This is really easy to read and understand, unfortunately, it was written in 2003. It is being used for my course in 2009 and much of the information needs updating. For example: Netscape is a popular browser (now extinct), desired computer setup incl Pentium III 750 and 256 RAM and 20 GB of hard disk. Nonetheless, it is giving me a general background. I just have to know that parts are obsolete.
