What is a computer tablet? Decide on display size
These days, tablet computers are no longer new. They have thoroughly gained a foothold in the electronics market and continue to gain popularity among users, primarily due to such an important advantage as compactness. Manufacturers (and this is not only famous brands) are releasing more and more new models of tablets, as they are popularly called. To navigate your choice, you need to take into account many criteria so as not to get confused when purchasing and not to be upset if your choice does not meet your expectations.
What is a tablet computer? First of all, it should be noted that its main difference from other computers is the touch screen, with which the tablet is controlled. That is, the tablet owner will not need a mouse or keyboard. Technological progress does not stand still and now models are already appearing that can be controlled using several fingers (multi-touch gestures).
Of course, it’s hard to disagree with the fact that a tablet’s capabilities are inferior to a regular desktop computer or laptop. However, it can also be useful:
- 1. If you need to browse pages and websites on the Internet (web surfing).
- 2. If you need to work with programs and applications that require an Internet connection.
- 3. If you are reading e-books.
- 4. If you are browsing graphic files, photo albums and galleries, etc.
- 5. If you want to listen to music or watch a video, the tablet plays multimedia files.
- 6. If you love electronic games.
- 7. If you use by email.
- 8. If you want to be always available for communication, for example in ICQ, Skype, M-agent and other similar chat programs.
- 9. If you use IP telephony and video communication.
- 10. If you not only view, but also edit electronic documents, graphic and multimedia files.
How to choose a tablet computer?
Before you make a choice, you need to know that a tablet computer refers to several types of devices. The most common options are two: tablet personal computer and an internet tablet. The first is practically full-fledged computer, that is, if necessary, you can connect a keyboard and mouse to it, and it will be no different from a laptop. In addition, a familiar, full-fledged operating system is installed on the tablet personal computer: Windows, Mac OS X or Linux.
And the second is nothing more than a symbiosis of a smartphone and a laptop. It is compact and designed primarily for viewing websites and working with various web applications. Unlike the former, it is not compatible with IBM PC computers. Operating systems installed on Internet tablets are the same as on mobile devices: Android, Apple iOS or other systems that are suitable for working with web applications: Google Chrome OS, Jolicloud.
Naturally, Internet tablets are inferior in functionality to tablet personal computers. As a rule, users perceive a tablet computer as an Internet tablet. And if they are wondering how to choose a tablet computer, then they have in mind the second option. The popularity of tablets is growing for several reasons: because of their low cost, convenient and uncomplicated interface, because of their focus on working on the Internet, and also because of the possibility of long-term battery life.
Now let’s figure out what parameters you need to consider when choosing a tablet computer.
CPU.
Quite often, when choosing a tablet, people give the most great value his appearance, but the most important thing in a computer is the processor. It is clear that a tablet computer’s processor is not as powerful as a desktop or laptop computer, but it does not need more power. If you plan to use it for web surfing, then a processor with clock frequency 600 MHz, but it would still be nice to have some reserve, for example, 800 MHz. But if you want to watch video files in good quality or play video games, you will need a processor with at least one gigahertz speed. However, the more, the better.
It should be noted that the processors installed on tablets consume less energy than on conventional PCs. It is best to purchase a tablet with a new generation processor, since the newer the processor generation, the more current the operating system it supports. That is, the choice of processor for a tablet should be based on its newness and frequency.
Memory.
This is the second important selection criterion. We are now talking about two types of memory: RAM and built-in. Random access memory (RAM) determines the speed of your computer and the number of applications you can work with simultaneously. So: 512 MB is minimum quantity memory, with which the tablet will work, but slowly and sadly; from 768MB to 1GB – the amount of memory for trouble-free work with several programs at the same time; more than 1GB - the amount of memory with which your tablet will cope with tasks that require large resources, for example, new generation video games. But, as a rule, one gigabyte is enough.
