Training on a laptop for pensioners. PC course program for beginners
Hello Eugene! Respectfully yours, Oleg, one of the many who have purchased a video course, which in essence, step by step, turns the student from a mouse-driver to, as you put it, an advanced user without five minutes. At my age, many are no longer able to master it due to a number of reasons, but since, thanks to you, I am burning with desire, I am slowly, little by little doing it. Thanks for the school. I have done my homework and will move on. As they say, the quieter you go, the further you go. P.S: please write off possible grammatical errors, because just a driver Oleg Isaikin from St. Petersburg
Eugene, good afternoon! I briefly looked at the beginning of the video course, I have already found a lot of new things for myself. Now the work is connected with business trips, so there is no way to delve into it yet. I want to tell you that you are young! This is very required disks. In our provinces, qualified assistance is not available everywhere. With best wishes, good luck and good luck to you. Galina Anatolyevna, the village of Khor, Khabarovsk Territory
Forgive me, please, Eugene, but I thought I told you. I received the video course before the holiday. Thank you very much! The video course turned out to be a salvation for me, it helps to master the laptop very well. I'm very grateful to you. Wishing you a Happy New Year and also Merry Christmas! Lyudmila Nikolaevna Naumova Malaga, Spain
Hello Eugene! This letter came to me automatically. You probably remember that just before the holidays, they sent a parcel to Tashkent. The parcel arrived in perfect condition. Thank you very much for the discount and fast shipping. I'm already working on your CDs. I really like the way you present the material and the detailed explanation of even the smallest things. Once again, thank you very much for your hard work. You have succeeded in this work. All the best, with respect, Vladimir Alexandrovich Subbotin from Tashkent
Hello Evgeny Alexandrovich! Thank you, I like everything, I don’t understand everything as quickly as I would like, but I will definitely master everything. I am 61 years old, I have never approached a laptop and now I decided. Lots of unfamiliar words. I watch the course several times. I will definitely learn. Thank you for such literate and simple people to help us, you are a very good mentor. Lyubov Alekseevna Mironova from Moscow
I am a beginner PC user. I bought the CD "ABC of Computer and Laptop" and was not mistaken, I made the right choice. The disc came within a week despite the fact that there were holidays. On the this moment I am still studying and have not mastered the whole course. But there are already advances. Previously, if I wanted to do something on a PC, I did it using the “poke” method, and now, after several classes, I already work more confidently with a computer. Friends saw that I was no longer afraid to work with a computer as before, and were very surprised by my knowledge. Showed the disc, they really liked it. They also wanted this CD, so I ordered another set. P.S. Thank you very much! Your lessons are clear and not difficult for novice users like me. I advise everyone to start acquaintance with the computer with these classes! Julia Denisova from Tula
Hello, dear Evgeny Alexandrovich! I enjoyed watching your video course and would like to respond to your appeal in the section " Feedback". I have just become related to your voice, and you have become almost a member of our family! My husband jokes when he sees me at the computer, but it became obvious to me that in some matters I can already give him advice, he comprehends everything by the method " Of course, I'm not really flattering myself, but the main thing is that there is no fear: if I have questions, I can also search for information on the Internet. It is very noticeable that your popularity on the Internet has grown greatly since November 2011. for the first time I accidentally stumbled upon the link of your video course there. I am very glad to meet you. In a couple of months I learned a lot and learned a lot. I am moving slowly, but I feel more and more confident thanks to your lessons. I wish you every success and worthy appreciation of your work! Molokina Lidia Filippovna, Moscow
Evgeniy. I am very grateful to you. It was this knowledge gained with the help of the VIDEO AID and YOUR letters that I lacked. Now I do not ask ANYONE questions about using the computer and do not hear such expressions like: GRANDMA WOULD REMEMBER LONG AGO. Nikolai Dmitrievich Medvedev from Sterlitamak, Republic of Bashkortostan
The video course "The ABC of a computer and laptop" is a useful cycle of video tutorials, both for beginners to get acquainted with a PC, and for more advanced users. I want to note: I used the first two points for my relatives who stayed with us and always asked for something to explain. I sat them down at the computer, included video lessons - a basic course and 2 hours are free! By profession, I am a teacher at the Perm Medical College. For all novice students and my colleagues to learn how to work in Word - you can’t imagine better - it’s accessible, visual and very understandable. And, please, at least you write an abstract, at least tests - you are already advanced users. Thanks Eugene. Looking forward to your new tutorials! Svetlana Agafonova from Perm
Eugene, hello! My name is Tatyana Vasilievna. I am two months away from 60. Pensioner. Former teacher. Life goes on and you want to live, to live interestingly, keeping up with the times. I have been interested in computers for a long time. There was no financial opportunity to purchase this item. But I still went to computer courses. Free for pensioners. We got basic knowledge of working in "Word 2003", we didn't even touch the Internet. And knowledge was very necessary, because. a computer appeared, and I wanted to communicate with my daughter via Skype in order to save money and be able to see each other. I climbed the Internet, searched, hoped for good luck. And then luck smiled on me. I saw a message that you can quickly learn computer literacy! Cool!!! I read it. Decided to order CDs. Came in the mail quickly, without any delay. And now I'm happy to study everything that is there. Everything is very clear and clearly stated. New knowledge of what seemed to be known appeared. Everything has become easier, more accessible. Thank you. Tatyana Vasilievna, Penza
The article will tell you what a computer is and how to use it.

