Yonke into ofuna ukuyifumana malunga ne-LAN engena-wireless
I-WiFi (nayo ibhaliwe i-Wi-Fi) imele i-Wireless Fidelity. Yona iteknoloji yenethiwekhi engenazintambo evumela ukuba iikhomputha kunye nezinye iifowuni zixhunyelelane zibe yi-LAN kunye ne-Inthanethi ngaphandle kwezintambo kunye nezixhobo. I-WiFi ikwabizwa ngokuba yi-WLAN, emele i-LAN engenawucingo, kunye ne-802.11, eyona ikhowudi yobugcisa yeprotocol.
Kule nqaku, sibheka kwi-WiFi kule migca elandelayo:

Ukubaluleka kweWiFi kunye nokulinganiselwa
I-WiFi inikeza amandla amakhulu ekunxibelelwano kwaye iguqulele ii-LAN emhlabeni jikelele. Ngombulelo kwi-WiFi, abantu abaninzi banokukwazi ukuxhuma kwi-Intanethi kwaye kulula ngokulula. Inzuzo enkulu kunazo zonke ze-WiFi yindlela ekunika ngayo abantu abasebenzisa iikhomputha zeekhomputha kunye nezixhobo eziphathekayo ezifana neefowuni ze-smartphones kunye nee-PDAs - zinokutshintsha ukusuka kwinethiwekhi enye ukuya kwelinye ngaphandle kokuphazamiseka ngeengcingo.
I-WiFi inomlinganiselo othile othe ngqo, kwaye iyona mqobo kuphela. Ekubeni iteknoloji ye- LAN , i-WiFi inikeza indawo yokuxhamla yezinye iinyawo ezininzi. Ngaphandle kweemitha ezingama-20-25, uvele ungaphandle kwenethiwekhi. I-antenna ye-WiFi ithumela amagagasi kuyo yonke indawo ngeenxa zonke. Iimpawu ze-WiFi zilahlekelwa ngamandla njengoko zihamba phambili kude ne-antenna, yingakho umgangatho woxhumo luyancipha njengoko ikhompyutha okanye idivaysi ibeka kude kude nomthombo. Izicelo zokulawula uxhulumaniso lwe-WiFi kwiikhomputha kunye nezinye izixhobo zihlala zinamanqanaba okubamba amandla okuqhagamshelana: ezilungileyo, ezilungileyo, ezihluphekileyo njl.
WiFi Hotspots
I- WiFi hotspot yindawo ejikeleze umthombo we-WiFi (i-router engenantambo, i-antenna ye-WiFi, njl., Ukudala izibonakaliso ze-WiFi) apho ikhompyutha kunye nezixhobo zingaxhuma kwi-WiFi. Ii-Hotspots zifumaneka kwiindawo ezininzi: kwii-campuses, kwiiofisi, kwiivenkile, nakwikhaya. Umzekelo, unokukwazi ukufumana i-WiFi hotspot ekhaya ngokufumana umbane ongenanto ongenawo umgca wendlela ebanzi. I-router ithumela i-WiFi kwindlu yakho kunye neekhompyutha kunye nezixhobo zakho zingaxhunyiwe ngaphandle kwee-wire. Funda kabanzi kwiindawo zokuhlala ze-WiFi .
Iiprotoksi ze-WiFi - 802.11
I-WiFi ngokwenene ngumgaqo - nkqubo , owathi ngamagama amabini, uluhlu lwemiqathango elawula indlela ukudluliswa kwedatha kuqhutyelwa ngayo inethiwekhi, ukuze ufumane zonke iicomputer ezihambelana nokuhanjiswa. Igama lekhowudi linikezelwe yi-IEEE kwintsapho yezivumelwano apho i-WiFi ifumaneka yi-802.11. Eli nani lilandelwa yileta: a, b kunye ne-WiFi. I-802.11g yinguqulo entsha kunye engcono, kunye nesantya esiphezulu sesantya kunye nohlu olubanzi.
