Testing Gigabyte video card GeForce GTX 750 on two computers. On a powerful computer with Intel processor i7 and on a weak computer with an Intel G620 processor.

Purpose of the test

Check the difference in game speed of one video card on two different computers. We will measure the game speed by the number of frames per second. We will test it at maximum and medium graphics quality settings. The display resolution in the game is 1920x1080.

There will be a frame counter at the top left. The more frames, the smoother the movement in the game. For a comfortable game there should be at least 24 frames per second.

The configuration of a computer based on i7 and a GTX 750 video card is described

G620 based computer configuration

• processor G620 Socket 1155, 2600 MHz
• Gigabyte motherboard
• memory 2 pieces of 8 gigabytes
• HDD WD Blue 1TB
• power supply FSP400-60HCN 400W

GeForce GTX 750 test in the game World of tanks

conclusions

On computers with intel i7 and intel G620 processors at maximum and medium graphics settings, GeForce video card The GTX 750 showed good results in the game World of tanks. The cost of the video card is about $150.

It performed equally well on a powerful i7 processor and a weak G620. At maximum graphics settings, the average result was 30 frames per second, with medium settings at 40 frames per second on both computers. The price of the i7 processor is $723 and the price of the G620 processor is $50.

This means that when choosing a computer for gaming, you don’t have to buy all the most expensive things. The main priority should be the video card. The quality of graphics and the speed of the game mainly depend on it.

Constructor
Each computer consists of several essential components. The main part of a computer, its foundation, is the motherboard. A processor, video card and RAM are installed on it; The power supply, hard drive and DVD drive are also connected to it. Various companies produce all these components, from which, like a designer set, they are assembled in specialized companies whole computer, also called a system unit.

Now computers are sold in all major electronics stores, but if you buy a system unit there, you are almost guaranteed to overpay for the brand. For example, in the M.video store (novosibirsk.mvideo.ru) a branded Compaq SG3-205RU XJ070EA computer is sold for 11,990 rubles. A slightly more powerful computer in terms of parameters, assembled in a specialized computer company, for example, Technocity (www.technocity.ru), will cost about 10,000 rubles.

Another disadvantage of large electronics stores is the lack of configurations cheaper than 11,000 rubles. In specialized computer stores, you can order a computer for the amount you are willing to pay for it; moreover, there are usually many computers in stock in different price categories. This, however, does not mean that computer stores will always offer you the best for pennies. To avoid buying a pig in a poke, you need to remember a few things.

Peaceful atom
There are not many manufacturers of computer components, so Novosibirsk stores sell approximately the same set of components. Most budget computers have motherboards with an Intel Atom processor. Such boards are produced by Intel itself, as well as by Zotac and ASRock. If you decide to buy an Atom-based computer, it is better to choose branded Intel boards, because they are more reliable and better quality than others. ASRock is a subsidiary of Asus and specializes in producing budget motherboards. All their products are of average quality and often fail within two years of use.

Motherboards with an Intel Atom processor have several disadvantages, but the main one is insufficient processor power. There are several Atom models: single-core and dual-core, with clock frequency 1.6 and 1.8 gigahertz. Such power is hardly enough to work with operating rooms. Windows systems Vista and Windows 7. It would seem that their requirements for a computer are small: a processor with a frequency of one gigahertz and one gigabyte random access memory. But to take full advantage of these operating systems, you'll need twice as powerful a computer. Many stores in our region, for example Level (www.level.ru) or Gotti (gotti.ru), sell inexpensive computers with an Intel Atom D410 1.6 GHz processor and one gigabyte of memory. As you can see, such a computer is slightly more powerful than is needed to work with Windows 7 or Vista. However, in addition to the operating system itself, you will need to run an antivirus, office or accounting programs, music player and so on. This requires additional resources, and a weak computer has nowhere to get them, since all the power is spent on running Windows.

Many people watch movies on their computers, including in high definition (Full HD). On office configurations with less than two gigabytes of memory, movies like this High Quality will “slow down”, that is, the video will lag behind the sound.