Built-in memory is the memory of the computer itself, that is, it is the determining factor in the amount of information that you can store on it. This indicator is also, in general, the higher the better. But it’s worth clarifying that the tablets have a slot for an additional memory card, so if you made a mistake when purchasing, then this matter can be corrected, the memory capacity can be increased. Modern tablet computers accept memory cards up to 64GB inclusive.
Operating system.
The operating system installed on the device is also sufficient important point. You won't find the Windows we're all familiar with here. On tablets iPad computers installed, of course, operating room Apple system iOS, which has a huge disadvantage, namely: everything Apple devices the cost is much more expensive than other similar devices, in addition, you will have to pay extra for many of the programs that you will need to install. On the bulk tablet computers operating system installed Google Android, also used on various mobile devices. When choosing it, try to purchase the version with the most new firmware.
There are a number of operating systems for tablets, but they are much less common. This is a Windows RT OS related to Windows family 8, created specifically for tablets. And Windows 8 itself, the most popular operating system for desktop computers and laptops. The listed operating systems differ in the interface and organization of work with the tablet.
Screen size and resolution.
After all of the above, you can pay attention to the appearance, that is, the screen. Tablets are available with screens ranging from 4 to 11 inches, but the most popular are from 7 to 10 inches. The larger the diagonal screen, the more convenient it is to work with it, that is, the image quality will be better and the interface elements will be larger. However, as the screen diagonal increases, the size of the tablet also increases. If you do not plan to carry it with you all the time, then for you optimal choice there will be a diagonal of 9 to 10 inches. For those who need to keep a tablet at hand at all times, it is better to choose a model with a screen diagonal of 5 to 7 inches. Such a device is not only compact, but also much cheaper in price.
The next screen parameter is its resolution, that is, the number of vertical and horizontal dots, of which, in fact, it consists. These dots are called pixels, and screen resolution is measured in pixels. For example, if the documentation states that the tablet screen is 800x600, this means that 800 pixels fit vertically and 600 horizontally. The higher this value, the more high quality image can be obtained, the easier it will be to read small text.
Screen size and resolution need to be considered simultaneously. For example, if the screen diagonal is 7 inches and its resolution is 800x600, then this combination will be comfortable for work, but if the diagonal is larger at the same resolution, the image will be somewhat blurry and the text less readable. One more point that I would like to mention: the higher the resolution of the tablet’s screen, the less time it can work without recharging.
Touch screen.
As mentioned above, all tablets have a touch screen, which comes in two types: capacitive and resistive. Capacitive touchscreens are very sensitive and respond to light finger touches, but do not respond to stylus touches. Resistive touch screens, on the contrary, respond to styluses, and if you use your finger, then the pressure on the screen should be decent. The choice of screen here depends on how you prefer to work with the tablet: with your finger or a stylus.
Autonomous work.
It is clear that battery life, that is, battery life, is also an important indicator for a tablet, because, as a rule, you take it with you. If we compare two tablets with equal battery capacity, then with the same operating mode, the one with a smaller diagonal screen will last longer. Opt for a battery with a capacity of 2000 mAh or more. The weight of your tablet also matters since it is a portable device. For tablets with a screen diagonal of 7 inches, the optimal weight is up to 300 g, and for 10 inches - up to 700 g.
Additional devices.
Since a tablet computer is most often used to surf the Internet, it must have Wi-Fi and 3G adapters. To be able to connect external devices, For example, USB flash drives, it should have USB connectors for them, and to increase memory - a slot for a memory card. There are other useful devices, maybe not so important, but sometimes necessary, such as a webcam, GSM receiver, Bluetooth, Ethernet connector and HDMI connector for connecting a monitor.
Frame.
Pay attention to the material from which the tablet body is made. If the case is metal, then it is more durable, there are fewer scratches on it, and it looks solid. But models with a plastic body weigh less, and Wi-Fi works better in them. Actually, the plastic is also different, depending on the model. Regardless of the case material, the tablet needs a case to prevent damage to the screen.

About a difficult breakup with a girl
Good day everyone) Now I’m going to complain. I dated a girl for 5 years since the 9th grade of school, she was my first. They loved each other very much. They wanted to start a family. But I always...
