A+ Certification Practice Questions Exam Cram 2 (Exams: 220-301, 220-302) Review by Steven Wilson

Good review, too long and many errors

Though the book is a good review, it seems to jog wildly off topic for a typical exam cram. My idea of an exam cram is just the information you need to pass the exam. I'm not interested in a history lesson of PC technologies or in-depth discussions of signalling that isn't covered on the exam and isn't used except by hardware engineers.

Secondly, there are many errors, particularly the wireless section which has some serious errors. For example, the book says that 802.11b uses FHSS and 802.11g uses DSSS. This is clearly false. 802.11b uses DSSS, and 802.11g uses OFDM. There are no excuses for these types of errors.
