Njira yolankhulirana ndiyo njira imene anthu awiriwa amachitira zinthu limodzi kapena kutumiza mauthenga.
1. Kuyankhulana kwa Simplex, theka-duplex ndi full-duplex
Pakulankhulana molunjika, molingana ndi malangizo ndi nthawi yotumizira uthenga, njira yolumikizirana imatha kugawidwa mu simplex, half-duplex, and full-duplex communication.
(1) Kuyankhulana kwa Simplex kumatanthawuza njira yogwirira ntchito yomwe mauthenga amatha kutumizidwa kumbali imodzi, monga momwe tawonetsera pa Chithunzi 1-6 (a).
Chifukwa chake chimodzi mwamagawo awiri olankhulirana chimangotumiza ndipo china chimangolandira, monga kuwulutsa, telemetry, kuwongolera kwakutali, paging opanda zingwe, ndi zina zotero. (2) Kuyankhulana kwa theka-duplex kumatanthawuza njira yogwirira ntchito yomwe mbali zonse ziwiri zoyankhulirana zimatha kutumiza ndi kulandira mauthenga, koma osati nthawi yomweyo, monga momwe tawonetsera pa Chithunzi 1-6 (b). Mwachitsanzo, ma walkie-talkies wamba amagwiritsa ntchito mafupipafupi onyamulira, kufunsa ndi kubweza, ndi zina.
(3) Kuyankhulana kwamtundu uliwonse (Duplex) kumatanthawuza njira yogwiritsira ntchito yomwe onse awiri amatha kutumiza ndi kulandira mauthenga nthawi imodzi. Nthawi zambiri, njira yolankhulirana mowirikiza kawiri iyenera kukhala njira yapawiri, monga momwe zasonyezedwera pa Chithunzi 1-6(c). Foni ndi chitsanzo chodziwika bwino cha kulumikizana kowirikiza kawiri, komwe onse awiri oyimba amatha kulankhula ndikumvetsera nthawi imodzi. N'chimodzimodzinso ndi kulankhulana kwachangu kwa data pakati pa makompyuta.
Kutumiza kwa 2.Parallel ndi kutumiza kwachinsinsi
Kuyankhulana kwa data (makamaka kulumikizana pakati pa makompyuta kapena zida zina za digito), malinga ndi njira zosiyanasiyana zotumizira zizindikiro za data. Iwo akhoza kugawidwa mu kufanana kufala ndi siriyo kufala.
(1) Kupatsirana kofanana ndiko kusanjika kwa ma tchanelo awiri kapena kupitilira apo omwe amatumiza zizindikiro za digito zomwe zimayimira chidziwitso nthawi imodzi. Mwachitsanzo, chizindikiro cha binary chomwe chimakhala ndi "0" ndi "1" chotumizidwa ndi kompyuta chingathe kufalitsidwa nthawi imodzi pa n tchanelo chofananira monga zizindikiro za n pa gulu. Mwanjira imeneyi, zizindikiro za n mu paketi zitha kusamutsidwa kuchokera ku chipangizo chimodzi kupita ku china mkati mwa wotchi imodzi. Mwachitsanzo, zilembo za 8-bit zitha kufalitsidwa mofananira pogwiritsa ntchito ma tchanelo 8, monga momwe tawonetsera pa Chithunzi 1-7.
Ubwino wa kupatsirana kofanana ndikuti umapulumutsa nthawi yopatsirana komanso mwachangu. Choyipa ndichakuti n mizere yolumikizirana ndiyofunikira ndipo mtengo wake ndi wokwera, motero umangogwiritsidwa ntchito polumikizana kwakanthawi kochepa pakati pa zida, monga kutumiza deta pakati pa kompyuta ndi chosindikizira.
(2) Kutumiza kwa seri ndikutumiza zizindikiro za digito panjira motsatizana, chizindikiro ndi chizindikiro, monga momwe tawonetsera pa Chithunzi 1-8. Njirayi imagwiritsidwa ntchito nthawi zambiri kufalitsa digito.
Zomwe zili pamwambazi ndi nkhani yakuti "Data transmission mode of communication mode" yobweretsedwa kwa inu ndi Shenzhen HDV phoelectron Technology Co., Ltd. ndikuyembekeza kuti nkhaniyi ingakuthandizeni kuonjezera chidziwitso chanu. Kupatula nkhaniyi ngati mukuyang'ana kampani yabwino yopanga zida zoyankhulirana zama fiber zomwe mungaganizirezambiri zaife.
Shenzhen HDV phoelectron Technology Co., Ltd. ndiyomwe imapanga zinthu zolumikizirana. Pakadali pano, zida zomwe zimapangidwa zimakwiriraZithunzi za ONU, Optical module mndandanda, Zithunzi za OLT,nditransceiver mndandanda. Titha kupereka ntchito makonda pazochitika zosiyanasiyana. Mwalandiridwafunsani.
