What is internal memory in a tablet. Increase the RAM on the tablet

Sooner or later, the owners of any equipment begin to be interested in the possibility of expanding RAM. Our article will tell you how to add RAM to the tablet on the example of Android OS and is it permissible.

How to add RAM to Android tablet and can it be done?

It seems quite obvious that the amount of physical memory in a device running a mobile operating system is a constant value that cannot be changed. However, it sometimes happens that an Android tablet starts to slow down and shows a deterioration in overall performance. In this case, we need to use special software that will create additional file paging random access memory. It is also recommended that you try to optimize running applications.

If you've tried previous versions, you'll find superior performance in running functions and applications in the most flexible and practical way for demanding users. This allows users to expand and improve the tablet's functionality. We know that like every other device in its class, this 7-inch tablet is powered by a 000-milliamp Li-ion battery.

We'll have to wait to get the exact time and see how far this tablet can go. We will be careful to bring you all the information from the fair in Barcelona and give you any details about its availability. The tablet can be immersed in water for half an hour at a depth of 5 meters, so you can take a shower or a bath without any problems without fear of damage. The main thing is that you need to make sure that all covers on the case are installed correctly.

If we decide to do optimization, we need to decide what kind of applications we are willing to donate. We go to "Applications" through the tablet settings and go to the section "Memory usage". Here we can visually see all open applications that load RAM, as well as information about memory usage and a general list of programs. If the indicator of free RAM is minimal (or even equal to 0), this means that we need to stop those running programs that we do not need right now. We click on the name of a specific application and select the appropriate item. If desired, we can also remove them altogether.

Compared to their predecessor, the stereo speakers move to the sides of the front panel case, and the slots are small, but the quality and volume are increased. The tablet also uses noise canceling technology. As a rule, compared to its predecessor, the tablet does not change in length and height, and only the thickness is reduced: from 9 to 4 mm.

The display is protected by scratch-resistant glass. The chipset itself remains the same, but with an increase in operating and graphics frequencies. But landmarks alone are not worth believing, since they do not always show the real picture. but last update the software corrects these shortcomings. As already mentioned, the tablet has gotten even thinner and its battery capacity hasn't changed. On the one hand, this is a plus, since usually work on the shape of the case leads to the fact that the compactness of the back side depends on the size of the battery.

Please note that after restarting the tablet, all suspended applications will start working again. We add that most of all RAM is consumed by "cloud" storages, navigator, email, games, play market and flashlight. This means that you need to start with them.

Now a few words about creating a swap file. It resides on a memory card or read-only memory. You can create such a file using an application like SWAPit RAM Expander. Such software will allow us to fully control the state of our memory and control the speed of the system. The program has a clear and user-friendly interface.

With continuous video playback, the tablet lasts over 8 hours. But again, for such a thin tablet, this camera is justified. Widgets can be a multitasking button, as well as multiple programs like calculator, browser, notes, etc. Can also be placed on the screen. Additional features include a standalone backup and restore application where you can choose where to copy and fully customize the list of backup data. You can also check the apps you want to keep.

So, we found out that the question of how to add RAM to the tablet is incorrect, since this cannot be done. Nevertheless, we can always increase the speed of work and optimize the system as a whole.

What else can be done in a situation where we cannot add RAM to the tablet, but want to improve the performance of Android?

Special attention is paid to the possibility of remote control of various technologies. The tablet can be easily used to control home appliances. Accessories You can purchase one of two docking stations separately, which is not included in the package. One is simpler and the other is a sound system, as its built-in speakers are very loud.

A control panel is available, allowing you to talk to it as a headset. There is also a cover to protect the device. For example, its weight is comparable to 8-inch models. In addition, the device has a dustproof housing against water and other tablets do not have this extra. Thus, we can expect more affordable tablets from the Japanese manufacturer, and the company's protection should also apply to other segments, not just flags. Attention is drawn not only to the unusual size, but above all to the unique combination of unique features.

If we wish, we can use an application called RAM Manager. We need it to optimize the operation of RAM, and it works with system version 2.1 and higher.

The program improves the performance of the system as a whole (it becomes noticeably faster). At the same time, an optimal balance is established between running applications that load memory and free memory. The program will also allow us to solve problems related to tablet slowness and multitasking.

