If your computer is slow, you have problems using programs or watching videos, it makes sense to check your computer's performance. The performance index is used by the Windows 7 operating system to visually and understandably evaluate its own performance. The higher it is, the faster and more powerful the computer, the more complex programs and games it can handle.
What is a performance index
Windows Experience Index (WEI) is a Windows operating system service that allows you to test your computer's performance.
How to find out the performance index
There are several ways to find out your performance index. Let's look at the two simplest ones.
Via "My Computer"
Via the Start menu
As you can see, both methods are quite simple and do not take much time.
What categories are presented in the table
The Performance Index table includes five components:
What do the numbers mean?
The WEI of a computer is determined by the lowest score. The maximum score in Windows 7–7.9, the minimum is 1.0. Let's look at the Performance Index indicators using the example of graphics evaluation.
Table: Performance Index scores and computer functions that correspond to them
Ways to improve computer performance
For a modern desktop computer, the normal performance index starts at 5.0. Please note that the latest drivers must be installed on graphics devices, otherwise the performance may be underestimated.
Most often, the WEI will be 5.9 when using an HDD (hard drive), even if the scores in other categories are significantly higher. This is due to the low access speed of the main hard drive. When replacing an HDD with a solid-state SSD, the HDD performance score rises to 7.9 and becomes the highest in the category table. Using solid state drives significantly improves the overall performance of Windows.
Low graphics performance may be the result of missing graphics drivers or insufficient graphics card performance. To fix a software problem, you should download drivers from the official website of the manufacturer that produced the graphics equipment for your computer. If the drivers are installed correctly, replacing the video card with a more powerful one will help improve the performance index.
Additionally, you can increase your computer's performance by doing the following:

What to do if performance reviews aren't working
It happens that the procedure for calculating the performance index ends in an error. This error can be caused by either software or hardware problems.
Software problems:
- the presence of viruses, Trojans, malware in the system;
- disk errors;
- path or registry errors.
Hardware problems include the failure or incorrect operation of one of the elements.
Software errors are resolved in the following way:
- scanning your computer with antivirus (Malwarebytes), as well as other antivirus utilities;
- checking the hard drive for errors;
- scanning the system for damaged components. To do this, open a command prompt as an administrator and enter the command sfc /scannow, press Enter. The system will automatically check and, if possible, fix damaged system files;
- installation of K-Lite Kodeck Pack;
- system recovery if all else fails (returning the computer to an earlier state - when everything worked - using a checkpoint).
If you suspect problems with the hardware, you need to use the Aida program to check the temperature of the sensors to rule out overheating. Checking contacts, checking RAM memory for errors (for example, with the Memtest86 program), and stress testing the video card will help identify or eliminate problems in the operation of any component. If you are not sure that you can handle it, it is advisable to contact a specialist, since incorrectly performed tests can lead to computer failure.
Often the error is caused by the computer's power supply. Since all elements are operating under maximum load when calculating the performance index, they may not have enough power. If this is a laptop, check the power settings, they should be set to “maximum performance”, and the laptop itself should be connected to the network at this time. If a component problem has been ruled out, it may be time to replace the power supply with a more powerful one. Even a working power supply loses power after a year of continuous use, causing equipment failures and the “blue screen of death.”
The Windows Experience Index (WEI) is made up of several factors: processor power, RAM speed, 2D and 3D graphics performance, and hard drive data transfer speed. The overall score is determined by the lowest score. To increase WEI, there are several ways, including replacing the video card or hard drive, cleaning, checking for errors, etc. If the performance assessment does not work, then you should check your computer for viruses or find errors in the registry. Problems with the video card or power supply of the computer can also cause problems.
In Windows 7 there is such a useless index that shows system performance. Thanks to this index, you can determine whether Windows 7 is suitable for installation on your computer or not. But, to be honest, this index is needed only to show off a powerful system to your friends. Now we will tell you how you can increase the performance index.
If you want to ensure that you have a productive hard drive (as if), there is absolutely no need to buy a powerful hard drive with 15,000 rpm. There are two very simple ways that will increase your productivity index without cost.
Method 1:
This is the easiest way. You just need to download a cheating program called Windows 7 rating changer. It can be done . There should be no problems installing this program. The only thing you need to do after downloading Windows 7 rating changer is disable UAC and reboot the entire system.
