Read, where in Windows 10 to look full information about the computer and its devices... What standard applications or third-party utilities to use for this. Sometimes you may need to quickly find information about your computer's configuration, operating system, installed drivers and supported technical modules, for example, the exact model of the network card, version "BIOS" or "UEFI", or which version "DirectX" installed on your PC.

In this article, I will talk about some of the standard tools operating system that provide this system information, both general and more detailed.

Content:

We learn basic information using a standard application "Parameters"

If you want to see a basic overview of your system, then you can find it in the standard appendix "Parameters", both Windows 8 and Windows 10. To open an application, press "Start" and then click on the button "Parameters"(gear icon) in the lower left corner of the window, or press the keyboard shortcut Windows + I... Next in the application, click on the icon "System".

After that, on the page that opens, go to the tab in the menu on the left.

Three sections with information will be displayed on the right side of the window. In the first, information about the protection of your PC in real time will be shown, the section provides basic information about the configuration of your PC, processor model, volume random access memory, device and product identifiers, and the type of system you are using (32-bit or 64-bit).

The section contains the name and version of your operating system, the date of installation and the build number of Windows. Also in this window, you can follow the links: key update and OS reactivation, read the license agreement and service agreement Microsoft.

The standard subroutine gives more detailed information

The (System Information) application was added back in Windows XP. With its help, you can see a much more detailed overview of both system information and information about the equipment used, much more informative than the previous method.

To open the window, press the combination Windows + R, and in the opened dialog "Run" enter "Msinfo32" and click "Enter".

The home page will immediately provide much more information than we saw in the app. "Parameters"... Here it is listed in more detail, your PC manufacturer, detailed configuration information, BIOS version, model motherboard installed RAM, etc.

But this is just the beginning. Expand the tree of tabs in the menu on the left, and you will see the real functionality of this application. Most of this information is probably useful only for developers. software and system administrators, but at the same time, there is almost all the necessary data about the system.

For example, in the section "Components" click on the field "Net" and further "Adapter" and the program will give full information about the device: name, model of your network card, manufacturer, driver versions, current state, as well as all related settings that are used in this moment.

Another great feature of this software is the ability to export information of interest to a text file. This option is extremely useful when you need to send data about your system or hardware errors to another user, for example, to support, or if you just want to keep a copy of your configuration and system settings just in case.

First, you need to select the desired section or subsection, the information from which you want to export. If you select a section, the exported file will contain data from all sections that are available in the application. But you can also select any individual section or subsection to save only specific information.

Then open the menu "File" and click on the command "Export".

A standard dialog for saving a file in Windows will open, just go to the desired directory and enter the names of the new report and press the button "Save".

Now at any time, you can easily open this file and view all the information and settings that interest you.

System Information on the Command Line

If Windows does not boot in normal operating mode, you can use the special command to get system information. "Command line"... Using this option, you will not be able to obtain such detailed information, as in an application, and, perhaps, this option is more complex than a regular application, but still this command will be extremely useful in the case when the operating system starts "Show off" and stops loading normally.

After the standard command line prompt, you need to go to the directory where this program is located, enter the following command "Cd C: \ Windows \ System32"... Next enter the command "Systeminfo" and press "Enter"... After a little analysis, the program will display several lines of information you need about the assembly and OS version, processor, BIOS version, boot disk, memory, and network information.

Device Manager in Windows 10

Device Manager is a standard component of the operating system that provides information about all devices connected and in use at the moment. It is also the only driver management tool for each installed device, manages the resources allocated to it (interrupt requests, DMA channels, memory areas, I / O ports). It also provides a lot of additional information.

You can open it in Windows 10 in several ways, the easiest is through the search, for this click on the icon "Search" and start typing the expression, our option will be at the very top of the search results list.

In the window that opens, all installed devices on your PC.

Go to any section, for example « Network adapters» and click on the line with the device name.

The properties window of this equipment will immediately open, at the top you will see several tabs: events related to the operation of the device, the resources it uses, power management, general information about the device and driver management. Actually, all the functionality of managing this device is collected here, you can update the driver, remove the device, disable it, and so on.

