An ebook is a digital version of a book that can be read on electronic devices such as computers, tablets, and e-readers. Unlike traditional printed books, ebooks are available in various formats, including PDF, EPUB, and MOBI, allowing for easy access and portability. They often come with features like adjustable font sizes, built-in dictionaries, and the ability to highlight text. Ebooks can be purchased or borrowed from online platforms, such as Amazon Kindle or Google Play Books. Many libraries also offer ebook lending services, making it convenient for readers to access a wide range of titles without needing physical copies.
