Unxibelelwano oluninzi lweenethiwekhi zisebenzisa iteknoloji ye-Ethernet
I-Ethernet yi-teknoloji esetyenziswa kakhulu kwiinkonzo zendawo zentambo (i- LAN s). I-LAN yinkonzo yeekhomputha kunye nezinye izixhobo zecomputer ezibandakanya indawo encinci njengegumbi, iofisi okanye isakhiwo. Isetyenziswe ngokungafaniyo nenethiwekhi yendawo eninzi (WAN), ebonisa indawo ezininzi. I-Ethernet ngumgaqo-nkqubo wenethwekhi olawula indlela idatha idluliselwa ngayo kwi-LAN. Ngokomsebenzi kubhekiselwa kuyo njenge-IEEE 802.3 protocol. Umgaqo-nkqubo uguqukele kwaye uphucule ngokuhamba kwexesha ukudlulisa idatha ngejubane yegigabit ngesibini.
Abantu abaninzi baye basebenzisa iteknoloji ye-Ethernet babo ubomi bonke bengayazi. Kunokwenzeka ukuba nayiphi inethiwekhi yocingo eofisini yakho, ebhankini, nakwikhaya yi-Ethernet LAN. Iikhompyutha ezininzi kunye neekhomputha ziza nekhadi le-Ethernet edibeneyo ngaphakathi ukuze zilungele ukuxhuma kwi-Ethernet LAN.
Okokufunayo kwi-Ethernet LAN
Ukusetha i-Ethernet LAN ye-wired, ufuna oku kulandelayo:
- Iikhompyutha kunye nezixhobo zokuxhuma. I-Ethernet idibanisa nayiphina ikhompyutha okanye ezinye iifowuni zombane kwinethiwekhi yayo, nje kuphela ukuba ifowuni ine-adapter ye-Ethernet okanye ikhadi lomnatha.
- Amakhadi womsebenzisi womnxeba kumadivayisi. Ikhadi lomsebenzisi womnatha lidibaniswe kwi-motherboard yekhompyutha okanye efakwe ngokwahlukileyo kwisixhobo. Unayo iinguqulelo ze-USB zamakhadi e-Ethernet afana nama-dongle angaphandle. Ikhadi le-Ethernet liyaziwa njengekhadi lomnatha. It has a port apho ungakwazi ukudibanisa iintambo. Ngokuqhelekileyo kukho izibuko ezimbini, enye ye - Jack ye- RJ-45 edibanisa iimbambo ze-pair (twist) ezingaphenduliweyo kunye nomnye we-Jack coaxial.
- I-router, i-hub okanye isango lokudibanisa izixhobo zakho. I-hub yisistim esenza njengendawo yokuxhuma phakathi kwezixhobo kwinethiwekhi. Iqulethwe ngamanxweme angama-RJ-45 apho uyifakela khona iifowuni.
- Cables. Iikhowudi ze-UTP zisetyenziswa ngokubanzi kwi-Ethernet LANs. Olu luhlobo olufanayo lwekhefu elisetyenziselwa iifowuni zefowuni, kodwa i-fatter, neebhozo ezisibhozo ezithintekileyo zezingcingo zembala eyahlukileyo ngaphakathi. Isiphelo sikhoxiswa ngejack ye-RJ-45, eyona inguqu enkulu yee-RJ-11 ezinokuthi zifake kwifowuni yakho yomhlaba. Xa i-Ethernet ihamba ngaphaya kwegumbi ukuya kumgama omkhulu, ikhebula coaxial isetyenziswe. Le yintambo efanayo kunye ne-jack eyodwa-core usebenzisa i-TV.
- Isoftware ukulawula inethiwekhi. Iinkqubo zokusebenza zanamhlanje njengeenguqulelo zeWindows, iLinux kunye ne-MacOS zaneleyo ukulawula i-Ethernet LANs. Iprojekthi yesithathu-party eyenza iinkalo ezininzi kunye nokulawula okungcono kufumaneka.
Indlela Ethernet isebenza ngayo
I-Ethernet idinga ulwazi lwezobuchwepheshe kwi-computer yesayensi ukuqonda indlela esebenzayo kwi-Ethernet protocol ngokupheleleyo. Nantsi inkcazelo elula: Xa umatshini kwi-intanethi ufuna ukuthumela idatha kwenye, uziva umphathisi-nto, owona mgca ophezulu odibanisa zonke izixhobo. Ukuba inenjongo yamahhala kungekho mntu uthumela nantoni na, ithumela iipakethe yedatha kwinethiwekhi, kunye nazo zonke ezinye izixhobo zijonge ipakethe ukuze zibone ukuba ziyamkela. Ummkeli udla ipakethi. Ukuba kukho kakade ipakethi emgwaqweni omkhulu, ifowuni efuna ukuyibuyisela ibuyele emva kweeyure eziliwaka zeesibini ukuze uzame kwakhona ide ikwazi ukuthumela.