On at the moment Tablets are used for different purposes, some surf the Internet during long subway rides, and others read books and watch movies when they are in a cafe or sitting in line. I am very pleased that the cost has dropped significantly; if you wish, you can find high-quality model for 6,000 rubles, however, it was developed in China, but this in no way affects the quality. The tablet can also be used for work when there is no access to a computer, since all office applications run on it without problems. But before we talk about choosing a model, you need to decide exactly what it is and what it is used for in most cases.
So, the article will consist of the following points:
What is a tablet
Previously, people bought phones with large touch screen, since with their help you can conveniently surf the Internet and watch photos and films. A tablet is something similar to a smartphone, but its screen is much larger and the capabilities are the same as a modern computer. There are ultra-mobile and computer tablets, and there are also very original models that are equipped with a docking station. It's a simple, small-sized computer that has a touch screen and a keyboard, but it detaches very easily and simply, turning it into a full-fledged tablet.The most common tablets are classified as internet tablets, or, more simply, tablets for the Internet. This simple model tablet computer without complex functions, which was created exclusively for working on the Internet, this is what you see most often in cafes where there is access to Wi-Fi. Of course, you can also read books and watch movies in high quality through them, but these capabilities are classified as additional functions. The design of this tablet resembles newest smartphone with an incredibly large display, however, the display supports many functions and is made of very high quality, almost all displays have multi-touch function and gesture control. If you are not satisfied touch control, you can always purchase a mouse and keyboard from USB connection, and their cost is very low.
Tablets have similarities with smartphones, for example, in the operating system. Most models run on only three OS: Android is the most common system, iOS for models from Apple, Windows 8 or RT for many models, for example, from Asus.
How to choose a tablet computer
It doesn't matter whether you want to give a tablet to your friend or buy it for personal use, in any case, you should understand the characteristics so as not to waste your money. Almost all models are divided into two main categories - those that have a screen larger than 7 inches and smaller. Small models are ideal for daily use because they do not take up much space and you can take them to the country or on a trip. Through this tablet you can listen to your favorite songs, read books and watch movies. The screen size is quite comfortable for these purposes - 800x480 pixels.Models with big screen They look very attractive, but they also cost much more. They are much more convenient, because there can be many small icons on the screen, and while working on the Internet you need to click on one of them. The picture quality is also much higher, making photos and movies much more enjoyable to watch. The smallest screen resolution is 1024x600 pixels.
But it's not just the screen size; there are other nuances that you need to pay attention to. The operating time of the device is one of the decisive factors when choosing. Battery operation depends on its capacity and power consumption. For example, if the battery has a capacity of 1000 mAh, then you will not be able to watch movies or play games at low specifications even for 2 hours. Models with a battery capacity of 2000 mAh or more are much preferable. You also need to take into account that the same manufacturer tricks apply to tablets as to other devices. They indicate a very long operating time of the device, because testing is carried out in comfortable working conditions. When purchasing, you need to reduce the time stated by the manufacturer by about 30%. If both models have the same characteristics, then the choice should be given to the one that works longer.
Next, check out the weight of the device, largely this characteristic depends on the duration of the tablet computer's battery life. The weight increases if the battery capacity is very high. If the screen has a diagonal of 7 inches, then a weight of 300 grams is preferable, if larger - 700 grams.
After that take a look at software characteristics, including the tablet operating system. In stores you will find tablet computers with iOS, Windows and Android, but what is the difference between them? Firstly, each model has standard set programs through which you can listen to music, watch movies and access the Internet. If you have your own goals for using the device, you need to download additional programs. Of course, the choice of programs depends on operating system. The most inconvenient and impractical option is a tablet with iOS, since everyone knows about Apple Store and high prices for programs. Choose a model with Android OS because... Android store Market you can purchase a lot of programs for every taste, and many of them are completely free. Installation also does not take much time - download the file and install in a few seconds. For those who are used to using Windows, this OS will be very convenient, because the differences between a tablet and computer version are missing.
