Incazelo: Ubuchwepheshe beMedia Access Control (MAC) inikeza ukuhlonza okuyingqayizivele nokulawula kokufinyelela kwamakhompyutha kwinethiwekhi ye- Inthanethi Protocol (IP) . Ezingxenyeni ezingenazintambo, i-MAC yinkqubo yokulawula umsakazo ku- adaptha yenethiwekhi engenantambo. Ukulawulwa kokufinyelela kweMidiya kusebenza ngaphansi kwe-sublayer engezansi kwesendlalelo sokuxhumanisa idatha (Isendlalelo 2) se- OSI model .
Amakheli e-MAC
I-Media Access Control inikeza inombolo eyingqayizivele ku-adaptha yenethiwekhi ngayinye ye-IP ebizwa ngokuthi ikheli le-MAC . Ikheli le-MAC linama-bits angu-48 ubude. Ikheli le-MAC livame ukulotshwe njengokulandelana kwamadijithi angu-12 hexadecimal kanje:
- 48-3F-0A-91-00-BC
Abanye abanikezeli bezinsizakalo ze-intanethi balandelela ikheli le-MAC le -router ekhaya ngezinhloso zokuphepha. Ama-routers amaningi asekela inqubo ebizwa ngokuthi i- cloning evumela ukuthi ikheli le-MAC lifanelwe ukuze lihambelane nomunye umhlinzeki wesevisi elilindele. Lokhu kuvumela amakhaya ukuthi ashintshe i-router yabo (kanye nekheli lawo langempela le-MAC) ngaphandle kokukwazisa umhlinzeki.
