Kwinkqubo yokuhanjiswa kwenethiwekhi, ukuba zonke ii-hubs zisetyenziswa.Kuqinisekile ukuba kwinkqubo yothumelo, ngenxa yokuba imiqondiso emininzi kufuneka isasazwe, i-domain yengxabano iya kuveliswa.Ngeli xesha, unxibelelwano phakathi kwemiqondiso luya kuphazamiseka kakhulu, kwaye izixhobo kwi-s...

Yintoni i-LAN?I-LAN ithetha Uthungelwano lweNdawo yeNgingqi.I-LAN imele i-domain yosasazo, okuthetha ukuba onke amalungu e-LAN aya kufumana iipakethi zosasazo ezithunyelwa naliphi na ilungu.Amalungu e-LAN anokuthetha omnye nomnye kwaye anokuseta iindlela zawo zeekhompyuter ezisuka kubasebenzisi abahlukeneyo ukuba bathethe nomntu ngamnye o...

Umaleko wekhonkco lwedatha ye-WLAN isetyenziswa njengomaleko ophambili wokuhanjiswa kwedatha.Ukuze uqonde i-WLAN, kufuneka uyazi ngokweenkcukacha.Ngokusebenzisa ezi ngcaciso zilandelayo: Kwi-protocol ye-IEEE 802.11, i-MAC sublayer yayo iqulethe iindlela zokufikelela kwimidiya ye-DCF kunye ne-PCF: Intsingiselo ye-DCF: Ukusabalalisa...

I-PHY, umaleko womzimba we-IEEE 802.11, unembali elandelayo yophuhliso lwetekhnoloji kunye nemigangatho yobugcisa: IEEE 802 (1997) Itekhnoloji yokumodareyitha: ukuhanjiswa kwe-infrared ye-FHSS kunye ne-DSSS Ibhendi yamaza okusebenza: esebenza kwi-2.4GHz frequency band (2.42.4835GHz, 83.5MHZ iyonke...

Kukho izibizo ezininzi ezibandakanyekayo kwi-WLAN.Ukuba ufuna ukuqonda ngokunzulu amanqaku olwazi lwe-WLAN, kufuneka wenze inkcazo epheleleyo yobungcali kwinqanaba ngalinye lolwazi ukuze ukwazi ukuqonda lo mxholo ngokulula ngakumbi kwixesha elizayo.Isitishi (STA, ngokufutshane).1).Isikhululo (inqaku), al...

I-WLAN inokuchazwa kuzo zombini ingqiqo ebanzi kunye nengqiqo emxinwa: Kwimbono encinci, sichaza kwaye sihlalutye i-WLAN kwiimvakalelo ezibanzi kunye nezimxinwa.Ngengqiqo ebanzi, i-WLAN yinethiwekhi eyenziwe ngokutshintshela enye okanye yonke imidiya yosasazo ye-LAN enentambo ngamaza erediyo, anje nge-infrared, l...