The program is very easy to use.
You just need to specify the parameters you want. And that will be enough.
You can increase the index to 7.9. Then you need to click on the button “ Save».
Then you need to check the index again. And enjoy contemplating cool numbers.
Method 2:
This method is a little more complicated, but the result is also good.
First you need to go to this address - C:\Windows\Performance\WinSAT\DataStore.
After this you need to select the file Formal.Assessment (Initial).WinSAT.(necessarily the newest one, this can be determined by the date). When you open the file, you need to find the block highlighted in the figure below.
Change the numbers to whatever you want (maximum - 7.9).
You can even change all the parameters to maximum, but it will not look very realistic.
The photo below shows the result of the work done. Here we did not change all the parameters, but simply changed the overall performance index.
After all these manipulations, you will only need to save the file. And you can enjoy the cool performance index of your personal computer.

A modern computer is a complex device, the final performance of which depends on many factors. The speed of the hard drive, RAM, and video card power often become more significant than the clock speed of the central processor. An intuitive assessment of Windows system performance can roughly indicate the problem, but only the performance index can accurately calculate weak points and find a solution.
What is a performance index
To calculate system performance indicators, Microsoft uses test tasks that maximally load each individual computer hardware component. In this way, five indices are calculated: for the central processor, graphics, game graphics, RAM and the main hard drive. The smaller of these is considered the base index for the entire system. The scale starts at 1.0, the highest score is 7.9, but it rises as more powerful hardware solutions become available.
The base index is close to the average for a balanced general purpose computer, since all scores in this configuration are approximately equal. Dedicated hardware solutions are subject to deviations. For example, office computers usually have a weaker video card, while multimedia solutions require a faster hard drive. In such cases, the overall computer index will be significantly lower than the average, since it is determined by the lowest value. This leads to a simple rule: to increase the base index (and overall computer performance), you should increase the power of the weakest component.
If the hardware requirements for the installed software indicate a minimum base index value, this means that it will work stably on a computer with this or a higher index value.
How to recognize him
To see what your computer's performance index is, open Start, then Control Panel.
In the large “All Control Panel Items” window that opens, find the “Performance Meters and Tools” tab and go to it.
The same result can be achieved using a system search. Click "Start" and enter the word "Counters" in the search bar.
Another way to immediately go to the desired window is to press the key combination Win (with the Windows icon) and Pause/Break (a service key, usually located next to Print Screen).
The “Evaluating and increasing computer performance” window that opens contains a lot of information.
The central part is occupied by the current indexes of computer components with a brief description. The overall score is highlighted large and provided with a comment on the calculation “Determined by the lowest score.” Several buttons lead to help: “What do these numbers mean?”, “More about ratings and software (online),” “Tips for improving computer performance.” Windows 7 tries to clearly explain both the principles of forming the rating scale and the best ways to increase the base index. This window is especially useful when upgrading computer hardware, as it stores indexes from previous testing. You can use the special button “Display and print detailed information about computer and system performance” to print the current indicators, and then run a new test by clicking on the “Repeat assessment” on-screen button in the lower right corner.
The same button must be pressed to begin the current test, which usually takes a few minutes. At this time, the computer is operating at maximum power, the screen goes out and lights up several times, which is a consequence of ongoing tests and does not pose a danger.
What do the points mean?
Possible maximum score
Although Windows currently advertises a maximum score of 7.9 points, this value can only be achieved in the maximum configuration, using the most modern processor, memory and graphics accelerators. The need for such powerful equipment usually arises in computers designed for resource-intensive applications - games, virtual reality systems, and so on. For specialized solutions, lower performance of the base index is considered normal.
Table: scores and performance description
| Points | Description |
| Up to 3.0 | Office packages, networking. Some graphics features of Windows 7 (Aero branding) will not be available. |
| From 3.0 to 4.0 | The Windows 7 GUI is available, but may be slow or crash when running in Full HD mode or on multiple monitors at the same time. If the overall score is low due to graphics parameters, then the computer may not be able to cope with streaming video, for example, when receiving high-definition television. |
| From 4.0 to 6.0 | Windows 7 can run at full capacity, including multitasking and using multiple monitors. |
| More than 6.0 | Powerful computers with high-speed hard drives. Can be used for 3D games, high-definition video streaming, and resource-intensive tasks. |
Considering the methodology for forming the index (based on the lowest indicator), there are no clear boundaries between configurations. A powerful computer with a slow hard drive and a balanced weak hardware solution can have the same index value.
