Imodi yokuxhumana isho imodi yokusebenza noma imodi yokudlulisa isignali phakathi kwezinhlangothi ezimbili zokuxhumana.
1. Ukuxhumana kwe-Simplex, i-half-duplex, kanye ne-full-duplex
Ukuze uthole ukuxhumana kwephuzu kuya kwephuzu, ngokuya ngesiqondiso kanye nesikhathi sokudluliswa komlayezo, imodi yokuxhumana ingahlukaniswa ngokuxhumana okulula, okuyi-half-duplex kanye ne-full-duplex.
(1) Ukuxhumana kwe-Simplex kusho ukuthi imilayezo ingadluliselwa ohlangothini olulodwa kuphela, njengoba kuboniswe kuMfanekiso 1-6(a).
Inye kuphela yezinhlangothi ezimbili zokuxhumana engathumela, kanti enye ingathola kuphela, njengokusakaza, i-telemetry, isilawuli kude, i-wireless paging, njll. (2) Kumodi yokuxhumana ye-Half-duplex, zombili izinhlangothi zingathumela futhi zamukele imilayezo, kodwa ayikwazi ukuthumela nokwamukela imiyalezo ngesikhathi esifanayo, njengoba kukhonjisiwe kuMfanekiso 1-6(b). Isibonelo, ukusetshenziswa kwemvamisa yenethiwekhi efanayo yama-walkie-talkies ajwayelekile, imibuzo nosesho.
(3) Ukuxhumana kwe-full-duplex kubhekisela kumodi yokusebenza lapho bobabili abathintekayo bangathumela futhi bamukele imilayezo ngesikhathi esisodwa. Ngokuvamile, isiteshi sokuxhumana esiyiduplex egcwele kufanele sibe isiteshi esiqondisa kabili, njengoba kukhonjisiwe kuMfanekiso 1-6(c). Ucingo luyisibonelo esivamile sokuxhumana okugcwele okuyizimbaxambili, lapho zombili izinhlangothi zingakhuluma futhi zilalele ngesikhathi esisodwa. Ukuxhumana kwedatha okunesivinini esikhulu phakathi kwamakhompyutha kuyindlela efanayo.
2. Ukudluliselwa okuhambisanayo kanye nokudluliswa kwe-serial
Ekuxhumaneni kwedatha (ikakhulukazi ukuxhumana phakathi kwamakhompuyutha noma ezinye izisetshenziswa zetheminali yedijithali), ngokuya ngezindlela ezihlukene zokudlulisela zezimpawu zedatha, ingahlukaniswa ngokudluliswa okuhambisanayo kanye nokudluliswa kwe-serial.
(1) Ukudlulisa okuhambisanayo kuwukudlulisa ngesikhathi esisodwa ukulandelana kwezakhi zekhodi yedijithali emele ulwazi ngendlela yeqembu eziteshini ezimbili noma ngaphezulu ezihambisanayo. Isibonelo, ukulandelana kanambambili kuka-"0" kanye "no-1" okuthunyelwa ngekhompuyutha kungadluliswa kanyekanye eziteshini ezi-n parallel ngendlela yezimpawu ezingu-n eqenjini ngalinye. Ngale ndlela, izimpawu ze-n ephaketheni zingadluliswa zisuka kwesinye idivayisi ziye kwenye ngebhithi yewashi. Isibonelo, izinhlamvu ezingu-8-bit zingadluliswa ngokufana phezu kwamashaneli angu-8, njengoba kukhonjisiwe kuMfanekiso 1-7.
Inzuzo yokudlulisela okufanayo ukugcina isikhathi sokudlulisela kanye nesivinini. Ububi ukuthi imigqa yokuxhumana n iyadingeka futhi izindleko ziphezulu, ngakho-ke ngokuvamile isetshenziselwa ukuxhumana kwebanga elifushane phakathi kwamadivayisi, njengokudluliswa kwedatha phakathi kwamakhompyutha namaphrinta.
(2) Ukudluliselwa kochungechunge kubhekisela ekudluliselweni kokulandelana kwezimpawu zedijithali eshaneli ngendlela elandelanayo, uphawu ngemva kolunye, njengoba kuboniswe kuMfanekiso 1-8. Lokhu kuvame ukusetshenziselwa ukudluliswa kwedijithali okude.
Okungenhla kuyisihloko esithi "imodi yokuxhumana" olethwe kuwe ngabakwa-Shenzhen HDV Phoelectron Technology LTD., futhi i-HDV yinkampani egxile ekuxhumaneni optical njengemishini yokukhiqiza eyinhloko, ukukhiqizwa kwenkampani uqobo :Uchungechunge lwe-ONU, uchungechunge lwamamojula optical,Uchungechunge lwe-OLT, uchungechunge lwe-transceiver luwuchungechunge olushisayo lwemikhiqizo.