Nowadays, a huge number of people can use a computer and a laptop. But people are not born with these skills, everything once starts from scratch.
Beginners are interested in how to master a computer and laptop from scratch? How to start independent study of a computer / laptop? Let's talk about it in our review.
What is the difference between a computer and a laptop?
Virtually nothing. The main difference between a computer and a laptop is mobility. If a computer is a stationary device, then a laptop is a mobile device. That is, the computer must be installed on the table and used in the future, and the laptop can be freely carried with you, for which it is intended.
Both a computer and a laptop consist of a keyboard, monitor, mouse, processor, RAM, etc. Only a computer has all these components connected to each other, while a laptop is, as it were, a single monolithic device.
Both on the computer and on the laptop, an operating system is installed, for example, " Windows" (most common) or " linux". If you master, say, a computer, then you can already work on a laptop without difficulty and vice versa. Therefore, in this review, we will not give two instructions, but we will talk about how to use a computer.
The operating system is a kind of "soul" of the computer. it software which makes it possible to work on a computer. When you turn on the computer, it is the operating system that starts working first, we see this when the monitor lights up:
Let's start learning about computers operating system
If there were no operating system, we would see only a black screen and some incomprehensible letters with numbers that are of no use to us. Working on a computer is actually working with programs that, in general, make up the operating system.
You see how the mouse cursor runs around the screen - this is the work of the operating system. What about typing? Photo? Video? Even the sounds from the speakers are only possible thanks to the operating system. In the last century, music was listened to from the record on which the song was recorded. Now audio and video files are presented in digital format, that is, in the form of programs.
The operating system allows you to bring your monitor, mouse, keyboard, speakers, and all the devices that together make up your computer to life. Without it, the computer is just a "lifeless" iron organism. Remember, the operating system is the soul of the computer.
Windows
In general, operating systems can be different. Some of them are very famous, others are not very common among ordinary ordinary users.
« Windows» refers to the most common operating systems, which is distinguished by its convenience and is great for use not only by specialists, but also ordinary people at home.
« Windows» also happens various versions: « Windows 95», « Windows 7», « Windows XP», « Windows 8», « Windows 10" etc. The most common are the seven, eight and ten. The once popular Windows XP” is officially considered obsolete, although it is still quite possible to work on it.
Distinguish versions " Windows» among themselves can be in appearance:
There is also another easy way to find out what version of the operating system is installed on your computer:
- Click on the button in the lower left corner Start» left mouse button
- Next, click on the item " A computer" (or " My computer”) with the right mouse button.
- Then in the new window that opens, left-click on the item " Properties»
- After that, a folder will open in which information on your operating system will be indicated.
Find out what operating system is installed on our computer
So, we briefly studied what an operating system is. Now let's proceed to the study of the computer itself.
We study the PC device
Components of a computer
In order to learn how to work on a computer, you first need to study its design. That is, you need to know which devices are part of such a thing as a "personal computer".
In principle, most people have an idea of what the components of a computer are called, but we will explain everything in more detail so that it is easier for beginners to manage these parts.
So, the computer consists of:
- Internal parts- these are the elements that make up the system unit (a large box with a power button). In principle, the system unit is a computer, as such. And everything else, for example, a mouse, is just an integral part of this computer.
- External parts- these are, in fact, the components of the computer that we connect to the system side (keyboard, etc.).
In turn, all the described parts of a computer can be classified based on their interaction with a person:
- Input devices- These are devices that enable a person to give instructions to a computer (mouse, keyboard).
- Information output devices- devices that transmit information from a computer to a person (monitor, speakers).
