What Media Access Control protocol does Ethernet and IEE 802.e use ?

CSMA persistent ? CSMA/CD ? CSMA non persistent ? CSMA / CA ?

And IEEE 802.11 uses CSMA / CA , right ?

For your information, it is not homework questions.
I like to study computer networks, and Im reading some books. Some of
these books tells 802.3 uses CSMA/CD 1 persistent , but Im not sure.

I assume you mean 802.3, not 802.e (the keys are adjacent on a qwerty
keyboard).

Ethernet/802.3 uses 1-persistent CSMA, with collision detect (in
half-duplex mode).

You can read all the gory details yourself on IEEE's web site.

Or for a summary, see
