I-PAN kunye nee-WPAN zidibanisa nezoBuntu, amaCandelo asondele
Inethwekhi yommandla womntu (PAN) yinkqubo yekhompyutheni ehlelwe kumntu ngamnye, kwaye isetyenziselwe ukusetyenziswa komntu kuphela. Ngokuqhelekileyo ziquka ikhompyutha, ifowuni, umshicileli, ithebhulethi kunye / okanye esinye isixhobo somntu siqu njenge PDA.
Isizathu sokuba ii-PAN zihlukaniswe ngaphandle kwezinye iintlobo zenethiwekhi ezifana nee-LAN , i- WLAN , i- WANs kunye ne-MANs kuba ingcamango yokuthumela ulwazi phakathi kwezixhobo ezikufuphi endaweni yokuthumela loo datha efanelekileyo kwi-LAN okanye kwi-WAN ngaphambi kokuba ifinyelele into esele iphakathi fi kelele.
Ungasebenzisa la manxeba ukuthumela ifayile kuquka i-imeyile, ukuqeshwa kwekhalenda, iifoto kunye nomculo. Ukuba ukutshintshwa kwenzelwa kwinethiwekhi engena-wireless, kuthiwa yi-WPAN, eyinkqubo yomnatha womntu ongenawo ucingo.
I-Technologies ezisetyenziselwa ukwakha i-PAN
Iinqununu zommandla zomntu zingabanamathengi okanye zingakhiwe ngeetambo. I-USB ne- FireWire zihlala zidibanisa i-PAN ene-WAN, ngelixa i-WPAN isebenzisa i- Bluetooth (kwaye ibizwa ngokuba yi-piconets) okanye ngezinye izixhobo .
Nasi umzekelo: Ikhowudi yeBluetooth ixhuma kwi-tablet ukuze ilawulwe isikhombimsebenzisi esakwazi ukufikelela kwisibhakabhaka sokukhanya esiseduze.
Kwakhona, umshicileli kwiofisi encinane okanye ikhaya elidibanisa kwideskithophu eziseduze, i-laptop okanye ifowuni ithathwa njengokuba ikhona kwi-PAN. Kuyafana neefowuni kunye nezinye izixhobo ezisebenzisa i-IrDA (i-Infrared Data Association).
Iingqinisiso, i-PAN ingaphinda iquke neenkcukacha ezincinci, ezinxibekayo okanye ezifakiwe ezingakwazi ukunxibelelana nokuqhagamshelana okufutshane kunye nezinye iifowuni ezingenantambo. I-chip efakwe phantsi kwesikhumba somnwe, umzekelo, ongagcina idatha yakho yezokwelapha, unako ukudibanisa nesazisi ukuhambisa ulwazi lwakho kugqirha.
Ubunzima Kangakanani IPAN?
Ii-network zangasese ezingenazintlu ngokubanzi zihlanganisa uluhlu lwama-centimeter ambalwa ukuya kwii-10 mitha (33 iinyawo). Ezi ntanethi zingabonwa njengoluhlobo olukhethekileyo (okanye i-subset) yamanethiwekhi asekuhlaleni axhasa umntu omnye endaweni yeqela.
Ulwalamano lwezixhobo zekhoboka lunokuthi lwenzeke kwi-PAN apho inamba yezixhobo zidibanisa kwisixhobo "esikhulu" esibizwa ngokuba yinkosi. Amakhoboka adlulisa idatha ngokusebenzisa idilesi yesixhobo. NgeBluetooth, ukuseta okunjalo kunokuba kukukhulu njengeemitha ezili-100 (330).
Nangona i-PAN ikhona, ngokucacileyo, ngokwabo, bayakwazi ukufikelela kwi-intanethi phantsi kweemeko ezithile. Umzekelo, ifowuni ngaphakathi kwe-PAN ingaxhunyezwa kwi-LAN enokufikelela kwi-intanethi, eyi-WAN. Ngokweendlela, uhlobo lothungelwano ngalunye luncinci kunomnye, kodwa zonke ziyakunxibelelana ngokuthe ngqo.
Iinzuzo zomNxibelelwano wendawo yoMntu
I-PAN yinto yokusebenzisa, ngoko ke iingeniso zingase ziqondwe kangangoko kunokuba xa uthetha ngamanethiwekhi amaninzi, umzekelo, uchaza intanethi. Ngomnatha wommandla womntu, izixhobo zakho zobuqu ziyakwazi ukudibanisa ukuxhumana ngokulula.
Ngokomzekelo, igumbi lokuhlinzwa esibhedlele linokuba ne-PAN yalo iphakanyiswe ukwenzela ukuba ugqirha unxibelelwano namanye amalungu eqela kwigumbi. Akukho mfuneko yokuba zonke iinkonzo zabo zokunxibelelana zidliwe ngethungelwano elikhulu kunokuba zifunyenwe ngabantu ziintsuku ezimbalwa. I-PAN iyakhathalela oku ngokusebenzisa uxhulumaniso lwexesha elifutshane njengeBluetooth.
Omnye umzekelo ukhankanywe apha ngasentla unombhobho ongenawucingo okanye ngisho nemouse. Akudingeki ukuba basebenzise iikhomputha kwezinye izakhiwo okanye izixeko, ngoko ke zakhiwe ukuba zixubane kunye nelokufuphi, ngokuqhelekileyo isisombululo sokubona umgca njengekhompyutha okanye ithebhulethi.
Ekubeni amacebo amaninzi axhasa uxhulumaniso lwee-short-range angakhusela uxhulumaniso olungagunyazisiwe ngaphambili, i-WPAN ithathwa njengenethiwekhi ekhuselekileyo. Nangona kunjalo, njenge-WLAN kunye nezinye iintlobo zenethiwekhi, inethwekhi yendawo yomntu ifikeleleka kalula kwi-hackers eseduze.
