Wi-Fi-umzila - ntoni na?

Okwangoku, phantse zonke izixhobo enxulumene intanethi, ziyafumaneka kunye iimodyuli eyakhelwe-ngaphakathi ye wi-fi. Umbuzo ophakamayo, kutheni kwenziwa. Impendulo ilula - ukuqinisekisa ukuba ezi zixhobo nako ukudibanisa kwinethiwekhi Internet, nto leyo isasazwa ngoncedo imizila. Ngoku makhe ndizame ukuqonda kancinci lo mbuzo olandelayo: "? Wi-Fi-umzila - yintoni".

Esi sixhobo kwakhona kuthiwa umzila sisixhobo ezithwala idatha eyafunyanwa phakathi kwiindawo womnatha ezahlukeneyo, kunye nokumisela indlela kakhulu kangangoko ngenxa yezithuthi yomsebenzisi. Yavelisa channel eyakho ekwabelwana kunye Internet isasaze ukuba iidilesi inethiwekhi yangaphakathi. Ezi dilesi kukwadala ngokwakhe.

Eyona njongo ephambili umzila kukuzisa kunye ezahlukeneyo izixhobo - PC, laptops, amacwecwe, njl - in komnatha ophinyeneyo ukuze ukusebenzisa ijelo elinye ye Internet.

Siye sifunde ngendlela emfutshane impendulo yalo mbuzo: "wi-fi umzila - ntoni na?". Kwiminyaka yakutshanje, nzima ukufumana i-ofisi, indawo yokutyela, cafe okanye enye indawo kawonke apho kuya ukusebenza lo iteknoloji engenazingcingo phambili. Phantse wonke undwendwe yeziko encothula bakhe laptop yakho, tablet okanye smartphone ukukhangela email ubuncinane. Ngokukodwa ekubeni le nkonzo idla ngaphandle kwentlawulo. Emva uzama ukusebenzisa oko, abaninzi ekhaya uzithengele umzila. Yintoni na, kuba inkoliso yazo akukho mbuzo. Ngoku ungakwazi noba ukuthenga TV kunye eyakhelwe-ngaphakathi Wi-Fi-receiver.

Masithi isigqibo ukuthenga Wi-Fi-umzila. Kuthetha ukuthini? Kwanele ukuba eze evenkileni ukuthenga isixhobo lokuqala-nazo? Hayi, kakade! Okokuqala, kufuneka wenze ukhetho olufanelekileyo.

Okokuqala, simele sinikele ingqalelo kwinethiwekhi yokufikelela protocol, enika umboneleli. Le ingaba PPTP, uHlelo kunye L2TP. Asingabo bonke, ngokukodwa yokugqibela, zixhaswa yi zonke imizila. Fumanisa ngokuyimfuneko ukuze ke ukuba ukubaleka kwakhona evenkileni ukuba iyunithi exchange.

Okwesibini, isigqibo mali ukwenzela ukuthenga. iimveliso Central Asia abiza kakhulu, kodwa mgangathweni, kwanokuba imali logo ezaziwayo-kakuhle. Ngoko ke kungcono ukuba ukuthenga isixhobo kwivenkile elektroniki elikhulu kwaye hayi kunomathotholo, ezibizayo.

Okulandelayo, oko kufuneka wenze isigqibo sixhomekeke kwiimfuno zakho. Yinto enye into ukuphanda umba lowo: "? Wi-Fi-umzila - yintoni na kwaye yintoni na ukuba", Thenga isixhobo ithafa kwaye betyhila i-Internet ngesantya 5 Mbit / s, yaye omnye - kwi-20 ngesantya Mbit / s ukudlala umdlalo intanethi. Kukho sele umzila enamandla ngakumbi iyafuneka, ukuze akwazi ukuphatha kakuhle ngesantya esiphezulu.

Kukho imigangatho ezahlukeneyo wi-fi, yeyona ixhaphakileyo babo yaye ubhetyebhetye - 802.1g. Kukho abanye, bit prozondiruyte yaye lo mxholo.

Ukuba uceba ukukhuphela eninzi umxholo, nikelani ingqalelo kwimali RAM nesantya kumqhubekekisi. Kufuneka ibe ngaphantsi kwe ngokulandelelana, 64Mb kunye 400Mhz.

Kwaye phezu kwinqanaba lokugqibela kukhetho phawula protocol indawo isiciko kunye encryption. Ngoko ke, mhlawumbi, izikhombisi angenjenjalo ezibalulekileyo njengoko engaphambili, kunjalo ...

Apha ukuphendula umbuzo wokuba ingaba, Wi-Fi-umzila, yintoni na. Kokuba kuchaziwe ukhetho ngokwabo okanye ngoncedo eengcali, sikwazi ukuya evenkileni uze uthenge ngokwam esinye isixhobo hi-zobugcisa.
