Operating system
A software product that ensures the correct operation of the installed software and convenient management of e-book functions. Conventionally, the family of "readers" is divided into two large camps: some work under the
Android OS (in various versions of
Android 10,
Android 11,
Android 12,
Android 13,
Android 14), others run Linux. The Android system is not always well adapted to the features of the e-book interface, but a significant trump card up its sleeve is support for installing applications from the Google store.
Linux -led readers stay afloat longer in offline mode, but most of them cannot be installed with third-party applications.
CPU speed
The frequency of the built-in e-book processor is one of the main indicators that determine its performance (the speed of copying files to the built-in memory, opening larger files, loading Internet pages, etc.). On the other hand, this indicator is not decisive and can only be used for comparison in books of the same model range.
RAM
The amount of the reader's own RAM, that is, the memory used for temporary data storage during operation. The speed of the e-book directly depends on the amount of RAM, especially when working with large files. So the average value can be considered
RAM 1 GB and
2 GB, and more advanced models have
3 GB,
4 GB and even
6 GB of memory.
Data transfer
—
Wi-Fi. A wireless communication module that allows you to connect the reader to wireless local (home or office) networks, as well as access the Internet through public access points (hot spots) installed in restaurants, hotels, railway stations, etc.
—
Bluetooth. Direct wireless communication technology between various electronic devices. In e-readers, Bluetooth is primarily used for file transfer: with this function, you can connect the reader to another Bluetooth device, such as a laptop or tablet PC, and exchange files with it.
— microUSB. Connector for direct connection of the reader to the USB port of the computer using a special cable. In e-books, this connection is used primarily for file sharing. MicroUSB is a universal standard that allows you to connect various gadgets through it with one cable.
— miniUSB. Similar to the one described above, the connector, which differs only in the size and shape of the connector.
—
USB-C. Symmetrical USB connector, which is gaining popularity and in the future is able to displace microUSB. At the same time, the connector has a high data transfer rate and is only a little larger in size.
