    They are two, different cellular networking technologies & explaining them "in detail" in a forum like this isn't really very practical.

    GSM is used by close to 90% of the world's cellular phone users, or about 1 billion subscribers.

    CDMA is primarily used in the U.S. and South Korea. The number of CDMA subscribers are in the range of 200 million today.

    For details about GSM, start with, e.g., these sites:
    http://www.gsmworld.com/index.shtml
    http://www.nokia.com/nokia/0,8764,56837,00.html

    For details about CDMA, start, e.g., here:
    http://www.qualcomm.com/technology/cdma101.html

    I'm sure that a google.com or amazon.com search will also yield more details (links, papers, books) that you can easily digest.
