Just an example of how the author doesn't know what (s)he's talking about:"Probably the best-known technologies used by processors are Intel's Hyper-Threading and AMD's HyperTransport. Both allow each logical processor within the processor package to handle an individual thread in parallel with other threads being handled by other processors within the package."This is an elementary error, that even amateur hardware enthusiasts know is wrong. Hyper-Threading and HyperTransport are two very different things. The former is what the author describes, the latter is a bus. It suggests that the author doesn't know much about hardware, and probably created the book by googling and using sources that may, or may not be correct.
