Isendlalelo sesixhumanisi sedatha se-WLAN sisetshenziswa njengesendlalelo esiyinhloko sokudluliswa kwedatha. Ukuze uqonde i-WLAN, udinga futhi ukuyazi ngokuningiliziwe. Ngezincazelo ezilandelayo: Kumthetho olandelwayo we-IEEE 802.11, isisekelo saso se-MAC siqukethe izindlela zokufinyelela kwabezindaba ze-DCF ne-PCF: Incazelo ye-DCF: Sabalalisa...

I-PHY, isendlalelo esibonakalayo se-IEEE 802.11, inomlando olandelayo wokuthuthukiswa kobuchwepheshe kanye namazinga obuchwepheshe: IEEE 802 (1997) Ubuchwepheshe bemodulation: ukudluliselwa kwe-infrared ye-FHSS ne-DSSS Operating frequency band: esebenza ku-2.4GHz frequency band (2.42.4835GHz, 83.5MHZ isiyonke...

Kunamabizo amaningi abandakanyeka ku-WLAN. Uma udinga ukuqonda ngokujulile amaphuzu olwazi e-WLAN, udinga ukwenza incazelo egcwele yobungcweti yephuzu ngalinye lolwazi ukuze uqonde lokhu okuqukethwe kalula kakhudlwana esikhathini esizayo. Isiteshi (i-STA, ngamafuphi). 1). Isiteshi (iphuzu), al...

I-WLAN ingachazwa kokubili ngomqondo obanzi nangomqondo omncane: Ngokombono omncane, sichaza futhi sihlaziye i-WLAN ngazo zombili izinzwa ezibanzi neziwumngcingo. Ngomqondo obanzi, i-WLAN iyinethiwekhi eyenziwe ngokufaka enye noma yonke imidiya yokudlulisa ye-LAN enezintambo ngamaza omsakazo, njenge-infrared, l...

Ukuqonda ukuxhumana kwedatha kunethiwekhi kuyinkimbinkimbi. Kulesi sihloko ngizobonisa kalula ukuthi amakhompiyutha amabili axhumana kanjani, adlulise futhi athole ulwazi lwedatha futhi nephrothokholi ye-Tcp/IP yesendlalelo ezinhlanu. Kuyini ukuxhumana kwedatha? Igama elithi "ukuxhumana kwedatha" i...

Amaswishi aphethwe aphakeme kunalawo angaphethwe ngokwemibandela yokusebenza, kodwa adinga ubuchwepheshe bomlawuli noma unjiniyela ukuze abone amandla azo ngokugcwele. Ukuphathwa okunembe kakhudlwana kwamanethiwekhi nozimele bedatha yawo kwenziwa kwenzeke ngokusebenzisa iswishi ephethwe. Ngokolunye uhlangothi, ...
