An E-Book Reader is a portable electronic device designed specifically for reading digital books, known as e-books. These devices use e-ink technology to mimic the appearance of printed paper, making it easier on the eyes compared to traditional screens. E-book readers often come with features like adjustable font sizes, built-in dictionaries, and the ability to store thousands of books. Many e-book readers also offer wireless connectivity, allowing users to download books directly from online stores. Popular models include the Amazon Kindle and Kobo, which provide access to vast libraries of literature, making reading more convenient and accessible.