Okufunekayo kwi-WiFi
Awudingi ukukwazi ukuzuza kwi-WiFi. Kubiza kakhulu ukusetha umnatha, kungekhona ukuba kunzima, kodwa i-hardware iya kuba neendleko. Kodwa akungabi nantoni na ukuba ndibe ne-WiFi yam hotspot ekhaya, kuba ndifumene i-router yami engenazintambo kunye nenkonzo yam intanethi ye-intanethi.
Ngoku into oyifunayo iikhomputha kunye namacebo anikwe amandla e-WiFi. Kwimeko yeekhomputha kunye nee-laptops, kufuneka babe ne-adapter ye-WiFi okanye amakhadi. Xa uthenga i-laptop, qiniseka ukuba ubona i-WiFi okanye i-WLAN okanye i-802.11g kwiinkcukacha. Ukuba i-laptop yakho ayinayo loo nto, usenokuba ne-adapter ye-USB Wi-Fi. Kuyafana kwikhompyutha yakho yedeskithophu. Ngamafowuni, kufuneka baxhase ii-WiFi kunye ne-WiFi ifowuni zimbalwa kwaye zibiza kakhulu, nangona ziyaziwayo.
Emva koko uzakufuna isofthiwe. Kodwa oku akusiyo intlekele, ngokuba iifowuni ze-WiFi ziza kunye nenkxaso yesofthiwe kunye nazo zonke iinkqubo ezisebenzayo zekhomputha zekhomputha ziza ne-software eyakhelwe kwi-WiFi yoxhumo lwe-software. Kukho neqela leenkqubo ezikhululekile apho ukukhuphela, ukuba ufuna izicelo zesithathu kunye neziphambili ze-WiFi.
Indlela WiFi Inokuzuzisa ngayo
I-WiFi inokukunceda ngeendlela ezininzi:
- Inika ukuhamba. Ndifumana uxhumano lwe-intanethi ngaphandle kwentambo kwaye ndingakwazi ukuyenza ngaphandle kwikhompyutheni yam kwi-laptop ekhaya nasemsebenzini. Kungenxa yokuba ndinayo i-WiFi hotspots kokubili ekhaya nasemsebenzini. Ndiyakwazi ukudibaniswa ngaleyo ndlela naphi na indawo enye indawo ye-WiFi hotspot, njengomyezo wentpala kamasipala, umzekelo.
- Yindlela enhle yokuxhuma kwi-Intanethi ngeefowuni eziphathekayo kunye nee-PDA. Oku kuvula inani lamathuba abasebenzisi abasebenzisa i-intanethi, kubandakanya ukukhwela i-intanethi, ukudlala imidlalo, ukuthetha, njl.
- Iyenza i-LAN ibe yinto eguquguqukayo, inokutsha kwaye iguquguquke. Nayiphi na umatshini angaxhuma kwaye anqamle kwinethiwekhi nganoma naliphi ixesha.
- Ivumela indawo ezikude kwaye ngoko zithintela iintambo zonxibelelwano, njengeendawo zasemaphandleni emazweni asakhulayo, ukufumana inzuzo ekuxhumeni. Ezinye iinzame zifunwa ngabaqulunqi, kodwa oku kunokwenzeka kwiindawo ezininzi: umzekelo jonga inveneo.com, airjaldi.com, wndw.net
- Ikuvumela ukuba ulondoloze imali enkulu kwinxibelelwano ngefowuni yakho yeselula ngelixa ukwenza zombini iifowuni zendawo kunye namazwe ngamazwe, ngeVoIP. Funda ngezantsi.
I-WiFi kunye ne-Voice phezu kwe-IP - Ukugcina imali kwiNxibelelwano
I-Voice phezu kwe-IP , ngaphandle kweenzuzo zayo ezininzi, ivumela abantu ukuba banxibelelwano ngezwi ngenxa yexabiso elincinci xa bengenasikhulu. Ukusebenzisa iVoIP kunye nekhompyutheni yakho yeselula okanye ifowuni kwi-WiFi hotspot, unokwenza iifowuni zamahhala okanye ixabiso elincinci.