How to find out the version "DirectX"

"DirectX" Is a special set of ready-made graphic elements, procedures and functions that operating Windows system provides for use by external programs. "DirectX" specially designed by the company Microsoft to facilitate the development of graphical applications for Windows, most programs, one way or another, but use it to visualize all kinds of data. Most often it is used to write computer games. And if you installed a game that needs more than a new version "DirectX" than the one installed on your PC. Then, having found out which version is installed, you can understand whether you need to update it or not.

The easiest way to do this is by running the standard OS utility. To do this, press the keyboard shortcut Windows + R, and in the window that appears "Run" enter and press "Enter".

As a result, the utility will start DirectX Diagnostic Tool... The first tab of the program window will display some information about the PC and version information "DirectX"... In fact, this inscription only says which version of the program is active and in use at the moment, and not which version is the last one installed on your PC. After updating the "Windows 10 Fall Creators Update" in this window, the utility always shows version 12. But then the question arises that not every video card can support this "DirectX"... The version of the program that your device supports can be found in the section "Screen" standard application "Parameters" Windows.

Additional utilities

Of course, there is a whole host of third-party paid and free software available on the Internet that can provide even more specialized information.

For example, if you reinstalled the operating system and the new OS did not install the correct drivers for all necessary devices and they are not displayed correctly in "Task Manager" or are not working at full capacity. Then free software can help in such a situation - "CPU-Z"... You can easily download it from the official website of the developers.

The program will scan your system and display the most complete information about the configuration of your PC, even without the installed drivers. Information about the motherboard, processor, RAM and slots for it, information about the video card, the program will allow you to test the performance of your processor and compare its results with the rest. It will also provide the ability to save the full report in text or "Html file".

You can also take a closer look at the program "HWMonitor" Is a great tool for monitoring various aspects of your system, such as CPU and GPU temperature and voltage. BY Sysinternals Suite Is a collection of over 60 individual utilities that can provide you with a tremendous amount of information. As well as "AIDA64"- a program that will help you test and identify devices connected to your PC. Also, it will provide detailed information about the hardware and software installed on the PC. As I said, there are a lot of them, and each can be useful in a given situation.

Often there is a situation when a user buys, for example, a small powerful laptop, but the first glance at the purchased model is not enough for him. I would like to know information about all the stuffing that is installed in it (both software and hardware). It is clear that the seller will tell you what kind of laptop it is, the manual also contains basic information about all the components. But the user himself wants to make sure that everything stated is true. There are several basic techniques that allow you to get information about absolutely all the parameters of the device literally within a couple of seconds, and regardless of which OS modification is installed in each specific model.

Laptops: characteristics of the models. What should you pay attention to?

Naturally, visual inspection plays a role in the first place. Whether it's a small, powerful laptop or a gaming system that is large enough, a potential buyer pays attention to the screen first. It is important to know the diagonal and screen resolution here.

Then questions begin about the installed processor, the amount of RAM, the graphics adapter, the sound system, etc. The most inquisitive buyers are trying to get to the bottom of what connectors are in the device, which software components installed, etc., etc. So it turns out that specifications laptop includes information about both software and hardware. Further, several methods are proposed that allow you to obtain comprehensive information about all the parameters of any model of a laptop or stationary computer. They all apply to systems from XP to 10.

How to see the characteristics of a laptop using the simplest method?

The simplest method, which most users are used to using, is to view the minimum specifications with the definition of the model and type of processor, RAM and installed version(modifications) of the operating system.

You can find out such laptop parameters in the standard way, which is to call context menu right-click on the computer icon (or on the corresponding line in the "Explorer" for Windows 10) and use the properties section. But there is only a minimum of basic information here. Detailed characteristics from this section, as they say, cannot be squeezed out.

Using system information

Speaking about how to view the characteristics of a laptop in an extended version, you should use the special system utility Msinfo32.

This section can be called by the command of the same name, which is entered in a special console "Run", and it is absolutely unnecessary to run it as an administrator. There is already more information here. Here are presented not only the basic parameters of the laptop, but also some additional information, including the system build number, BIOS version, information about the motherboard, Hyper-V mode, etc. which you can even get information about device driver files. However, for the most part, few people pay attention to this. However, you can immediately advise to look at the section of devices with problems. In it, you can identify some problems even before purchasing a laptop.