How can you improve your score?
An obvious way to increase the overall performance of a computer is to update its weakest nodes. RAM can be replaced with a faster one or simply increased in quantity. The same goes for the hard drive. On a desktop computer, you can also replace the graphics card or processor. Laptops have significantly less upgrade capabilities. A more economical way is to configure the system and its individual components, allowing you to eliminate some restrictions in their operation.
Graphics settings
Visual effects, high screen resolution, and working with multiple connected monitors take up a significant portion of the resources of the computer’s graphics nodes. Therefore, you can reduce the load on this component and, accordingly, improve overall performance by disabling some Windows 7 options or reducing the screen resolution.
To change the graphics settings, you need to right-click on a free area of the desktop. In the context menu that opens, select the “Screen resolution” line.
The “Screen Resolution” window that appears contains other parameters of the connected monitors, for example, graphic design (themes). Now we select the "Resolution" drop-down list.
From the list of possible resolution options, select a lower one than the current one.
Hard drive care
Cleaning up unnecessary information and maintaining a sufficient amount of free disk space can significantly increase the speed of the drive. In addition, if the computer does not have a solid-state drive, but a regular disk, then it is necessary to regularly carry out the defragmentation procedure. This operation combines disparate parts of stored files, bringing them together, thereby reducing read and write times. The reader needs to spend less effort to move from one part to another if they are located in a row. In addition, free space is also consolidated, allowing new files to be written as a whole block.
Click the “Start” button and type “Disk Defragmenter” in the input line, then select the tab that appears with the same name.
The system shows all available drives in one window, allows you to analyze their status and carry out immediate defragmentation.
For regular operation, you can set up an appropriate schedule so that, for example, you run the utility at night.
Defragmentation takes considerable time if the hard drive is large and there is little free space on it, so it is recommended to delete unnecessary information first - this will speed up the work.
System care
Timely updates, replacing drivers with current ones, and using special programs to detect problems in software are also of great importance for the index. You can use the system interface to update the driver for the selected device.
Click the “Start” button and type “Driver Update” in the input line. The system shows search results, including the “Device Driver Update” tab we need, to which we go.
The main window of Device Manager contains a list of all hardware components installed on the computer. We select the one whose driver we want to update and right-click on its name.
By selecting the line “Update drivers...” from the context menu, we start the process. In the next window, the system will offer to choose one of two options: automatic search on the Internet or manual search on the computer.
The average user rarely downloads new drivers to the computer in advance, so we select “Automatic search...” and wait for the update. Windows 7 checks that the installed driver is up to date and updates it if necessary. The same steps should be taken for other devices from the list of “Device Manager”.
There are also many free applications, including those that do not require installation, that perform the process of checking and updating drivers in a semi-automatic mode. For example, DriverPack Solution first scans your computer and compiles its own list of hardware components and drivers. The program accesses the websites of device manufacturers and checks for updates, after which it downloads and installs new drivers. The application has a simple and friendly interface designed for entry-level users.
Changing Power Settings
To work more efficiently, Windows 7 sometimes deliberately reduces performance. For example, this applies to power settings. You can sacrifice some of the autonomy (for a laptop) or energy savings by preventing Windows 7 from switching to the appropriate modes. To do this, type “mobility center” in the search bar and select the appropriate tab.
There are several settings in the window that opens. We are interested in the power settings in which we select the high performance mode. In this case, you need to take into account: battery consumption will increase slightly, which will reduce the battery life of the laptop.
Using the ReadyBoost feature
There is free space not only on the hard drive, but also on external media, including USB flash drives. ReadyBoost allows you to reserve some part of it for the needs of Windows 7. To enable the option, you need to select removable media in Explorer and right-click the context menu in which to select the “Properties” option. Now all that remains is to go to the ReadyBoost tab and set the size of the reserved space.
If the performance review doesn't work or is missing
In some cases, the system refuses to evaluate performance due to cost considerations or more serious obstacles.
Time to troubleshoot
Possible reasons why the assessment could not be made:
- The assessment has already started. The ability to update scores is disabled while the test is running. You should either cancel the current process or wait for it to finish before starting it again.
