Where to find sources on Full Adders

    Where to find sources on "Full Adders"

    Ok. So I have been reading and watching this stuff on 4 bit computers. I understand how to read binary code however I am having trouble with the concept of the "full adder"

    This is what I have been reading
    first off

    Does anyone know of a better more in depth source for learning about 4 bit computers and full adders and transistors? I would really like to learn more, but information online is highly lacking.

    This is the site i have been using

    A full adder is a piece of logic. It adds one bit of a binary number to the corresponding bit of another binary number along with any Carry in. The result is the Sum bit and a Carry out.

    If I were you, I would first worry about how the logic works and how you would build a full adder outa gates, not physical devices like transistors.

    Maybe this is useful: http://en.wikipedia.org/wiki/Full_adder
