Aside from books, the internet has been the most useful and helpful resource that people can count on whenever they need to learn more about a certain subject. The only difference is that books can only be read if you will purchase or borrow one from a friend or a public library. However, the internet can provide the convenience that most users long for since web content can be accessed almost anytime, anywhere.
The internet also provides solutions to make things easier for people. If in the past, books can only be accessed at the library or a bookstore, now it is a different case since the birth of a file format called Portable Document Format or PDF. PDF files are like scanned pictures of the content of a book, making it easier for users to read. What is good about PDF files is that there is no way for other people to make changes to it. This is an added protection on the part of the user. The content of the PDF file can also be printed.
There are a lot of web sites that make PDF files available to download, either for free or through subscription basis. The processes and methods behind Prince2, for example, can be downloaded on some sites to make potential users understand better how Prince2 really works. Usually, PDF files are embedded on Prince2 online training web sites to prepare exam candidates on their quest for the certification that they have been longing for. PDF is a file format from Adobe Systems, which was established in 1993.
