    Njira Yolumikizirana

    Nthawi yotumiza: Nov-09-2024

    Njira yolankhulirana imatanthawuza njira yogwirira ntchito kapena njira yotumizira zizindikiro pakati pa magulu awiri olankhulana.

    1. Kuyankhulana kwa Simplex, half-duplex, ndi full-duplex

    Pakulankhulana molunjika, molingana ndi malangizo ndi nthawi yotumizira uthenga, njira yolankhulirana imatha kugawidwa mu simplex, half-duplex and full-duplex communication.

    (1) Kuyankhulana kwa Simplex kumatanthauza kuti mauthenga amatha kutumizidwa kumbali imodzi yokha, monga momwe tawonetsera pa Chithunzi 1-6 (a).
    Mmodzi yekha mwa maphwando awiri oyankhulana angatumize, ndipo winayo angalandire, monga kuwulutsa, telemetry, kulamulira kwakutali, paging opanda zingwe, etc. (2) Mu njira yolankhulirana ya Half-duplex, onse awiri akhoza kutumiza ndi kulandira mauthenga, koma sangathe kutumiza ndi kulandira mauthenga nthawi imodzi, monga momwe tawonetsera pa Chithunzi 1-6 (b). Mwachitsanzo, kugwiritsa ntchito pafupipafupi chonyamulira cha walkie-talkies wamba, kufunsa ndi kusaka.
    (3) Kuyankhulana kwathunthu kumatanthauza njira yogwirira ntchito yomwe onse awiri amatha kutumiza ndi kulandira mauthenga nthawi imodzi. Nthawi zambiri, njira yolumikizirana yokhazikika iwiri iyenera kukhala njira yolumikizirana pawiri, monga momwe zasonyezedwera pa Chithunzi 1-6(c). Foni ndi chitsanzo chodziwika bwino cha kulumikizana kwathunthu, pomwe onse awiri amatha kulankhula ndikumvetsera nthawi imodzi. Kuyankhulana kwachangu kwa data pakati pa makompyuta ndi njira yomweyo.

    2. Parallel kufala ndi siriyo kufala

    Mukulankhulana kwa data (makamaka kulumikizana pakati pa makompyuta kapena zida zina za digito), malinga ndi mitundu yosiyanasiyana yotumizira zizindikiro za data, zitha kugawidwa m'mapatsirana ofananira ndi kufalitsa kwa serial.

    (1) Kupatsirana kofananira ndiko kutumizirana munthawi yomweyo zinthu zotsatizana za digito zomwe zimayimira chidziwitso pagulu panjira ziwiri kapena zingapo zofananira. Mwachitsanzo, ndondomeko ya binary ya "0" ndi "1" yotumizidwa ndi kompyuta ikhoza kufalitsidwa nthawi imodzi pa n tchanelo chofananira mu mawonekedwe a n zizindikiro pa gulu. Mwanjira imeneyi, zizindikiro za n mu paketi zimatha kufalitsidwa kuchokera ku chipangizo chimodzi kupita ku china mkati mwa kugunda kwa wotchi. Mwachitsanzo, zilembo za 8-bit zitha kufalitsidwa motsagana pa tchanelo 8, monga momwe chithunzi 1-7 chikusonyezera.
    Ubwino wa kufala kufanana ndi kupulumutsa kufala nthawi ndi liwiro. 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 makompyuta ndi osindikiza.
    (2) Kutumiza kwa seriyo kumatanthawuza kufalitsa katsatidwe ka zizindikiro za digito panjira motsatizana, chizindikiro chimodzi pambuyo pa chinzake, monga momwe tawonetsera pa Chithunzi 1-8. Izi nthawi zambiri zimagwiritsidwa ntchito pofalitsa digito mtunda wautali.
    Pamwambapa ndi "kulumikizana mumalowedwe" nkhani anabweretsedwa kwa inu ndi Shenzhen HDV Phoelectron Technology LTD., ndipo HDV ndi kampani okhazikika mu kuwala kulankhulana monga zida waukulu kupanga, kupanga kampaniyo: ONU mndandanda, kuwala gawo mndandanda,Zithunzi za OLT, mndandanda wa transceiver ndiwotentha kwambiri wazinthu.
