Kodi modemu yowunikira ndiyo yolumikizidwa koyamba ku switch kapena rauta?

Lumikizani rauta kaye.

Modemu yowunikira imalumikizidwa koyamba ndi rauta kenako ndi switch, chifukwa rauta imafunika kugawa ip, ndipo switchyo singathe, kotero iyenera kuyikidwa kumbuyo kwa rauta. Ngati kutsimikizira mawu achinsinsi kukufunika, ndithudi, choyamba lumikizani ku doko la WAN la rauta, kenako lumikizani ku switch kuchokera ku doko la LAN.

Momwe mphaka wopepuka amagwirira ntchito

Modemu ya baseband imapangidwa ndi kutumiza, kulandira, kulamulira, mawonekedwe, gulu logwirira ntchito, magetsi ndi zina. Chipangizo cholumikizira deta chimapereka deta yotumizidwa mu mawonekedwe a chizindikiro cha binary serial, chimachisintha kukhala mulingo wamkati wa logic kudzera mu mawonekedwe, ndikuchitumiza ku gawo lotumiza, kuchisintha kukhala chizindikiro chopempha mzere ndi dera losinthira, ndikuchitumiza ku mzere. Chipangizo cholandirira chimalandira chizindikiro kuchokera ku mzere, kuchibwezeretsa ku chizindikiro cha digito pambuyo pochisefa, kusintha kosintha, ndi kusintha kwa mulingo, ndikuchitumiza ku chipangizo cholumikizira digito. Modemu yowunikira ndi chipangizo chofanana ndi modemu ya baseband. Ndi yosiyana ndi modemu ya baseband. Imalumikizidwa ndi mzere wodzipereka wa ulusi wa kuwala ndipo ndi chizindikiro chowunikira.

Kusiyana pakati pa modemu ya kuwala, chosinthira ndi rauta

1. Ntchito zosiyanasiyana

Ntchito ya modemu yowunikira ndikusintha chizindikiro cha mzere wa foni kukhala chizindikiro cha mzere wa netiweki kuti chigwiritsidwe ntchito pa intaneti ya kompyuta;

Ntchito ya rauta ndi kulumikiza makompyuta angapo kudzera pa chingwe cha netiweki kuti azitha kulumikizana pa intaneti, kuzindikira zokha kutumiza mapaketi a data ndi kugawa maadiresi, komanso ili ndi ntchito yoteteza moto. Pakati pawo, makompyuta ambiri amagawana akaunti ya broadband, intaneti imakhudzana.

Ntchito ya switch ndikulumikiza makompyuta angapo ndi chingwe chimodzi cha netiweki kuti ntchito ya intaneti igwire ntchito nthawi imodzi, popanda ntchito ya rauta.

2. Ntchito zosiyanasiyana

Pamene modem ya kuwala ifika pa ulusi wa kuwala kunyumba, chosinthira ndi rauta zimagwira ntchito pa LAN, koma chosinthira chimagwira ntchito pa layer yolumikizira deta, ndipo rauta imagwira ntchito pa layer ya netiweki.

3. Ntchito zosiyanasiyana

Mwachidule, modemu ya kuwala ndi yofanana ndi fakitale ya subassembly, rauta ndi yofanana ndi wogulitsa wogulitsa zinthu zambiri, ndipo switch ndi yofanana ndi wogulitsa zinthu. Chizindikiro cha analog chomwe chimatumizidwa kudzera pa chingwe cha netiweki wamba chimasinthidwa kukhala chizindikiro cha digito ndi modemu ya kuwala, kenako chizindikirocho chimatumizidwa ku PC kudzera pa rauta. Ngati chiwerengero cha ma PC chapitirira kulumikizana kwa rauta, muyenera kuwonjezera switch kuti mukulitse mawonekedwe.

Ndi chitukuko cha kulumikizana kwa ulusi wa kuwala, gawo lina la ma modemu owonera omwe amagwiritsidwa ntchito ndi ogwiritsa ntchito tsopano ali ndi ntchito zoyendetsera.
