Yintoni i modem? Siseko ukusebenza. iintlobo imodem

Ixesha lokuqala kokuxhuma laptop okanye iPC kwi Internet evela kubasebenzisi embi babelazi, njengoko umthetho, umbuzo othi: "Yintoni na le modem yaye kutheni xa zifuneka," Njengenxalenye yale nqaku liza kunikwa Ukuhlelwa modem, ngokunjalo uya algorithm ukuze ukufakwa kwabo uqwalaselo, enza nto leyo ngokulula ikhompyutha specialist mfundi ungakhetha ufumane basebenze sixhobo.

Yintoni na?

Okokuqala, makhe ukumelana nento yokuba imodem ezinjalo. Eli licandelo okhethekileyo computer, apho yenzelwe uqhagamshelwano womnatha yekhompyutha. Igama elithi "imodem" amiliswe ngokudibanisa amagama amabini. Eyokuqala them - modulator. Ngoko elektroniki olubizwa icebo okhethekileyo, nto leyo buqonda uphawu. Nowesibini - a demodulator. Oko kukuthi, isixhobo eyenza yintshukumo modulator nguqu. Omnye wabo buqonda kwaye edlulisela umqondiso, kwaye eyesibini ufumana nabaguquki. Ngoko ke, kude kube ngoku, ukuya kwi Internet ezininzi computer kwakunxibelelene ngokusebenzisa ezintambo ngomnxeba. Ngoku imeko itshintshile, yaye ngokuthe ngcembe oluphumayo ngaphandle kwicandelo lentengiso amakhadi womnatha. Bona, kwaye isantya iphezulu, yaye inxalenye enkulu motherboard kufakwa nabo. Kodwa kusekho imodem yayo Asikabi nazo omnye ngokwenene.

Xa udinga?

Ngoku makhe ukujongana nezo meko apho zifuneka. Okubalulekileyo, le ngongoma babe ezintathu. Eyokuqala kwezi ngoku ngokucotha shwaka. Yena siqu ikhompyutha ngoncedo le sixhobo kunye yefowuni liqhagamshelene Internet. Ke kaloku uthe wamtyhala NICs. Kwaye ke iindleko lisezantsi, kwaye izinga izihlandlo eziliqela ngaphezulu. Kwaye uqhagamshelwano kulo mzekelo umyalelo yobukhulu ngcono. Kodwa le nkqubo "loNiko-Bank" a isixhobo esinjalo kufanele (kwimeko yesibini). Pomoschm xa elidityaniswe kuyo le zimali womncedisi kwiziko lemali. Ngaphandle kokuba i-ofisi, angenza i transfer imali okanye ukukhangela ukufumaneka kwemali kwi-akhawunti. Isantya esiphakamileyo kule meko ingafuneki. Kodwa uqhagamshelwano ukhuselo iyafuneka kwinqanaba elifanelekileyo. Ngoku imibutho emininzi kule fomati kunye nomsebenzi kunye neebhanki. Ityala yamva, xa imodem kwemfuno, ukuba umntu uhamba lukhulu. Kufuneka uqhagamshelwano intanethi. Kulo mzekelo, lo mbuzo: "Yintoni na le modem, yaye kutheni xa zifuneka" - kuvela ngokwalo. Ngoncedo nezinye iindlela zobugcisa, lo mbuzo nje ayikwazi ukuba kusonjululwe.

Xa indlela uphumezo

Xa indlela uphumezo zixhobo zahlulwe iintlobo ezimbini: yangaphakathi (ngamanye amazwi, ifakelwe ngaphakathi kwinkqubo yekhompyutha i-unit) nangaphandle (ukudibanisa isixhobo eso ukwanda yekhompyutha slot iyasetyenziswa, laptop okanye icwecwe). Kuba yokugqibela, kufuneka ufake i iswitshi yentsimbi (ukuba ikhona) kwi indawo efanelekileyo. Kwaye kufuneka ibe lo mbuzo: "Yintoni na indlela Modem" Ewe yedijithali okanye analog - umiselwa umqondiso ucingo. Iimodem Wireless ifumaneka kuphela kuqala kubo. Zonke nethiwekhi zeselula zisebenza kuphela kulo mgangatho. Ngoko ke, utshintsho olunjalo alufumaneki ukuba iifowuni ezisebenza ngaphandle kweengcingo. Enye ingongoma kufanele kuphawulwe. On motherboards abadala ezihlangeneyo (oko kukuthi, soldered) Izixhobo ezifanayo. Kodwa ke ngoku engasekho zibonwa PC ezintsha.

ngokuba imiyalelo kokuxhuma

Ulwahlulo yesibini, leyo yayiyeyona lonikezelo enkulu, ngokusekelwe indlela wombane. Ngokwale Soup data yahlulwe igxunyekwe nokuba wireless. Kwimeko yokuqala kukho isinxibelelanisi ekhethekileyo intambo ifowuni ifakiwe. izixhobo abadala inokuba yiyo nayiphi intetho efowunini okanye umsebenzi kwi-Internet. Ngoku kukho ukuguqulwa ezizodwa izixhobo ezinjalo. It ikuvumela ukuba ngaxeshanye sefa i-intanethi nokunxibelelana ngefoni. Le ADSL-imodem. Yintoni na? converter Special, leyo yahlula incoko kunye uphawu ngamaza ezitsho ezahlukeneyo. Ngenxa yoko efanayo imilambo ezimbini data idluliselwe intambo. Kwimeko yesibini, ugqithiso lwedata inikwa radiation magnetic ngaphandle ezintambo.

