I-Modem ne-Router ihluke kanjani?
Umehluko phakathi kwe-modem ne-router ilula: i-modem ikuxhuma kwi-intanethi, kuyilapho um router uxhumanisa amadivaysi akho ku-Wi-Fi. Kulula ukuthola amadivaysi amabili ahlanganiswe uma umhlinzeki wakho wezinsizakalo ze-Inthanethi (i-ISP) akhokhela kokubili njengengxenye yephakheji lakho le-inthanethi.
Ukwazi ukuthi imuphi umehluko phakathi kwemodemu nomzila nokuthi umsebenzi ngamunye ungakusiza kanjani ukuba umthengi ongcono, futhi ugcine imali ngokuthenga imishini yakho, kunokuba ukhokhe imali yenyanga ukuyiqashisa kusuka ku-ISP yakho.
Yiziphi i-Modems
I-modem ixhuma umthombo we-intanethi kusuka ku-ISP yakho nasenethiwekhi yakho yasekhaya, noma ngabe usebenzisa umhlinzeki wekhebula, njenge-Comcast, i-fiber optics, njenge-FIOS, i-satellite, njenge-Direct TV, noma i-DSL noma uxhumano lwefoni lokudayela. I-modem ixhuma ku-router yakho-noma ngqo kwikhompyutha yakho-usebenzisa ikhebula le-Ethernet. Amamodeli ahlukile kunhlobo ngayinye yesevisi; aziguquguquki.
I-ISP izoqasha amamodemu kubhalisele kubo imali yokukhokha, kodwa ama-modem ekhebula ayatholakala ukuthengiswa ngamanani aphansi. Izindleko eziqashiwe ngenyanga zivame ukuzungeze u-$ 10 ngaphezulu ngenyanga; uma uhlela ukugcina isevisi efanayo ngonyaka noma ngaphezulu, ukuthenga i- modem yekhebula ebiza cishe i-$ 100 izokhokha ngokushesha. Qaphela ukuthi i-modems ehambisana ne-FIOS ilukhuni ukufika, ngakho-ke uma kunjalo, kuyasiza ukuqasha eyodwa kusuka ku-Verizon.
Yiziphi Routers Do
Ama-Routers axhuma ku-modem futhi adale inethiwekhi yangasese ekhaya, ehhovisi, noma endaweni yebhizinisi, njengesitolo sekhofi. Uma uxhuma idivaysi ku-Wi-Fi, ixhumeka ku-router yendawo. Leyo router ihambisa wonke amadivaysi akho smart, kuhlanganise smartphone yakho, kodwa futhi izikhulumi smart efana Amazon Echo kanye smart ekhaya imikhiqizo (amabani, izinhlelo zokuphepha). Ama-routers angenantambo akwenza futhi ukuthi usakaze okuqukethwe kwikhompyutha yakho noma idivayisi yeselula nge-Netflix, i-Hulu nokunye okunjalo, ngaphandle kokusebenzisa noma yikuphi izintambo.
Ezinye i-ISP zinikeza amashayela wokuqasha, kodwa ukuthola ubuchwepheshe bamuva, kufanelekile ukuthenga okuqondile. Ukuthenga umzila ongenazintambo kusho ukuthi ungakhetha imodeli efanelekayo ekhaya lakho noma ehhovisi noma unezici eziphambili zokudlala neminye imisebenzi uma udinga.
I-Modem ne-Router Combo Devices
Kukhona futhi ama-modem anezinqola ezididiyelwe ezenza imisebenzi emibili ongayibhadela ku-ISP yakho noma ukuthenga ngokuqondile. Lawa madivaysi ama-combo angase afake umsebenzi we-VoIP uma unekhebula, i-Inthanethi, nefoni. Amadivaysi okuhlanganiswa ngokuvamile akuyona into engcono kunazo zonke ngoba uma ingxenye eyodwa iphela, yonke into ayinalutho, futhi awukwazi ukuthuthukisa idivayisi eyodwa ngesikhathi esisodwa. Noma kunjalo, uma ungadingi i-tech yakamuva futhi enkulu kunazo zonke, ukuthenga i- modem ye-combo ne-router kulula.
Yiziphi Izinethiwekhi Zezingodo?
Kwezinye izimo, umshini owodwa ongenawo ucingo awunelungelo ukumboza yonke indlu noma ihhovisi ngenxa yendawo enkulu noma eyodwa enezakhiwo eziyinkimbinkimbi, izindonga eziningi, noma izindonga ezingenakunyakaziswa. Ukuze ugweme izindawo ezifile, ungathenga izilinganiso zebanga ezixhuma ku-router yakho futhi wandise ukufinyelela kwayo. Noma kunjalo, lokho kuvame ukuchaza ukuhamba komkhawulokudonsa okuncane ngaphansi kwezindawo eziseduze ne-extender, okuguqulela ekuvinjeni okusheshayo nokulanda. Yilapho ukutshala imali kwinethiwekhi yesikhumba kungase kube mnandi.
Inethiwekhi yezintambo ze-Wi-Fi inomgwaqo owodwa oyinhloko nama-satellite amaningana, noma ama-node, ahambisa isibonakaliso esingenazintambo kusuka kolunye kuya kwesinye, njengeketheni. Esikhundleni sezingxube ezikhulumisana kuphela ne-router, ama-network nodes ama-node axhumana nomunye futhi akukho ukulahlekelwa kwe-bandwidth, ngakho-ke isignali inamandla njengokuthi ulungile eduze komgwaqo oyinhloko. Akukho mkhawulo wokuthi zingaki izinombolo ongasetha, futhi ungayiphatha konke usebenzisa i-smartphone. Kungakhathaliseki ukuthi udinga i-extender yobubanzi noma inethiwekhi yesikhumba esekelwe ngobukhulu besikhala sakho nokuthi ngabe udinga umkhawulokudonsa kangakanani.
