Yazi imininingwane ngayinye mayelana ne- I-Red PanKulesi sihloko sizochaza umsebenzi waso obalulekile, uzomangala impela! Woza uzofunda nathi ngokuningiliziwe kokuthi yini lawa manethiwekhi asetshenziswayo nokuthi kungani esetshenziswa, akha enye yezinsimu ezinokuvela kobuchwepheshe okusheshayo.
IPan Red: Incazelo
Isakhiwo esinamaphethini esici sibizwa ngenethiwekhi. Leli gama livela kwelesiLatini elithi "rete" futhi lisetshenziswa emikhakheni ehlukahlukene, kepha kwikhompyutha, igama leqoqo lamakhompiyutha axhuma futhi abelane ngezinsiza livame kakhulu. Inethiwekhi ingahlukaniswa ngezindlela ezahlukahlukene ngokususelwa kububanzi benethiwekhi, ubudlelwane obusebenzayo bezinto, nendlela yokuxhuma. Umqondo wenethiwekhi ye-WAN uyingxenye yokuhlukaniswa kwenethiwekhi ngokususelwa kububanzi bayo.
Izingxenye zenethiwekhi ye-WAN ngamakhompyutha anikezelwe ekusebenziseni izinhlelo zomsebenzisi, ezibizwa ngokuthi ama-host. I-router ecacisa ukwahlukana phakathi kwemigqa yokudlulisela nezinto zokushintsha; kanye ne-subnet eyakhiwe ukuxhumana kwezingosi eziningi.
Ukusebenza kwala manethiwekhi kuklanyelwe ukusetshenziswa kwasekhaya kuphela, ngoba uhla lwamasiginali amafushane futhi ijubane alisheshi lapho amadivayisi amaningi exhunywe ngasikhathi sinye.
Amanye ala madivayisi angaxhunywa kubantu noma asetshenziswe njengezembatho (njengezinzwa). Ezinye zingalungiswa okwesikhashana noma zenziwe ngesikhala somuntu siqu (isb., Izinzwa, amaphrinta, nama-PDA).
Esikhathini sethu uxhumano olungenantambo luzuze intuthuko emangalisayo futhi lwenze intuthuko enkulu kule minyaka eyishumi edlule, kusobala. Izibonelo zokuqala ezizovela kulo mkhakha yi- "GSM, IS-95, GPRS ne-EDGE, UMTS ne-IMT-2000", okuwubuchwepheshe obusha obuvumela abantu ukuthi badlulise amafayela amaningi ngenethiwekhi engenantambo.
Amagama agqamile: inethiwekhi yendawo yomuntu siqu (PAN), ukukhonjwa kwezinsongo zokuphepha ezingenantambo, inethiwekhi yekhompyutha ye-PAN, ukumbozwa kwenethiwekhi ye-PAN, ibanga lenethiwekhi le-PAN.
Inethiwekhi yendawo yasendaweni (Lan)
Ngoba ingaxhuma inani elikhulu lamadivayisi futhi imboze nesakhiwo sonke ngaphandle komthungo, ingaba enye yamanethiwekhi asetshenziswa kakhulu ebhizinisini. Futhi, ukuhambisana kwayo kungcono kunenethiwekhi yakudala njengoba ikwazi ukuxhuma amakhompyutha, amaphrinta, ama-scanner, amakhophi kanye nanoma yimiphi imishini yesimanjemanje yensimbi.
Wi-Fi
Izinsimbi ezibizwa nge-Wi-Fi (amadivayisi ahambisana namazinga we-IEEE 802.11a, 802.11b, 802.11g kanye nama-802.11n) nawo angakha isisekelo se-PAN. I-Wi-Fi inikeza umkhawulokudonsa nobubanzi obukhulu kune-Bluetooth, kodwa isetshenziswa ngokuyinhloko ukunikeza ukufinyelela kunethiwekhi yendawo (i-LAN) noma inethiwekhi yendawo engenantambo (WAN). NgesiNgisi i-LAN engenantambo.
Ngakho-ke, noma abanye abasizi bomuntu siqu bedijithali namanye amadivayisi aphathekayo enamakhono we-Wi-Fi endaweni ye-PAN. I-Wi-Fi ngokuvamile ayibhekwa njengokuncintisana okuqonde ngqo kwi-Bluetooth.
Ukucabangela
Ngokungafani ne-LAN elungiselelwe endaweni eyodwa futhi engalokothi inyakaze, ngokuvamile isungulwa endaweni yokusebenza yabasebenzisi ngabodwana. Ibhamuza eliyindilinga elinobubanzi obungamamitha ayi-33 (amamitha ayi-10) lizungeze umsebenzisi namanye amadivayisi omuntu siqu. Ngakho-ke hamba uye endaweni ngomsebenzisi.
I-PAN ingahanjiswa kuphela ngemoto, isitimela, ulwandle noma umoya ekhaya lakho noma ehhovisi noma kwenye indawo, ngakho-ke ubuchwepheshe obusetshenziselwa ukudala i-PAN kumele buhlangabezane nezidingo ezithile maqondana nejubane lokudluliswa kwedatha, umkhawulokudonsa, amandla nokuphepha.