Keep your eyes open
Before you buy a computer, be sure to ask the salesperson to show you all the specifications system unit. The configuration parameters must include: the name, characteristics and retail price of all computer components (motherboard, processor, processor fan, RAM, hard drive and housing). Atom processors are cooled passively and do not require a fan. In other cases, pay special attention to the processor fan model. Many Novosibirsk stores stock the cheapest fans from Cooler Master and Titan, costing 150-170 rubles. These fans are unreliable and may fail after less than a year of use. It is recommended to install Intel, Cooler Master or Thermaltake fans costing 300-500 rubles. The more expensive the fan, the quieter it operates, the more revolutions per minute it can make, and the more more hours it will work. Manufacturers immediately include high-quality fans for some processors - in this case, next to the model name there should be a “Box” mark (for example, Athlon II X2 245 Box). If the processor is sold without a fan, then its name will be marked “Oem” (for example, Pentium E5500 Oem).

It is also worth paying great attention to the computer's power supply. To ensure normal operation of the processor, motherboard and other computer components, the power supply must be at least 400 watts. Reliable power supplies are used in Velton and Inwin cases.

In some Novosibirsk stores, sellers refuse to present the complete configuration of the computer. They explain this by saying that the system units are assembled in the technical department, and they are not given any information about what components are supplied there. If the store cannot clearly answer you what the computer consists of, we recommend that you go elsewhere. If you were shown the computer's specifications, check that all these components are in the store's retail price list.

After the purchase, you must be given a warranty card indicating all the components of the computer and their serial numbers. The warranty is given not for individual components, but for the entire system unit. For reliability, the warranty period should be at least 24 months.

OH HOW!
Those who are accustomed to perceiving a computer as a work tool will probably be surprised that there are people who, when purchasing it, are guided by how well it will fit into the interior of the room.

Trying to satisfy the diverse tastes of consumers, computer technology developers sometimes create the most unimaginable units in appearance.

However, do not forget that non-standard appearance system unit, monitor or keyboard significantly affects their price.

The modern world is so mobile that it is absolutely impossible to do without a computer. Electronic computers have appeared in various spheres of human activity, therefore for full-fledged work You need to choose this device wisely.

Personal computer device

To understand what a computer consists of, you need to look at the standard set of devices. However, it is worth distinguishing between several types of electronic computers:

So, the main components of the architecture personal computer are the processor, internal memory, video system, input/output devices. It must be recalled that this characteristic applies to stationary machines. More specifically, the following components can be distinguished:

• monitor (display, screen);
• system unit;
• keyboard;
• manipulators:
  • mouse,
  • joystick,
  • trackball;
• I/O devices:
  • scanner;
  • Webcam;
  • tablet;
  • microphone;
  • Printer;
  • acoustic system.

Of course, the monitor, keyboard and manipulators are included in the category of input-output devices, but they are distinguished as the main parts of the computer, because not a single stationary computer can do without them.

System unit

To understand what the computer system unit consists of, you need to clarify that it contains all the electronic components of the computer:

• motherboard;
• disk drives;
• hard drives;
• adapters and controllers;
• power unit.

There are also the following types of disk drives and hard drives:

• floppy disk drives;
• drives on hard drives (non-removable hard drives);
• removable hard disk drives;
• optical drives;
• flash drives.

What does it take to “create” your own computer?

If you want to “create” your own computer, you need to know how to assemble a system unit first. First, you need to determine what type of device the “created” machine will be: a budget option, a productive one, or an advanced one. The first category includes a computer that will perform all the tasks of a novice user: watching videos, playing games, surfing the Internet, etc. office programs. The second point includes models that are capable of performing the same tasks, but with greater productivity. Naturally, such a PC can be improved for the time being, since the main components will become obsolete and will be replaced with new ones. The third category includes machines that are particularly powerful. The disadvantage of such computers is their high cost.

Motherboard

The motherboard is the main component of the computer, since the other components of the computer are connected to it. When choosing a motherboard, you need to pay maximum attention, since the performance of the system and the possibility of improving it depend on it. The motherboard can be considered as a “collection” of devices, such as:

• CPU;
• memory;
• mathematical processor;
• expansion slots;
• Chipset.

Usually on this computer component you can find built-in elements, for example, a network, sound and video card. This situation should not cause any concern, because at any moment you can replace the integrated device with an external one. After all, when assembling a computer, you need to take into account what the computer consists of, since each type of computer requires different parts. In some cases, the use of integrated elements is not acceptable. The manufacturer cannot predict what one user needs in terms of performance and what another needs. Therefore, motherboards are equipped with special expansion slots, thanks to which it becomes possible to improve the computer.

