Utshintsho lweswitshi ngeendlela ezintathu ezilandelayo
1) I-Straight-through: I-straight-through Ethernet switch inokuqondwa njenge-line matrix telephone switch ene-crossover phakathi kwee-ports. Xa ibona ipakethi yedatha kwi-input port, ijonga i-packet header yepakethi, ifumane idilesi yendawo ekuyiwa kuyo ipakethi, iqalise i-interna...Funda ngokugqithisileyo -
Impembelelo yokukhanya okubuthathaka kwe-ONU kwisantya senethiwekhi
I-ONU yinto esiyibiza ngokuba yi "light cat", ukukhanya okuphantsi kwe-ONU kubhekisa kwinto yokuba amandla okukhanya afunyenwe yi-ONU angaphantsi kobukhali bokwamkela be-ONU. Ubukhali bokwamkela be-ONU bubhekisa kubukhali bokukhanya obuncinci obunokufumaneka yi-ONU ngexesha eliqhelekileyo...Funda ngokugqithisileyo -
Yintoni iswitshi? Yenzelwe ntoni?
Iswitshi (Switshi) ithetha "iswitshi" kwaye sisixhobo senethiwekhi esisetyenziselwa ukudlulisela isignali yombane (ebonakalayo). Ingabonelela ngendlela ekhethekileyo yesignali yombane kuzo naziphi na ii-node ezimbini zenethiwekhi zeswitshi yokufikelela. Ezona switshi zixhaphakileyo ziiswitshi ze-Ethernet. Ezinye eziqhelekileyo zii-vo...Funda ngokugqithisileyo -
Zingaphi ii-ONU ezinokunxibelelana ne-OLT enye?
64, ngokubanzi ingaphantsi kwe-10. 1. Ngokwethiyori, i-64 inokudityaniswa, kodwa xa kujongwa ukuncitshiswa kokukhanya kunye novakalelo lwe-onu ekukhanyeni, kwizicelo ezisebenzayo ngokubanzi, inani loqhagamshelo ngezibuko lingaphantsi kwe-10. Inani eliphezulu labasebenzisi abafikelelwa yi-olt linqunyelwe ikakhulu zii...Funda ngokugqithisileyo -