Thanks to them, it works in many applications, as you could see from previous posts. Now it's time to take stock and complete the testing procedure. The workmanship and materials also can't say bad words. The latter material dominates because it covers the left bottom. On the other hand, the frame and built-in support, which are sensitive elements, affect the rigidity and stability of the structure. Everything does not bend or impress. Only strong pressure can cause minimal deflection of the back cover here and there.

In total, there are several operating modes for RAM Manager. For example, there are separate modes for running powerful games, for operating a system with more than 512 MB of RAM, etc. You can download the application from the Play Market.

Screen

Let's start with what you come across in the first place in the description of the tablet or when the tablet falls into your hands. This is his screen or display. As you probably noticed, the description of tablets contains the following parameters:

The system recognizes many atypical audio and video formats and supports them in their native screen resolution. You can read more about multimedia capabilities in the next article. In theory, every tablet should act as a content consumption tool.

Also, stop at a projector that, despite its small size, works well both at home and in the office. It's intuitive and gives off really good image quality. What can be useful and how does it work in practice?

There will be three different sizes and specifications on the market. A miniature projector, and the manufacturer claims the device can handle the problem as a multimedia center, among others. with high quality speakers and high resolution screens. The manufacturer supplied its products with a single 8MPx camera.

Resolution

Matrix type: AMOLED, IPS, etc.

Viewing angles

Protective covering

Let's dwell on each of them separately.

The size... Tablet screens are traditionally measured diagonally, and the size itself is measured in inches. Everything here is simple and clear.

Tablet with big screen (9.7 - 10.1 inches and more) is suitable for those who are going to work with documents, read books, communicate on the Internet. Such tablets are more likely home or office devices - they are inconvenient to carry with you all the time. But reading a book or watching a movie on the couch is most enjoyable on a device with a large screen.

The device will go on sale in early November this year and will cost $ 499. The simplest answer to this question is that flash memory is like hDD on the tablet. The hard drive counterpart is good because flash memory has the same function in a tablet as a drive on a computer. We can save required files, install games and applications, and when you no longer need them, delete them from memory. Of course, the more memory you have, the more games and applications we will consider.

Memory tablet computer differs from the technology used. While the laptop and its components are actually knocked out, we will find the box in the case, but in the case of a round tablet such as a disc, we will not. There are tablet models on the market with very different capabilities.

More compact tablets, with a screen of 7 - 8 inches diagonally, are ideal for those who prefer (or have to) do all this outside the home - in the subway, train compartment, on vacation or business trip. The seven-inch tablet can be placed in a trouser pocket or a small handbag if desired.

Resolution... Screen resolution is measured in dots or pixels. What are dots or pixels? The image on the tablet screen, like a mosaic, is built from separate elements - pixels, each of which (roughly speaking) can change its color and brightness. And so, the more of these dots on the tablet screen, the clearer the image will be. Try, for example, making the letter A out of four dots. You won't succeed. But with the help of eight points, you can already depict something similar to a letter.

How much memory do you need?

Which one should you consider? The tablets are different from their users. Some buy a device to play the latest games for hours, others think of tablets in terms of work tools, and others only want to use car navigation or reading e-books. Before we look at how much flash storage capacity is for us, we need to answer the question of how we intend to use the tablet.

If your tablet is designed to store music and e-book and web browsing, we may be less happy with the device. Game fans or professional designers will need a lot more space. A tablet suitable for such people should have as much memory as possible to install multiple games or create large projects.

So, when you read that the screen of a tablet, for example, has a resolution of 1200 x 800 pixels, that means that the image on it consists of 800 lines, each of which contains 1200 points.

In principle, the resolution given as an example is quite enough, in order to work with the tablet comfortably, and the text on its screen looked clear. Of course, the larger the screen size, the larger the individual pixel size will be (at the same resolution). Therefore, to make the picture look clearer, the resolution of the ten-inch screen must be larger than the resolution of the seven-inch screen.

The amount of flash memory is important not only because of the number of files we can handle on the device, but also because of the speed of the tablet. If the space is too small, the device may slow down significantly. In order to have a clear understanding of what flash memory is and to make the right purchasing decision, we cannot confuse different types of memory. What are the different types?

It's called that. Operating memory, so the space on which installed applications can "work" and save temporary files. Memory cards can also serve as permanent memory expansion. Mobile devices accompany us every day, so no one is surprised that they also actively use children. According to the site of the specialist mobile deviceThere are several reasons why a tablet might be the best solution for students and parents.