CPU

The processor is the main device of the computer, which controls the operation of all components of the machine and processes all incoming information. The main characteristics and components of the CPU are:

The processor bit capacity refers to the amount of information that the CPU can process in one clock cycle. Today, most computers are equipped with processors that process 64 bits, although there are also 32-bit ones. Cache memory is a kind of buffer for temporary storage of data that the processor may need at any time. The CPU accesses this information much faster than information from internal memory. The system bus connects the processor and RAM. Modern CPUs operate at a frequency that exceeds the performance of this board. The difference between the processor and system bus frequencies is called the multiplier. The larger the multiplier, the greater the ability to overclock the CPU.

RAM

The main purpose of RAM is the ability to temporarily store information and support the work being done. software. Another name for this device is RAM (Random Access Memory). So, RAM is also included in the list of what a computer consists of, and these components must be present. Information in RAM is erased when the power is turned off or rebooted. RAM refers to dynamic RAM, also known as DRAM. Today, DDR2 memory is the most popular, but soon its niche will be occupied by DDR3, which is characterized by particularly high bandwidth and low power consumption. However, its disadvantage is the fabulous price. Experienced users recommend purchasing a motherboard that supports DDR3 so that in the future it will be possible to install this type of memory in the slot, although DDR2 is not much different in performance from its descendant. It is also worth paying attention to the number of slots for RAM: there should be at least 4 of them. This arrangement of things will make it more expedient to increase the internal memory. Today, normal computer operation already requires 2 GB, and in the near future you may need all 4 GB.

HDD

A hard drive, known as HDD, hard drive and screw, is an indispensable computer device that is necessary for permanent storage of numerous information. When the power is turned off, the information will not disappear anywhere. A hard drive is both an electronic and mechanical devices, which are characterized by wear of some parts.

To connect a HDD you may need one of three interfaces:

All three varieties are still in use today, although the first two types were developed back in 1986. If you purchased a new hard drive and are already connected to your computer, it needs to be divided into several logical partitions. There are several programs that will help you cope with this task. The list of their main functions includes:

• creating a new disk;
• deleting a section;
• change in dimension;
• formatting, etc.

Video card

A special device on a personal computer that displays images on a monitor is called a video card. We can say that it is the most important component. Other names for video cards: video card, video adapter, graphics adapter.

The main details of the device are:

• video memory;
• video processor;
• digital-to-analog converter;
• Video card BIOS.

Graphic adapters are divided into two types:

The first type is built into the motherboard. If broken, it cannot be replaced with another integrated part. However, you can use an external video card, which is also inserted into a specially designated slot on the motherboard.

The main characteristics of the graphics adapter include:

• video memory volume;
• RAMDAC frequency;
• video memory type;
• memory bus width;
• video processor clock speed;
• connectors.

Monitor

To display graphical and text information a monitor is needed, known as a display, a screen. There are two types of this device: liquid crystal; on cathode ray tubes. Great popularity in Lately receives the first type of monitor, because it is compact, less dangerous to eyesight, and produces greater image clarity.

The main characteristics of any display are:

• diagonal;
• permission;
• screen grain size;
• regeneration frequency;
• image formation;
• color display accuracy;
• viewing angle;
• energy consumption and radiation;
• interface;
• scope of application.

In addition to the main types of monitors, there are others that are used much less frequently in everyday life:

• plasma screens;
• organic LED;
• vacuum fluorescent;
• electrostatic emission displays;
• electroluminescent.

Keyboard

A keyboard is required to enter text information and control the computer. In a stationary computer, it acts as a separate unit, equipped with a main and additional module. The keyboard is included in the list of devices that determine what the computer consists of. You can work without a keyboard, but it is extremely inconvenient. In laptops this device built into the body. Modern device has 105 keys. If there are more buttons, it means they are designed to control multimedia content.

The keyboard is connected to the computer using one of three methods:

Some devices are equipped with a built-in touchpad, similar to the pointing pad used in a laptop. In addition, you can take a closer look at the keyboard, the shape of which differs from the classic one. The ergonomic device is divided into two parts, where the hands are located at a certain angle to each other.

Mouse

For convenient cursor control, a mouse is usually used. This device is classified according to the following criteria: by the number of buttons; by connection method; according to the method of action. Based on the first attribute, mice are divided into two- and three-button. According to the second - to devices connected via cable or wirelessly. According to the third, they are optical and mechanical. Optical specimens equipped with a micro-camera at the bottom have recently gained particular popularity. It is necessary to fix the position of the mouse so that the signal can be processed by the CPU in the future. Optical models are characterized by high accuracy, no need for periodic cleaning and the presence of a mat.

