Akukho ukusweleka kwabantu abanikeza iseluleko ukusiza abanye ukufundisa abanye ngamanethiwekhi ekhompyutha. Nokho, ngesinye isizathu, amaqiniso athile mayelana nokuxhumana ngokuvamile ahlukumezwa, adala ukudideka nokucabanga okungalungile. Lesi sihloko sichaza ezinye zalezi zinkolelo ezingavamile.

IQINISO: Ama-Network Networks Asebenza Ngisho Ngaphandle Kokufinyelela kwe-inthanethi
Abanye abantu bacabanga ukuthi ukuxhumana kunengqondo kulabo abanesevisi ye- intanethi . Nakuba ukuxhuma uxhumano lwe-intanethi kuyinto evamile kumanethiwekhi amaningi ekhaya , akudingeki. Ukuxhumana kwekhaya kusekela ukwabelana ngamafayela namaphrinta, ukusakaza umculo noma ividiyo, noma ngisho nokudlala phakathi kwamadivaysi endlini, bonke ngaphandle kokufinyelela kwe-inthanethi. (Ngokusobala, ikhono lokuthola intanethi lanezela kuphela amandla okuxhumana nenethiwekhi futhi ngokuya kuba yindingo yemindeni eminingi.)

FALSE: I-Wi-Fi Yona Mhlobo Owodwa Wama-Networking Wireless
Amagama athi "inethiwekhi engenantambo" nethi "inethiwekhi ye-Wi-Fi" ngezinye izikhathi isetshenziswe ngokungafani. Wonke amanethiwekhi we-Wi-Fi ayenawo ama-wireless, kodwa ama-wireless ahlanganisa nezinhlobo zamanethiwekhi ezakhelwe ngokusebenzisa ubuchwepheshe obufana ne- Bluetooth . I-Wi-Fi ihlala yiyona ethandwa kakhulu kunethiwekhi ye-intanethi, kuyilapho amaselula namanye amadivayisi weselula nawo asekela i-Bluetooth, i- LTE noma abanye.

FALSE: Amafayela Wokudlulisa Amanethiwekhi Emikhawulweni Yezintambo Zokulinganiswa Zabo
Kunengqondo ukuthatha uxhumano lwe-Wi-Fi olulinganisiwe ku-54 Megabit ngesigamu (Mbps) lungakwazi ukudlulisa ifayela lobukhulu bamakhilogremu 54 ngomzuzwana owodwa. Ngokwenza, izinhlobo eziningi zokuxhumeka kwenethiwekhi , kufaka phakathi i-Wi-Fi ne-Ethernet, azenzi noma kuphi eduze nezinombolo zabo ezilinganisiwe zomkhawulokudonsa .
Ngaphandle kwedatha yefayela ngokwayo, amanethiwekhi nawo kufanele asekele izici ezifana nokulawula imiyalezo, izinhloko zepakethe kanye nama-retransmissions wedatha, okunye okungawudla umkhawulokudonsa obalulekile. I-Wi-Fi ibuye isekele isici esibizwa ngokuthi "ukuguquguquka kwezinga elishintshayo" okunciphisa ngokuzenzekelayo ukuvinjelwa kokuxhumeka kufika ku-50%, 25% noma ngaphansi kwesilinganiso esiphezulu kwezinye izimo. Ngenxa yalezi zizathu, ama-54 Mbps uxhumano lwe-Wi-Fi ngokuvamile lidlulisela idatha yefayela kumazinga angaphezulu kwe-10 Mbps. Ukudluliselwa kwedatha okufanayo kumanethiwekhi e-Ethernet nakho kuvame ukugijima ku-50% noma ngaphansi kokuphezulu kwawo.

IQINISO: Abantu bangabhekwa ku-inthanethi ngekheli labo le-IP
Nakuba idivayisi yomuntu ingachazwa noma iyiphi ikheli le- Intanethi ye-Intanethi ye-Intanethi (IP) , amasistimu asetshenziselwa ukwabela amakheli e-intanethi ku-intanethi awabopha endaweni ethile endaweni ethile. Abahlinzeki Besevisi Ye-intanethi (i-ISPs) bathola amabhulogi amakheli e- IP avela enhlanganweni ebusayo ye-intanethi (i-Intanethi Yanikezwe Amanani Agunyaziwe - IANA) futhi inikeze amakhasimende abo ngamakheli avela kulawa manzi. Amakhasimende we-ISP edolobheni elilodwa, isibonelo, ngokuvamile abelana ngamachibi amakheli anezinombolo ezilandelanayo.
Ngaphezu kwalokho, amaseva we-ISP agcina amarekhodi eningi okuningiliziwe wezabelo zabo zekheli le-IP ezifakwe kumakhasimende ngabanye amakhasimende. Lapho i-Motion Picture Association yaseMelika ithatha izinyathelo zomthetho eziqhamuka ekuhlanganyeleni ifayela le-intanethi ye-peer-to-peer eminyakeni edlule, zathola la marekhodi avela ku-ISPs futhi zakwazi ukukhokhisa abanini bezindlu ngabanye ngokuphulwa okuqondile okusekelwe ekhelini le-IP labo amakhasimende abasebenzisa isikhathi.
Ezinye ubuchwepheshe ezifana namaseva e-proxy angaziwa akhona aklanyelwe ukufihla ubunikazi bomuntu nge-intanethi ngokuvimbela ikheli le-IP ukuthi lingalandelwa, kodwa lokhu kuneminye imikhawulo.

FALSE: Amanethiwekhi Ekhaya Kufanele Abe Ne-Red Router eyodwa
Ukufaka i- router broadband kwenza kube nenqubo yokusetha inethiwekhi yendlu . Amadivaysi angakwazi ukungena kule ndawo eyinhloko ngokusebenzisa uxhumano oluxhunyiwe noma / noma olungenantambo , ngokudala ngokuzenzakalelayo inethiwekhi yendawo eyenza ukwabelana kwamafayela phakathi kwamadivayisi. Ukuxhuma i- modem ebanzi yokubandlulisela ku-router nakho kwenza ukwabelana ngokuxhumeka kwe-Intanethi okuzenzakalelayo . Wonke ama-routers wanamuhla afaka phakathi ukwesekwa kwe- firewall yenethiwekhi eyakhelwe ngaphakathi okuvikela ngokuzenzakalelayo wonke amadivayisi axhunyiwe ngemuva kwawo. Okokugcina, ama-routers amaningi afaka phakathi izinketho ezengeziwe zokumane uhlele ukwabelana kwephrinta , izinhlelo zezwi ze-IP (VoIP) , njalo njalo.
Yonke yale misebenzi efanayo ingafezwa ngokuqondile ngaphandle komzila. Amakhompiyutha amabili angaxhunyaniswa ngokuqondile njengomxhumanisi ohambisana nontanga, noma ikhompyutha eyodwa ingahle ibekwe njengesango lendlu futhi ilungiswe nge-Intanethi namanye amakhono wokwabelana ngezibonelelo kwamanye amadivaysi amaningi. Yize ukuthi ama-routers ngokusobala amahora asindisa futhi alula kakhulu ukulondoloza, ukusethwa kabusha okungahleliwe kungasebenza futhi ikakhulukazi kumanethiwekhi amancane kanye / noma okwesikhashana.
