Technical progress does not stand still, andmanufacturers of various electronic devices delight consumers with new and new "devices". There was even an alternative to the usual paper books - an e-book. The country of the Soviets will tell, how to choose an e-book.
E-book (Electronic Book, eBook, e-Book) Is an electronic device designed forreading electronic texts in various formats. But why buy a separate device, if you can read the test from a laptop or netbook monitor? The main advantage of an e-book is a special screen. When manufacturing the screen of most e-books, technology is used E-Ink (electronic ink). Such a screen is similar to ordinary paper, almost does not tire eyesight and reduces power consumption.
So, how to choose an e-book? There are several selection criteria, but the most important, of course, is display. Reading an e-book should becomfortable, which means that the display should be large enough to fit at least one full paragraph of text, or even better - a whole page. Therefore, it is very important to pay attention to screen diagonal and its resolution. The minimum acceptable parameters are a diagonal of 5.6 inches and a resolution of 320x460 pixels. Most modern electronic books have a diagonal of 6 inches and higher and a resolution of 600x800 pixels.
In addition to these characteristics, it is important to pay attention to display type. E-Ink displays, of which we have already mentioned above, differreduced energy consumption and less eye strain. But with such displays it is almost impossible to read in poor lighting, in addition, they do not support video playback. Liquid Crystal Displays (LCD) are rich in color, equipped with backlighting,can play video and colorful illustrations. But such displays create an increased strain on the eyes, and the battery life of such a book is less than that of a book with a paper-like display.
When deciding to choose an e-book, pay attention to Memory - it is he who determines the number of books thatyou can upload to your device. The amount of internal memory is usually enough to load at least 100 books with illustrations or 500 - without. If you want to download more books or are going to listen to music while reading (some books support MP3 playback), you will need to select an e-book with memory card slot. Most modern "readers" have slots for memory cards SD or micro SD up to 16 GB.
Go ahead. A very important criterion for choosing an e-book is the file formats it supports. The minimum "gentleman's set" supported e-book formats - This is TXT, RTF, HTML, FB2. Some "readers" additionally recognize the formats DOC, CHM, DJVU, EPUB, TCR, PRC, and also are able to extract files from zip-archives. Be prepared for the fact that you may have difficulties with reading PDF files - yet this format is not intended for reading, so no e-book can open absolutely any PDF file without errors.
In addition to text formats, most e-books recognize the format of JPEG images (this is true for books with illustrations), and some models may be "familiar" with other image formats - for example, GIF, PNG, BMP, TIFF.
Some books play MP3 format. Why is this necessary? First, some people prefer not to read in silence, but rather with musical accompaniment. Secondly, you can play an audiobook on such a "reader". If you decide to select an e-book that plays MP3, you need to pay attention to the presence of built-in speakers, and if you need it to play audiobooks, then you can easily navigate audio files.
Besides, When choosing an e-book, you should pay attention to:
battery life time
Availability of Wi-Fi module for Internet access
convenience of navigation buttons location
presence of a protective cover
presence of illumination; for models with illumination - the ability to adjust brightness and contrast
screen background color
angle of view
the presence of touchscreen (touch screen)
weight and size of the book
possibility of changing the battery
presence of the Russian interface
Now you know how to choose an e-book. We hope, our advice will help you not to get confused when you come across variety of assortment of electronic "readers".
