Ukukhetha imodem ilinda laptop. iingcebiso ezimbalwa kwabasaqalayo

ubugcisa bale mihla eyayimi ngxi kwaye eguqukayo. Oku kubangelwa ikakhulu yokuba nyaka ngamnye iimfuno zomsebenzisi PC ikhula rhoqo, kunye nabavelisi bezixhobo ezahlukeneyo bazama ukwanelisa ezo mfuno. Umzekelo, laptops namhlanje baye baba kukhanya compact ngakumbi, bavumele abanini bawo ukuba basebenze yeselula lwekhompyutha, phantse naphi na. Kodwa yintoni eyenza ingqiqo ukuba nencwadi mobile compact, ukuba elidityaniswe kuyo kwi Internet nge intambo?

Ukuze wenze le ukufuna ulwazi kwi web lonke ezisebenzisekayo ngakumbi, ngaphezu kweminyaka elishumi eyadlulayo, le imodem sokuqala laptops akhululwa, nto leyo eye ngokuqhubekayo ngcono. Baluncedo kuphela uqhagamshelo ekhawulezayo nelula kwinethiwekhi ngaphandle ngumsina nasekunqandeni intshukumo eentsontelo kunye neengcingo, kodwa compactness yayo. Modern laptop modem ngokulula ukungena engxoweni laptop, epokothweni okanye esipajini. Kodwa ke ukugqithisela ibalulekileyo kule fowuni na ukuhamba - ngoncedo wayo umsebenzisi unokusithintela e-mail okanye undwendwele iphepha yakhe yenethiwekhi yoluntu ukusuka nakuwuphi na indawo.

Ngoku makhe sikhangele ukuba ukhethe njani imodem ilinda laptop, yaye ziziphi iintlobo zezi zixhobo ngokubanzi ingafunyanwa kwi kwimarike namhlanje. Ngokutsho uhlobo lonxibelelwano kwi laptop yakho imisiwe zonke izixhobo ezo zingahlulwa ngokweendidi ezintathu: USB-Iimodem, PCI babonakalisa-amakhadi kunye imizila mobile.

Namhlanje, yeyona ndlela isetyenziswa kakhulu USB-imodem. Kwathi ngenxa ngani zingenakuphikwa - lula uqhagamshelwano, compactness kunye nsimbi. PCI express-cards ngoku ngenkankulu kusetyenziswa (laptops ezininzi mihla zizonke izi- kwiindawo zokubeka kwabo), kodwa ubukhulu becala ziphumelela lwe USB-imodem ngokwemiqathango ergonomics. Oku kungenxa yokuba ukuba imodem onjalo ukuba laptop emva kokuqhagamshelana phantse ngokupheleleyo "abarhaxwa" kwi kumzimba laptop, ngexa ifowuni idityaniswe nge USB, yabaxhasi isoloko bokuhamba bayacalulwa iikhompyutha iisentimitha ubuncinane ezimbalwa.

Eyahlukeneyo imodem "mobile" kunye nezinga data. Lolona hlobo luqhelekileyo inxaxheba kurhwebo lwasemakhaya ngoku ekubeni izixhobo ezisebenzisa iteknoloji 3G - inikeza ngenxa yale ndlela udlulisela le data wireless ngoku asifumaneki phantse umqhubi zonke asethi. 3G-imodem yamanqaku ivumela umnikazi wayo ukusebenzisa Internet ngesantya ukuya ku-8 Mbit / s. Nangona kunjalo, isantya ngqo iya kwahluka kakhulu umgangatho ukutyabeka kumqhubi, isantya ikhonkco avareji kwindawo yokwamkela iindwendwe kunye nenani nezinye izinto. A uhlobo lonxibelelwano ngokukhawuleza i iteknoloji ebizwa «WiMAX», unako ukusebenza ngesantya ukuya ku-10 Mbit / s. Kwaye ke sisombululo "slow" kwimarike namhlanje netheknoloji nge 450 ( "isilingi" yayo - kuphela 3.1 Mbit / s).

Phambi kokuba uthenge isixhobo efana imodem ilinda laptop, qiniseka ukuba umfuziselo olukhethiweyo ilungele ukuba laptop kwindlela yakho yokusebenza. Kungenjalo, xa uqhagamshele modem ukuze iingxaki ngofakelo abaqhubi kunye isixhobo operability ngokubanzi. Ukuba ugqiba ekubeni ukuthenga uqhagamshelwano modem (kungena kwisivumelwano kunye enye ababoneleli beeselula yokubonelela ngeenkonzo ukufikelela Internet), musa ukulibala ukuba uqinisekise ukuba unayo i-inshorensi esemgangathweni kwiindawo apho uya khona ukuba basebenzise iinkonzo yomboneleli. Oku kungenxa yokuba i-Internet mobile - into kakhulu abangenazigqibo, kwaye umgangatho coverage yayo (kwaye, ngenxa yoko, wafumana ngenxa nesantya) inokuchaphazela nkqu Ebubanzini iindonga endlwini. Ngoko ke, ngaphambi kokuba uthenga isixhobo enjalo qiniseka ukuba ubonane ummeli wenkampani ukusebenza.
