Dial-up modems yakaenda kune-high-speed broadband modems
Modem iyo iri hardware iyo inobvumira kombiyuta kutumira uye kugamuchira dheperi pamusoro petsamba yefoni kana mutambo kana satanisi. Muchiitiko chekutumira kune imwe nhare yefoni, iyo ndiyo yaimbova nzira yakakurumbira yekuwanika paIndaneti, modem inoshandura dhana pakati peanorog uye zvigadzirwa zvechidimbu munguva chaiyo ye-two-network network communication. Muchiitiko che-high-speed digital modems yakakurumbira nhasi, chiratidzo chacho chiri nyore uye hachidi kutendeuka kweanalog-to-digital.
Nhoroondo yeModems
Maikirwe ekutanga anonzi modems akachinjwa dhidhijiti yedhidhi yekutumira pamagetsi efoni analogog. Nhanho yemodemikari iyi yakave yakarongedzwa mumabhaud (chikwata chekuyera chinonzi Emile Baudot), kunyange zvazvo teknolojia yekombiyuta yakagadzirwa, zviyero izvi zvakachinjwa kuva bits kwechipiri . Ikutanga yekutengeserana modems yakatsigira nhanho ye 110 bps uye yakashandiswa neDhipatimendi rekudzivirirwa kweUnited States, nhepfenyuro dzemashoko, uye mamwe mabhizimusi makuru.
Modem zvishoma nezvishoma yakasvika pakuzivikanwa kune vatengi mukunonoka kwema70s kuburikidza nemakore makumi mapfumbamwe nemakumi mapfumbamwe nemasere emashoko ehurumende uye nhepfenyuro dzemashoko seCompuServe dzakavakwa pahutano hwekutanga hwetaneti. Zvadaro, nekuputika kweWorld Wide Web pakati pekupera kwema1990, kushambadzira-modem modems kwakauya senzira yekutanga yekuwanika kwepaInternet mumhuri zhinji pasi rose.
Dial-Up Modems
Mutemo wemamashoni anoshandiswa padial-up network inoshandura dhaka pakati pefomu yeanalogog inoshandiswa pamatafura efoni uye fomu yemagetsi yakashandiswa pamakombiyuta. Imwe nzira yekuvhara-modem yekunze inovhara mu kombiyuta pane imwe mugumo uye nhare yefoni pane imwe mugumo. Munguva yakapfuura, vamwe vanoita kombiyuta vanobatanidza mukati mekushandisa-up modems mumakombiyuta avo maitiro.
Mazuva ano dial-up network modems inotumira dhiyabhorosi pachiyero chikuru chema 56,000 bits pamusi wechipiri. Zvisinei, zvisizvo zvinokonzerwa nehuterevhizheni dzenhare dzinowanzopedza modem data kusvika ku 33.6 Kbps kana kuderera mukuita.
Paunotaurirana kune unhare kuburikidza ne-dial-up modem, maikirwo acho anowanzoenderera kuburikidza nemukurukuri mazwi akasiyana anoshandiswa nekutumira dhidhijiti kudarika inzwi rezwi. Nokuti nzira yekubatanidza uye nhamba yematare yakafanana nguva imwe neimwe, kunzwa mutauro wezwi kunobatsira user kuti aone kana chirongwa chekubatanidza chiri kushanda.
Broadband Modems
Modem yebandaneti yakawanda yakafanana neyo inoshandiswa kuDVDL kana kutengesa kwekombiyuta inoshandisa nzira dzekugadzirisa dzakapfuura kuti ibudirire zvakanyanya kukurumidza kushamwaridzana nemitambo kudarika tsika dzekudhinda-modems. Broadband modems inowanzonzi se-high-speed modems. Cellular modems ndiyo inonzi digital modem inotanga internet kuwirirana pakati pefoni yefoni uye foni network .
External broadband modems plug in a home broadband router kana imwe yesuo remasuo pamba pane imwe mugumo uye kunze kwemaInternet interface semukati wekambani kune imwe. Iyo router kana gedhi inotungamirira chiratidzo kune zvose zvigadzirwa mubhizinesi kana kumba kana zvichidiwa. Mamwe mabhiriji e-broadband anosanganisira modem yakabatana semumwechete hardware unit.
Vakawanda vakawanda vanoita webhutereji yepa internet vanogadzira hardware yakakodzera yemodhi kune vatengi vavo pasina chavanobhadhara kana pamutengo wemwedzi. Kunyange zvakadaro, mienzaniso yemitengo inogona kutengwa kuburikidza nekutengesa zvikwata.
