How to choose the electronic book?
|/img >/img src="//images/stories/tip/comp-progs/e-book-choice_small.jpg" alt="How to choose the electronic book?" align=left title="Как выбрать электронную книгу?" />Technical progress does not stand still, and producers of various electronic devices please consumers all with new and new "devices". There was even an alternative to habitual paper books — the electronic book. Infoadvisor.net will tell how to choose the electronic book. |
The electronic book (Electronic Book, eBook, e-Book) — this electronic device intended for reading electronic texts in various formats. But why to buy the separate device if it is possible to read the test from the monitor of the laptop or the netbook? The main advantage of the electronic book — is the special screen. At production of the screen of the majority of electronic books the E-Ink technology (electronic ink) is used. Such screen is similar to usual paper, sight practically does not tire and reduces energy consumption.
So, how to choose the electronic book? There are some criteria of a choice, but the most important, of course, it is the display. Reading the electronic book has to be comfortable, and it means that the display has to be rather big that on it one full paragraph of the text went in at least, and it is even better — the whole page. Therefore it is very important to pay attention to a diagonal of the screen and its permission. The minimum acceptable parameters — a diagonal 5,6 inches and resolution of 320х460 pixels. The majority of modern electronic books have a diagonal of 6 inches and also resolution of 600х800 pixels is higher.
Except these characteristics it is important to pay attention to display type. E-Ink displays about which we already mentioned above, differ in the lowered energy consumption and smaller load of eyes. But from such displays it is almost impossible to read at bad lighting, besides, they do not support reproduction of video. Liquid crystal displays (LCD) differ in richness of color, are equipped with illumination, can reproduce video and colourful illustrations. But such displays create the raised load of eyes, and time of autonomous work of such book is less, than at the book with the bumagopodobny display.
Having decided to choose the electronic book, pay attention to memory size — it defines number of books which you will be able to load into the device. The volume of the built-in memory usually is enough to load not less than 100 books with illustrations or 500 — without. If you want to load more books or are going to listen during reading to music (some books support reproduction of the MP3 format), you should choose the electronic book with a memory card slot. The majority of modern "eReaders" have slots for SD or micro SD memory cards with a capacity up to 16 Gb.
We go further. Very important criterion of a choice of the electronic book — is the formats of files supported by it. Minimum "the gentlemen's set" of the formats supported by the electronic book — is TXT, RTF, HTML, FB2. Some "eReaders" in addition distinguish the DOC, CHM, DJVU, EPUB, TCR, PRC formats, and also are able to take files from zip-archives. Be ready to that you can have difficulties with reading PDF of files — after all this format is not intended for reading therefore any electronic book will not be able to open any PDF the file without errors.
Except text formats, the majority of electronic books distinguish a format of images JPEG (it actually for books with illustrations), and some models can be "familiar" with other formats of pictures — for example, GIF, PNG, BMP, TIFF.
Some books reproduce the MP3 format. Why it is necessary? First, some prefer to read not in silence, and under music. Secondly, you will be able to reproduce on such "eReader" of the audiobook. If you decided to choose the electronic book reproducing a MP3 to you it is necessary to pay attention to existence of the built-in loudspeakers and if it is necessary to you for reproduction of audiobooks — that and on convenient navigation according to audio-files.
Besides, at a choice of the electronic book it is worth paying attention on:
Now you know how to choose the electronic book. We hope, our councils will help you not to become puzzled when you face variety of the range of electronic "eReaders".
