I love e-books, I wonder how they work.
I enjoy e-books too! They're basically just a high-tech Word program that you can download and read on an e-reader, desktop, laptop, tablet, smartphone, etc.
I did not think of that, are they popular ?
They are fairly popular! One of the things I love about them is that you can browse books online, then download a book you want in just a few seconds.
That is practical, and who invented the e-book ?
A guy name Michael Hart invented the e-book way back in the 1970s!
This is older than I thought. Is there just one format of e-book or they are multiple types of e-books ?
There are different types! Hart founded Project Gutenberg, which presents books as plain text files online. Kindle and Kobo books are much more advanced.
oh thanks a lot, bye
