With the emergence of the age of Internet and digital formats of every resource, it was pretty obvious that we would see even books move onto a digital media. An eBook or an electronic book is a book that is either made especially to be one or was originally available in hardback or paperback copies and has been converted to a digital format. There are numerous eBooks and periodicals available online and they are almost the same in presentation and content as a printed book but widely delivered to people electronically. Where there are eBooks, there was definitely something required to read them conveniently. This is where the concept of eBook readers came in.
Electronic book readers are digital devices that are small in size but are making a massive impact on the way books are being read now. The best part about them are that they are small enough to fit in your pocket yet capable of carrying loads of books that could fill up a library perhaps. A digital reader can be understood to be as simple as a PDA or a cell phone where an avid reader can read a novel or it can be considered to be as progressive as a PC from where every format of the eBook can be read.
Some of the pocket eBook readers concentrate only on reading, while there are others that have some fascinating features. Such features include a card reader, a touch-screen, a dictionary and even text-to-speech capability. Some people would like to hear what the words sound like and so the text-to-speech capability is one of the more popular features. Certain other characteristics found in them are Bluetooth, a web browser; Wi-Fi, 3G and some are even capable of playing MP3 songs and show graphic files.
There are several formats that an eBook reader supports such as TXT (text files extension), PDF (Portable Document Format), HTML (HyperText Markup Language), ePub (electronic publication), RTF (Rich Text Format) and Mobipocket. But every format may or may not be supported by a single unit. Also, different brands have different book memory, which can be as little as 256 MB as much as 2 GB.
Similarly, the resolution of the screen in an eBook reader is 600 x 800 pixels however, the ppi or pixels per inch, may be different for different screens. The grayscale levels also differ but fall between 4 and 16. The Battery life depends a lot on page turns and also measured accordingly. The highest value of page turns is 8000. It takes about 3.5 hours and 4 hours to recharge the reader. Some of the brands are as light as 174 g and some as heavy as 343 g. Most of them look slick and display text with great style.
EBook readers are considered to be one of the biggest breakthroughs of technology after the internet. While people still enjoy reading printed books it is doubtful whether ebooks and digital readers will completely replace them anytime soon, but these useful gadgets for sure have their own benefits.