But as a rule, such technical characteristics of a laptop are needed only by specialists who are versed in the operation of computers, who can immediately indicate whether the specified parameters correspond to the actual ones or predict how well this model will behave in operation.

View installed devices

In the question of how to view the characteristics of a laptop or stationary PC, viewing the installed hardware components (roughly speaking, computer hardware) plays an important role.

In this sense, an indispensable assistant is the "Device Manager", which is called from the "Control Panel", the computer administration section or through the devmgmt.msc command in the "Run" console (Win + R).

I must say right away that not all components are displayed in the main list, so you should use the command to display hidden devices. In the list presented, you can not only view devices by name, but also determine some of their characteristics, including conflicts or installed drivers... In addition, it is noteworthy that all components that for some reason do not work or function incorrectly can be immediately identified by highlighting them in the list with a yellow marker. As they say, you don't need to be to realize that there are problems with such devices, and they will have to be eliminated.

DirectX Platform Tools

Few ordinary users guess that in solving the problem of how to view the characteristics of a laptop, calling the DirectX bridge dialog (dxdiag in the application execution menu) can be of invaluable help.

The base page provides information on the processor and RAM, the installed OS and its assembly, DirectX version, etc.

The screen tab looks more interesting. Only with its help, unlike other standard tools, you can find out the amount of dedicated memory for a discrete video card (such models are mainly installed on mid-range laptops). You can also see the screen resolution with the current refresh rate settings and not to mention the version and name of the driver.

Command line

Finally, you can even get the necessary configuration information using the command line (cmd) when entering the systeminfo command.

In this case, the information provided to an ordinary user will not say much, but for people who are knowledgeable, such information can be very useful.

Third party utilities and online monitoring

You can also use some third-party programs to view the specifications of your laptop or PC.

Among the most popular are CPU-Z / GPU-Z, Speecy, HWMonitor, AIDA64, PC Wizard, etc. The information is broader in them and includes such parameters as processor temperature, fan (cooler) rotation speed, etc. ...

Online support is also available for many laptop models. For example, DELL devices with an active Internet connection can be fully tested on a special page. Based on the result, it will be possible to immediately determine whether changes have been made to the configuration and whether it complies with the standard of the model being produced.

Finally, some important information can be viewed even in BIOS settings(processor model and hard RAM, hard drive operating mode and much more).

Thus, you can get information about the characteristics of a certain model of a laptop or stationary PC in any of the above ways. But in order for the picture to be as complete as possible, you should not be limited to just one method, you need to apply them together.

It is very easy to get confused in all the variety of modern electronic devices and devices. An ordinary user is often interested in classifying devices by the type and complexity of the tasks they perform. To classify a device as one or another class, you need to know the characteristics of the device. Having studied the characteristics of a computer, you can determine: it belongs to a gaming, office or work model, the tasks that it is capable of performing, its performance and ways to increase it. Not all users have such information about their PC and how to find out the characteristics of their computer. Because of this, they cannot complete many simple tasks that are easily performed by experienced users. For example, check if the computer fits into the system requirements of a program or game.

How to find out the characteristics of your computer in Windows

The most basic (basic) characteristics of your computer can be found by standard means Windows without resorting to the help of third-party programs. However, if it seems to you that these characteristics are not enough to satisfy your interest or other need, then there is always a way to learn more detailed characteristics... Most often, third-party programs can help with this. There are complex solutions, and there are specialized ones. But more on that in another section of this article. In the meantime, let's figure out how to find out the characteristics of a computer in Windows.

How to find out what processor is on the computer and its frequency

The most accessible way to find out the characteristics of your computer is to use standard Windows tools. Many users, even inexperienced ones, are aware of one similar tool. To use it, you need to right-click on the “This computer” icon (or “My computer” depending on the OS version), then in the text menu that appears, left-click on the “properties” submenu:

After that, a panel "basic information about your computer" will appear, which contains information about the installed OS, the name and maximum clock frequency of the processor, the amount of RAM:

The main characteristics of the computer can be viewed in the properties of the computer.

