Los ntawm Wikipedia, phau ntawv dawb encyclopedia. Carrier-sense ntau nkag nrog kev sib tsoo kom zam ( CSMA / CA ) nyob rau hauv lub computer networking, yog ib tug network ntau txoj kev nkag mus siv nyob rau hauv lub carrier sensing yog siv, tab sis cov nodes sim kom tsis txhob muaj kev sib tsoo los ntawm pib kis tau tus mob tsuas yog tom qab lub channel paub tias yog "tsis ua hauj lwm".

Xav txog qhov no, CSMA raws tu qauv yog dab tsi?

Carrier-sense ntau nkag tau ( CSMA ) yog Media Access Control (MAC) raws tu qauv nyob rau hauv uas ib tug node txheeb xyuas qhov tsis muaj lwm yam tsheb ua ntej kis tau tus mob ntawm ib tug sib kis nruab nrab, xws li ib tug hluav taws xob tsheb npav los yog ib tug band ntawm lub electromagnetic spectrum.

Ib yam li ntawd, qhov txawv ntawm CSMA CD thiab CSMA CA yog dab tsi? 1. CSMA CD siv tau tom qab kev sib tsoo thaum CSMA CA siv tau ua ntej kev sib tsoo. 2. CSMA CA txo qhov muaj peev xwm ntawm kev sib tsoo thaum CSMA CD tsuas yog minimizes lub sij hawm rov qab.

Kuj paub, CSMA CA siv rau dab tsi?

CSMA / CA (Carrier Sense Multiple Access/Collision Avoidance) yog cov txheej txheem rau kev sib kis hauv 802.11 tes hauj lwm. Tsis zoo li CSMA / CD (Carrier Sense Multiple Access/Collision Detect) uas cuam tshuam nrog kev sib kis tom qab muaj kev sib tsoo, CSMA / CA ua los tiv thaiv kev sib tsoo ua ntej lawv tshwm sim.

CSMA CA ua haujlwm li cas hauv WIFI?

Carrier Sense Multiple Access/nrog kev sib tsoo sib tsoo ( CSMA / CA ) yog ib qho kev sib cav sib ceg hauv lub network siv rau kev sib kis hauv cov xov tooj siv 802.11 tus qauv. CSMA / CA tsub kom lub network khiav raws li nws yuav tsum tau xa tawm lub teeb liab mus rau lub network txawm ua ntej xa cov ntaub ntawv tiag tiag.