Printer

If you need to print information on paper, then you cannot do without printers. These are external devices connected to the computer via a cable. As a rule, they are connected via a USB port. There are monochrome (black and white) and color devices. In addition, printers are matrix, inkjet, and laser. The first type is used extremely rarely today due to its numerous and significant disadvantages - high cost, low print quality, high noise, low print speed. Inkjet printers Ink is applied through nozzles (special holes), and under the influence of electric current, the ink is fixed to the paper. The disadvantages of this type include low speed work, as well as the fact that when the ink dries in the matrix, the entire part must be replaced. Laser printers Printed using toner fixed by heat treatment. This device has only one drawback: its relative high cost.

Scanner

The device needed to digitize information through image analysis is called a scanner. An ergonomic model for work is a tablet copy. It is assumed that an object will be placed on the glass of the tablet. It should be positioned with the side being scanned down. The object is protected by a special cover. Under the glass of the tablet there is a mechanism developed from a set of mirrors and rulers. During operation, the platform moves and transmits a full image to the screen. The scanner is capable of digitizing photographs, text, film, barcodes, etc.

This device has the following characteristics:

• hardware resolution;
• optical resolution;
• color depth;
• type of optical system;
• way to connect to a computer.

How to choose a computer

When choosing a computer, you need to determine what tasks it should perform. There are three options for the purposes for which a computer is selected:

• viewing mail, film; listening to music; chatting in Internet;
• games; viewing mail, film; listening to music; chatting in Internet;
• work in powerful programs; viewing high definition video.

In each of the three situations, the computer will be selected in a special way. So, for the first case, it is necessary to choose computers that are not particularly powerful, with average characteristics. In the second situation, you need to consider the type of game. This is what determines how powerful the car should be. In the third case you will need powerful processor, large amount of RAM, powerful video card. When choosing any computer, you need to remember that the machine must be balanced. This means that all components should be approximately equal in performance. Otherwise, the computer will function incorrectly and irrationally.

Conclusion

Today, almost every home has a computer. Its role is difficult to overestimate, because the number of areas in which computers are used is constantly growing. Therefore, there is a need to study its main components in order to understand the working principle of mankind’s technological achievement.

Personal Computer is complex electronic device, designed to perform a wide range of tasks. This could be various calculations, calculations, listening to music, watching videos, various office tasks, games and much more.

Personal Computer can be stationary or mobile. TO mobile computers include laptops, netbooks and tablets.

A desktop computer has also recently undergone changes, but in most cases it consists of a system unit, a monitor, input devices (keyboard and mouse), audio devices (speakers, headphones and microphone), as well as others peripherals(printer, scanner, etc.).

For the normal functioning of a personal computer, you only need a system unit, a monitor, a keyboard and a mouse.

Also necessary operating system, in most cases they use Windows, but you can also download Linux.
Next we will take a closer look at each of these devices.

System unit

Main node personal computer is the system unit. It is a case, most often a metal vertical box, on the front panel of which there are power buttons and disk drives. All the necessary connectors and cables are located on the back wall. The system unit consists of a power supply, motherboard (also known as motherboard or “motherboard”), hard drive (HDD), video card, processor (CPU), random access memory (RAM), disk drives (CD/DVD), sound card and network card. Often, network and sound cards are integrated into the motherboard, that is, the radio elements of the board are soldered directly onto the motherboard.

power unit

The power supply is made in the form of a separate box, which is located at the top rear of the system unit and has several power cables for all elements of the system unit.

power unit

Motherboard

The motherboard is the largest printed circuit board in the system unit, on which all the main components of the computer are installed (CPU, RAM, video card), it also has connectors for connecting a hard drive and drives, as well as cables for USB ports and connectors for back panel housings. The motherboard coordinates the operation of all computer devices.

Motherboard

CPU

The processor is a chip designed to perform basic computing operations. Processors are produced by two companies: AMD and Intel. Depending on the manufacturer of the processor, the connector (location of its installation) also differs, so when choosing a motherboard you should not forget this. You just won't insert AMD processor into the motherboard for Intel processors.