Xa uhlobo lothungelwano ezixhasiweyo

Olu khetho kuphela ngokucalula nokwahlula iifowuni ezisebenza ngaphandle kweengcingo. Ngokutsho kwakhe, ukuba ezi ntlobo zilandelayo: GSM (bona nazo ngamanye amaxesha kuthiwa 2G), 3G kunye lte (4G lelinye igama). Bonke bephela umva ehambelanayo kunye nabanye. Okt 3G kube lula ukusebenza kwi network GSM. Kwakhona, ngoxa abasebenzisi ndandingaluqondi inyaniso yokuba USB-imodem. Kungenxa kule fomu factor ukwenza inkoliso izixhobo ezinjalo. Imbonakalo le flash drive enika iinkcukacha engasebenzi ngeengcingo. Nakanjani oko mayixhotyiswe slot ukuba ikhadi leSIM. Ixhume ku isinxibelelanisi okoxande YUSB PC.

abenzi

Ngokuqhelekileyo, kubavelisi eso sixhobo lungohlulwa lube iiklasi ezimbini. Eyokuqala kuzo - na amagama eemveliso olufikelelekayo kancinane-yaziwa, eziquka Sierra (ixabiso iqala 180 engange) kunye Spirit (ixabiso izixhobo ezinjalo 120-150 engange). Kodwa yesibini iklasi - i izixhobo ezithandwayo kunye ezikumgangatho ophezulu. Bona kuthengiswa phantsi brand Pantech kunye Huawei. Ixabiso sele engange-600 nangaphezulu. Kodwa kuyinyaniso iifowuni ezisebenza ngaphandle kweengcingo. Kudla umbuzo umbuzo, yintoni na 3G-imodem. Esi sixhobo yesikhumbuzo (efana kakhulu intonga Kuyabonakala), nto leyo ifakwe kwi SIM khadi operator mobile kwaye esebenzisa ngayo yenza unxibelelwano kunye Internet. Ngenxa yoko, phakathi izixhobo igxunyekwe esilawulwa "D-Link" yaye "A-Corp". Kucetyiswa ukuba anikele ingqalelo xa uthenga isixhobo esinjalo. Ixabiso ezinye iimodeli kwesi sigaba iqala engange-120. Ubulunga nasici zabo.

ukulungiswa

Qwalasela inkqubo ngokumisela le modem Internet. Yintoni modem Internet? Ezi zonke, ngaphandle kokukhetha, izixhobo kule klasi: zombini seyenziwe futhi engasebenzi ngeengcingo. Ngoko ke, indlela ukuqwalasela:

• Uqhagamshelo. Kuba lwangaphandle - kukuba ukufaka kubo ukwanda slot kwefowuni computing. Kodwa xa ufaka izixhobo lwangaphakathi kufuneka ususe isiciko icala kwinkqubo yekhompyutha lobuqu iyunithi, ukufaka ikhadi ibe slot ukwanda, yilungise ulibizele ndawonye lonke kwakhona.
• Ifaka abaqhubi. Kwiimeko ezininzi kuthatha ngokuzenzekelayo indawo, kunye nokuthatha inxaxheba somsebenzisi kule nkqubo inciphisiwe. Ekupheleni kufuneka ubone umyalezo kwi kukufakwa ngempumelelo the software. (Ukuba ayiwenzi, ngoko ke kufuneka ifakwe ngesandla kwi CD okanye ukusuka kwisayithi web.)
• Okulandelayo, ukudibanisa kwi Internet.
• Ngelo isigaba sokugqibela kusungulwa ibrawuza khangela yokusebenza zo xhulumaniso.

Kwezinye iimeko kuyimfuneko ukulungisa useto devaysa umsebenzi (umzekelo, ukutshintsha indlela yokuqesha analog ukuya digital). Olu lwazi lukhangelwa kunye nomsebenzisi umboneleli kunye mnxeba.

isishwankathelo

Eli nqaku sele iphendulwe kumbuzo yintoni imodem kunye kutheni zifuneka. Ukugximfizwa kunokwenzeka kwezixhobo ezinjalo. Kuboniswe iindlela zokusebenza kunye nezinye iimpawu zobugcisa. Kwakhona ibonisa algorithm yababini, kulandelayo apho kunokwenzeka khona ukuba ngokulula uqwalasele isixhobo loqhakamshelwano kwinethiwekhi.
