Query: OS section is good, but this book is lacking

OS section did a good job covering Windows 2000/NT/98/95 and DOS. The hardware section was lengthy, but studying it alone would not allow you to pass the hardware module of the adaptive A+ certification test. I passed, not because of this book, but experience.There were several gaps left unfilled between the actual test and this book. For instance, I was asked a question on the difference between ATA/66 and ATA/33. Neither cable is mentioned in this book. Another question delt with the difference between an AT mobo and an ATX. After looking back in this book, the answer was not there. There are several other examples like this. My advice...look elsewhere, especially at this price.