- Lack of access rights. Sometimes the reason may be a restriction of user rights for a specific account. You should log in as an administrator and try to complete the assessment again.
- The laptop is disconnected from the network. Since calculating indices requires significant energy consumption, Windows 7 prohibits it from being performed when the laptop is running offline. The computer must be plugged into a power outlet.
- Lack of disk space. To evaluate Windows 7, you need a certain amount of free space on your hard drive onto which the test file is written. You should clean the drive as much as possible and then try the evaluation again.
- No multimedia support. Windows 7 can't measure the performance of computers that don't have multimedia capabilities.
- Outdated video driver. A faulty or outdated video driver will prevent Windows 7 from testing performance. You should check the latest system updates and, if necessary, install the latest driver versions or, conversely, return earlier ones. When installing drivers, it is better to use the official website of the manufacturer of your computer, and not, for example, a video card.
- Antivirus operation. Sometimes the cause is the active operation of antivirus programs. You should turn them off for a while and try the test again.
- Outdated BIOS. You should update your BIOS to the latest version.
Reinstalling video codecs
A common cause of the problem is damaged or conflicting video codecs. These are files containing video decompression algorithms, without which the computer will not be able to display the video on the screen. Windows 7 uses some of the system codecs to analyze the performance of graphics components, so their corruption or accidental removal makes evaluation impossible. Reinstalling will fix the situation.
Click the “Start” on-screen button and select the “Control Panel” tab in the right column of the menu that opens. In the large All Control Panel Items window, select the Programs and Features tab.
We remove video players, as well as codecs for them.
Click the “Turn Windows components on or off” button and go to the “Windows Components” window.
Find Windows Media Player, uncheck the box next to it, then exit the dialog box and restart the computer. After the download is complete, go to this window again in the same way, return the checkbox to Windows Media Player and reboot again. Let's try testing again.
If the problem is not resolved, the VC-1 codec required for testing may be damaged or missing. It can be installed along with the free K-Lite package for the popular player KMPlayer.
Scan system files
Another reason could be a failure of Windows 7 itself due to damage or deletion of some necessary system files. Press the Win+R combination and in the input line of the “Run” window that appears, type the command to start scanning the system and updating damaged files sfc.exe /scannow.
Installing additional components
One of the reasons for the inability to determine performance may be the absence of the MSVCR100.dll library on the computer. It can be downloaded for free from the official Microsoft website along with the 2010 package:
- https://www.microsoft.com/ru-ru/download/details.aspx?id=5555 - x32, x86.
- https://www.microsoft.com/ru-ru/download/details.aspx?id=14632 - x64.
If Visual Studio 2010 is already installed, but when you try to determine performance, the system reports problems with MSVCR100.dll, you should reinstall the package, first removing its old version from the computer.
Video: Everything you need to know about the Windows 7 Experience Index
When focusing on the Basic Performance Index when purchasing a computer, you should take into account that the current score is stored on the computer in an unprotected form in the folder C:\Windows\Performance\WinSAT\DataStore in a file whose name begins with the date of the test and ends with “. Formal.Assessment (Initial).WinSAT.xml." An unscrupulous seller can use a regular text editor to change the real numbers to the desired values. Therefore, you should carry out an actual test before purchasing.
The Windows 7 Performance Index is an indicator that, in simple terms, shows how cool your computer is (or how weak it is, depending on who you are). This is a great way to find out whether a given computer is suitable for cool games or all its capabilities come down to moderate carrying of office programs.
Understanding how to find out the performance of Windows 7 is necessary if you are going to buy a computer, but do not understand the hardware, and, accordingly, cannot understand how many megabytes of RAM and how many gigahertz in the process you need for your purposes. In general, if you don’t understand computers at all, then this was invented for you.
Before you find out the Windows 7 Experience Index, you need to click “Start” and select “Control Panel”. Here you need to set the view type to “Category”.
Then you need to go to the “System and Security” section and on the next page, in the “System” section, click on “Windows Experience Index Check”.
And a window with this parameter will open in front of you.
But finding out the Windows Experience Index is not enough. Now you need to understand which one will suit you and which one is too small.
Normal performance index
So, the Windows Experience Index ranges from 1.0 to 7.9. If you are going to do office work on a computer, then you need one with a performance index of 3.0 to 5.0. If your computer work involves serious graphics programs, then you need an index of more than 5.0. If you are going to play the heaviest games, then choose the highest performance index.
