Indlela yokuxhumana yindlela abantu ababili abakhuluma bodwa abasebenzisana ngayo noma ukuthumela imiyalezo.
1. Ukuxhumana kwe-Simplex, i-half-duplex kanye ne-full-duplex
Ukuze uthole ukuxhumana kwephuzu nephuzu, ngokuya ngesiqondiso kanye nobudlelwano besikhathi sokudluliswa komlayezo, imodi yokuxhumana ingahlukaniswa ngokuxhumana okulula, okuyi-half-duplex, kanye ne-full-duplex.
(1) Ukuxhumana kwe-Simplex kubhekisela kumodi yokusebenza lapho imilayezo ingadluliselwa ohlangothini olulodwa kuphela, njengoba kuboniswe kuMfanekiso 1-6(a).
Ngakho-ke enye yezinhlangothi ezimbili zokuxhumana ingathumela kuphela kanti enye ingathola kuphela, njengokusakaza, i-telemetry, isilawuli kude, ukupheja okungenantambo, nokunye. (2) Ukuxhumana kwe-half-duplex kubhekisela endleleni yokusebenza lapho bobabili abathintekayo ekuxhumaneni bangathumela futhi bamukele imilayezo, kodwa hhayi ngesikhathi esifanayo, njengoba kuboniswe kuMfanekiso 1-6(b). Isibonelo, ama-walkie-talkies ajwayelekile asebenzisa imvamisa yenkampani yenethiwekhi efanayo, ukubuza nokubuyiswa, njll.
(3) Ukuxhumana kwe-Full-duplex (Duplex) kubhekisela kumodi yokusebenza lapho bobabili abathintekayo bangathumela futhi bamukele imilayezo ngesikhathi esisodwa. Ngokuvamile, umzila wokuxhumana okuphindwe kabili kufanele kube umzila oqondiswa kabili, njengoba kukhonjisiwe kuMfanekiso 1-6(c). Ucingo luyisibonelo esijwayelekile sokuxhumana okuyizimbaxambili, lapho zombili izinhlangothi ocingweni zingakhuluma futhi zilalele ngesikhathi esisodwa. Okufanayo kuyiqiniso ekuxhumaneni kwedatha ngesivinini esikhulu phakathi kwamakhompyutha.
2.Parallel transmission and serial transmission
Ukuxhumana kwedatha (ikakhulukazi ukuxhumana phakathi kwamakhompuyutha noma ezinye izisetshenziswa zetheminali yedijithali), ngokuya ngezindlela ezihlukene zokudlulisa izimpawu zedatha. Zingahlukaniswa zibe ukudluliswa okufanayo kanye nokudluliswa kwe-serial.
(1) Ukudluliselwa okuhambisanayo kuwukuhlanganisa amashaneli amabili noma ngaphezulu ahambisanayo adlulisa ukulandelana kwezimpawu zedijithali ezimelela ulwazi ngesikhathi esisodwa. Isibonelo, ukulandelana kophawu olunambambili ohlanganisa okuthi “0″ kanye “1″ okuthunyelwe ngekhompuyutha kungasakazwa ngesikhathi esisodwa kumashaneli angu-n parallel ngendlela yezimpawu ezingu-n eqenjini ngalinye. Ngale ndlela, izimpawu zika-n ephaketheni zingadluliswa zisuka kwesinye idivaysi ziye kwenye ngaphakathi kokuthiki wewashi elilodwa. Isibonelo, izinhlamvu ze-8-bit zingadluliswa ngokuhambisana kusetshenziswa amashaneli ayi-8, njengoba kukhonjisiwe kuMfanekiso 1-7.
Ubuhle bokudluliswa kwe-parallel ukuthi yonga isikhathi sokudlulisela futhi kuyashesha. Ububi ukuthi izintambo zokuxhumana n ziyadingeka futhi izindleko ziphezulu, ngakho-ke ngokuvamile zisetshenziselwa ukuxhumana kwebanga elifushane phakathi kwamadivaysi, njengokudluliswa kwedatha phakathi kwekhompyutha nephrinta.
(2) Ukudluliswa kwe-serial ukudlulisa ukulandelana kwezimpawu zedijithali esiteshini ngendlela ye-serial, uphawu ngophawu, njengoba kuboniswe kuMfanekiso 1-8. Le ndlela ivame ukusetshenziselwa ukudluliswa kwedijithali okude.
Okungenhla kuyisihloko esithi "Imodi yokudlulisa idatha yemodi yokuxhumana" olethwe kuwe yi-Shenzhen HDV phoelectron Technology Co., Ltd. ngethemba ukuthi lesi sihloko singakusiza ukukhulisa ulwazi lwakho. Ngaphandle kwalesi sihloko uma ufuna inkampani enhle yabakhiqizi bemishini yokuxhumana ye-fiber ongase uyicabangeleMayelana NATHI.
I-Shenzhen HDV phoelectron Technology Co., Ltd. ingumkhiqizi wemikhiqizo yezokuxhumana. Njengamanje, imishini ekhiqizwayo ihlanganisaUchungechunge lwe-ONU, optical module uchungechunge, Uchungechunge lwe-OLT, futhiuchungechunge lwe-transceiver. Singahlinzeka ngezinsizakalo ezenziwe ngezifiso ezimweni ezahlukahlukene. Wamukelekilebonisana.
