Kev txhais: Media Access Control (MAC) cov cuab yeej muaj kev cim thiab kev tswj cov computers rau ntawm Internet Protocol (IP) network. Hauv wireless networking, MAC yog lub xov tooj cua tswj kev cai ntawm tus wireless network adapter . Media Access Control ua haujlwm ntawm qes sublayer ntawm cov ntaub ntawv txuas (txheej 2) ntawm OSI qauv .
MAC chaw nyob
Media Access Control assigns ib tug xov tooj tshwj xeeb rau txhua tus IP network adapter hu ua MAC chaw nyob . Qhov chaw nyob MAC yog 48 lub sijhawm ntev. Qhov chaw nyob MAC feem ntau yog sau raws li ib theem ntawm 12 tus lej kawg nkaus li hauv qab no:
- 48-3F-0A-91-00-BC
Qee cov chaw muab kev pabcuam hauv Internet muab cov MAC chaw nyob ntawm ib lub tsev khiav haujlwm rau kev ruaj ntseg. Muaj ntau txoj kev txhawb nqa tus txheej txheem uas hu ua cloning uas tso cai rau MAC qhov chaw nyob kom simulated kom nws sib tw tau ib qhov kev pab cuam yuav tsum yog. Qhov no cia cov tsev neeg hloov lawv lub router (thiab lawv qhov chaw nyob hauv MAC) tsis tas yuav tsum tau qhia rau tus kws kho mob.