- Input/output devices- these are, respectively, those devices that combine the concepts described above (disk drive).
Now let's talk about the main devices, without which work on the computer will be impossible.
System unit
What does the system block look like?
So, the system unit is the brain of the computer. To understand why the system unit is such an important part of the PC, you just need to examine what is inside it.
Inside the system unit is motherboard- this is a kind of huge microcircuit, in which, in fact, absolutely all elements of a computer are built in: processor, RAM, video card, sound card, disk drive, as well as all connectors (to which a monitor, keyboard, mouse, network cable and everything else).
You can also connect a Wi-Fi device, a TV tuner, and gaming consoles. This is a matter of taste and needs. When buying, you yourself order what kind of computer you need: for playing games, for watching videos or just for accessing the Internet. Based on this, the system unit is assembled with all its constituent elements.
On the system unit there are at least two buttons: turn on the computer and restart:
Power button on the system unit
All other important parts of the PC, such as the monitor, mouse, keyboard and speakers, are already selected under the system unit. That is, when buying a computer, you need to start with the system unit, and then select everything else for it. By the way, you can freely change the monitor or keyboard if they are out of order or no longer meet your requirements. But with a laptop, this number will no longer work.
Monitor
computer monitor
Everyone knows what TV is. Everyone watched him. A computer monitor is not exactly a TV, but it performs the same function, that is, the function of displaying information on the screen. If, in the case of a television, such information is transmitted via an antenna or tv cable (analog signal), then on computer monitor information is transmitted from the system unit. More precisely, the signal comes from the video card, which is located in the system unit, as we learned above.
Monitors come in different sizes, which is determined, for example, by the length of the screen diagonal and is measured in inches. The quality of the picture does not depend on the size of the screen. The screen resolution is responsible for the quality of the image. That is the number of pixels (electronic dots) per square inch. These dots on the screen make up the image. Accordingly, the more dots (the higher the screen resolution), the better, sharper and livelier the picture.
Speakers
Speakers
Just like a monitor, speakers receive a signal with information from the system unit, but they only output it not in the form of an image, but in the form of sound. This signal is transmitted from the system unit at the expense of the sound card.
Computer speakers differ from conventional classic speakers in that they also have an audio amplifier inside them. Sound card transmits only an analog signal (for example, as a player), and then the signal, as usual, is processed in the amplifier and goes to the speakers. Computer speakers have a cord with an outlet precisely because they connect an audio amplifier (not speakers) to the network.
Keyboard
computer keyboard
We discussed output devices above, now let's talk about input devices and start with the keyboard.
Everyone knows that the keyboard is designed to type text, which we then (or rather not “later”, but immediately) see on the screen. The keyboard, respectively, has all the necessary keys with letters, numbers and other symbols.
There are also keys, thanks to which we can give the computer certain commands. For example, if we press the " cap lock”, this will give us the opportunity to print the text in capital letters, or start a word (name, title) with capital letter. By pressing the keys on which the arrows are shown, we can scroll the page (on the Internet, or in any folder on the computer) up or down.
Mouse
Such a name computer mouse received for the reason that it is a bit like a living mouse, that is, it has a body and a tail (cord):
PC mouse
The computer mouse is designed primarily so that we can move the cursor on the monitor screen with the greatest comfort. If we were to use the keyboard exclusively, then this would give us unnecessary trouble and take a lot of time.
A standard mouse has two buttons (left and right) and a wheel. The left button provides, as it were, the main actions when, for example, we move the mouse cursor over a folder and open it by clicking on this button. In the same way, we close windows and programs - we hover over the cross icon and press the left button.
The right button is responsible for additional actions, for example, opens a menu or additional windows. The wheel, on the other hand, allows you to scroll the page up and down, as is done with the corresponding keys on the keyboard.

HOW TO LEARN TO WORK ON A COMPUTER IN TWO HOURS
Can an ordinary person master a computer in two hours? Most likely the majority will answer this question in the negative. I am of a different opinion. If children begin to play with the computer as soon as they learn to walk, then why do many middle-aged and older people find it difficult to master this complex household tool? I believe that the reason for this is the lack of a professional approach to the computer training system.
Ordinary people from the post-Soviet powers, whose knowledge base was laid back in Soviet times, are simply used to thinking in other categories. A different terminology is embedded in their consciousness, they are used to thinking by other criteria (more precisely, by other patterns). And what happens when they pick up any book on computers? The first thing they encounter is obscure terms that mean even less understandable categories. Interface, modem, processor, controller, etc. - all this scares and discourages any desire to take up the development of a computer. And sometimes these terms even have an ambiguous meaning (for example, the word "processor" as such, and the same word in the phrase " word processor' already have different meanings). Are children really mastering the computer with the help of these boring technical books and memorizing these incomprehensible terms? Yes, of course not. For them, a computer is a toy with which you need to play according to certain rules (the word algorithm is not yet clear for many of them).