However, the characteristics of the computer are far from limited to this information.

How to find out the number of cores and the cache size of your computer's processor

This information can be gleaned from the Task Manager by following these steps:

How to find out how much RAM is installed on your computer

You can find out the amount of RAM in the "basic information about your computer" panel. Instructions for launching it are given above. Also, this panel can be launched through the “Control Panel”. This requires:

1. Launch "Control Panel".
2. Select the view mode “large icons” or “small icons”.
3. Select the "System" panel by clicking on it with the left mouse button.
4. After completing the previous steps, the panel "basic information about your computer" will start, which will contain information about the amount of installed RAM.

RAM is never too much

You can also get here if you just right-click on the "Computer" icon on the desktop and then on "Properties", as we already wrote at the beginning of our article.

How to find out which video card is on the computer

Using standard Windows tools, you can also find out which video card is on your computer and how many there are. For this you need:

1. Run “ Control Panel”In“ large icons ”or“ small icons ”view.
2. Open the panel “ Device Manager”. It can also be opened from the properties of the computer. How to get to the properties, we wrote above. And the device manager is there in the left side menu.
3. There, go along the path: " your_pc_name / video adapters", Where all video cards of the PC (if several) and the currently used one will be indicated.

Many laptops have an integrated graphics card and a discrete

As you can see, there is not much information about your video card here. Only the title. If you need more detailed specifications of the video card, then read on.

How to find out which motherboard is installed on your computer

Information about the installed motherboard can be found in the System Information window. You must follow the following procedure to find out the name of the motherboard:

1. Hold down the "Win" + "R" key combination.
2. In the window that opens, enter “ msinfo32 ”And press the“ Enter ”key.
3. In the panel that opens “ System information”The list on the right will contain information about the brand-manufacturer of the motherboard and its name.

Motherboard make and model

There is another way to find out which motherboard is installed on the computer - to disassemble it. The motherboard model will most likely be written on it.

How to find out which drive is installed on your computer

Much less often than the rest of a computer, users need to know which HDD installed on the computer. The storage information () is also found in the System Information window. To get them, you need:

1. Enter the "System Information" panel (how to do this is described above);
2. Follow the path “System Information” → “Components” → “Storage Devices” → “Disks”. It contains information about the installed drives.

More or less detailed characteristics hard disk

In the screenshot, we see that a 1000 GB HDD is installed on the computer. It is split into two main volumes: 230 GB and 700 GB. Another 70 GB is inaccuracies in calculating the volume, or rather, the machinations of manufacturers. 1 GB is given for the needs of the system.

How to find out which power supply is on your computer

There are no reliable software methods to determine which power supply unit is installed in the computer. Most reliable way find out its characteristics - look at the official documentation of the power supply unit or a sticker on the power supply case, which indicates the name of the power supply and its power (both in general and along the lines +3, +5 and +12 V).

How to find out the characteristics of your computer through the command line

The characteristics of your computer can also be found through command line... It can be started by pressing the key combination "Win" + "R" ", after which you need to enter in the opened text line" cmd”And pressing the“ Enter ”key.

Command line commands that allow you to find out certain characteristics of the computer (the command line for their execution should be run as administrator):

• “winsat cpu –v”. Allows you to find out the name of the processor, its clock frequency, cache size, number of cores / threads and some other characteristics.

  

  Processor information on the command line

• “wmic memorychip get Manufacturer, Capacity, PartNumber, Speed, DeviceLocator”. Determination of the characteristics of random access memory.

  

  RAM information on the command line

• “dxdiag.exe”. The command launches the dxdiag application, where you can find out the characteristics of the video card (in the “screen” tab). Also in dxdiag you can find out the model of the motherboard (in the "system" tab).
  
  
  
• “wmic diskdrive get Name, Manufacturer, Model, DeviceID, Partitions, Status, InterfaceType, SerialNumber”- a command that allows you to find out the characteristics of the installed drives.
  
