I did, too, and felt that some of the other questions suffered from imprecise or confusing wording. Example, what's the largest number that can be stored in a byte? The answer was 256, but it really should have been 255, since it takes 2 bytes to store a value of 256 ($01 $00). Since 255 wasn't one of the possible choices, I was able to choose the "correct" answer, but really either the question should have been "How many different values can be stored in a byte?" or the multiple-choice answers should have included 255 rather than 256.