Matrix type... Here you will come across such incomprehensible terms as AMOLED, IPS, TN, MVA, Pls and so on, which describe nothing more than the principle of operation of the tablet screen. We will not go into details, and for now it is enough for you to remember that the first two types - AMOLED and IPS today have the best properties, such as brightness, contrast, color rendition, and viewing angles.

The extremely high portability combined with the high level of functionality and lower costs than ever makes it really worth considering purchasing this device in preparation for school. Tablet site experts recommend paying attention to a few things that a modern student tablet should consider.

High quality student tablet

It is the screen that is the element that we look at first. Depending on your individual needs, you can choose a different diagonal screen. according to tablet computer experts, and 1 inch. screens. When choosing a tablet for a student, it is suggested to consider what screen technology the manufacturer is using.

By the way, what is viewing angles? Everything is simple here. If you, holding the tablet perpendicular to your face, begin to tip it back or turn it to the side, you will notice that at a certain moment the image on it begins to lose color, brightness and clarity. So - the viewing angle, this is the angle, when you turn it, the image on the tablet screen does not lose its quality.

Protective covering.

In order to prevent the tablet screen from being scratched by contact with hard objects, for example with keys in the bag and no chips left on it from impacts, a protective coating is applied to it. The best protective coating available today is Corning Gorilla Glass. Whether your tablet has such a coating, you can find out either in its description or on the Corning website.

CPU

The processor is the brain of the tablet, which controls all of its work. And, like mobile phone processors, a tablet processor is a much more complex device than, for example, a desktop processor. It is even more correct to call it not a processor, but a system-on-a-chip (or SoC in English), which contains a conventional processor, a video processor, which is responsible for making the "movie spinning" and games "running without brakes", as well as contains a set of auxiliary things, such as, for example, providing an image output to the TV.

Most modern processors are multi-core. What does it mean? Roughly speaking, each core is a separate processor that takes over part of common work... Therefore, usually, a dual-core processor is faster than a single-core, and a quad-core processor is faster than a dual-core.

The next parameter is the clock or operating frequency of the processor. Today it is measured in gigahertz (abbreviated as GHz). We will not go into physics - it is enough just to remember that the higher the operating frequency, the faster the processor works. And the speed of the tablet itself depends on its speed.

RAM

Random access memory or RAM (from: random access memory) is, figuratively speaking, the place where programs are located after they start, and where they store their temporary data. The size or amount of RAM is measured in megabytes or gigabytes. Today's tablets have a storage capacity of one to two gigabytes. Rarely, but you can still find a tablet with 512 megabytes or half a gigabyte of memory.

In practice, today for normal operation, one gigabyte (1 GB) of memory is enough for an ordinary tablet, and its larger volume will not in any way affect the improvement of its work.

Exceptions are tablets with operating system Windows, which traditionally feels better the more RAM it has at its disposal.

Also, additional memory may be required for such tablets, which the manufacturer has equipped with many additional functions. Example - samsung tablets, families Galaxy Notethat have a digital pen and a set of applications for working with it.

Built-in memory

Built-in, or flash memory, is the place where applications, documents, music, books, films and other things installed on the tablet are stored, for which we actually bought our tablet. And the more internal memory a tablet has, the better, of course.

However, there is one caveat here. If the tablet has a slot (space) for installing a memory card, then there is usually no point in overpaying for a tablet model with a large amount of internal memory, as, for example, an 8 gigabyte memory card costs several times cheaper than the price difference 8 and a 16GB version of the same tablet.

But there are exceptions here too - google tablets families and tablets Apple iPadmanufacturers of which fundamentally do not allow their users to use memory cards to increase the amount of internal memory of their devices.

So, we figured out the main parameters, move on to the additional ones.

Adapters and ports

Adapters and ports are how the tablet communicates with the outside world, with which it can be connected to the Internet and other devices.

Wi-Fi adapter is an adapter for connecting to wireless networks and getting Internet access in public places (cafes, hotels, airports) and at home. Absolutely all modern tablets are equipped with this adapter.

Bluetooth adapter known to us by mobile phones... It is too wireless adapter, with which you can exchange photos and other information, connect external devices such as Bluetooth keyboards, mice, headphones, stereo headsets, or even such specific things as diagnostic adapters with which you can check the condition of your car.

