what are e books

An e-book, also known as an electronic book, is a book publication made available in electronic form, consisting of text, images, or both, that can be read on the flat-panel display of computers or other electronic devices. E-books can be read on any computing device with the software to display their given file format. They are usually distributed on the internet as downloadable files that can be read offline, as live web pages that must be read online, or as web pages that are cached by a web browser for reading offline. E-books are becoming more popular because they are convenient, less expensive to produce, and take up less space than printed books. They are also searchable, so readers can look for keywords on their device and be taken to the pages of the book with that keyword. E-books can be accessed on multiple devices at once, making them portable and accessible. Some e-books are produced simultaneously with the production of a printed format, while in many instances, they may not be put on sale until later.
