Imo yonxibelelwano ibhekisa kwimowudi yokusebenza okanye imowudi yokuhanjiswa komqondiso phakathi kwamaqela amabini onxibelelwano.
1. I-Simplex, i-half-duplex, kunye ne-full-duplex yonxibelelwano
Ukunxibelelana kwinqanaba ukuya kwinqanaba, ngokwesikhokelo kunye nexesha lokuhanjiswa komyalezo, indlela yokunxibelelana inokwahlulwa ibe yi-simplex, i-half-duplex kunye ne-full-duplex yonxibelelwano.
(1) Unxibelelwano olulula luthetha ukuba imiyalezo ingathunyelwa kwicala elinye kuphela, njengoko kuboniswe kuMzobo 1-6 (a).
Inye kuphela yamaqela amabini onxibelelwano angathumela, kwaye enye inokufumana kuphela, njengokusasaza, i-telemetry, i-remote control, i-wireless paging, njl. kodwa ayikwazi ukuthumela nokufumana imiyalezo ngexesha elinye, njengoko kubonisiwe kuMfanekiso 1-6(b). Ngokomzekelo, ukusetyenziswa kwe-carrier carrier frequency yesiqhelo se-walkie-talkies, imibuzo kunye nokukhangela.
(3) Unxibelelwano olupheleleyo lwe-duplex lubhekisela kwindlela yokusebenza apho omabini amaqela angathumela kwaye afumane imiyalezo ngexesha elinye. Ngokuqhelekileyo, umjelo ogcweleyo wonxibelelwano kufuneka ube ngumjelo we-bidirectional, njengoko kubonisiwe kuMfanekiso 1-6(c). Umnxeba ngumzekelo oqhelekileyo wonxibelelwano olupheleleyo lwe-duplex, apho omabini amaqela anokuthetha kwaye aphulaphule ngaxeshanye. Unxibelelwano lwedatha olukhawulezayo phakathi kweekhompyuter lukwayindlela enye.
2. Ukuhanjiswa kwe-Parallel kunye ne-serial transmission
Kunxibelelwano lwedatha (ingakumbi unxibelelwano phakathi kweekhompyuter okanye ezinye izixhobo ze-terminal yedijithali), ngokweendlela ezahlukeneyo zothumelo lweempawu zedatha, inokwahlulwa ibe yi-parallel transmission kunye ne-serial transmission.
(1) Ukuhanjiswa okufanayo kukuhanjiswa ngaxeshanye kokulandelelana kwezinto zekhowudi yedijithali emele ulwazi ngendlela yeqela kwiitshaneli ezimbini okanye ngaphezulu ezihambelanayo. Umzekelo, ulandelelwano lokubini luka-"0" kunye no-"1" oluthunyelwe yikhompyutha lunokuhanjiswa ngaxeshanye kutshaneli u-n parallel ngendlela yeesimboli n kwiqela ngalinye. Ngale ndlela, iisimboli ze-n kwipakethi zinokugqithiselwa ukusuka kwesinye isixhobo ukuya kwesinye ngaphakathi kwesingqi sewotshi. Ngokomzekelo, iimpawu ze-8-bit ziyakwazi ukuhanjiswa ngokuhambelana kwiitshaneli ezi-8, njengoko kubonisiwe kuMfanekiso 1-7.
Inzuzo yothumelo oluhambelanayo kukugcina ixesha losulelo kunye nesantya. Ukungalungi kukuba iintambo zonxibelelwano n ziyafuneka kwaye iindleko ziphezulu, ngoko ke isetyenziselwa kuphela unxibelelwano olufutshane phakathi kwezixhobo, ezifana nokuhanjiswa kwedatha phakathi kweekhompyuter kunye nabashicileli.
(2) Ukuhanjiswa kothotho kubhekiselele ekugqithisweni kolandelelwano lweempawu zedijithali kwitshaneli ngendlela elandelelanayo, isimboli esinye emva kwenye, njengoko kubonisiwe kuMfanekiso 1-8. Oku kudla ngokusetyenziselwa ukuhanjiswa kwedijithali kumgama omde.
Eli nqaku lingasentla linqaku elithi "imo yonxibelelwano" eliziswe kuwe yi-Shenzhen HDV Phoelectron Technology LTD., Kwaye i-HDV yinkampani ekhethekileyo kunxibelelwano lwe-optical njengesona sixhobo sokuvelisa, imveliso yenkampani: Uchungechunge lwe-ONU, uchungechunge lwemodyuli ye-optical,OLT series, Uchungechunge lwe-transceiver luluhlu olushushu lweemveliso.
