Hamwe niterambere ryinganda zitumanaho no kumenyekanisha ubukungu bwigihugu ,. gucunga imiyoboro y'impetaisoko ryazamutse neza.Birahenze cyane, byoroshye cyane, byoroshye kandi byoroshye kubishyira mubikorwa.Ikoranabuhanga rya Ethernet ryahindutse ikoranabuhanga ryingenzi rya LAN muri iki gihe, kandi gucunga impeta byahindutse ibyamamare.
Guhindura bikora kumurongo wa 2 (guhuza amakuru) murwego rwa OSI rwerekana.Iyo buri interineti ihujwe neza, CPU imbere muri switch izakora imbonerahamwe ya MAC mugushushanya aderesi ya MAC kuri interineti.Mu itumanaho rizaza, paki zigenewe iyo aderesi ya MAC izoherezwa gusa kuri interineti ihuye, ntabwo ari intera zose.Kubwibyo, imiyoboro iyobora imiyoboro irashobora gukoreshwa kugirango igabanye ikwirakwizwa ryamakuru ahuza urwego, ni ukuvuga urwego rwo kugongana;ariko ntishobora kugabanya itumanaho ryurusobe, ni ukuvuga indangarubuga.
Gucunga impeta ihinduranya ifite umurongo muremure cyane wa bus bus na matrix imbere.Imigaragarire yose ya switch ihujwe niyi bus ihinduka.Nyuma yumuzunguruko wakira paki, interineti itunganya izareba imbonerahamwe yo kugereranya adresse yibuka kugirango umenye NIC (ikarita y'urusobe) yintego MAC (aderesi yibikoresho byikarita y'urusobe).Ni ubuhe busobanuro paki ihita yoherezwa mugihe cyerekezo binyuze mumyenda yimbere.Niba aho MAC idahari, iyitange kuri interineti zose.Nyuma yo guhinduranya yakiriye igisubizo kivuye kuri interineti, "iziga" adresse nshya ya MAC ikayongera kumeza yimbere ya MAC imbere.Gukoresha sisitemu birashobora kandi "gutandukanya" umuyoboro.Mugereranije imbonerahamwe ya aderesi ya IP, gucunga impeta byemerera gusa imiyoboro ya neti ikenewe kunyura muri switch.Hindura gushungura no kohereza birashobora kugabanya neza kugongana.