The normal Windows Experience Index is at least 3.0. If it is smaller, then working on such a computer will be inconvenient, programs will freeze.
How to improve your performance index
Before you can increase the Windows Experience Index, you need to know how it is calculated. Many people think that from the arithmetic average of each part, but in fact - from the lowest estimate of the hardware. That is, if the indicator turns out to be too low, it means that there is some kind of ballast in the computer that is pulling the entire system down. You can find such ballast in the same window of the performance index - the piece of hardware with the lowest score is the weak link.
Accordingly, in order to increase the Windows 7 performance index, it is necessary to replace this weak part with a more powerful one. Then the lower threshold of the assessment will rise, and with it the performance index of the entire system.
Usually the weak link is the video card. As a rule, they use an integrated weak card against the backdrop of powerful hardware, and installing a more powerful one will increase the performance index.
If you want to protect your device from mechanical damage, then you need a Xiaomi Red Rice case, which you can purchase here http://case4me.ru/1468-xiaomi-redmi-4a It will be much more profitable to take care of it in advance and spend a little money on a case than then pay for expensive repairs.
Personal computers are complex computing devices. The efficient performance of such a machine is achieved through the use of modern components, but, as is known, over time they become outdated. The performance index will allow Windows 7 users who are unfamiliar with computer hardware to determine what exactly needs to be upgraded.
What is a performance index?
The performance index, as the name suggests, is a tool that automatically evaluates the performance of a computing machine, that is, a personal computer, and its key elements. It should be understood that the system does not show the average value, but the smallest. For example, if the “Processor” parameter is equal to 4 points, and all the others are 5, then as a result you will see exactly 4 in the “Overall Score”.
Performance is determined by all key system parameters: “Processor”, “Memory (RAM)”, “Graphics”, “Game Graphics” and “Main Hard Drive”.
By looking at the table, any computer owner can independently find out which components need to be upgraded.
How do I get a performance rating?
Finding out your performance rating is not difficult. This can be done in two ways: through “Computer” and “Control Panel”.
View in computer and operating system settings
View the "Counters and Productivity Tools" option
In both the first and second cases, you will be taken to a section where you can look at the performance rating of your system. The window will display all the ratings separately, each of which relates to a specific element of the system, as well as the overall rating.
If you have recently improved some element of your personal computer, it is advisable to re-evaluate it manually. To do this, click on the “Repeat assessment” button.
This can only be done with administrator rights. If you are using a guest account, you will need to provide a password for the administrator account, otherwise you will not be able to change the computer performance rating.
What do the points mean? Normal index performance, what can be the maximum rating?
It’s easy to guess that the points you see in the table are an assessment of the performance of a particular system component. The Windows 7 operating system thus evaluates what tasks the computer can handle. If these scores are high, then there is nothing to worry about, since your PC can successfully handle even time-consuming tasks, but if you see values close to 1, then you should think about upgrading.
Let's consider all the elements: the “Processor” component is responsible for the number of operations that the installed processor can perform in one second of time. The “Memory (RAM)” component indicates the speed at which read-write operations are performed per second. “Graphics” is an assessment of desktop performance for the Aero interface enabled, that is, for the desktop itself. The next component, “Graphics for Games,” is already responsible for performance in various applications that require system resources, for three-dimensional graphics. The “main hard drive,” oddly enough, is rated by the speed of data exchange, and not by the capacity of the hard drive.
Optimal performance of the processor and other components
Normal performance index scores should be considered based on the priority tasks you will perform using your computer. If the computer will be used primarily for simple applications such as word processors, spreadsheets, email browsing and web surfing, then you should pay attention to the amount of RAM and processor. The rating of these indicators can be equal to 5, but you can not pay attention to the “Graphics” component at all - 2 will be quite enough.
Computer games and system resource-intensive applications naturally require the best components. If you are going to perform these types of tasks on your PC, then make sure that the “Processor”, “Memory” and “Game Graphics” components have the highest ratings. The hard drive in this case does not play the most important role, so a score of 3 points will be quite enough.
If your desktop computer will be used most of the time as a media console (you will watch movies or listen to music), then take care of the best “Memory” and “Processor” indicators. For all other components of the system, a score of 3 points will be sufficient.
