Igama elithi intanethi lihlala liqhagamshelwe kwimigaqo yomzila kunye nemodem (imodyuli/idemodulator). Kodwa uninzi lwabantu ngokubanzi luyabhideka, ngaba zombini i-router kunye nemodem ziyafana? Ngaba benza umsebenzi ofanayo? Ukuba akunjalo, zahluke njani enye kwenye?
Ke, ukusombulula le ngxaki yabantu, kweli nqaku, uya kufunda malunga nemodem, irutha, ukusebenza kwabo, kunye nomahluko omkhulu phakathi kwezi zimbini.

Yintoni uMahluko phakathi kweRouter kunye neModem?
Ewe, kukho umehluko phakathi kwemodem kunye ne-router kwaye ilula kakhulu. Imodem yenye eqhagamshela kwi-intanethi kwaye irutha yenye eqhagamshela isixhobo sakho kwi-Wi-Fi ukuze ukwazi ukufikelela kwi-intanethi ngokulula. Ngamafutshane, i-router idala uthungelwano phakathi kweekhomputha kunye nezinye izixhobo ezikhoyo kwikhaya lakho ngelixa imodem idibanisa loo nethiwekhi kwaye ngoko, iikhomputha zakho kunye nezinye izixhobo kwi-intanethi. Zombini zizinto eziyimfuneko zokufikelela kwi-intanethi engenazingcingo kunye neentambo ekhayeni lakho okanye nakweyiphi na enye indawo. Ngoku, makhe sifunde ngakumbi malunga nemodem.
Imodem
Igama elithi modem limele imodyuli/imodareyitha . Imodem sisixhobo sehardware okanye inkqubo eguqula idatha phakathi kwemidiya yosasazo ukuze idluliselwe ukusuka kwesinye isixhobo ukuya kuso nasiphi na esinye isixhobo. Ivumela ikhomputha ukuba ithumele idatha kwimigca yefowuni, iintambo zentambo njl.njl usebenzisa iimpawu ze-analog. Idatha igcinwa kwizixhobo ezinjengeekhompyuter ngokwedijithali, kodwa xa zigqithiselwa, zikhutshelwa ngendlela yamaza e-analog okanye imiqondiso.
Imodem iguqula idatha yedijithali ekhoyo kwikhompyuter ibe ngumqondiso olungelelanisiweyo wombane wokuhanjiswa kwizixhobo ngeentambo zentambo kwaye lo mqondiso wombane uthotywe kwicala lomamkeli ngeModem ukuze ikwazi ukufumana kwakhona idatha yedijithali.
Isebenza njani iModem?
Imodem idla ngokuba nayo izibane / ii-LEDs phambi kwabo ukuze ukwazi ukubona ngokulula okwenzekayo ngalo mzuzu.
Ngokusisiseko, kukho izibane ezine / ii-LED ezifumanekayo ngaphambili kwimodem esebenza ngeenjongo ezahlukeneyo.
- Isibane esinye sibonisa ukuba iyunithi ifumana amandla.
- Okunye ukukhanya kubonisa ukuba imodem ifumana idatha kumnikezeli wenkonzo ye-intanethi (ISP).
- Eyesithathu ibonisa ukuba imodem ithumela ngempumelelo idatha.
- Eyesine ibonisa ukuba izixhobo ezixhunyiwe zifikelela kwi-i
Ngoko, ngo ukubona ukuba yeyiphi i-LED okanye ukukhanya okusebenzayo okanye ukuqhwanyaza, ungabona ngokulula ukuba imodem yakho yenza ntoni ngoku okanye yintoni ngoku engena ngaphakathi kuyo. Ukuba ukuthumela okanye ukufumana izibane ziyadanyaza, oko kuthetha ukuba umboneleli wakho wenkonzo ye-intanethi unemiba ethile kwaye kufuneka udibane nayo.
