Wireless: lokho kuba ubuchwepheshe bama-computer?

Muva nje, umbuzo kwande phakathi abasebenzisi computer ezikhumulweni, laptops noma idivayisi yeselula: "Wireless - kuyini?". Ake sibheke lesi sihloko futhi unike izincazelo ezithile eziyisisekelo.

Wireless: kuba ngomqondo ovamile?

Push off ukuqala kuzosuka izincazelo futhi ukuhumusha amagama esuka esiNgisini. Kumiswa It is kusukela izwi wire (ikhebula, intambo, wire) kanye Ukuvalwa -less, okuyinto lapho ukungezwa izwi yokuqala "ukungabi", "khulula" futhi t. D.

Empeleni, yingakho-ke kungenziwa baphetha ngokuthi engenantambo, eqinisweni, kusho "engenantambo." Namhlanje into enjalo isikhathi eside osebenza ku izinhlelo zokuxhumana kanye ne-Inthanethi. Ongazange wezwa-Wi-Fi? Kodwa lenethiwekhi kungenziwa libhekene ngokunembile ukuthi ngaleli gama elithi "okungenantambo".

Kuyini adaptha Wireless: imiqondo eyisisekelo nezinhlobo

Ngokuphathelene adapters ezisetshenziswa imishini yezokuxhumana engenazo izintambo, ezivame kakhulu yiwona imizila, ADSL-modems nge edidiyele -Wi-Fi, i-USB adaptha, kanye izingxenye okujwayelekile ngokusekelwe PCI ibhasi efakiwe, isb, amakhompyutha umile, Wi-Fi -modules e amagajethi mobile, kanye ukuxhumana kusho nge-Bluetooth (nabo basonta engenantambo isigaba ubuchwepheshe).

Nakanjani ukuthi izimiso wokusebenza wabo athé ukwehluka, kanye ukufakwa kanye ukucushwa izindlela. Ngokwesibonelo, i-router, kuye ngokuthi model, anganikeza ukusatshalaliswa IP amakheli kumadivaysi amaningi, futhi uhla amabanga of 10-100 m wohlu emehlweni. USB-adaptha kanye namadivayisi umile ke esekelwe PCI ibhasi exhunywe ngqo kumakhompyutha noma laptops futhi akwazi ukuxhumana okungenantambo kuphela ezikhumulweni okuyinto ihlobene ngokuqondile. Njengoba kucacile kakade mayelana isenzo noma ukutholakala isiginali namanye amadivayisi ayikwazi ukukhuluma lapha. Nakuba nabanye onobuhle ungakwazi ukwenza ukusatshalaliswa kusuka kwikhompyutha yakho siqu noma laptop. Kodwa umbuzo thina ningathinti.

Amanethiwekhi anganantambo futhi imali eyengeziwe

Umqondo "wireless inethiwekhi» (Wireless Network) esanda kutholakala. Uma sikhuluma ubuchwepheshe bama-computer, kukhona izigaba ezimbili eziyinhloko amanethiwekhi bungabonakala: Wi-Fi we-WiMAX.

Nakanjani ukuthi uma ufaka ukuxhumana kumanethiwekhi ezifana sisebenzisa ubuchwepheshe ezahlukene. Ngokuvamile, amanethiwekhi e-Wi-Fi basebentise okuthiwa amaza ezingekho emthethweni kanye okunomkhawulo engaba Ukusabalala, ngokuvamile ayidluli kwengu-100 m. Yiqiniso, okuningi kuncike umthamo imishini nomthengisi, isibonelo, umkhiqizo we-router.

Kunenye umqondo wireless. Kuyini ngokuya kumanethiwekhi e-WiMAX? Lokhu, ngaphezu kwakho konke, ukusetshenziswa ilayisensi isignali ukudluliswa imvamisa futhi amashumi esehlanganise amakhilomitha. Nokho, phakathi abasebenzisi akuxhomekile abavamile enjalo sokusakaza ekhethekile abakutholanga nje ngenxa yezindleko zayo okusezingeni eliphezulu (okusho imishini, ukufakwa, ukugcinwa, izimali yomsebenzisi, nokunye. D.).

Uma ucabangela isihloko «Wireless :? Yini kuba" Asikwazi ukushalazela izindlela Bluetooth ukudluliswa kwedatha wireless. Yiqiniso, ezimweni eziningi, ukufinyelela ku-intanethi amamojuli enjalo ayifanele, kodwa ukudluliswa okusheshayo amafayela nedatha kungahlali kahle kakhulu. Yiqiniso, kuyafaneleka ukucabangela nokukhawulela engaba isinyathelo, ngokuvamile ayeqi kwamamitha ayi-10.

isiphetho

Nasi emfushane ukuthi kuyinto zokuxhumana ezingenazo izintambo ubuchwepheshe. Kulokhu, siye sacabangela kuphela izwe ikhompyutha, kodwa ambalwa cabanga yokuthi omakhalekhukhwini ngokuyisisekelo iyafana kusebenza kulokho okuvame ukubizwa ngokuthi ubuchwepheshe obungenawaya be. Ngisho ekuphileni kwansuku zonke sibhekana nazo cishe zonke izinsuku. Thatha okungenani ezejwayelekile elawulwa kude ekhaya Imishini elawulwa kude. Isebenzisa kungenzeka ngokudlulisela nokwamukela ukulawula isignali esekelwe amakhono ka isikhala seso lefoni. Nokho, ungaqhubeka kulolu hlu isikhathi eside impela.
