokwemigaqo yokusebenza, kodwa zifuna ubuchule bomlawuli okanye injineli ukuze baqonde ngokupheleleyo amandla abo. Ulawulo oluchanekileyo ngakumbi lothungelwano kunye nezakhelo zabo zedatha zenziwe ukuba zikwazi ukusebenzisa iswitshi elawulwayo. Kwelinye icala, ...

      Yintoni iliza lokuKhanya kwiinkcukacha [Kucacisiwe]

      Amaza okukhanya yimitha ye-electromagnetic eveliswa zii-electron kwinkqubo yentshukumo yeathom. Ukushukuma kwee-electron kwiiathom zezinto ezahlukeneyo kwahlukile, ngoko ke amaza okukhanya eziwakhuphayo nawo ahlukile. I-Spectrum yipateni yokukhanya kwe-monochromatic eyahlulwe yinkqubo yokusasazwa (...

      Izinto eziluncedo kunye neMigangatho ye-Ethernet

      Inkcazo yengqiqo: I-Ethernet ngowona mgangatho wonxibelelwano uqhelekileyo owamkelwa yiLAN ekhoyo. Inethiwekhi ye-Ethernet isebenzisa i-CSMA / CD (i-Carrier Sense Access Multiple Access kunye ne-Conflict Detection) ubuchwepheshe. I-Ethernet ilawula iteknoloji ye-LAN: 1. Ixabiso eliphantsi (ngaphantsi kwe-100 yenethiwekhi ye-Ethernet imoto...

      Indlela yokulawula ukufikelela okuphakathi kwe-LAN

      Indlela yokufikelela kunye nokulawula izixhobo ezahlukeneyo zekhompyuter ngokusebenzisa imidiya kwi-LAN iqondwa ngolu hlobo lulandelayo. Kwakudala, i-Ethernet yayisetyenziselwa ukudibanisa yonke imigca yeekhompyuter zekhaya kwibhasi ukuqonda unxibelelwano oludibeneyo lweekhompyuter. Xa usebenzisa le ndlela yokuthumela idatha, kufuneka...
