Please suggest me a good book on computer. Not programming book. A genral book which covers brief history of computer,a general idea of programming, hardware etc. from a broader perspective. It doesn't have to be one book. I am not talking about the ABC of computer, or a book for non technological person. But book(s) that covers different parts of computer like hardware,software, history of computers etc. ... like a book to revise your current knowledge, or a must have book in your shelf if you are a programmer or hardware eng. whatever. I hope you get the point. Any suggestion is most welcome thank you
