    I have a question regarding voltages. My book(A+ Complete Study Guide 3rd
    Ed., David Groth) mentions all five of the voltages(+3.3VDC, +5VDC, -5VDC,
    +12VDC, -12VDC) but, only says what, four of the five voltages are for.
    Also, It says that, the 3.3V and, +5VDC are, standbys' specific to ATX
    motherboards and, that, -5VDC and -12VDC are specific to 'ground'. What
    about the +12VDC. I will look this up on the WWW but, I would still like
    an answer, as, that may come sooner than, what I find on the WWW.

    TIA
