Ukukhetha imodemu okwesikhathi laptop. izincomo eziningana Wabasaqalayo

Ubuchwepheshe banamuhla akuyona emi namanje futhi njalo elokhu ivela. Lena ngokuyinhloko ngenxa yokuthi njalo ngonyaka izidingo PC umsebenzisi ezikhulayo njalo, futhi abakhiqizi ezahlukene zamadivayisi uzame ukuzanelisa lezo zidingo. Ngokwesibonelo, ama-laptops sanamuhla baye baba lula futhi emfishane, okuvumela zabanikazi ukusebenza kukhompyutha mobile enjalo, cishe noma kuphi. Kodwa yini eyenza umqondo ukuba nencwajana yokubhalela mobile ezihlangene, uma ixhunywe ku-Inthanethi nge ikhebula?

Ukuze wenze search ukuze uthole ulwazi kuwebhu emhlabeni wonke ezisebenzisekayo ngaphezulu, eminyakeni engaphezu kweyishumi edlule, modems lokuqala laptops badedelwa, eye ngokuqhubekayo ngcono. Ayasiza uxhumano hhayi kuphela esheshayo futhi elula inethiwekhi ngaphandle nzima kanye nokunciphisa ukuhamba ngezintambo, izintambo, kodwa futhi compactness yayo. Modern laptop imodemu kalula angena esikhwameni se-laptop, ephaketheni noma esikhwameni. Kodwa inzuzo ebaluleke kakhulu le divayisi ukuhamba - ngosizo yayo umsebenzisi angakwazi uhlole i-imeyli noma vakashela ikhasi lakhe yokuxhumana cishe kunoma iyiphi indawo.

Manje ake sibheke indlela ukukhetha imodemu ngoba i-laptop, kanye nokuthi yiziphi izinhlobo zalezi amadivaysi ngokuvamile zingatholakala emakethe namuhla. Ngokusho uhlobo uxhumano laptop yakho imisiwe wonke amadivayisi ezinjalo kungenziwa ihlukaniswe izigaba ezintathu: i-USB modems, PCI express-amakhadi kanye imizila ephathekayo.

Namuhla, kabanzi kunazo-USB modems. Kwenzeka ngoba amathuba abo obungenakuphikwa - kalula uxhumano, compactness nezindlela ezihlukahlukene zokusisebenzisa. PCI express-amakhadi manje neze esetshenziswa (laptops eziningi zanamuhla ngokuphelele elingenalo nezikhala kubo), kodwa ngokuyinhloko ziphumelela kangcono kwesitoreji-modems ngokuya Ergonomics. Lokhu kungenxa yokuthi ukuthi imodemu enjalo okwesikhathi laptop ngemva kokuxhuma cishe ngokuphelele "waminza" emzimbeni we laptop, ngesikhathi idivayisi ixhunyiwe nge-USB, cishe ngaso sonke isikhathi bokuhamba zinganakiwe ikhompuyutha amasentimitha okungenani ambalwa.

Ezahlukene modems "mobile" nedatha izinga. Uhlobo oluvame kakhulu emakethe yasekhaya manje kubhekwe ukuba amadivayisi usebenzisa 3G ubuchwepheshe - inikeza ngesisekelo le ndlela wireless ukudlulisa idatha seziyatholakala cishe kuwo wonke opharetha kwempahla. 3G-imodemu ngoba notebook evumela umnikazi walo ukusebenzisa i-intanethi ngesivinini-8 Mbit / s. Nokho, ijubane uqobo ngeke buhluke kakhulu opharetha enamathela izinga, ngokwesilinganiso isixhumanisi ijubane endaweni okufikela kuyo izingcingo bese eziningi nezinye izinto. Indlela esheshayo uhlobo loxhumano ubuchwepheshe ngokuthi «WiMAX», ungasebenza ngesivinini abafika kwabangu-10 Mbit / s. Futhi iningi "kancane" isixazululo emakethe namuhla ubuchwepheshe CDMA 450 ( "uphahla" yayo - 3.1 Mbit kuphela / s).

Ngaphambi kokuba uthenge leli thuluzi njengemodemu okwesikhathi laptop, qiniseka ukuthi imodeli akhethiwe kufanelekile isistimu yakho yokusebenza laptop. Uma kungenjalo, uma uxhuma imodemu angase abe nezinkinga ukufakwa abashayeli kudivayisi operability bebonke. Uma unquma ukuthenga uxhumano imodemu (ngokufaka esivumelwaneni omunye opharetha mobile okuhlinzeka Ukufinyelela i-Inthanethi amasevisi), ungakhohlwa qiniseka ukuthi ikhava izinga ezindaweni lapho uya ukusebenzisa umhlinzeki. Lokhu kungenxa yokuthi i-Inthanethi ephathekayo - into ngempela ezingezwakali, futhi izinga ekuhlanganiseni kwaso (futhi, ngenxa yalokho, wathola ngenxa ijubane) kungathinta ngisho ukushuba we izindonga endlini. Ngakho-ke, ngaphambi kokuthenga idivayisi ezifana qiniseka ubonane ummeleli wenkampani ezisebenza.