Maximum Index Score
The maximum performance index score varies depending on the bit size of the system. Modern personal computers have 64-bit operating systems; 32-bit ones are less common. The bit capacity is determined depending on the amount of RAM. Thus, 64-bit OSes are suitable for devices with 4 gigabytes of RAM or more, and 32-bit ones, vice versa. This is due to the fact that 32-bit operating systems are not capable of reading more than 4 gigabytes of RAM. 32-bit devices are rated on a scale of 1.0 to 7.9. 64-bit architectures have a maximum score of 5.9 points.
Boost your score: How to increase PC performance in multiple ways?
Before you run to a specialty store that sells components for personal computers, you can optimize your operating system and PC. This procedure will slightly increase the estimate.
Changing the desktop display - increasing the rating
First, change the operating system interface display. For example, if you have Aero installed, then change it to traditional. The appearance of windows and menus affects the performance of the computer, so this procedure can significantly help you solve the immediate problem.
How to improve your index using diagnostics
Secondly, diagnose logical drives, optimize them, remove unnecessary files and programs. Remember that a cluttered hard drive significantly impairs the performance of the computer as a whole, so make sure that only what you really need is installed on your PC. After removing all programs and files, defragment it, which will allow you to reassemble all remaining files and folders and improve performance.
Thirdly, diagnose the drivers you are using. It is not uncommon that certain drivers can impair the operation of a computer and reduce its performance. If you receive a corresponding notification, then it is better to take care of updating and replacing them.
The last thing that will increase the productivity index is, of course, replacing old components with new ones. You can install an additional memory module if the motherboard has a corresponding connector, or install a more powerful one instead of the old one. On desktop PCs, every element is subject to modernization, everything depends only on your financial capabilities, but with laptops it’s more complicated. For such devices, you can only improve the size of the hard drive or RAM, and, unfortunately, all other elements cannot be upgraded.
Video: determining the performance index in Windows 7
Why performance ratings may disappear and what to do in this case
Typically, the computer performance assessment works offline, without any significant problems. However, sometimes there are errors in determining the rating, which may be due to: various software supposedly responsible for security when working on the network or codecs. Codecs are software designed to decode and encode media files. The thing is that the system performance assessment itself is based on the VC-1 codec, and when it is changed or upgraded, conflicts may occur.
Disabling antivirus
First try disabling your antivirus software (depending on the software you are using, the sequence may vary).
Removing and installing codecs
So, if disabling the antivirus did not help you, then you will have to remove and install all codecs manually:
- Open the Start menu and Control Panel;
- In the window that appears, find the “Programs and Features” option;
- Find installed codecs in the list and remove them (for example, K-Lite Codec Pack);
- Reinstall the K-Lite Codec Pack;
- Enter the program directory through the Start menu and run ffdshow video decoder;
- A window will open with a list of video codecs, find VC-1;
- Most likely, the Decoder parameter for this codec will be set to Disable, change it to Libavcodec and save the changes.
BIOS update
If these methods do not help you, then you may have to resort to updating the integrated BIOS environment, drivers, in particular DirectX, or roll back to previous versions. Log in as an administrator and navigate to C:\Windows\Performance\WinSAT\DataStore.
Here you should delete absolutely all files and restart your personal computer. After starting the OS, run the performance assessment again.
Scan system files
Sometimes this is not enough, which means you should check the presence of system files. You can do it like this:
The process of searching for problems in system files and then eliminating them will begin.
Reinstalling Visual Studio 2010
If you get an error when running a performance assessment that indicates MSVCR100.dll is missing, then you will have to reinstall Visual Studio 2010. This is a free library available for download by all users on the official Microsoft website. You need to choose a package based on the bit capacity of your system, and you can find it out like this:
- Open “Start” and on “Computer” right-click;
- Select "Properties";
- In the “System” section, pay attention to the “System type” parameter; the bit depth will be indicated there;
- Go to the Microsoft website and download the Visual Studio 2010 package you need (https://www.microsoft.com/ru-ru/download/details.aspx?id=5555 - for 32 and 86; https://www.microsoft. com/ru-ru/download/details.aspx?id=14632 - for 64);
- After downloading and installing, restart your computer.
The Computer Performance Index is a useful tool that allows the user to promptly determine the need to upgrade a particular part of the device.
