Digital books refer to electronic or digital versions of traditional printed books that are available in a format that can be read on a computer, e-reader device such as Kindle or Nook, smartphone or tablet. These books are usually downloaded and stored electronically rather than being printed out on paper. They offer several advantages over physical books including portability, accessibility (as they can be easily downloaded), searchability (using keywords or phrases) and the ability to adjust font size for easier reading. Additionally, digital books often include interactive features such as embedded links, audio/video content, highlighting and note-taking capabilities that enhance the reader's experience.