Then look at the tablet's performance. Everything here is the same as with laptops and computers, of course, the characteristics of the tablet are inferior to conventional PCs. Be sure to look at the following characteristics:
- Processor (frequency) – affects video viewing; it is advisable to choose a model with a frequency of at least 1000 MHz for watching HD movies. If you watch movies in low or medium quality, then 600 MHz power is quite enough.
- RAM (volume) - just like a computer, it affects the ability to run several programs. The more memory the better, don’t skimp on this feature.
- Information storage (capacity) – if you want to store a lot of files on your tablet, then you need to choose a model with a large capacity. But do not forget that the cost of flash drives has now dropped significantly, so it is more convenient to buy several additional drives than to spend money on a model with a large storage capacity and an inflated price.
Well, at the very end, you can choose a case for the tablet, because you can damage it without special problems. The case protects against unpleasant scratches and cracks on the screen, since the device is very fragile and any awkward movement can lead to damage.
Which tablet to choose in 2013
What models are the most popular in the coming year? Below we will talk about two tablets that are leading the market at the moment.
iPad with a new Retina screen (cost at least 20,000 rubles)
Device characteristics: 9.7 diagonal and screen Retina IPS, modern processor Apple A6X, 42.5 WH battery and Apple iOS operating system. We can openly say that almost everyone wants to own Apple products, but due to the high cost, many deny themselves it. There is an updated model of this tablet with 4G support, but its cost is much higher. We have listed the most common characteristics of the iPad, there are different models, somewhere they are worse, and somewhere better, and the cost is also very different. New model called iPad 4 has Apple processor A6X and newest Retina screen.
Google Nexus 7 with 3G support (cost at least 12,000 rubles)
This model is cheap in the US, so you're very lucky if you can order it through EBAY or ask a friend to bring it. Tablet characteristics: gigabyte of RAM, NVIDIA Tegra 3, 7 IPS screen, 4,325 mAh battery and operating system Android system JB. The tablet is especially relevant among fans of the Android OS, since it is the latest development that brings together all the best. If you are confused by the price and cannot order a model from the USA, you can choose budget option without 3G, the cost of which does not exceed 9,000 rubles.
Laptop or tablet, which to choose?
Many people are debating what is more practical: a tablet or a laptop? Below we will talk about the pros and cons of these devices.Entering information on a laptop and tablet
You can immediately notice that there is no keyboard on the tablet, unlike a laptop. Not everyone is used to entering information using touch keyboard, so it will take longer. Of course, this is much more practical and convenient if you need to drag files from one place to another, but if you want to communicate with friends through sending services instant messages– you will spend too much time, which will cause discomfort. You will be typing slowly while your interlocutor has already sent several messages. That is why sooner or later the question arises about choosing a keyboard for a tablet, but will it be convenient for you if you carry an additional keyboard with you? If you often communicate on the Internet or your work is somehow related to texts, you need to choose a laptop.
Size difference
A laptop is much larger than a tablet, so people who just want to watch movies while long trip prefer a tablet. The weight and size of the tablet is the same as that of a regular book - no more than a kilogram. At the same time, laptops are several times heavier and larger; if you look closely at the smallest laptops, you will notice that the weight is more than 2 kilograms and the size is slightly larger than that of the iPad 2. All this is due to the keyboard and the latest video cards with a cooling system, it takes up a lot of space and increases the size of the device. Therefore, for those who often fly by plane or travel by train, it is much more profitable to buy a tablet, because it practically does not take up space in your bag and is very easy to use.
Tablet and laptop operating time
Due to the fact that the tablet does not consume much energy, it has small size. Installed on any laptop modern video card, processor, RAM and many other things that increase energy consumption. Without additional charging The tablet can last about 10 hours, which is twice as long as a laptop. Regular laptop with the most standard characteristics it works from 3 to 5 hours, of course, the most best models can work for 8 hours, but this is less than a tablet, and the cost of such a laptop is much higher. If you want to watch movies and play games all day long, for example during a long train ride, then it is better to prefer a tablet.
