How to choose a tablet computer?

To begin with, under the general name"Tablet PC" hides several types of devices. The most common are two: a tablet personal computer and an Internet tablet. Tablet PC - a full-fledged PC, only in the form factor of the tablet. If desired, you can connect a mouse and keyboard to it, turning it into a laptop. Such devices have hardware compatibility with IBM PC-computers. They are installed full-fledged OS - Windows, Mac OS X or Linux.

And the Internet tablet is, in fact, a hybridsmartphone and laptop. It has a compact size and is focused mainly on web surfing and working with web applications. Web-tablets are incompatible with IBM PC-computers. They are installed mobile operating systems (Google Android, Apple iOS, etc.) or systems that are targeted to Web applications and cloud services (Google Chrome OS, Jolicloud). In comparison with Tablet PCs, Internet tablets are less functional.

Most consumers have tablet computersare associated with Internet tablets, and asking how to choose a tablet computer, they mean web-tablets. This type of tablet devices is popular due to the relatively low cost, easy and convenient user interface, the orientation to work with the web and long battery life. Let's figure out how to choose a tablet computer.

Deciding to choose a tablet computer, manyfirst look at its appearance, while it is important first of all the filling, especially the processor. The processor in web-tablets is not as powerful as the usual PC, but there is no special power here. If you do not expect to load your tablet with something harder than surfing on the Internet, you will have enough CPU with a clock frequency of 600 MHz (but for accuracy it is better to take a margin of 800 MHz). If you are going to watch videos in high quality and play games, you need a processor with a frequency of 1 GHz or higher.

The second important point is memory. Under the memory can mean memory and built-in. RAM affects performance. You can choose a tablet computer with 1 GB of RAM - should be enough. The built-in memory determines how much information you can store. It all depends on your "greed", but most tablets are equipped with a slot for memory cards, so the amount of memory can always be increased.

Pay attention also to the establishedoperating system. Do not expect Windows to be familiar - there is no adequate version of Windows for tablet devices. On the iPad tablets, of course, there is an operating system from Apple - Apple iOS. But Apple devices are more expensive than analogues from other companies, and you will have to pay extra for many installed programs. For other brands, the most common option is Google Android, it's worth choosing the newer firmware. There are other OSes for web-tablets, but they are not so common.

Now you can look at the exterior,more precisely, to the screen. The diagonal of web-tablets can range from 4 to 11 inches, the most common options are 7 and 10 inches. If you are interested in compactness and low price, buy a tablet computer with a smaller diagonal. But if you want to choose a tablet, which will normally look like sites and video, it is worth choosing a tablet computer with a diagonal of 10 inches. The picture quality will be higher, and the interface elements will be larger, which will make the work easier.

Tablet computers are equipped with a touch screen. It is worth knowing that the types of touch screens are two - capacitive and resistive. Capacitive reacts even to a light touch of a finger, but do not respond to styluses (except special ones). Resistive in the first place are calculated exactly on the stylus, the fingers also respond, but the pressure will have to be strong. Here the main criterion is personal convenience.

Very important for a tablet computer timework from the battery. The more it is, the better, naturally. Of the two tablets with the same battery capacity and mode of use, the one with less diagonal will work longer. It is worth choosing a battery with a capacity of not less than 2000 mAh. Also the weight of the device is important, because you will carry it with you. For seven-inch tablets, the optimal weight is up to 300 g, for 10-inch plates - up to 700 g.

Because the web-based tablets are oriented firstthe queue to work on the Internet, they must be equipped with Wi-Fi and 3G adapters. To connect external devices (at least USB flash drives) you need USB connectors, for memory expansion - a slot for a memory card. Of the optional, but useful "lotion" can be called a built-in webcam, GSM receiver, Bluetooth, Ethernet connector and HDMI connector for connecting the monitor.

The material of the case is also important. It can be metal or plastic. Metal is more durable, such tablets do not scratch and do not creak, and look stylish. Models with a plastic casing are lighter, they better catch Wi-Fi. The quality of the plastic housing varies in different models. Whatever the case, for the tablet you need a cover!

As you can see, choosing a tablet computer is not as difficult as it seems. But to take care of the choice is not worth it, otherwise it may turn out that the purchased device will not meet your expectations.
