Amanethiwekhi amanethiwekhi amaningi asebenzisa ubuchwepheshe be-Ethernet
I-Ethernet ubuchwepheshe obuvame ukusetshenziselwa amanethiwekhi wendawo wambo (i- LAN s). I-LAN iyinethiwekhi yamakhompyutha namanye amadivaysi e-elektroniki afaka indawo encane efana negumbi, ihhovisi noma isakhiwo. Isetshenziswe ngokungafani nenethiwekhi yendawo enkulu (i-WAN), esho izindawo eziningi kakhulu ezindawo. I-Ethernet iyi-protocol yenethiwekhi elawula ukuthi idatha idluliselwa kanjani ku-LAN. Ngokusemthethweni kuthiwa yi-IEEE 802.3 protocol. Le protocol ishintshiwe futhi ithuthukisiwe ngokuhamba kwesikhathi ukudlulisa idatha ngesivinini segigabit ngomzuzwana.
Abantu abaningi baye basebenzisa ubuchwepheshe be-Ethernet babo bonke ukuphila ngaphandle kokukwazi. Kungenzeka ukuthi kunoma yikuphi inethiwekhi yocingo ehhovisi lakho, ebhange, nasekhaya yi-Ethernet LAN. Amakhompyutha amaningi edeskithophu ne-laptop afika nekhadi le-Ethernet elididiyelwe ngaphakathi ngakho balungele ukuxhuma ku-Ethernet LAN.
Okudingayo ku-Ethernet LAN
Ukusetha i-LAN Ethernet LAN, udinga lokhu okulandelayo:
- Amakhompyutha namadivayisi ukuxhuma. I-Ethernet ixhuma noma yikuphi ikhompuyutha noma amanye amadivaysi kagesi kwinethiwekhi yayo uma nje idivayisi ine-adapter ye-Ethernet noma ikhadi lenethiwekhi.
- Amakhadi wombukiso wenethiwekhi kumadivayisi. Ikhadi lesikhangiso se-network lihlanganiswe phakathi kwebhodi le-motherboard yekhompuyutha noma efakwe ngokwehlukile kudivayisi. Futhi unezinguqulo ze-USB zekhadi le-Ethernet njenge-dongles yangaphandle. Ikhadi le-Ethernet liyaziwa njengekhadi lenethiwekhi. Inamapayipi lapho ungaxhuma khona izintambo. Ngokuvamile kunezikebhe ezimbili, enye ye - Jack RJ-45 ehlanganisa izintambo ezimbili ezingaphenduliwe (UTP) kanye nomunye we-Jack coaxial.
- I-router, ihabhu noma isango lokuxhuma amadivayisi wakho. Ihabhu iyisidingo esisebenza njengephuzu lokuxhuma phakathi kwamadivayisi kunethiwekhi. Iqukethe amathrekhi amaningana e-RJ-45 okufaka kuwo amakhodi.
- Amakhodi. Amakhodi we-UTP avame ukusetshenziswa ema-LAN Ethernet. Lona uhlobo olufanayo lwekhebula elisetshenziselwa amasethi ocingweni lwendawo, kodwa i-fatter, enezinhlangothi eziyisishiyagalombili zinezintambo zezambo zombala ohlukahlukene ngaphakathi. Ukuphela kuphethwe ngejaji ye-RJ-45, okuyiyona inguqulo enkulu yama-RJ-11 ama-pack agxila kufoni yakho. Lapho i-Ethernet ihamba ngaphesheya kwekamelo ukuya kude, ikhebula le-coaxial lisetshenziswa. Leli yikhebula elifanayo ne-round single-core jack oyisebenzisayo ku-TV.
- Isofthiwe yokuphatha inethiwekhi. Izinhlelo zokusebenza zanamuhla ezinjengezinguqulo zamuva zeWindows, i-Linux ne-MacOS zingaphezu kokwanele ukuphatha i-Ethernet LANs. Isofthiwe yenkampani yesithathu enikeza izici eziningi nokulawula okungcono kuyatholakala.
I-Ethernet isebenza kanjani
I-Ethernet idinga ulwazi lwezobuchwepheshe kwisayensi yekhompiyutha ukuqonda indlela elandela i-protocol e-Ethernet ngokugcwele. Nansi incazelo elula: Uma umshini onethiwekhi ufuna ukuthumela idatha komunye, uzwa othwala, okuyinto wire main ukuxhuma wonke amadivaysi. Uma kunenkululeko yamahhala akekho othumela noma yini, ithumela iphakethe yedatha kwinethiwekhi, futhi wonke amanye amadivayisi ahlole iphakethe ukuze abone ukuthi ingabe uyamukeli. Umamukeli udla iphakethe. Uma kukhona kakade iphakethe emgwaqweni omkhulu, idivayisi efuna ukuyithumela iphinda ibuyele emuva kwezingu-1000 zeyesibili ukuzama futhi ize ithumele.
