Wireless: yintoni kubuchwepheshe computer?

Kutshanje, umbuzo ngakumbi phakathi abasebenzisi ezinjengeetheminali computer, laptops okanye izixhobo mobile: "Wireless - ntoni na?". Makhe sijonge esi sihloko kwaye ezinye iinkcazelo esisiseko.

Wireless: oko ngengqiqo jikelele?

Push off ukuqala aya kususela iinkcazelo ze ukuguqulela amazwi IsiNgesi. Oku wabumba kwicingo elithi (USB, intambo, ucingo) kunye ukuvalwa -ana, leyo xa kongezwa igama original 'ukungabikho', ' "ibe t. D.

Enyanisweni, ngenxa yoko kunokwenziwa isigqibo ukuba wireless, enyanisweni, lithetha "ngeengcingo." Namhlanje yinto enjalo awusasebenzi kwiinkqubo zonxibelelwano kunye nokufikelela kwi-Internet. Ngubani ongazange weva Wi-Fi? Kodwa uthungelwano enjalo ingachazwa ncam yi elithi "ngaphandle kweengcingo".

Yintoni i-adaptha Wireless: nezimaphambili ezingundoqo kunye neentlobo

Ngokumalunga amaqhoshana ezo zisetyenziselwa unxibelelwano zintambo, aziwayo kakhulu ke imizila, ADSL-imodem kunye ezimanyanisiweyo Wi-Fi, USB-iadaptha, kwakunye amacandelo ezisemgangathweni ngokusekelwe PCI ibhasi zifakwa, umz, kwi iikhompyutha zokubhala, Wi-Fi -modules e zobuchwepheshe mobile, kwakunye uxhulumaniso kuthetha nge Bluetooth (ke andingowawo udidi iteknoloji engenazingcingo).

Ayisafuni nakucaciswa yona into yokuba imigaqo yokusebenza zabo ngandlel ezahlukeneyo, ngokunjalo nokufakwa uqwalaselo iindlela. Ngokomzekelo, omnye umzila, kuxhomekeke imodeli, onokusinika lokuhambisa IP-iidilesi kwizixhobo ezininzi, kwaye uluhlu kolundi ka 10-100 m kumnombo emehlweni. USB-iadaptha kunye nezixhobo zokubhala ngayo ngokusekelwe PCI ibhasi elidityaniswe ngqo iikhompyutha okanye laptops kwaye ezinako lonxibelelwano ngeengcingo kuphela ezinjengeetheminali abaqhagamshelwe ngqo. Njengoko sele ngokucacileyo ngesenzo okanye ukufumaneka umqondiso phakathi kwezinye izixhobo abakwazi ukuthetha apha. Nangona ezinye iimodeli ungenza ukwenza unikezelo kwi computer yakho okanye kwi laptop yakho. Kodwa ke umbuzo musa asinakubachukumisa.

iinethiwekhi ze-wireless kwaye imali eyinkxaso

Kwabonakala Le mbono "ngengcingo» womnatha (Wireless Network) ngokwentelekiso kutshanje. Xa sincokola ngayo ubuchwepheshe bee-computer, kukho iindidi eziphambili ezimbini kuqatshelwa networks: Wi-Fi kunye WiMAX.

Ayisafuni nakucaciswa yona into yokuba xa ufaka zonxibelelwano networks abazisebenzisayo ubugcisa ezahlukeneyo. Ngokuqhelekileyo, Wi-Fi networks lufunde ezitsho mvume ekuthiwa-nokunqongophala endaweni engaba coverage, apho ngokuqhelekileyo ayidluli 100 m. Kakade ke, okuninzi kuxhomekeke umthamo kwezixhobo umthengisi, umzekelo, uphawu le umzila.

Kukho enye ingqiqo wireless. Yintoni na ngokwemiqathango yothungelwano WiMAX? Oku, ngaphezu kwabo bonke, ukusetyenziswa rhoqo uphawu transmission mvume nesambatho amashumi yeekhilomitha. Noko ke, phakathi abasebenzisi unazo eziqhelekileyo ezifana Isixokelelwano sokusasazwa ezizodwa abazange bayifumane nje ngenxa yexabiso yalo phezulu (okuthetha izixhobo, ukufakelwa, ukugcinwa, imali, njalo njalo. D.).

Ukuqwalasela umxholo «Wireless :? ntoni na" akunakwenzeka ngoyaba indlela Bluetooth transfer data engasebenzi ngeengcingo. Kakade ke, kwiimeko ezininzi, ukufikelela kwi Internet Iimodyuli ezinjalo ayifaneleki, kodwa ukutshintshwa ngokukhawuleza iifayile data ukungena kakuhle kakhulu. Enyanisweni, kubalulekile ukuqwalasela umda kwirediyasi inyathelo, apho ngokuqhelekileyo ayidluli kweemitha ezili-10.

isiphelo

Nantsi indlela emfutshane leyo a nonxibelelwano engasebenzi ngeengcingo. Kulo mzekelo, siye kuqwalaselwa kuphela ihlabathi computer, kodwa bambalwa ucinge yokuba phones ezihambahambayo uyafana kuyasebenza oko ukubizwa kobuchwepheshe bombane. Nokuba kubomi bemihla ngemihla sijongene nazo phantse yonke imihla. Thatha ubuncinane remote control eziqhelekileyo zombane ekhaya elawulwa-kude. Isebenzisa ithuba lokudlulisela nokufumana uphawu ulawulo olusekelwe phezu izakhono uyezibuko lefoni. Noko ke, ungaqhubeka eli uluhlu ixesha elithile.
