An e-book is an electronic book, or a book consisting of a computer file, itself a collection of digital information, such as Adobe's 'pdf' or 'portable document format'. more...

The Adobe 'pdf' has the advantage that anyone can view or print the document using the free 'Acrobat' reader software available as a free download. (In other words, you don't need the often expensive program that was originally used to create the e-book in the first place). Many programs can be used to create pdf's (usually by choosing 'save as' in the file menu and then files of type 'pdf').
The information for the text and images in an e-book is processed in a number of possible ways (by scanning, for example, or created in a software program), to turn it into numbers, or 'digits'. E-books, or electronic books, are for viewing on electronic devices, not only desktop computers, but also laptops, the newer, smaller, net-books, as well as hand-held - personal digital assistants and even the newer, larger screened cellphones.
E-books can now also be read on dedicated e-book readers, which should not be underestimated. Although seemingly expensive, e-book readers are very light, extremely portable and yet can hold hundreds of e-books including novels and text books as well as connecting to the internet and downloading the latest daily newspaper from anywhere, instantly. You can also surf the web and send e-mail from them.
So, some of the advantages of e-books are to save trees, instantly downloadable, easily reproducible, no printing costs, take up no physical space. E-books can be sent anywhere in the world in seconds, can be viewed and printed by anyone with a normal computer setup, cost nothing to reproduce and for me, one of the most attractive benefits, is that they are extremely easy to create.
The 'digital revolution' is, the way I see it, the way in which our lives are changing due to new ways of creating, manipulating and distributing the 'printed' word. I love e-books because I love information and I love the ease of which digital processes allow that information to be disseminated.
