Akukho nqongophala yabantu abanikela ngcebiso ukuze bancede bafundise abanye ngamanethiwekhi ekhompyutha. Ngesizathu esithile, nangona kunjalo, ezinye iinkcukacha malunga nokuthungatha i-intanethi zivakala ukungaqondwa, zidala ukudideka kunye nokucinga okungalunganga. Eli nqaku lichaza ezinye zeengcinga eziphosakeleyo.

IQINISO: IiNethwekhi zeeKhompyutha zisebenziseka nangaphandle kokungena kwi-Intanethi
Abanye abantu bacinga ukuba uxhulo lwe-intanethi lunengqiqo kulabo abaneenkonzo ze- intanethi . Nangona ukuxhuma i -intanethi kuxhomekeke kumanethiwekhi amaninzi asekhaya , akudingeki. Ukunxibelelana kweekhaya kusekela ukwabelana ngeefayile kunye nabashicileli, umculo womculo okanye ividiyo, okanye ukudlala phakathi kwezixhobo endlwini, bonke ngaphandle kokufikelela kwi-Intanethi. (Ngokucacileyo, ukukwazi ukufikelela kwi-intanethi kuphela kwengeza kwiinethiwekhi zentsebenzo kwaye kuya kuba nzima kwiintsapho ezininzi.

FALSE: I-Wi-Fi Ngaba Yona Mhlobo woNxibelelwano lwe-Wireless
Amagama athi "inethiwekhi engenazintambo" kunye "nenethiwekhi ye-Wi-Fi" ngamanye amaxesha asetyenziswa ngokungafaniyo. Zonke iinqununu ze-Wi-Fi zizintambo ezingenantambo, kodwa ezingenazintambo zibandakanya iintlobo zethungelwano ezakhiwe ngokusebenzisa ubuchwepheshe obufana neBluetooth . I-Wi-Fi ihlala yinto ekhethwa kakhulu kwiindawo zokunxibelelana zasekhaya, ngelixa iifowuni kunye nezinye izixhobo eziphathekayo zixhasa i-Bluetooth, i- LTE okanye abanye.

IZIMFU: IiFayile zokuTshintshela iiFayile kwiiNqanaba eziLungelelaniso zeBhanwidth
Kunengqiqo ukuthatha uxhulumaniso lwe-Wi-Fi olulinganiselwe kwi-54 Megabit yesibini (Mbps) lunakho ukudlulisela ifayile yobukhulu beemitha ezingama-54 kwisibini. Ngokwenza oko, ezininzi iintlobo zokunxibelelana kwenethiwekhi , kuquka i-Wi-Fi ne-Ethernet, ayenzi ndawo naphaya kweenombolo zamanani omda wokubala.
Ngaphandle kwedatha yefayili ngokwayo, amanethiwekhi kufuneka kwakhona axhase iimpawu ezifana nomyalezo wokulawula, iintloko zeepakethi kunye nezihlandlo ze-retransmissions zedatha, apho ngasinye singadla i-bandwidth ebalulekileyo. I-Wi-Fi iphinde isekele into ebizwa ngokuthi "ukutshintsha kwezinga lokutshintsha" elinciphisa ngokukhawuleza ukuxhuma kwe-intanethi ukuya kuma-50%, kwi-25% okanye nangaphantsi kobunzima obukhulu kwezinye iimeko. Ngenxa yezizathu, ii- Mbps ezingama-54 ze-Wi-Fi zidibanisa idatha yeefayile kumaxabiso angaphezulu kwe-10 Mbps. Ukudluliselwa kwedatha efanayo kwii-intanethi ze-Ethernet nazo zivame ukugijima kuma-50% okanye ngaphantsi kobuninzi babo.

IQINISO: Abantu ngabanye baya kulandelwa kwi-Intanethi yabo ye-IP
Nangona isixhobo somntu sinokunikezwa ngeso nasiphi na idilesi ye-intanethi ye-intanethi ye-Intanethi (IP) , iinkqubo ezisetyenziselwa ukwabela iidilesi ze-intanethi kwi-intanethi zibophelela kwindawo ethile kwindawo ethile. Ababoneleli ngeNkonzo ye-intanethi bafumana iibhloko zee- IP zamakheli kwi-body governing body (i-Intanethi inikezelwe ngamanqaku e-Intanethi-IANA) kwaye inikezela abathengi babo ngee dilesi ezivela kumachibi. Abaxhasi be-ISP kwisixeko esisodwa, umzekelo, ngokubanzi babelana ngesilwanyana samakheli kunye namanani alandelelanayo.
Ngaphezu koko, amaseva we-ISP agcina iinkcukacha zeengxelo zeengxelo zee-IP zabo zeemephu ezifakwe kumakhasimende athile ngabathengi. Xa i-Motion Picture Association yaseMelika ithatha izenzo ezithe zenziwa ngokusemthethweni kwi-intanethi yefayili kunye nefayili ekwabelana ngayo kwiminyaka edluleyo, zafumana ezi rekhodi kwi-ISP kwaye zaziyokwazi ukuhlawulisa ngabanikazi bezindlu ngabanye ngokuphulaphula ngokusekelwe kwidilesi ye-IP abo bathengi basebenzisa ixesha.
Olunye ubuchwepheshe njengamava- proxy angabonakali akhona ayenzelwe ukufihla ubunikazi bomntu kwi-intanethi ngokuthintela idilesi ye-IP ukuba ilandelwe, kodwa oku kunemiqathango.

I-FALSE: IiNethwekhi zaseKhaya kufuneka zibe nezona ziLuhlu oluLungileyo
Ukufaka i- router ebanzi kunciphisa inkqubo yokuseka inethwekhi yasekhaya . Amadivaysi angakwazi ukufikelela kule ndawo ephakathi ngokusebenzisa uxhumano lwe- wire kunye / okanye olungenantambo , ngokudala ngokuzenzekelayo inethiwekhi yendawo eyenza ukwabelana ngeefayile phakathi kwezixhobo. Ukufakela imodem ebanzi kwi-router kufanayo kwenza ukwabelana ngokuxhamla kwi-inthanethi ngokuzenzekelayo . Bonke abaqhubi banamhlanje baquka ukuxhaswa kwe- firewall inkxaso yokhuseleko ngokuzenzekelayo ikhusela zonke izixhobo ezixhunyiwe emva kwayo. Ekugqibeleni, ii-routers ezininzi ziquka iinketho ezongezelelweyo zokumisa nje ukwabelana ngeprinta, iifayile ze-IP (VoIP) , njalo njalo.
Yonke le mi sebenzi inokuthi iyenze ngaphandle kwe-router. Iikhompyutyana ezimbini ziyakunxibelelaniswa ngokuthe ngqo ngokuxhomekeke koontanga, okanye enye ikhompyutha ingachongwa njengendlela yesango lekhaya kwaye ilungiselelwe nge-intanethi kunye namanye amashishini okwabelwana ngolwazi ngamanye amacebo amaninzi. Nangona ii-routers ngokucacileyo ixesha lokusindisa kunye nokulula kakhulu ukugcina, ukusetyelwa kwe-router-less kungasebenza nakakhulu kwiinkonzo ezincinci kunye / okanye zesikhashana.
