1. Amanqanaba ahlukeneyo okusebenza: I-Layer 2 itshintshile isebenza kwi-data link layer, kwaye i-Layer 3 itshintshile isebenza kwi-network layer. Ukutshintsha kwe-Layer 3 akuphumeleli kuphela ukuhanjiswa kwepakethi yedatha ngesantya esiphezulu, kodwa kwakhona kufezekiseke ukusebenza kakuhle kwenethiwekhi ngokokwahluka...

Ii-transceivers zelizwe lethu zomnxeba ziphuhliswe ngokukhawuleza ngophuhliso lweshishini lokubeka iliso. Ukusuka kwi-analog ukuya kwidijithali, kwaye emva koko ukusuka kwidijithali ukuya kwi-high-definition, bahlala beqhubela phambili. Emva kweminyaka yokuqokelelwa kobugcisa, baye...

Ngophuhliso lweshishini lonxibelelwano kunye nolwazi loqoqosho lwesizwe, imarike yokutshintsha uthungelwano lweringi elawulwayo ikhule ngokuthe ngcembe. Iyabiza, ibhetyebhetye kakhulu, ilula kwaye kulula ukuyiphumeza. Itekhnoloji ye-Ethernet ...

Umsebenzi we-fiber optic transceivers kukuguqula phakathi kweempawu ze-optical kunye neempawu zombane. Isignali ye-optical igalelo kwi-port optical, kwaye isibonakaliso sombane siphuma kwi-port yombane, kwaye ngokufanayo. Inkqubo imalunga ne...

Yintoni i-IEEE 802.3? I-IEEE 802.3 liqela elisebenzayo elabhala i-Institute of Electrical and Electronics Engineers (IEEE) isethi esemgangathweni, echaza ulawulo lokufikelela okuphakathi (MAC) kuzo zombini iileyibhile zekhonkco kunye nedatha ye-Ethernet enentambo. Oku kudla ngokuba yi...

I-Optical fiber transceiver sisixhobo esingabizi kakhulu kwaye sibhetyebhetye. Ukusetyenziswa okuqhelekileyo kukuguqula imiqondiso yombane kwizibini ezijijekileyo zibe yimiqondiso ye-optical. Isetyenziswa ngokubanzi kwiintambo zobhedu ze-Ethernet ezingenako ukugqunywa kwaye kufuneka zisebenzise iifiber optical ...

Yintoni iRing network redundancy? Inethiwekhi yeringi isebenzisa iringi eqhubekayo ukudibanisa isixhobo ngasinye. Iqinisekisa ukuba isignali ethunyelwe sisixhobo esinye inokubonwa zizo zonke ezinye izixhobo kwiringi. Ukungafuneki kwenethiwekhi yeringi kubhekiselele ekubeni inkxaso yokutshintsha...

Yintoni iNethiwekhi yeTopology yeNethiwekhi yetopology ibhekisa kuyilo lwembonakalo yeempawu ezinjengokuqhagamshelwano lwendalo lwemidiya eyahlukeneyo yothumelo, iintambo zothungelwano, kwaye ixoxa ngokuthe ngqo ngonxibelelwano lweendawo ezahlukeneyo zokuphela kwenkqubo yenethiwekhi ngokuboleka ...

Yintoni i-STP? I-STP (i-Spanning Tree Protocol) yinkqubo yonxibelelwano esebenza kwinqanaba lesibini (idatha yekhonkco yedatha) kwimodeli yenethiwekhi ye-OSI. Ukusetyenziswa kwayo okusisiseko kukuthintela iilophu ezibangelwa zikhonkco ezingafunekiyo ekutshintsheni. Isetyenziselwa ukuqinisekisa ukuba kukho...

Yintoni isaqhwithi sosasazo? Isiqhwithi sosasazo sithetha nje ukuba xa idatha yosasazo ikhukhula inethiwekhi kwaye ayikwazi ukuqhutyelwa phambili, ithatha inani elikhulu le-bandwidth yenethiwekhi, okubangelwa ukungakwazi kweenkonzo eziqhelekileyo ukuqhuba, okanye ukukhubazeka okupheleleyo ...
