Blackview Tab 13, 6GB/128GB, Space Gray

The screen is the most important component of the tablet computer and its size determines the size of the tablet computer. Usually it is the diameter of the screen plus a couple of centimeters of the "holding part".

For convenient use we recommend approximately 10" tablet computers. 7" screen can be considered small and better suitable for children. If the tablet computer has the screen with the size exceeding 10" it means that the device is quite big and can seem inconvenient for an average user.

Indicates the number of dots the screen contains horizontally and vertically. The higher this parameter the better the sharpness of the image and the more pleasant use.

This index indicates the colour compliance, brightness, viewing angle and other quality criteria. Any AMOLED, PLS and IPS type device can be considered a high quality screen panel.

Nosaka, cik daudz vietas ir planšetnieka "Cietajā diskā". Ja iekārtai nav pieejams atmiņas karšu paplašināšanas spraudnis, tad šis ir ļoti būtisks parametrs, kuru noteikti vajadzētu izvēlēties iegādes brīdī ar pietiekamu rezervi, jo bez paplašināšanas iespējām, ar šo apjomu nāksies sadzīvot visu iekārtas lietošanas laiku.

Vidusmēra filma aizņem ap 1GB vietas. Vidusmēra Android vai iOS spēle vai aplikācija aizņem ~100 Mb. Mūzikas un bilžu faili aizņem vidēji ap 5 Mb, jeb 0.05 Gb (par vienu failu).

This is a very important parameter because due to quite high resolution the tablet computer is quite demanding as to the CPU resources. Therefore, if you want to use several applications at once you should consider a possibility of buying a tablet with at least 2 core CPU.

It determines the type of CPU the particular tablet has. Currently several competing models of CPUs are available on the market.

NVIDIA Tegra - the processors of this series have good graphics and processing performance as well as quite good energy efficiency indices. In any case, this is a strong competitor.

SnapDragon - this processor is highly energy efficiency, however, from the point of view of capacity it is more suitable for smartphones.

AMD Fusion - this processor comes from the environment of portable computers, therefore it has excellent performance as regards both graphics and processing, still the architecture of this processor unfortunately is intended only for the use in the Windows, Linux and other desktop computer environments.

Atom - Intel mobile processor with average capacity indices. Similar to AMD Fusion, for the time being it can be used only with the operating systems of desktop computers.

Apple A5 - specialised processor developed by Apple that can be found in iPad tablet computers only. From the capacity point of view - among the leaders.

This is among the most important parameters in choosing the tablet computer.

iOS - the tablet computers manufactured by Apple are equipped with the iOS operating system that is very convenient and high-speed, however, this is a closed system where no special configurations and extensions are possible. However, within the iOS currently most applications (apps) are available. iOS is compatible with Apple cloud services for which a fee is charged in most cases.

Android is a free of charge operating system developed by Google, similar to the iOS, however with all the possibilities to make a lot of changes therein. Besides, the Android offers good compatibility with the Google free cloud services - Gmail, Picasa, Youtube, Maps, Google+, Contacts, Calendar etc. The number of the Andoid users is growing most rapidly, therefore, this is a very perspective operating system.

Windows - the classic Microsoft Windows system that allows to use the convenient .EXE applications in the tablet computer. It has to be admitted that currently they are better suited to desktop computers, therefore you should choose this operating system only in cases when there is a Windows application without which you cannot do.

Other (Bada, MeeGo, WebOS, BrewMP, Symbian) - currently on the market of the mobile operating systems also several exotic operating systems are available besides the above listed, still, you should take into account that the biggest fight over this market share is over, therefore you should take care if you choose an operating system which is not iOS, Windows or Android, because, contrary to the classic computers, in most tablet computers it is not possible to change the operating system after buying the tablet.

Although no tablet computer with the WiFi function has been seen we have included this parameter just for calming everybody down. Via WiFi the tablet computer can be connected to the Internet router to have the Internet access.

If there is no WiFi router and the Internet connection the sense of buying the tablet computer is quite questionable.

Bluetooth allows to connect a keyboard, headphones, microphone, printers and other devices supporting this technology without any wires.

This is an approximate indicator of the number of hours the device can operate with a fully charged battery pack, low CPU loading and the minimum screen brightness setting.

Depending on the loading and use possibilities - sound, wifi, 3G, copying of files, Bluetooth, etc., this index can change downwards very rapidly.