Quality software
The software capabilities of a tablet and a laptop are very different, and for many this can be a deciding factor during the purchase. For example, tablet models with Windows 7 can perform the same functions as laptops with the same operating system, although the operating speed is noticeably lower. But you can still use the same programs, the discomfort will only arise in the speed of downloading applications and the quality of work. Models with iOS and Android have other programs that can easily replace the same software installed on the laptop. But due to the reduced performance and the lack of many features - the quality of the programs is lower, you still have to accept the fact that this is a tablet and it cannot work like a laptop. If you often work in office applications and you need programs to do your work, you need to buy a laptop, since a tablet is much inferior to it.
Which tariff to choose for a tablet
How to save on the Internet when using a tablet? If you like to just go to websites and read articles, watch the weather forecast and check exchange rates, then best option- “Unlim” from Megafon. You will not spend money on extra traffic, since you are allocated 30 megabytes per day, and the cost is only 5 rubles (150 rubles per month). At the same time, the speed is very high, so you will not experience any discomfort when loading pages.
But if you want more traffic, then you can take a closer look at the tariff with an allocation of 100 megabytes per day. The cost is approximately 350 rubles per month of Internet use; when the traffic is exhausted, the speed will drop to 64 kB.
If you are used to the Internet that is connected to your home, then you need to take a closer look at unlimited tariffs. With their help, you can download games, movies, music, communicate with friends on forums and social networks, and even watch movies in DVD quality. This tariff is available to all residents of Russia, but has not yet been connected to far east. It is provided by Beeline and it is called “iPad unlimited internet" There are several tariffs:
- Unlimited Internet 400 – speed no higher than 256 kbps and a monthly fee of 400 rubles.
- Unlimited Internet 600 – speed no higher than 512 kbps and a monthly fee of 600 rubles.
- Unlimited Internet VIP - speed no higher than 2048 kbit and monthly fee of 1000 rubles.
Hello, dear readers of the Start-Luck blog. All that glitters is not gold. Just like not all technological products that many people use are useful. Do we need to look far for examples? Surely everyone can name two or three products that, even though they are used everywhere, you would not buy for yourself.
“A spinner, a toaster, a sandwich maker - even if others use them and call them at least 1000 times useful, personally they are not suitable for me. I wouldn't spend even a penny on them." However, today we will not talk about them.
In this article I want to tell you about what tablets are for. I will tell you why and for whom they are needed, whether the tablet is suitable for working on the Internet, and much more that will definitely be useful to you. By the end of the publication, you will be able to decide whether you really need a tablet or whether it is better to save yourself from unnecessary expenses.
What is a tablet really?
To be honest, I've owned a variety of tablets ranging from the most expensive to the incredibly cheap. Despite this, don’t expect me to start talking about their necessity, importance and usefulness right now. I tend to admit my mistakes and try to be objective.
For starters. What is a tablet? This big smartphone, the main task of which is not making calls, but all other functions - games, applications, e-reader, and so on. You can view news and publish your own photos.
Through a tablet, as a rule, you can also communicate via telephony, but you can also use Skype to communicate with friends and acquaintances via the Internet using a camera. The main thing is that there is a slot for a SIM card inside the device. Pay attention to this when choosing a gadget, otherwise you will only be able to connect to the Internet via Wi-Fi. This is extremely inconvenient. The tablet is no longer 100% mobile.
Samsung tablets are considered very good. Please note Galaxy Tab A 7.0″ 8Gb . It is not very big, but comfortable and functional. Naturally with a SIM card slot.
Alternative to PC and smartphone
If you're thinking about buying a tablet to use instead of a phone, as I once did, I'll tell you right away that it's not a good idea.
Tablet is still bigger regular phone, carrying it with you is not very convenient. After a week or two, you will get tired of it and either buy yourself a regular smartphone, or stop constantly taking your tablet with you. In my opinion, this gadget is not suitable as an alternative to a telephone.