Imodem iqhagamshela umthombo we-intanethi ukusuka kwi-ISP ukuya kwikhaya lakho okanye kwezinye iindawo apho ufuna ukufikelela khona kwisixhobo se-intanethi usebenzisa iintambo ezifana neComcast, ifiber optics, isathelayithi okanye naluphi na uqhagamshelo lwefowuni yokucofa. Iinkonzo ezahlukeneyo zineentlobo ezahlukeneyo zeemodem kwaye awukwazi ukuzitshintsha.
Ukufikelela kwi-intanethi kwiindawo ezisemaphandleni apho kukho iintambo zomnxeba kodwa akukho nkxaso yeenkonzo ezisekelwe kumabonwakude nakwi-intanethi, I-DSL isetyenziswa endaweni yeentambo zangoku ezicothayo.
Iinzuzo kunye neengozi zeModem
IiPros
- Idibanisa kwi I-ISP .
- Ukuhambelana kwe-ISP
- Iguqula isignali yedijithali ibe yisignali ye-analog yokudluliselwa kwintambo.
Ububi
- Ayinakudala inethiwekhi yendawo kwaye iqhube i-Wi-Fi.
- Ayidibanisi izixhobo ezininzi kwi-intanethi.
Kwakhona Funda: Yintoni umqhubi wesixhobo?
Umzila
I-router sisixhobo sothungelwano eso idlulisela iipakethi zedata phakathi kothungelwano lwekhompyuter . Ngokusisiseko, a umzila yibhokisi encinci edibanisa iinethiwekhi ezimbini okanye ngaphezulu njenge-intanethi kunye nomsebenzi womnatha wendawo. Idatha ethunyelwe yi-intanethi njenge-imeyile okanye naliphi na iphepha lewebhu likwimo yeepakethi. Ezi pakethi ke zigqithiselwa ukusuka kwenye irutha ukuya kwenye irutha nge-intanethi de ifike kwindawo ekuyiwa kuyo. Xa ipakethi yedatha ifikelela kuyo nayiphi na yale migca, irutha ifunda idilesi yendawo ekuyiwa kuyo yaloo pakethi yedatha kwaye iyigqithisele kuthungelwano olulandelayo ukuya kwindawo yayo.
Olona hlobo luqhelekileyo lweerotha zii-router zasekhaya okanye iirotha zeofisi. Iirotha zizixhobo ezizimeleyo. Iirutha zinekhowudi ezinikeleyo, enemibala Ethernet port eyisebenzisayo ukudibanisa ngokwasemzimbeni kwi-router efana I-WAN (inethiwekhi yendawo ebanzi) kunye nezibuko ezine ze-Ethernet ezongezelelweyo ze-LAN (inethiwekhi yendawo yendawo).
Isebenza njani iRouter?
I-router iza kubo bonke ubungakanani kunye namaxabiso. Ezi zingenazingcingo ziquka ii-eriyali ezimbini zangaphandle okanye ngaphezulu ngokuxhomekeke kwimodeli. Kwakhona, isantya sokuqhagamshelwa kwe-router sixhomekeke ekusondeleni kwe-router.
Ukusebenza kwe-router kulula kakhulu. Idibanisa iinethiwekhi ezininzi kunye neendlela zetrafikhi yenethiwekhi phakathi kwazo. Ukuqonda ukusebenza kwe-router ngamagama alula, khawufane ucinge i-router njengomlamli phakathi kwe-intanethi kunye nenethiwekhi yendawo. I-router ikwabonelela ngokhuseleko kwizixhobo zakho ukuze zingavezwa ngokuthe ngqo kwi-intanethi. Awukwazi ukuqhagamshela ngqo kwi-intanethi usebenzisa i-router nje. Endaweni yoko, i-router yakho kufuneka isetyenziswe ngokudibeneyo neModem njengoko ihambisa itrafikhi kuqhagamshelo lwe-intanethi.
Iinzuzo kunye neengozi zeRouter

Umahluko phakathi kweModem kunye neRouter
Ngezantsi kukho umahluko phakathi kwemodem kunye nerouter.