GPS receiver is designed so that using signals from special satellites, the tablet can determine its coordinates, and also with the help of appropriate programs can build routes and help you navigate along them, displaying your location on a map of the area.

3 G or LTE modem... What if you are on the go or you cannot connect to the Internet via Wi-Fi? Will come to the rescue mobile Internet, which is provided by cellular operators, and to which you can connect if you have an appropriate modem in your tablet. What is the difference between 3G and LTE? This is a type of network, and LTE networksas more modern ones allow you to transfer data at a higher speed than 3G networks.

HDMI exit. Using this port, you can connect a TV or external monitor, on which you can watch the video or which you can display the image of the game running on the tablet.

Memory card slot... As already mentioned, with this slot you can expand the internal memory (flash memory) of the tablet, which stores photos, videos, documents and programs and games installed on the tablet.

Ethernetport. This connector can be found in some Chinese Android tablets and many Windows tablets. It is designed to connect to computer networks and the Internet using a special cable.

USBport. Everyone probably knows about him. But if you are not familiar with the USB port, then let me remind you that you can use it to connect hard drives, flash drives (or flash drives), an external keyboard, mouse, 3G modems and other devices to your tablet. Usually, a micro-USB connector is installed in tablets, and in order to connect the above devices to it, you will need a micro-USB adapter to a "regular", full-size USB port.

Sometimes, the micro-USB connector can also act as a connection port charger... This is very convenient, because in this case, you can use AC adapters from other devices, for example, phones, to recharge the tablet battery, and also charge the battery by connecting the tablet to a personal computer.

Cameras

Many tablets are equipped with two cameras. The front camera is typically used as a webcam for online chatting, while the rear camera is used for taking photos and videos. Camera quality is usually measured in megapixels (millions of pixels). You already read about pixels when you got to know the tablet screen. An image in a photograph or a single frame of a video also consists of pixels. And you already understood that the more of these pixels, the better the image will be.

However, it is worth considering that, for example, an eight-megapixel tablet camera will shoot worse than an eight-megapixel camera. Why? It's all about the lens and the size of the camera matrix on which these pixels are located. A small tablet camera lens does its job worse than a large camera lens, and a small matrix receives less light and, due to its design, produces a more noisy (remember that multi-colored "dust" that is not visible in some photos) image.

Operating system

There are currently four types of tablets on the market. These are tablets running an operating room android systems, Apple tablets with the iOS operating system, and tablets with two versions of the Windows operating system: "regular" Windows (8) and Windows RT.

Android tablets are best suited for those who want complete creative freedom. This operating system allows you to change its appearance and add new features that are not available in the factory (custom) version.

Operating system tablets iOS will appeal to those who just need an easy-to-use gadget. You won't be able to experiment with appearance and the functionality of its operating system, but Apple tablets boast a huge number of applications and games created specifically for this type of device, which Android tablets still lack (but this is a temporary advantage that will soon disappear).

Windows tablets are best used for professional purposes - these devices are best suited for tasks such as working with documents, spreadsheets, presentations and other professional tasks.

It is worth, however, take into account that tablets with a regular version of Windows, by virtue of their design, have a shorter operating time without recharging the battery than Android tablets and Apple tablets, and tablets with OS (operating system) Windows RT cannot run programs and games created for others windows versions... Currently, the choice of applications for Windows RT tablets is very limited and this should be considered when purchasing them.

Construction (body material, moisture protection, etc.).

Until now, we have been talking about stuffing tablets. Now let's focus on its shell or device case. The tablet case can be made of metal or plastic. In the first case, you will get a more reliable and shock-resistant device. The plastic case is usually nicer to the touch, but this is a matter of personal preference.

In addition, some tablets have a case that protects the device from external hazards such as moisture and dust. For example, Sony Xperia Tablet S and Fujitsu Arrows Tab tablets can boast a waterproof case.

These are all the basic parameters you need to know about when choosing a tablet. As you've probably noticed, one principle works almost everywhere - the more the better. The more megapixels, the better screen and a tablet camera, more cores and a higher processor frequency - more work speed. More memory, more ports and adapters - more ease of use. The only exceptions are screen size and tablet weight. You choose the size of the screen to your taste, and the less weight the tablet - the more convenient it is to handle and transport.
