Kodi modemu ya kuwala imalumikizidwa ndi chosinthira kapena rauta poyamba

Lumikizani rauta poyamba.

Modemu ya kuwala imalumikizidwa ndi rauta poyamba ndiyeno kusinthira, chifukwa rauta iyenera kugawa ip, ndipo chosinthira sichingathe, chifukwa chake chiyenera kuyikidwa kumbuyo kwa rauta.Ngati chitsimikiziro chachinsinsi chikufunika, ndithudi, choyamba gwirizanitsani ku doko la WAN la rauta, ndiyeno gwirizanitsani ndi chosinthira kuchokera ku doko la LAN.

Momwe mphaka wopepuka amagwirira ntchito

The baseband modem wapangidwa ndi kutumiza, kulandira, ulamuliro, mawonekedwe, gulu ntchito, magetsi ndi mbali zina.Chipangizo chamtundu wa data chimapereka chidziwitso chotumizidwa mu mawonekedwe a chizindikiro cha binary serial, ndikuchisintha kukhala mulingo wamkati wamkati kudzera pa mawonekedwe, ndikuchitumiza ku gawo lotumizira, ndikuchisintha kukhala chizindikiro chopempha mzere ndi dera losinthira, ndikutumiza. ku line.Chigawo cholandira chimalandira chizindikiro kuchokera pamzere, ndikuchibwezeretsanso ku chizindikiro cha digito pambuyo pa kusefa, kusintha kosinthika, ndi kutembenuka kwa msinkhu, ndikutumiza ku chipangizo cha digito.Modem ya kuwala ndi chipangizo chofanana ndi modemu ya baseband.Ndizosiyana ndi modemu ya baseband.Zimalumikizidwa ndi mzere wodzipereka wa fiber fiber ndipo ndi chizindikiro cha kuwala.

Kusiyana pakati pa Optical modem, switch ndi rauta

1. Ntchito zosiyanasiyana

Ntchito ya modemu ya kuwala ndikutembenuza chizindikiro cha foni yam'manja kukhala chizindikiro cha mzere wa intaneti kuti ugwiritsidwe ntchito pa intaneti ya kompyuta;

Ntchito ya rauta ndikulumikiza makompyuta angapo kudzera pa chingwe cha netiweki kuti muzindikire kulumikizana kwapaintaneti, kuzindikira kutumizidwa kwa mapaketi a data ndi kugawa adilesi, ndipo kumakhala ndi ntchito yozimitsa moto.Pakati pawo, makompyuta angapo amagawana akaunti ya Broadband, intaneti idzakhudzana.

Ntchito yosinthira ndikulumikiza makompyuta angapo ndi chingwe chimodzi cha netiweki kuti azindikire ntchito yapaintaneti nthawi imodzi, popanda ntchito ya rauta.

2. Ntchito zosiyanasiyana

Pamene modemu kuwala kupeza CHIKWANGWANI kuwala kunyumba, lophimba ndi rauta ntchito pa LAN, koma lophimba ntchito pa wosanjikiza kugwirizana deta, ndi rauta ntchito pa wosanjikiza maukonde.

3. Ntchito zosiyanasiyana

Mwachidule, modem ya kuwala ndi yofanana ndi fakitale ya subassembly, rauta ndi yofanana ndi wogulitsa malonda, ndipo kusinthako kuli kofanana ndi wogulitsa katundu.Chizindikiro cha analogi chomwe chimaperekedwa kudzera mu chingwe wamba chapaintaneti chimasinthidwa kukhala chizindikiro cha digito ndi modemu ya kuwala, kenako chizindikirocho chimatumizidwa ku PC kudzera pa rauta.Ngati kuchuluka kwa ma PC kupitilira kulumikizana kwa rauta, muyenera kuwonjezera chosinthira kuti muwonjezere mawonekedwe.

Ndi chitukuko cha optical fiber communication, mbali ya modem ya kuwala yomwe amagwiritsidwa ntchito ndi ogwira ntchito tsopano ali ndi ntchito zoyendera.