CPU

Video card

A video card is a separate printed circuit board installed in the PCI Express slot of the motherboard and is designed to display images on a monitor screen. It processes the received information and converts it into analog and digital video signals, which are supplied to the monitor via a cable connector. A video card usually contains a processor (GPU) and RAM.

Video card

RAM

RAM is one or more small cards installed in special sockets on the motherboard (DDR). RAM provides temporary storage of intermediate data while the computer is running. RAM is characterized by access speed and memory capacity. Today, the fastest memory is the DDR3 standard.

RAM

HDD

A hard drive is a permanent storage of data; it can be user data, system data or temporary data. The hard drive stores the operating system, without which normal operation of the computer would be impossible. The operating system can also use the hard drive to save the contents of RAM (for example, in hibernation mode). It is a closed metal parallelepiped hard drive that is connected to the motherboard via a connector (SATA).

HDD

Drive

An optical drive looks like a hard drive, but has a pull-out tray on the front to accommodate optical drives. Serves as a drive for reading and writing optical discs.

Other additional devices can be installed on the motherboard, such as a Wi-Fi module or a TV tuner.

Monitor

The computer monitor serves to graphically present information that is clearly understandable to the PC user. Recently, exclusively liquid crystal displays (LCDs) have been produced. Monitors can be equipped with digital and/or analog video connectors (DVI, HDMI).

Keyboard

The keyboard is an integral input device of any computer. The keyboard consists of groups of keys for entering symbolic information. Also, many modern keyboards are equipped with additional keys, for example, for controlling media players and various programs.

In this lesson we will look inside the system unit and Let's get acquainted with all the main internal components computer.

In the third lesson we learned what a processor, RAM and hard drive are needed for. In the fourth lesson, we saw the outside of a computer and learned what the various buttons and connectors are for. Today we will open the cover of the system unit and get acquainted with all the internal components.

Computer internals

When people talk about the internal structure of a computer, they usually mean those components that are located inside its housing. For a desktop computer, the case is the system unit; for laptops and netbooks, it is the lower of the opening halves (let me remind you that varieties computer equipment we were dedicated).

System unit components

To begin with, let's take a system unit that is not too new, but also not too old, in which all the main components are installed. And then we compare it with a more inexpensive option with fewer additional components.

So, let's look at the photo of the system unit of the IT lessons website.

What we see if we remove the cover of the computer system unit

The first thing that catches your eye is that there are a lot of different printed circuit boards, “boxes” and wires. All boards and devices in a separate case are components that perform different tasks. Using wires, components exchange information and receive electrical power.

Let's look at all the components one by one.

1. Motherboard

All computer components are interconnected by one of the largest printed circuit boards (which can be immediately recognized in the photograph by their size), it is called system board or motherboard (in English version motherboard or mainboard).

System board (system unit component)

Some components are installed directly into the connectors located on the motherboard, while other components are connected to it using special wires into the corresponding connectors, and are installed in special compartments of the case.

You can learn more about the motherboard from subsequent IT lessons, but at a higher level of knowledge.

2. Power supply

In order for all components to perform their task, they must be powered with electrical energy. To supply this energy it is used computer power supply(in English power supply unit or PSU), from which wires stretch throughout the system unit.

Most devices have a special connector for connecting power, but some receive electrical energy through (which in this case will be an intermediary between the power supply and the device).

3. Central processor

We already got acquainted with the processor in, let me remind you that the task of the processor is to process information.

CPU(English) central processing unit And CPU) is installed in a special connector on the system board (the English name of the connector is “ Socket"). The processor socket is usually located at the top of the motherboard.

After installing the processor in the socket, a cooling system is installed on top - cooler(aluminum radiator with fan).

In the photo we see the cooler, under which there is CPU.

4. RAM

We also got acquainted with RAM in the third lesson.

RAM(RAM, Random Access Memory, RAM), like the processor, is installed in special sockets on the motherboard.

RAM (system unit component)

RAM is made in the form of a small printed circuit board with memory chips installed on it, this whole design is called “ memory module" Due to the specific shape of the board, it is called a “bar”.

The photo shows that there are four connectors, and two RAM modules, and they are installed in connectors of the same color to increase operating speed (more about this mode in subsequent IT lessons at more “advanced” levels).

5. Video card

Video card(video adapter, graphics adapter, graphics card, graphics card, video card, video adapter, display card, graphics card, etc.) is designed for processing graphic objects that are displayed in the form of an image on the monitor screen.