  

Programs through which you can find out the characteristics of your computer in more detail

The above methods to find out the characteristics of your computer are good because they are available to everyone and do not require the installation of additional software. However, some characteristics of computer hardware can only be found in specialized software. Another advantage of this method is its simplicity, it is much easier to look at characteristics in a structured form in the program menu than to use the command line for this.

CPU-Z - a free program for determining the characteristics of the processor, RAM and motherboard

CPU-Z Is a free utility with rich functionality. It is sure to be kept in their arsenal by overclockers who, in order to control the state of the CPU. We have already repeatedly written about CPU-Z in our various articles, so we will not dwell on it in great detail. If necessary, you can use the site search.

CPU-Z allows you to find out detailed characteristics:

• motherboard;
• random access memory.

GPU-Z - a free program for determining the characteristics of a video card

Unlike Windows tools, GPU-Z allows you to determine the number of shader processors, rasterization and texturing units, throughput video memory, video memory timings and many other characteristics of the video card. This is essentially an analogue of CPU-Z, only sharpened specifically for a video card.

CrystalDiskInfo - free disk drive characterization software

Allows you to find out the detailed characteristics of the drives (much more information than Windows gives). In addition, it signals the "health" of drives, the number of found and reassigned "bad sectors".

CrystalDiscInfo is one of the few programs of its class that can work not only with HDD drives, but also with a new generation of solid state drives - SSD.

The program has rich functionality, supports Russian and is absolutely free. You won't have to look for analogs, believe me.

CrystalDiskInfo interface

AIDA64 is a universal program that allows you to find out the characteristics of your computer in great detail

AIDA64 is a paid program, but it is possible to install its trial version for 30 days. AIDA64 allows you to find out the detailed characteristics of all computer components available to programs. The functionality of the program is not limited to this, it contains system stability tests, built-in tests for, and much, much more. All functions of AIDA are well structured, grouped into sections and subsections, which makes it easy to use the program.

How powerful is the functionality of this program? What if I tell you that she can even tell you about the physical dimensions of your components? Not bad, huh?

AIDA64 has very rich functionality. Just take a look at this screenshot.

Instead of output

Knowing the characteristics of the device you are using is an urgent need in the modern world, when electronic devices become outdated very quickly. Knowing the characteristics of a computer - a universal platform that can be used for a wide range of tasks - is all the more important, since it allows you to fairly accurately determine the speed and ability to solve the PC tasks assigned to it. Knowing how to find out the characteristics of your computer will be useful both for an ordinary user who uses a PC to solve their daily tasks, and for professionals who use it for professional work.

Windows 7 is installed on personal computers and laptops. Users are interested in the characteristics of a PC when they are going to buy it or when there are problems with the "hardware".

The need for device information arises in the following cases:

• When buying new equipment. In this case, the user is interested in the performance index;
• Modernization when it is necessary to replace obsolete components system unit;
• Installing and updating drivers;
• The PC freezes and it is impossible to immediately understand the reasons;
• At the time of buying new game... It is important to know what the video card and processor can handle;
• Interested in your PC;
• When you need to know the temperature of the hard drive and processor.

To find out the characteristics of the PC, go through the order Start / Computer / Properties. There you can determine the basic capabilities of your hardware.

There is a general assessment of the work of all systems of a personal computer - the performance index. It is an operating system service that measures its effectiveness. The score is determined by the number of points that are assigned based on the speed of decision making of the components. For Windows 7, the score ranges from 7.9 to 1.0.

The performance index tracks performance:

• Processor - its efficiency, in the ratio of operations performed at a certain time;
• RAM - the ability to carry out a certain number of operations per second;
• Interface graphs - graphical effects of the desktop and 2D games, which do not require high performance of the video card;
• 3D graphics - modern games requiring a 3D effect and special applications that put a load on the video card;
• Hard Drive - The ability to read and write information per second.

You can get information about the state of the PC through the "Device Manager". You can get to it through Control Panel / System and Security / Device Manager. "Device Manager" allows you to track the presence of all existing systems... It monitors drivers and their availability.

Windows 7 monitors audio and video separately using its own diagnostic tools. Through the Start menu, in the search for your computer, you will find DirectX.

