What is an eBook?
An eBook is a non-editable electronic book, a reflowable book that is converted to a digital format to be read on any digital device such as computer screens or mobile devices.

An eBook, short for electronic book, is a digital version of a traditional printed book that can be read on electronic devices such as computers, smartphones, tablets, and dedicated eReaders. eBooks are designed to replicate the content and structure of a physical book, including text, images, and sometimes multimedia elements, in a digital format.

eBooks come in various formats, each with its own characteristics and compatibility with different devices and software. Some common eBook formats include:

1. EPUB (Electronic Publication): This is a widely used and versatile format that adapts well to different screen sizes and devices. EPUB files are reflowable, meaning the text and images adjust dynamically based on the reader’s preferences and device specifications.

2. PDF (Portable Document Format): PDF eBooks maintain the layout and design of a printed book, making them suitable for documents with complex formatting. However, PDFs may not always adjust well to different screen sizes and can be less flexible for adjusting font size and layout.

3. MOBI (Mobipocket): Originally developed for Mobipocket eReaders, the MOBI format is commonly used for Amazon Kindle eBooks. Like EPUB, MOBI supports reflowable text, making it adaptable to various devices.

4. AZW (Amazon Kindle eBook format): Amazon’s proprietary eBook format used for Kindle devices and apps. AZW files can contain various Kindle-specific features.

5. iBooks (Apple’s eBook format): Designed for Apple’s iBooks app, this format supports multimedia elements and interactive features.

eBooks offer several advantages over traditional printed books, including:

– Portability: A single device can store thousands of eBooks, allowing readers to carry an extensive library wherever they go.
– Accessibility: eBooks can be downloaded and accessed instantly from online stores, making them convenient for purchasing and reading.
– Customization: Readers can adjust font size, style, and background color to suit their preferences and improve readability.
– Searchability: eBooks often include search functionality, enabling readers to quickly find specific information or passages.
– Cost-effectiveness: eBooks are often more affordable than printed books, and there are also many free and public domain eBooks available.

Overall, eBooks have transformed the way people read and access written content, offering greater convenience and flexibility in comparison to traditional print media.

What is an eReader?

An eReader, short for electronic reader or eBook reader, is a portable electronic device designed for reading digital books, magazines, newspapers, and other written content. It provides a convenient and portable way to access and read a wide range of digital publications without the need for physical books or printed materials.

eReaders typically use E Ink (electronic ink) technology, which mimics the appearance of printed text on paper, resulting in a reading experience that is easy on the eyes and can be comfortably read in various lighting conditions, including bright sunlight. This technology also contributes to extended battery life compared to other devices like smartphones or tablets.

eReaders usually have features such as adjustable font size, font style, and screen brightness to accommodate different reading preferences. They often support various eBook formats, including EPUB, PDF, and MOBI, allowing users to access content from different sources and publishers.

Some popular eReader brands include Amazon Kindle, Barnes & Noble Nook, Kobo, and Sony Reader, among others. These devices have become increasingly popular due to their portability, ease of use, and the ability to carry a vast library of books in a single device.