The photo shows that in this case the video card is made in the form of a printed circuit board ( expansion cards), inserted into a special connector on the system board (expansion slot). Since this video card gets very hot, you can see large cooling system(yes, this is also a cooler).

For the first time in IT lessons, we came across the concepts of “expansion card” and “expansion slot”, so we will immediately set a definition from which we will build in the future.

Expansion card– a device in the form of a printed circuit board with a universal connector for installation on the system board (for example, a video card, LAN card, sound card).

Expansion cards are installed in addition to the main components in order to expand your computer's capabilities, they can have different purposes (graphics, sound processing or connection with computer network etc.).

Example of an expansion card (a simpler video adapter)

Expansion slot- a special universal connector on the system board designed for installation additional devices computers made in the form of expansion cards.

We've sorted out the new definitions, let's move on.

6. Network card

LAN card (network adapter, Ethernet adapter, network adapter, LAN adapter) is designed to connect a computer to a computer network.

Network card (system unit component)

In this case, the network card is also made in the form of an expansion card (printed circuit board), which is installed in a connector on the system board.

7. Sound card

Sound card(audio card, sound adapter, sound card) processes sound and outputs it to Acustic systems(speakers) or headphones.

Sound card (system unit component)

Like the previous two devices, a sound card is a printed circuit board inserted into a connector on the system board. True, this sound adapter is not an ordinary one, it consists of two printed circuit boards, but this is an exception to the rule.

8. Hard drive

On hard drive All computer programs and data are stored (more about this in the IT lesson).

The hard drive, unlike previous components, is not installed on the motherboard, but is attached in a special compartment of the case system unit (look at the photo).

Hard drive (aka hard drive)

In such compartments you can install several hard drives and increase the amount of internal memory on your computer.

Hard drive is sometimes referred to by the acronym NMJD(Hard Magnetic Disk Drive), often said " Winchester"and on English language hard disk drive or HDD.

9. Optical drive

Optical drive(DVD drive, optical disc drive or ODD) is needed to read and write DVD and CD discs. Just like a hard drive optical drive is installed in a special compartment system unit.

Optical drive (system unit component)

This compartment is located at the top front of the case, it is wider than for the hard drive, since the DVD drive is noticeably larger.

System unit components (option 2)

So, we have looked at all the main components of the system unit. Now let’s see how the internal structure of a computer can differ using an example less expensive PC option.

The same components are visible in the photo, but no expansion cards are visible (video cards, network and sound card). How will this computer work without these components? In fact, these components exist, but they are not visible at first glance.

Built-in Components

The fact is that some components may not be made in the form of expansion cards, but may be built-in(integrated) into the motherboard or central processor.

In this case, additional chips are installed on the motherboard that perform the functions of a network and sound adapter. The video adapter is built (integrated) into the main chip of the motherboard.

In the photo, number 1 is the video adapter, number 2 is the network adapter, and number 3 is the sound adapter.

At the same time, expansion slots (number 4) remain on the motherboard for installing more functional components (if the built-in ones, for some reason, do not suit you).

Laptop components

In principle, it would be possible to make a separate lesson on internal structure of laptops and netbooks. But, in essence, there are the same components as in a desktop computer, only these components smaller size and are attached differently.

Each of the components listed in this IT lesson performs its task, but perhaps it is interesting to know which components most affect the speed of your computer?

Since most of the calculations are performed CPU, then it most affects the performance of the computer.

RAM The processor needs it to supply data and programs to perform calculations. Therefore, the amount of memory also significantly affects the performance of the entire computer.

If you need a computer for playing or working with 3D graphics , That great importance has operating speed video adapter.

But if the computer is used to surf the Internet, as well as text documents, photographs, watching movies and listening to music, then you can get by with the slowest (but modern) video adapter, including one built into the motherboard or processor.

Video supplement

To reinforce the new information, there is a very interesting video that describes in simple language the purpose of computer components. Unfortunately, the comments are in English, but there is a translation with subtitles (use the pause to have time to read).

Conclusion

So, in the seventh IT lesson we got acquainted with internal device of the computer and briefly reviewed everything system unit components. For the Beginner level, this knowledge is quite enough to consciously work in most programs that you may need.

In the next lesson we will learn what other devices can be connected to the computer (external devices), it is called.