To begin with, I needed to teach my father, who is 87 years old, how to play chess with a computer on his own. To do this, I wrote the instructions that formed the basis of this article. In addition, I have a friend who is afraid of the computer like fire, and any offer to use the computer triggers a defensive reaction in him, and he immediately declares “I don’t need this.” Therefore, I decided to post on the site the instructions that I wrote for my 87-year-old father, and according to which he could easily use my computer.
The purpose of this article is to help middle-aged and older people, and perhaps even children, master this incomprehensible thing - a computer in a few hours. I say again, if you have reached my site, then you do not need this article. But on the other hand, your younger brother, father or friend may need it, for whose training you naturally do not have time.
To learn how to use a computer (as they say now, to master a computer at the level of a novice user), you need to learn how to do four things:
1. Turn on the computer.
2. Run the program you need (it's best to start with some simple game). In most cases, application programs installed on your computer are indicated by a small image (icon or icon) that is reflected (highlighted, you can call it whatever you like) on the computer desktop (you will find the concept of this term a little lower, but for now do not get hung up) .
3. Turn off the program you are running. This operation is called - "close the program".
4. Turn off the computer.
First, let's look at a few concepts. Apparently, I can’t do without theory either, probably, that’s how we, people of the older generation, are arranged. But I assure you, the theory will not take more than five minutes and may help some to master the computer faster. What is a computer? This is such a thing, which usually consists of a small box (it is called a system unit) and a screen (it is called a monitor). It happens that both the system unit and the monitor are combined with each other. Then such a computer, depending on the size, can be called a laptop, netbook, tablet, smartphone, communicator, or something else. The image that appears on the monitor screen after turning on the computer and after the completion of all transient processes is called the desktop (see Fig. 1). everything that is shown in Fig. 1 is the desktop. Of course, desktop images may differ for each computer.
Elements of Fig. 1, which are necessary for the first lesson: 1 - pictograms (icons) of programs; 2 - Solitaire game icon; 3 - start button.
Any computer can only work with programs. Roughly speaking, programs are the rules by which a computer operates. If there are no rules, the computer will not work. Programs, in general, can be divided into two types. The first type is the operating system - it is main program, which is "invested" in a computer so that it can work. The task of the operating system is to control all other programs. The second type is application programs (roughly they can be called auxiliary), with the help of these programs specific tasks are performed on the computer (watching movies, photos, listening to music, playing various games, etc.). Well, perhaps that's all, the theory is over for today. Let's move on to practice.
In order to use your computer, you must first turn it on. To do this, on any computer, as well as on any household appliance or in any electronic toy, there is a special power button. Usually this button is located on the system unit. For your particular computer, you can find the location of this button in its operating instructions (description), or ask a more experienced friend, but be sure to remember where it is located, otherwise you will not be able to turn your computer back on.
After you turn on your computer, a cursor will appear on its screen (usually it is a small slanted arrow, but there may be something else - a cross or a vertical line of risk). Owners of tablets or smartphones do not have a cursor; your finger or stylus (a special plastic stick) performs its task. The cursor is controlled using the so-called mouse, the movement of which on a flat surface leads to the movement of the cursor on the desktop. The program you need is launched by hovering the cursor over the icon of this program and double-clicking (clicking or clicking) the left mouse button (LMB) while holding the cursor on the icon of the program you have selected. The image that appears on the monitor after the completion of transients when starting the program is called the program window. In our case, I launched the Solitaire game using its corresponding icon (see 2 Fig. 1), selecting it from a variety of other icons (see 1 Fig. 1) and got the Solitaire program window Fig. 2. How to work with a particular program is another question, and perhaps in my other tutorials for beginners, I will try to describe this process for the most popular programs. In order to launch the program, owners of tablets (smartphones, etc.) need to touch the stylus (or finger) to the icon of the required program.
So, in the screenshot of Fig.2 (by the way, the screenshot is taken using special program designed specifically for this purpose) presents the popular solitaire game, which you can learn to play by consulting with a computer user of any level, at least with a neighbor boy. Why do I recommend starting with a computer game? Yes, because it will not be so tiring, you will quickly learn how to control the mouse and be able to master the first basics of the process of communicating with a computer.
