Ese modem y'urumuri ihujwe na switch cyangwa router mbere na mbere

Banza uhuze router.

Modem y'urumuri ibanza guhuzwa na router hanyuma igahuzwa na switch, kuko router igomba gutanga ip, kandi switch ntishobora, bityo igomba gushyirwa inyuma ya router. Niba bikenewe kwemeza ijambo ry'ibanga, birumvikana ko ugomba kubanza guhuza na WAN port ya router, hanyuma ugahuza na switch ivuye kuri port ya LAN.

Uko injangwe yoroheje ikora

Modemu ya baseband igizwe no kohereza, kwakira, kugenzura, guhuza, gukora, gukoresha porogaramu, gutanga amashanyarazi n'ibindi bice. Igikoresho cya terminal y'amakuru gitanga amakuru yoherejwe mu buryo bwa binary serial signal, kikayahinduramo urwego rwa logic y'imbere binyuze muri interface, kikayohereza mu gice cyo kohereza, kikayihinduramo ikimenyetso cyo gusaba umurongo hakoreshejwe circuit modulation, hanyuma kikayohereza ku murongo. Igice cyakira cyakira ikimenyetso kivuye ku murongo, kikagisubiza ku kimenyetso cya digitale nyuma yo kuyungurura, guhindura inverse, no guhindura urwego, hanyuma kikayohereza ku gikoresho cya digitale terminal. Modemu ya optique ni igikoresho gisa na modemu ya baseband. Gitandukanye na modemu ya baseband. Gihujwe n'umurongo wa optique fibre kandi ni ikimenyetso cya optique.

Itandukaniro riri hagati ya modem y'urumuri, switch na router

1. Imikorere itandukanye

Akamaro ka modem y'ikoranabuhanga ni uguhindura ikimenyetso cy'umurongo wa telefoni kikaba ikimenyetso cy'umurongo w'itumanaho kugira ngo gikoreshwe kuri interineti ya mudasobwa;

Akamaro ka router ni uguhuza mudasobwa nyinshi ukoresheje umugozi wa interineti kugira ngo habeho guhuza kuri interineti, kumenya mu buryo bwikora kohereza amakuru no kuyashyira mu bikorwa, kandi ifite imikorere ya firewall. Muri zo, mudasobwa nyinshi zisangiye konti ya interineti, interineti izagira ingaruka kuri buri imwe.

Akamaro k'iyi switch ni uguhuza mudasobwa nyinshi n'umugozi umwe wa network kugira ngo ikore imikorere ya internet icyarimwe, nta kazi ka router.

2. Imikoreshereze itandukanye

Iyo modem y'urumuri igeze kuri fibre y'urumuri mu rugo, switch na router bikora kuri LAN, ariko switch ikora kuri layer y'amakuru, naho router igakora kuri layer y'urumuri.

3. Imirimo itandukanye

Mu magambo make, modemu ya optique ingana n'uruganda rukora porogaramu ntoya, router ingana n'igurisha rigurishwa mu bucuruzi bunini, naho switch ingana n'isosiyete icuruza ibikoresho. Ikimenyetso cya analog cyoherezwa binyuze mu mugozi usanzwe wa network gihindurwamo ikimenyetso cya digitale na modemu ya optique, hanyuma ikimenyetso cyoherezwa kuri mudasobwa binyuze kuri router. Iyo umubare wa mudasobwa urenze umurongo wa router, ugomba kongeramo switch kugira ngo wongere uburyo bwo guhuza.

Bitewe n'iterambere ry'itumanaho rya fibre optique, igice cya modemu optique zikoreshwa n'abakoresha ubu zifite imikorere yo gukwirakwiza amakuru.
