Digital Rights Management (DRM) stands for the copyright protection system that is used to secure electronic files. DRM protects ebooks from being abused (free use, copying, etc.). Alza uses two types: Social DRM and Adobe DRM.
An eBook is a digital version of a classic paper book designed for reading on specialized readers, tablets, smartphones or computers. You can download the ebook in a matter of minutes, and in the vast majority of cases it comes cheaper than the classic printed version. The flexibility to change the font size while reading is a great advantage for some.