To turn off the computer, just move the cursor over the Start button on the desktop and click the left mouse button once while holding the cursor on this button. The "Start" button is a small drawing in the lower left corner, (see 3 Fig. 1), it can be in the shape of a circle, like mine, or a rectangle. It depends on the operating system that is on your computer. After you press the start button (left-click with the cursor on the "Start" button), depending on your computer, you will see a small window Fig. 3, in which you must select the item "Shut down" (or “Turn off the computer”) (see 1 Fig. 3). If you move the cursor over it (on this inscription), and press the left mouse button, the computer will turn off after a while. I draw your attention to the fact that on your computer the image in Fig. 3 may differ from mine, but you still need to look for the inscription "Shut down" or "Turn off the computer." I also want to draw attention to the fact that the "Start" button is not the button with which you turned on the computer, that button is real and is called the power button, and this drawn one is called the "Start" button. Probably, it would be more correct to call this button the Shutdown button (although it has other purposes).
If you did it all yourself, congratulations, you can already be classified as a novice user.
I intentionally missed one point in this manual. This is the shutdown of the program you are running. For most programs, this is not necessary, but there are programs in which it is necessary to save the current settings so as not to start the work (game) from the beginning. But the order in which parameters are stored is individual for each program, and the order in which this operation is performed must be considered when studying a particular program. And in order to turn off (terminate) the program, it is usually enough (this applies to most, but still not all programs) to hover over the white cross in the red rectangle, which is located on the right upper corner program window (see 1 Fig. 2) and press the left mouse button. And it would be nice if the user made it a habit to close all the programs they are running, although, I repeat, this is not necessary.

This article belongs to the series of articles " Computer training " or " Master the computer in two hours ". Other articles from this series:
Everyone who began to study a new business or skills for himself, faced with the fact that he had no idea in which direction to develop, where to move further and what the baggage of acquired skills should be. Learning a computer and working on it is also not such an exception for a beginner. Therefore, in this article, site site experts will give tips to help you master computer work more easily and even from scratch.
Computers are now used everywhere, so they solve a variety of tasks, ranging from accounting and design, to the management of such important facilities as, for example, nuclear power plants, automotive production and energy.
By including a computer in the medical tomograph and installing the appropriate diagnostic program on the computer, it will be possible to examine the body. Install an accounting program on the same computer, and it will keep track of finances. Therefore, we can conclude: depending on what programs you install on your computer, you can solve such tasks on it.
Where to start to master the computer?
- this is universal machine where anyone can solve their problems. Therefore, there are basic computer skills that every user should have. Each computer program, despite all their current abundance and specialization, also has a standard appearance or interface. All this helps the user to quickly master the work on the computer.One more conclusion can be drawn: the basic skills of working with universal programs used in specialized programs. This makes it easier to work with a computer, and, if necessary, the development of new programs.
This means that it is easiest to learn how to work on a computer by studying basic skills and knowledge. Below is a list of basic skills:
- the ability to create, open, copy, edit, move, delete - a folder, document or file. A novice user should know what is the difference between a folder and a file or document, how files are stored and how to store them correctly on a hard drive.
- use, because now almost every computer is connected to the Internet. Therefore, the security of the computer and the data stored in it must be at a high level.
- to use the Internet, in other words, to find necessary information, use e-mail, programs designed to communicate with other people.
- use various multimedia programs designed to view and listen to multimedia files. Multimedia files come in a wide variety of formats, so sometimes they need to be converted from one format to another. This is called conversion, and for this there are various programs - converters.
As a rule, working on a computer involves the simultaneous use of all these skills. For example, you need to find the desired document on the Internet, save it on your computer and send it to e-mail friend.
Since work on a computer is individual, each user decides for himself which programs should be installed on the computer. This means that it is desirable to be able to install or install them, in a different way, on your own. Accordingly, and delete, if necessary.
What else do you need to know about the computer to master it?
User or application programs by themselves cannot be installed or used without an operating system. This is the main and control program that allows the user to customize the computer according to his taste and preferences.The operating system is also the link between the user programs and the computer hardware. The operating system, controlling the computer, allocates the necessary resources for application programs: processor time and RAM.
Thus, the user must not only be able to use application programs, but it is also desirable that the computer be able to configure using the operating system. For example, the resolution and bit depth of the screen color palette. Or working with hard drives: defragmenting drives for faster work, checking drives and fixing errors, cleaning drives from junk files to increase free space and performance.
In the future, after gaining sufficient experience, you can independently learn
