Many people always wonder to themselves how computers work. The only problem is that when you try to find a book or a site that will explain it then they always lack diagrams. Roger Young, however, has put together a very good book that is now available for everyone to enjoy at no cost. The book is called How Computers Work and provides you with 152 pages of quality content and 96 diagrams! However, It is not a book that a novice user will be able to easily understand so you should have some knowledge of computers before starting to read this. Happy reading!
