Ikhowudi yokubona imposiso kuLuhlu lweDatha loDityaniso [Icacisiwe]
Ikhowudi yokubona imposiso (ikhowudi yokujonga i-parity): ikhowudi yokukhangela i-parity iqulethe i-n-1 bit unit yolwazi kunye ne-1 bit check element. Iyunithi yolwazi ye-N-1 yidatha esebenzayo kwiinkcukacha esizithumelayo, kwaye iyunithi yokujonga i-1-bit isetyenziselwa ukukhangela impazamo kunye nekhowudi yokuphinda iphinde iphinde iphinde iphinde isetyenziswe. Ukujonga okungaqhelekanga: ukuba i-n...Funda ngokugqithisileyo - Ngu Admin / 03 Aug 22 /0Amagqabantshintshi
I-OSI-Data yoQhagamshelwano lweLayer-Error Control [Icacisiwe]
Molweni, Bafundi. Kweli nqaku ndiza kuxoxa nge-OSI-Data yoLawulo lwemposiso yoMaleko weNgcaciso ngengcaciso. Masiqale… Ukuqonda usasazo lwedatha yomaleko makhe sithathe umzekelo, ukuba isixhobo esingu-A sifuna ukunxibelelana nesixhobo esingu-B, ikhonkco lonxibelelwano ...Funda ngokugqithisileyo - Ngu Admin / 02 Aug 22 /0Amagqabantshintshi
Ulawulo lwemposiso kwiNkqubo yoNxibelelwano lweDatha
Molweni Bafundi, Kweli nqaku siza kufunda ukuba yintoni Ulawulo lwemposiso kunye nokuhlelwa kokulawula iimpazamo. Kwinkqubo yokuhanjiswa kwedatha, ngenxa yempembelelo yengxolo kwitshaneli, i-wave waveform inokuphazamiseka xa idluliselwa kumamkeli, kwakhona ...Funda ngokugqithisileyo - Ngu Admin / 01 Aug 22 /0Amagqabantshintshi
I-OSI-Datha yoQhagamshelwano loMaleko-Isakhelo sokuSebenzisa ungqamaniso
Kwinkqubo yedijithali yolwahlulo lwe-multiplexing yonxibelelwano lwexesha, ukwenzela ukwahlula ngokuchanekileyo iimpawu ze-slot yexesha, isiphelo sokuthumela kufuneka sinikeze uphawu lokuqala lwesakhelo ngasinye, kunye nenkqubo yokufumanisa kunye nokufumana olu phawu ekupheleni kokufumana kubizwa ngokuba yi-synchr . .Funda ngokugqithisileyo - Ngu Admin / 29 Jul 22 /0Amagqabantshintshi
Iimpawu zeOSI Physical Layer
Umaleko womzimba usezantsi kwimodeli ye-OSI, kwaye umsebenzi wayo ophambili kukusebenzisa i-transmission medium ukubonelela uqhagamshelo olubonakalayo lomaleko wekhonkco ledatha ukuhambisa imilambo. Umaleko womzimba uchaza indlela intambo eqhagamshelwe ngayo kwinethiwekhi c...Funda ngokugqithisileyo - Ngu Admin / 28 Jul 22 /0Amagqabantshintshi
Imodyuli yesiZibuko soMbane kunye noMahluko weModyuli yePort yokubona
Abantu abaninzi abacaci kakuhle malunga neemodyuli ze-port yombane, okanye bahlala bedidekile kunye neemodyuli ze-optical, kwaye abanako ukukhetha iimodyuli ze-port zombane ngokuchanekileyo ukuhlangabezana nenzuzo efanayo yokuhanjiswa komgama kunye nokulungiswa kweendleko. Ke, kobu bugcisa...Funda ngokugqithisileyo
