The book is pretty good! Great for the last minute stuff and all that. However, the darn thing says that Windows and Linux are the 2 main Operating Systems for PC's. Seriously? I couldn't trust another word after that. Then when they recognised that Mac's exist, they said that they use a totally different CPU architecture. No, they don't! They did 6 years ago, and I hope to god the book isn't that old, because the specifications aren't!!
There are a cupel of other fact issues (that I spotted, and I'm a student) however they are only there to comply with the specification, and in reality they basically are just keeping away from in depth analysis so no real complaints, however if you are like me, studying ICT and you know a hell of a lot already (unlike those who don't know what a BIOS is), this book will do your head in with the inaccuracies.