This utility keeps track of the basic characteristics of the device. In addition to the main version of DirectX, there are also updated ones. DirectX can be downloaded from the official Microsoft website.

how still possible see the characteristics of the computer on windows 7? Among the standard Windows programs 7 there is a service "System Information". You can find them through the Start menu.

You need the following actions: Start / Programs / Accessories / System Information. Or just in the search for the "Start" menu, you need to type the word "Details". In the list of programs, "Start" will point you to "System Information".

Here you will learn about all the processes that take place in the device in detail. The utility consists of several components, each of which enables the user to track the block of information he is interested in:

• System Information - Basic information about the device. In particular, the name and version of the operating system, the type of processor, the BIOS version, information about the computer memory are indicated;
• Hardware Resources - Monitors hardware settings;
• Components - detailed information about devices: LAN card, mouse, keyboard, video card and others;
• Software environment - installed programs, drivers and services;
• Browser settings - basic information about the browser.

Programs that allow you to find out the characteristics of your computer

using programs? A good program for analyzing PC performance is conditionally free utility ASTRA32 .

• Determination of the type, its frequency, multiplication factor and other characteristics;
• Determination of the drivers that exist on the PC as well as their determination of their relevance and the search for valid versions on the Internet;
• Tracking the operation of the motherboard, BIOS and its characteristics, chipset model;
• Interface. Determining the speed of CD / DVD drives;
• M.A.R.T. information and tracking the temperature of hard drives;
• Memory modules and their performance;
• Identification of additional devices and resources that they consume;
• USB devices connected to the PC

And other.

Speccy Is a free utility that monitors the performance of the system unit. It provides the user with complete information about the PC, the state of its software and monitoring of the work of "hardware" in general.

• Processor: name, model, performance, and more;
• Hard disk: interface, volume of files, amount of stored information and storage capabilities;
• RAM: frequency, performance and more;
• Graphics card: resolution at run time, current capabilities, name, status, and more;
• Operating system: its name, licenses, installation time.

The program is freely installed on any media.

Everest Is a utility for monitoring the operation of a computer, its systems and software.

• Characteristics of their frequency, power supply, memory size;
• Information about manufacturers, installed utilities;
• Operating system information;
• PC monitoring;
• Information about licenses.

HWInfo Is a utility with extensive computer performance tracking capabilities. It makes it possible to fully track the work of the PC and its systems. The program determines the current temperature of the video card and processor and gives recommendations on the optimal temperatures for individual systems.

The list of programs that monitor the performance of your computer is quite extensive. Among them there are modern and past current programs that users love. Some information about Windows computer 7 saves to BIOS.

If you are interested in such issues as checking the speed of your Internet connection, testing the monitor or supporting stereo sound by the device's speakers, then our article will help you make the necessary tests quickly and without installing any software!

Knowing everything about your computer is pretty important. Firstly, it allows you to better understand the potential capabilities of your PC, and secondly, to compare the results of your system with the results of other users.

In order to fully test your PC, you can use special complex utilities, like, and the like. Something about the system can be found in the properties of the computer, but there are a number of indicators that are easier, faster and more convenient to find out using special online services. It is about them that will be discussed in this article.

What not to test and why

No matter how powerful modern Internet resources are, the fact that they work only in a browser environment imposes a number of restrictions on them. Specifically, with their help we cannot get direct access to the system and its parameters in any way. Accordingly, there is no, for example, online testing services for RAM or video cards.

True, there are several portals that have found how to get around this limitation. They offer to install a special client plug-in that collects data about your PC, transmits them to the server, where they are processed and displayed as a finished result in a browser window. It's not a pure online service, but still. From similar Russian-language sites I recommend DriversCloud.com:

After clicking on the "Start analysis" button, the plugin loader should be automatically downloaded, which in the installed form takes a little more than 11 megabytes (if the download has not started, you can download it manually on the page "How can I remove the plugin?"). If everything is already installed, then testing will start, the result of which will be something like the following summary table:

We will receive generalized information about almost all components of the PC. However, this is far from all the data! To the right of each description module there is a "Plus" button, by pressing which, you can select a number of additional characteristics in each category.

