Kuti udzivise kukanganiswa kwemagetsi (EMI) uye kuve nechokwadi chekuenderana kwemagetsi (EMC), ndege dzekumashure dzinofanira kutevedzera zviyero zveindasitiri. Izvi zvinosanganisira:
Nzira dzekudzivirira kudzivirira kupindira kusingadiwi
Kuve nechokwadi chekuti ndege dzepasi dzakakodzera kuchengetedza chiratidzo chekuvimbika uye kudzivirira ruzha
Aya magadzirirwo ekufunga anovimbisa kuti backplanes inoita zvakaringana mumhando dzakasiyana-siyana dzepamusoro-soro masisitimu, inosimudzira kuvimbika, scalability, uye kuvimbika kwedata uchichengeta kuteedzera zviyero zveindasitiri.
7.Kusiyana kwakakosha pakati peBackplanes uye Motherboards
Nepo ese ari maviri backplanes uye mamaboards akabatana kune zvemagetsi masisitimu, iwo akasiyana mukushanda, dhizaini, uye mashandisiro. Kunzwisisa misiyano iyi kunobatsira pakusarudza chikamu chakakodzera kune yako chaiyo system inoda.
A. Kuenzanisa Kwekuita:
Mabhodhi eamai: Inonyanya kushandiswa mumakomputa emunhu uye malaptop, mabhodhi eamai anoshanda seyakanyanya redunhu bhodhi rinogara iyo CPU, ndangariro, uye yekuwedzera slots yeI / O zvishandiso. Ivo vanosanganisa simba rekugadzirisa uye yekubatanidza mubhodhi rimwechete, rakanakira compact masisitimu.
Backplanes: Kusiyana nemabhodhi eamai, backplanes inotarisa pakubatana uye modularity. Iwo haawanzo kusanganisira simba rekugadzirisa asi panzvimbo pezvo anopa slots yekuisa makadhi ekuwedzera, mabhodhi evanasikana, uye peripheral modules. Izvi zvinoita kuti backplanes ive yakakodzera kune maindasitiri, nharembozha, uye server nharaunda uko scalability uye redundancy zvinoiswa pamberi.
B. Shandisa Nyaya kune Imwe neimwe:
Mabhodhi eamai: Zvakanakisa zvemagetsi zvevatengi uye madiki komputa masisitimu uko kubatanidzwa kwese zvikamu mubhodhi rimwe kunodiwa. Mienzaniso inosanganisira makomputa edesktop, malaptop, uye masisitimu emitambo.
Backplanes: Yakanakira modular masisitimu uko kuwedzera kweramangwana kana kugadzirisa kwakakosha. Iwo anoshandiswa zvakanyanya mumasevha, networking zvishandiso, telecommunication, uye maindasitiri otomatiki.
C. Evolution kubva kuMaibhodhi kuenda kuModular Backplanes:
Sezvo masisitimu awedzera kuomarara, kudiwa kweanokatyamadza uye modular zvivakwa zvakafambisa shanduko kubva kuchinyakare mamaboards kuenda kubackplane-based system. Aya mabackplanes anobvumira kukwidziridzwa kuri nyore, magetsi asina simba, uye nekuwedzera kwemakadhi ekuwedzera ehunyanzvi akagadzirirwa kumabasa chaiwo.
Muchidimbu, nepo mabhodhi eamai achipa mhinduro-mune-imwe yezvishandiso zvidiki, ndege dzekumashure dzinopa kuchinjika kukuru, modularity, uye kuita mune zvakanyanya kuoma-kuita masisitimu.
