NguMlawuli / 21 Oct 22 /0Amagqabantshintshi 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...

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, ...
