Answer:
The answer is an e-book (electronic book).
Step-by-step explanation:
An e-book refers to a book publication that is available in digital form. It is usually composed of text, images or both of them and we can read it on the flat-panel display that we can see on computers as well as in other electronic devices.
It is usually called "an electronic version of a printed book". However, we can see some e-books without the existence of a printed equivalent. We can read e-books on desktop computers, laptops, tablets as well as smartphones. People buy e-books because there are lower prices, people feel more comfortable and also because there is a larger selection of titles.
