Konke okudingeka ukwazi mayelana ne-LAN engenantambo evamile kakhulu
I-WiFi (futhi i-Wi-Fi ebhaliwe) imelela ukuthembeka kwe-Wireless. Kuyinto yobuchwepheshe benethiwekhi engenawaya evumela ukuthi amakhompyutha namanye amadivaysi axhumeke komunye nomunye abe yi-LAN kanye ne-intanethi ngaphandle kwezintambo nezintambo. I-WiFi ibizwa nangokuthi i-WLAN, emele i-wireless LAN, no-802.11, okuyinto ikhodi lobuchwepheshe ye-protocol.
Kulesi sihloko, sibheka i-WiFi kule migqa elandelayo:
- Ukufaneleka kwe-WiFi nokulinganiselwa
- I-WiFi Hotspots
- I-WiFi Protocol
- Izinsiza ze-WiFi
- Indlela i-WiFi engakuzuzisa ngayo
- I-WiFi nezwi nge-IP - Ukulondoloza imali ku-Communication
Ukufaneleka kwe-WiFi nokulinganiselwa
I-WiFi inikeza amandla amakhulu okuxhumana futhi ivuselele ama-LAN emhlabeni jikelele. Ngenxa ye-WiFi, abantu abaningi futhi bayakwazi ukuxhuma kwi-Inthanethi futhi kalula. Inzuzo enkulu kunazo zonke ze-WiFi yikuphatheka okunikezwa kubantu abasebenzisa amakhompyutha ephathekayo kanye namadivaysi ephathekayo afana namafoni smart kanye nama-PDA - angashintsha kusuka kunethiwekhi eyodwa kuya komunye ngaphandle kokuhlupheka kokukhathazeka ngezintambo.
I-WiFi inomkhawulo owodwa kakhulu, futhi yiyona kuphela imingcele enkulu enayo. Ngenxa yokuthi ubuchwepheshe be- LAN , i-WiFi inikeza indawo yokuxhumeka kwezinyawo eziningi kuphela. Ngaphandle kwamamitha angu-20-25, uvele ungaphandle kwenethiwekhi. I-antenna ye-WiFi ithumela amagagasi kuyo yonke indawo kuyo yonke indawo. Izimpawu ze-WiFi zilahlekelwa amandla njengoba zihamba phambili kude ne-antenna, yingakho ikhwalithi yokuxhumeka iyancipha njengoba ikhompyutha noma idivaysi ibekwe kude nomthombo. Izinhlelo zokusebenza zokuphatha uxhumano lwe-WiFi kuma-computer nakwamanye amadivayisi ngokuvamile ziba namazinga okufaka amandla okuxhumana: okuhle kakhulu, okuhle, ompofu njll.
I-WiFi Hotspots
I- hotspot ye-WiFi yindawo eseduze nomthombo we-WiFi (i-router engenantambo, i-antenna ye-WiFi, njll, okwenza izibonakaliso ze-WiFi) lapho amakhompyutha namadivayisi angakwazi ukuxhuma nge-WiFi. Ama-Hotspots angatholakala ezindaweni eziningi: kuma-campuses, emahhovisi, emahhafini, ngisho nasekhaya. Isibonelo, ungaba ne-WiFi hotspot ekhaya ngokuba nomzila ongenazintambo nomugqa wakho we-broadband. I-router ithumela i-WiFi kuyo yonke indlu yakho namakhompyutha akho namadivayisi angaxhunyiwe ngaphandle kwezintambo. Funda kabanzi kuma- hotspots e- WiFi .
Izivumelwano ze-WiFi - 802.11
I-WiFi empeleni iprotocol , okusho ngamagama amabili, uchungechunge lwemithetho elawula indlela ukudluliswa kwedatha kwenziwa ngayo inethiwekhi, ukuze uthole yonke imishini ehambisana nokudluliselwa. Igama lekhodi elihlinzekwe i-IEEE emndenini wezinhlelo lapho i-WiFi itholakele khona ngu-802.11. Le namba ivame ukulandelwa yincwadi: a, b no-g yi-WiFi. I-802.11g inguqulo entsha futhi engcono, enejubane lokudlulisela eliphakeme nobubanzi obubanzi.