But that's not all :) As you might guess from the name, DriversCloud also allows for all the main nodes of your computer! In order to view the proposed list of updates, click the "Find Drivers" button under the table of your PC's specifications.

In a word, the DriversCloud service is quite intelligent, but, alas, it is not completely independent of third-party software. Completely online, using a regular browser, we can only test what concerns multimedia capabilities or network parameters:

• operation of the microphone (requires) and speakers;
• monitor settings (display size, color, brightness, contrast, etc.);
• work with files;
• parameters network connection(speed, browser used, IP address, etc.).

I offer you everything I could find :).

Internet speed test

Probably the very first and most logical thing that asks for verification is the speed of the Internet connection. Let's not break the logic :)

There are quite a few different services for testing Internet speed. Each of them can produce different results, so to get more accurate data, I would advise you to double-check the readings on different sites and calculate the average value, which will be as accurate as possible.

Here is a list of the most successful Internet speed testing services:

The essence of all of them is the same: your computer connects to a server, downloads certain test files from there, and then sends them back. Based on how quickly data is received and downloaded, the server calculates the average speed of your Internet connection. The received data is displayed in the form of beautiful pictures or plain text.

From the above list, one of the most accurate and beautiful Internet speed testing services is SpeedTest.net:

Characteristic feature this service is that before starting testing, you can select any available server in any city on the map! If you don't, SpeedTest will choose the one that is closest to your current location, which is calculated from the IP address.

To start testing, just click the "Start Test" button and wait until the download and upload of data is complete. By the way, the whole process is animated and you can see the progress of the transfer of test files. Upon completion of the test, a result will open, which will reflect the ping time, as well as the speed of receiving and transmitting data in megabits per second:

The most informative, in my opinion, is the Internet speed test from Yandex:

There are no embellishments here, however, there are a couple of nuances that distinguish the Internet meter from other services. Firstly, the measurement results are displayed not only in bits, but also in bytes, which allows us to quickly assess the actual useful download speed in the form we are used to. Secondly, if you scroll down the page, we will see a whole section with various technical and reference information!

The rest of the services mentioned work almost identically. It is worth paying attention to the fact that of them, the fastest is InetZamer.ru, MainSpy.ru allows you to see the dynamics of speed changes at different stages of testing, and 2ip.ru has a number of useful and even entertaining services that you may like.

Monitor testing

When buying a monitor, many users do not even think that it can and should be customized. Usually, the work of the monitor is assessed by us according to the criterion: "shows-does not show" :) So it has been with us for years without calibration by colors, brightness, etc. And, by the way, it is recommended to check the monitor settings a couple of times a year!

As in the previous case, I offer you a number of services for testing and adjusting the parameters of your display:

Each service allows us to define:

1. Uniformity of color rendering and absence of "broken" pixels.
2. Screen refresh rate (especially important for CRT displays).
3. Sharpness of the image.
4. Display brightness and contrast.
5. The correctness of the geometric proportions of the screen.

Before moving on to considering the services themselves, let's define a little bit about the algorithm of our actions. For displays on cathode-ray tubes, you need to carry out all the tests in turn and, along the way, correct each deficiency found using the on-screen menu called up by buttons on the monitor.

However, LCD monitors tend to require fewer tests as they are not as prone to knock out settings as their CRT counterparts. First of all, you should pay attention to the uniformity of color rendering when filling the screen with one color. If you find one or several dots of a different color on a plain background - these are "broken" pixels ...

Sometimes you can get rid of them by "warming up" the matrix with a dynamically changing image (for example, white noise) for a couple of hours. You can use the JScreenFix.com service for spot "treatment" of dead pixels.

The second common mistake in LCD monitor settings is incorrect brightness and contrast settings. To correct it, test pictures are usually used with grayscale gradations up to its lightest tones, turning almost into white. If you see all the gradations, then everything is correct, if not, try changing the brightness and contrast parameters.

