I do not want answers, I just need a couple of websites so I can get the information my self.
I am looking for something about CSMA/CD for my Networking class that I am taking. Like I said I am just looking for information on a website. I have the definition now I need what it does and how it works.
I would appreciate any information anyone can give me.
Thank you.

    Here is an RFC:
    http://www.faqs.org/rfcs/rfc1180.html

    The excerpt on CSMA/CD is vey good:
    Ethernet uses CSMA/CD (Carrier Sense and Multiple Access with
    Collision Detection). CSMA/CD means that all devices communicate on
    a single medium, that only one can transmit at a time, and that they
    can all receive simultaneously. If 2 devices try to transmit at the
    same instant, the transmit collision is detected, and both devices
    wait a random (but short) period before trying to transmit again.

    3.1 A Human Analogy

    A good analogy of Ethernet technology is a group of people talking in
    a small, completely dark room. In this analogy, the physical network
    medium is sound waves on air in the room instead of electrical
    signals on a coaxial cable.

    Each person can hear the words when another is talking (Carrier
    Sense). Everyone in the room has equal capability to talk (Multiple
    Access), but none of them give lengthy speeches because they are
    polite. If a person is impolite, he is asked to leave the room
    (i.e., thrown off the net).

    No one talks while another is speaking. But if two people start
    speaking at the same instant, each of them know this because each
    hears something they haven't said (Collision Detection). When these
    two people notice this condition, they wait for a moment, then one
    begins talking. The other hears the talking and waits for the first
    to finish before beginning his own speech.

    Each person has an unique name (unique Ethernet address) to avoid
    confusion. Every time one of them talks, he prefaces the message
    with the name of the person he is talking to and with his own name
    (Ethernet destination and source address, respectively), i.e., "Hello
    Jane, this is Jack, ..blah blah blah...". If the sender wants to
    talk to everyone he might say "everyone" (broadcast address), i.e.,
    "Hello Everyone, this is Jack, ..blah blah blah...".
    All things are possible, only believe.

    Thank you very much. I believe I have everything I need for now for the short report. In 3 weeks I have to write a 1500 word page report. Thank you again. :D:D:D:)
