Abaphindaphindayo: IiNdawo zokuHlaziywa ngokutsha kweSignali kwiiNethiwekhi zoNxibelelwano

Eziphinda-phindayo ziziseko ezingundoqo ezibalulekileyo kuthungelwano lonxibelelwano lwale mihla. Umsebenzi wabo ophambili kukujongana nokuthotywa komqondiso obangelwa kukuthotywa komgama okanye ukuphazamiseka ngexesha lokuhanjiswa. Njengenxalenye ephambili yomaleko womzimba, abaphindayo basebenzisa itekhnoloji echanekileyo yokulungisa umqondiso we-elektroniki ukwandisa ngokuthembekileyo amakhonkco onxibelelwano.

Ngokobuchwephesha, abaphindayo basebenza ngokupheleleyo-kwimowudi ephindwe kabini, ukukhulisa, ukumila, kunye nokunciphisa ixesha lophawu lokuqala oluncitshisiweyo ekupheleni kokufumana. Xa iimpawu zombane okanye zamehlo zihamba imigama emide, i-amplitude yazo ibola ngokuthe ngcembe kwaye amaza amaza ayagqwetheka. Oku kugqwetheka kunokunyusa amazinga eempazamo ezincinci ekupheleni kokufumana. Abaphindayo babuyisela amandla ophawu kusetyenziswa{4}}iisekethe zokukhulisa ezichanekileyo kwaye basebenzise ubuchwephesha bokubunjwa kobume bemaza ukuphelisa uphazamiseko lwengxolo, ekugqibeleni kuphinda kuhanjiswe isignali esetyenzisiweyo, ecocekileyo kwindawo yothumelo elandelayo. Kunxibelelwano lwefiber-optic optic, ii-optoelectronic repeaters zisenokwenza ukubona{7}}ukuya{8}}kombane{9}}ukuya{10}}uguqulo lwamehlo, ngokwandisa umgama wothumelo lwefayibha ukuya kumakhulu eekhilomitha.

Abaphindayo banoluhlu olubanzi lwezicelo. Kuthungelwano lweentambo zesiNtu, i-twisted -iperi i-Ethernet isebenzisa ii-hubs (eziphinda-phinda) ukudibanisa iindawo ezininzi; izikhululo ezisisiseko zonxibelelwano ezingenazingcingo zixhomekeke kwizikhululo zonxibelelwano ukuze zandise ukhuseleko; kunye nemishini yokuhlola indawo enzulu ixhomekeke kuthotho lweesathelayithi ezikhutshelwayo ukwakha ibhulorho yonxibelelwano phakathi koMhlaba neNyanga. Kwi-Intanethi ye-Intanethi yeZinto yangoku, uphazamiseko{3}}abaphindayo baqinisekisa ukuhanjiswa kwedatha okuzinzileyo kwiindawo ezirhabaxa.

Ngokuzivelela kwetekhnoloji, abaphindayo abakrelekrele ngoku baneempawu eziphambili ezinjengolawulo lokuzuza oluguquguqukayo kunye nokuxilongwa kwempazamo. Ngaphandle kophuhliso oluqhubekayo lwezixhobo zenqanaba eliphezulu kwimodeli ye-OSI, abaphindayo, ngokulula kunye nokuthembeka kwabo, bagcina indawo engenakuphinda ithathelwe indawo kulwakhiwo lothungelwano olusisiseko lonxibelelwano, lube yinxalenye yembombo ekwakheni ihlabathi ledijithali eliqhagamshelwe kwihlabathi.