I think now it will be easier for you to figure out why and how to use the offered online monitor tests. Therefore, now let's talk a little about each of them. And the first in the list is the Monteon.ru service:

This is a Russian-language service that contains the entire set of classic monitor tests. It is better to run all tests in full screen mode by pressing the F11 key on the keyboard or a special button on the lower toolbar. For CRT displays, it is advisable to run all tests. And for LCD, you can selectively check color rendition and brightness / contrast settings.

Fans to do everything quickly, as well as cat lovers will like another Russian-language service from the creators of online CatLair:

There are not so many tests here as on the previous resource, but in all tests there are images of cats on the button icons :). To hide the cats and all the panels with tips, you just need to click on the screen. A second click will return everything to its place. Naturally, it is better to conduct testing in full-screen mode as well.

The last service on our list is English-language, however, it provides us with a number of very interesting and useful (especially for CRT monitors) tests:

All tests are divided into three large subgroups here: "Color range" (color rendering), "Trailing" (dynamics) and "Homogenuity" (uniformity). Of particular interest is the second section, which allows you to test the display's capabilities to dynamically change the position of objects on the screen without distorting their shape. There are settings for the background and object colors, as well as the speed of movement.

The only drawback of the service is that a flash player of at least version 8 must be installed on the computer to work.

Sound check

It would seem that you can check in the sound: it is either there or it is not :) However, knowledgeable people working with sound or just audiophiles can tell you that there are many tests that allow you to determine the frequency characteristics of sound reproducing equipment, noise level and other parameters ...

For the average user, this whole theory is not particularly important. However, there are also practical cases from real life. For example, you bought headphones, but there are no marks on them where the left and where the right channel is ... The AudioCheck.net service will help you to accurately determine the correct stereo online:

We just need to go to the site, connect the headphones to the computer and press the channel check button (for example, "Left" for the left one). If you hear sound in the left earpiece, it means that you inserted them into your ears correctly, otherwise you will have to swap them :)

The service, alas, is English-speaking, but knowledgeable people on it can find many useful things. Here are collected and tests to determine frequency characteristics, and to check the dynamic range, and even, an online hearing test! A list of all tests can be found at https://www.audiocheck.net/soundtestsaudiotesttones_index.php.

Virus check

The last thing that can be checked online on our computer is the files. They are gigabytes of storage on the hard drives of our PCs and some of them can be very insecure! If you have downloaded something from the Internet and it does not inspire confidence in you, check it with the recognized online antivirus scanner VirusTotal.com:

This service allows you to test any type of data up to 128 megabytes using more than 50 anti-virus engines with the latest databases. All that is required of you is to select the file to be tested on the computer, send it for analysis and wait for the results. If your file has already been tested before, then the results can be almost instant!

A number of popular services work in a similar way, such as VirusScan.Jotti.org (up to 5 files no more than 50 MB at a time), VirScan.org (up to 20 files no more than 20 MB) or Metascan Online (1 file up to 140 MB). However, the Total Virus is the most famous and authoritative. However, one can say that no one can tell 100% whether a file is dangerous. Virus scanners only assume a threat, and it's up to you :)

If you want to scan the entire computer, and not just specific files, then there is such an option. True, for this you have to use Internet Explorer and a special extension to it. However, if this does not bother you, then I bring to your attention ESET Onlie Scanner:

This is a service from the developers of the popular NOD32 antivirus. It allows you to use the real ESET database to identify dangerous software on your computer using a special plug-in for IE. All you need to do is open the service, click the "Launch ESET Onlie Scanner" button and confirm the installation of the add-on, and then launch it.

However, it should be said right away that, alas, you will not be able to cure the found viruses using the service. The scanner only detects their presence and offers to download and install trial version antivirus package ESET Smart Security... However, you receive the List of unsafe files and nothing prevents you from manually deleting everything that you think is necessary!

conclusions

Modern Internet services, as we could see, have reached almost the limit of their capabilities, which are limited only by the peculiarities of browsers. And some even try to "jump" established restrictions by using our own online clients and plugins.

Of course, to the level of full-fledged programs in some cases online services fall short. However, for solving a certain range of tasks, they are even better than the usual software, since they practically do not depend on the power of your PC and can work in general on any device with a browser!