There are also those who want to use a tablet as an alternative to a laptop. For example, at one time I wanted to write articles, taking with me not a heavy PC, but a small gadget. I think many people have thought about this too. And again, the tablet itself does not perform well in this matter.
The on-screen keyboard does not allow you to type quickly, your work slows down, and you begin to lose your temper. Fortunately, it won’t be a problem to order yourself wireless keyboard for tablet. It turns the gadget into a quite decent small laptop that is convenient to carry with you. For copywriters who like to work outside the home, this is a good solution.
However, you should not forget about the specifics of the tablet. There are versions special programs for PCs that will not install on Android or iOS. You will have to use which ones to install instead of the usual Office, Photoshop, and so on.
A tablet cannot 100 percent be called a good alternative to a computer. This is an independent thing that is needed if you need, excuse the tautology, a tablet.
When and who needs a tablet?
If you have small children, then a tablet is an irreplaceable thing. You can turn on cartoons and all sorts of videos from YouTube, but at the same time you don’t have to worry too much about the baby’s eyesight, or the fact that he will somehow break something in it.
On a laptop, a child finds a thousand buttons that are so wonderful to press. This doesn't happen with a tablet. By the age when the baby begins to figure out where and why to press, his interest in destruction fades a little. He already understands that this thing is quite important and should not be broken.
How to choose a tablet for a child? I recommend paying attention to the exhibits on low price, since the risk of breakdown still exists, because we're talking about about the child. Another important point - big screen. By the way, there are special tablets for children, for example, Turbo MonsterPad 7 .
When is a tablet necessary for an adult? If you can't live without a phone. If you often play games and use applications, you need a tablet. If you like to watch movies or read books from a mobile device, consider purchasing this gadget. The screen is much larger, and therefore it will be more convenient for you to use it. This item will not disappoint you.
It may also be suitable for work if you show some presentations, often work with email via phone, and so on. There is a whole layer of people who really need a tablet. To me lately I really like Lenovo, so I can offer them to you Tab 3 Plus for 16,500. A very profitable purchase.
I hope this article was helpful to you. Don't forget to subscribe to the blog newsletter and group Start-Luck VKontakte . See you again and good luck in your endeavors.

What are Internet tablets
All other tablets, which we are accustomed to calling specialists, are classified as Internet tablets. These tablets have gained the greatest popularity among buyers, due to their lower price, longer battery life, compactness and lightness. But the main thing is the presence of an operating system that is more tailored to the user’s needs, specifically created for mobile devices.
The tablet craze began with the introduction of the tablet computer in 2010. Apple iPad. Distinctive feature Devices of this class (Internet tablets) are incompatible with the IBM PC and the mobile operating systems installed on them, the same ones installed on smartphones.
In view of the above, Internet tablets are characterized by less functionality compared to IBM PC-compatible devices, but their strong point is the possibility of a variety of ways wireless internet connection.

In addition, specially for such tablets, various useful applications, games.
What to look for when buying a tablet

Before buying a tablet, you need to decide on such characteristics as: the most convenient screen size and its resolution. Screen resolution, just like for any other screen, is determined by the number of displayed pixels horizontally and vertically of the screen. The quality of the picture on the tablet screen directly depends on this indicator: the higher the resolution, the clearer the picture.
As with any computer, the most important components on the functioning of which determine the speed and reliability of the device are the processor and RAM. No less important characteristic device is the amount of its built-in memory, as well as the ability to connect external card memory. The rule here is that the higher the indicator value, the better.
A plus for tablets is the presence maximum quantity ways wireless connection to the Internet. Required for tablet availability of Wi-Fi and 3G, which allow you to connect to the Internet where there is a Wi-Fi source and where there is a 3G cellular network.
Thus, the tablet devices we are familiar with belong to the class of Internet tablets, which differ from tablet computers proper in their lower price and the presence of a special mobile operating system. And when choosing which tablet is better to buy, you need to proceed not only from its price, but also take into account the quality and functionality of the device.
