Ukubuka ukuthi yiziphi izintambo ze-ethernet ezisethiwe kumanethiwekhi wired
Ikhebula le- Ethernet lingenye yefomu ethandwa kakhulu kwekhebula lenethiwekhi elisetshenziselwa amanethiwekhi wired. Amakhodi e-Ethernet axhuma amadivaysi ndawonye ngaphakathi kwenethiwekhi yendawo , njengama-PC, ama-routers , nokushintsha .
Ngenxa yokuthi lezi zingcingo zenyama, zinokulinganiselwa kwazo, kokubili ebangeni ukuthi zingakwazi ukwelula futhi zithwale izimpawu ezifanele, nokuhlala kwazo. Lesi sizathu esisodwa kunezinhlobo ezahlukene zezintambo ze-Ethernet; ukwenza imisebenzi ethile ezimweni ezithile.
Yeka ikhebula le-Ethernet elibukeka sengathi
Kukhona isithombe sekhebula elincane le-Ethernet eliphela kuleli khasi. Ifana nekhebula lefoni kepha likhulu futhi linamathenda amaningi.
Zombili izintambo zinejamo elifanayo ne-plug kodwa ikhebula le-Ethernet linezintambo eziyisishiyagalombili kanye ne-plug ekulu kunezingcingo ezine ezitholakala ezincingo zefoni.
Izinkambo ze-Ethernet, Yebo, zixhuma emachwebeni e- Ethernet , futhi futhi, zikhulu kunezingcingo zekhebula zefoni. I-Ethernet port ekhompyutheni ifinyeleleka ngekhadi le-Ethernet ebhodini le- motherboard .
Izintambo ze-Ethernet zivela ngemibala ehlukene kodwa izintambo zefoni ngokuvamile zivuthiwe.
Izinhlobo zezintambo ze-Ethernet
Izintambo ze-Ethernet zivame ukusekela amazinga omkhakha owodwa noma ngaphezulu kufaka Isigaba 5 (CAT5) no- Category 6 (CAT6) .
Ikhebula le-crossover uhlobo olukhethekile lwekhebula le-Ethernet elenzelwe ukuxhuma amakhompyutha amabili komunye nomunye. Ngokuphambene, izintambo eziningi ze-Ethernet zenzelwe ukuxhuma ikhompyutha eyodwa kum router noma ukushintsha.
Izintambo ze-Ethernet zenziwe ngokomzimba ngezindlela ezimbili eziyisisekelo ezibizwa ngokuthi ziqinile futhi zinezinhlanzi .
Amakhodi e-Ethernet aqinile anika ukusebenza okuncane kangcono nokuvikelwa okuthuthukisiwe ngokumelene nokuphazamiseka kagesi. Zibuye zisetshenziswe kaningi kumanethiwekhi ebhizinisi , i-wiring ngaphakathi kwezindonga zehhovisi, noma ngaphansi kwelabhu phansi kuya ezindaweni ezihleliwe
Izintambo ze-Ethernet ezinamandla azijwayele ukucubungula nokuphuka ngokomzimba, okwenza kube ngokufanelekile kwabahambi noma ezisekelweni zokuxhumana zenethiwekhi.
Ukulinganiselwa kwezingcingo ze-Ethernet
Ikhebuli elilodwa le-Ethernet, njengekhamera yamandla kagesi, linomkhawulo olinganiselwe wokubamba ibanga, okusho ukuthi banomkhawulo ongaphezulu ukuthi bangaba khona isikhathi eside ngaphambi kokuba ukulahlekelwa kwesignali (okubizwa ngokuthi ukulingwa ) kwenzeka. Lokhu kungenxa yezici zabo zokudlulisa kagesi futhi kuthinteka ngokuqondile ukuphazamiseka okuzungeze ikhebula.
Zombili iziphetho zekhebula kumele zibe eseduze kakhulu komunye nomunye ukuze zithole izimpawu masinyane, kodwa kude ngokwanele ezingxenyeni zikagesi ukugwema ukuphazamiseka. Noma kunjalo, lokhu kuphela akukhawuli usayizi wenethiwekhi ngoba i-hardware njengama-routers noma ama-hubs angasetshenziswa ukujoyina izintambo eziningi ze-Ethernet ndawonye kwinethiwekhi efanayo. Leli banga phakathi kwamadivayisi amabili libizwa ngokuthi ububanzi benethiwekhi .
Ubude obuningi bekhebula elilodwa le-CAT5, ngaphambi kokulinda, liyizinyawo ezingu-324. I-CAT6 ingakwazi ukukhuphukela ku-700 ububanzi. Khumbula ukuthi izintambo ze-Ethernet zingase zibe zide kodwa zingase zihlupheke ngokulahlekelwa kwesignali, ikakhulu uma kunezinye izinto zikagesi ezidlula ikhebula.
Qaphela: ubude bekhebula le-Ethernet buhlukile kancane uma ukhuluma ngezinsimbi ezincane, eziyisisekelo eziyishumi ezimbili, noma ezincane eziyishumi eziyisithupha. Okokuqala akufanele kube khona ngaphezu kwamamitha angu-600 ngenkathi ikhebula le-cable elilandelayo kufanele lifinyelele ubude bezingalo ezingamamitha angu-1,640.
Futhi cabanga ukuthi ikhebula elifushane lingase lihlupheke ngokucabanga. Kodwa-ke, abanye abasebenzisi baye babika akukho izinkinga ngamakhamera wekhebula njengezinga eliphansi ngisho namasentimitha angu-4.
Izinhlobo eziningana ezihlukahlukene ze- RJ-45 zikhona. Uhlobo olulodwa, oluhlelwe ukuthi lusetshenziswe ngezintambo ezifakwe emaceleni, ngokuvamile aluhambisani nezintambo eziqinile. Ezinye izinhlobo zezixhumi ze-RJ-45 zingase zisebenze nazo zombili izintambo eziqinile neziqinile.
Bheka Ingabe Kuphephile Ukuqalisa Amakhodi E-Ethernet Ngaphandle? uma ufuna ukukwenza lokho.
Eminye imikhakha ye-Ethernet ye-Computer Networking
Ubuchwepheshe obungenazintambo ezifana ne- Wi-Fi ne- Bluetooth bubeke esikhundleni se-Ethernet kumanethiwekhi amaningi asekhaya namabhizinisi.