Okudingayo nge-WiFi
Awudingi okuningi ukuze ukwazi ukuzuza ku-WiFi. Kubiza kakhulu ukusetha inethiwekhi, hhayi ukuthi kuyinkimbinkimbi, kodwa i-hardware izobiza kancane. Kodwa akungidli lutho lokuba ne-WiFi yami hotspot ekhaya, ngoba ngithole i-router yami engenazintambo ngenkonzo yami ye-intanethi ye-broadband.
Manje okudingayo yi-computer namadivayisi anikwe amandla we-WiFi. Endabeni yamakhompyutha nama-laptops, kudingeka abe nama-adapter noma amakhadi we-WiFi. Uma uthenga i-laptop, qiniseka ukuthi ubona i-WiFi noma i-WLAN noma i-802.11g ekuchazeni. Uma i-laptop yakho ingenalo, ungasenayo i-adapter ye-USB Wi-Fi. Same isebenza kukhompyutha yakho yedeskithophu. Ngamafoni, kufanele asekele ama-WiFi namafoni we-WiFi ambalwa kakhulu futhi abiza kakhulu, nakuba athandwa kakhulu.
Khona-ke uzodinga isofthiwe. Kodwa lokhu akusona ukuhlukunyezwa, ngoba amafoni we-WiFi ahambisana nokusekelwa kwesofthiwe futhi wonke amasistimu asebenzayo ekhompyutheni ayenayo isofthiwe yokuphatha uxhumano lwe-WiFi. Kukhona futhi izinhlelo eziningi zamahhala ngaphandle kwalokhu okulanda ukulanda, uma ufuna izinhlelo zokusebenza zangaphandle nezithuthukisiwe zokuphathwa kwe-WiFi.
Indlela i-WiFi engakuzuzisa ngayo
I-WiFi ingakuzuzisa ngezindlela eziningi:
- Inikeza ukuhamba. Ngithola i-intanethi ingaxhunyiwe ngaphandle kwekhompyutheni yekhompyutha yami ekhaya nasemsebenzini. Lokhu kungenxa yokuthi nginama-Wi-Fi hotspots kokubili ekhaya nasemsebenzini. Ngingaxhumeka ngaleyo ndlela noma yikuphi lapho kukhona i-hotspot ye-WiFi, njengengadini yasemasimini, isibonelo.
- Kuyindlela enhle yokuxhuma kwi-inthanethi ngamafoni omakhalekhukhwini nezi PDA. Lokhu kuvula amathuba amaningi kubasebenzisi baselula, kufaka phakathi ukuvula i-intanethi, ukudlala imidlalo, ukuxhumana, njll.
- Yenza i-LAN ibe nezimo eziguquguqukayo kakhulu, ezinamandla futhi ezinamandla. Noma imuphi umshini ungaxhuma futhi unqamule kwinethiwekhi noma kunini.
- Ivumela izindawo ezikude futhi ngaleyo ndlela zithathwe izintambo zokuxhumana, njengezindawo ezisemaphandleni emazweni asathuthuka, ukuze zizuze ekuxhumaneni. Iminye imizamo eminingi iyadingeka ngabakhi, kepha lokhu kungenzeka ezindaweni eziningi: isib ubone inveneo.com, airjaldi.com, wndw.net
- Ikuvumela ukuba usindise imali eningi ekukhulumisaneni ngokusebenzisa idivayisi yakho yeselula ngenkathi wenza kokubili izingcingo zendawo nezamazwe ngamazwe, nge-VoIP. Funda ngezansi.
I-WiFi nezwi nge-IP - Ukulondoloza imali ku-Communication
I-Voice over IP , ngaphandle kwezinzuzo zayo eziningi, ivumela abantu ukuba baxoxe ngezwi ngokushibhile kakhulu uma bengenasikhulu. Ukusebenzisa i-VoIP ngekhompyutha yakho yeselula noma idivaysi ku-Wi-Fi hotspot, ungenza amakholi wamahhala noma aphansi.