1. Umsebenzi
Imodem ifana nomguquleli phakathi kwe-intanethi kunye nenethiwekhi yendawo. Imodem imodareyitha umqondiso wombane kwisignali yedijithali kwaye ithobe isiginali yedijithali ibe ngumqondiso we-analog ngelixa i-router idala inethiwekhi kwaye ivumela izixhobo ezininzi ukuba zidibanise kule nethiwekhi.
Ukuba unesixhobo esinye kuphela, awudingi nayiphi na i-router. Imodem ine-Ethernet port kunye nekhompyuter okanye nasiphi na esinye isixhobo sinokuqhagamshela ngqo kule port ye-Ethernet kwaye ifikelele kwi-intanethi. Kodwa ukuba unezixhobo ezininzi, ngoko unokuqhagamshela kwi-intanethi usebenzisa inethiwekhi eyenziwe yi-router kwaye unokuqhagamshela kwi-intanethi.
2. Uqhagamshelwano
Imodem inezibuko elinye kuphela kwaye inokunxibelelana nesixhobo esinye ngexesha oko kukuthi ikhompyuter okanye irutha. Ke, ukuba unezixhobo ezininzi, awukwazi ukuzidibanisa zonke usebenzisa imodem. Kungenxa yoko le nto kufuneka i-router.
Ngokuchasene noko, i-router inokuqhagamshela kwizixhobo ezininzi ngexesha nokuba ngeentambo ze-Ethernet okanye i-Wi-Fi.
3. Ukhuseleko
Akukho sixhobo sokhuseleko esakhelwe ngaphakathi kwiModem kwaye ayiskeneli idatha yayo nayiphi na ingozi yokhuseleko. Ke, inokudlulisa izoyikiso kuzo zonke iikhompyuter eziqhagamshelwe.
Ngelixa i-router iqulethe i-firewall efanelekileyo ukunika ukhuseleko. Ijonga ngokufanelekileyo iipakethi zedatha ukumisela indawo eya kuyo kwaye ithintele naluphi na uhlaselo ekungeneni kwizixhobo ezixhunyiwe.
4. Ukuzimela
Imodem inokusebenza ngaphandle kwayo nayiphi na i-router kwaye inokubonelela ngoqhagamshelo lwe-intanethi kwisixhobo esinye.
Ngakolunye uhlangothi, i-router inokwabelana ngolwazi phakathi kwezixhobo ezininzi kodwa ayikwazi ukubonelela nge-intanethi kwezi zixhobo ngaphandle kwemodem.
5. Uhlobo lwesixhobo kunye nomaleko
Imodem sisixhobo esisekwe kwi-intanethi esisebenzisa umaleko wesibini o.k.t umaleko wekhonkco ledatha .
I-router sisixhobo sothungelwano esisebenzisa umaleko wesithathu oko kukuthi umaleko womnatha.
Ingaba ufuna nini imodem okanye iRouter?
Ukuseta inethiwekhi yasekhaya, zombini imodem kunye nerutha ziyafuneka. Ukuba uqhagamshela isixhobo esinye kwi-intanethi ngocingo, ufuna imodem kuphela ngelixa kungekho meko enjalo apho ungasebenzisa i-router nje. Uya kusoloko kufuneka usebenzise iModem ngokudibeneyo neNdlela ukuze ukwazi ukucacisa uphawu olusuka kumnikezeli wakho wenkonzo ye-intanethi (ISP).
Ukuba sele usebenzisa imodem kodwa awufumani isantya esifunekayo kwi-ISP ngoko ungasebenzisa iRouter ukukhawulezisa inethiwekhi yakho. Inemida ye-bandwidth kwaye ijikeleza isignali kuzo zonke izixhobo ezixhunyiwe. Ngokusisiseko, into eyenziwa yi-router yakho kukuba idala uqhagamshelo olungenazingcingo kwaye ilawula i-Wi-Fi yakho (i-Intanethi).
Ke, konke oku kumalunga nemodem kunye nerouter kunye nomahluko phakathi kwezi zimbini.
