Advantages and disadvantages of network.

   Network is a group of computers which have an access directly to the main, central computer, which is called a server. There are many advantages of network.
Firstly, it keeps us from wasting our money to the extra hardware components. With the help of network only one printer or modem can be common to all computers in a common line. You will not have to worry about writing on a computer which doesn't have a printer or modem.
Secondly, it makes a great convenience to all the users. If you have something in a server to work on and you want somebody to do it, it's good to just send it through the wire to the computer where a desired person is working at. It is more comfortable than calling everyone to the server and have others work.
Thirdly, portability of network is greatly accepted in academic process. If a teacher wants to take a computer-based test from students, s/he will need to include tests to all computers. This can be done effectively fast with the help of network. What s/he has to do will be only install the test to the main computer and send it to all computers in line.
Since no part of technology is without disadvantages, there are numbers of disadvantages of network.
The first problem of having network is virus, which is the evil enemy of all computers. When hackers try to do something bad to computers on network, they, firstly, spread viruses to the server. As soon as virus gets into line all computers connected to server will get it too. As a result, there appears a big threat on the atmosphere of information protection in all computers.
The second problem is the availability to using data on a server via all the computers in line and its being available to everyone. This means any person may see what is on the server, and probably use it with bad aims. It shows that there is no opportunity to keep information secret.
The third problem is its width. If the network spreads wider including a lot of computers, it becomes difficult to manage with it. It will have some trouble in spreading data through all computers; computers start stopping time by time; some refusals to the work of the user will appear. 

Everyone liked this article, this is true. And  there are fairly few articles because it doesn't have any mistake  that could make students oppose at once. If this article were full of mistakes, only then there would be a huge number of mistakes. Because as you know, negative things are talked more than positive ones.

I also think that teamwork is better.
Oysha, you said that teamwork is not so great, because it doesn't allow teachers to grade according to each one's knowledge and participation in group work activities. And you said it may lead to some disagreements of students who were active in preparation. That's why this article is suggesting to make students work in groups with individual accountability, which means every student in the group is important and responsible for the grades In this case active students let other passive groupmates think As a result, active and passive students work with no exception and no one is disappointed.  

Toshkenboy, Yes, may be you are right, articles should be read by people with good English knowledge. But do you think it's good to just list the main points for which the article is devoted to? If it's OK,  in that case everyone can write articles, can't they?
I think it's better if he clarified what he means by each cause, not the definition of course, at least providing some statements why he thinks they are the causes, how those causes may lead to suicide. Article writers should say something by the article, not leaving the reader in his/her own thoughts. 

No, I don't.
Because suicide is more about delibarate action when one intentionally (not accidentally) kills that one. Drug addicted people don't kill themselves on purpose, but just a great amount of fix kills them. At the beginning of taking drugs they didn't start doing it with the aim of leaving the life soon. What surrounds their mind from the beginning taking drugs to their realizing that they die soon is the current drug reception and is more likely an enjoy from it.   

Lily, of course every (maybe not every) hard work leads us to success, bu it's already the upshot of hard work. It's the result of having such hard work that demands more time, energy and makes you feel tired. Without this kind of "unpleasant" process you cannot succeed. That's why we should keep in mind that hard work is only the way directed to success, but not the success itself. Before success you have a lot of challenging ways to go through, which is called hard work. May be that's why it seems unpleasant.

Valikhan, I strongly disagree with you. Yes, of course, we can understand the causes with the help of dictionaries if some words are unfamiliar for us. But I don't consider the article which just lists the main points as a perfect job. She should have devoted her article to the causes and doubtlessly, should have explained how the listed causes can result in the teenage suicide since the main indicator of the content meaning of the article,  is its title, which says about "CAUSES".
Also, the causes listed in the article can be understood in a number of ways. Because every reader has his own and different view on things. The author should have defined them based on her own outlook, clarifying them in his own way of thinking.

Ulbosin, I totally agree with that you found the content of the article doesn't match with what is written on the title. But I firmly disagree with that the writer should have provided the negative sides of hard work at the same degree with positive sides. He didn't miss to write negative sides, of course, he wrote them at the end. And that he preferred writing them at the end of the article was good idea. If he wrote the negative sides in the middle or somewhere we couldn't get what his purpose is actually.

And if he wrote negative sides equally with positive ones the article might have lost its persuasive function. As you know article should lead readers to think what the writer is trying to direct them and persuade them to one point, not two or three which is rather confusing for the readers

Even it hasn't yet been finished  it provides lots of useful information. You have very good tips that has taken into account every side of teachers' working with students. I really agree on the idea that teachers should act in a way that students could develop both their teamwork skills and the skills to work independently. Teachers should make every individual in a team be responsible and important for the grade all the team members get equally. Only then, teachers can have all their students involved in the appointment and work collaboratively enough. Otherwise, only the active students who consider themselves to know more than passive students may work more without letting passive groupmates do something about that assignment. 

What is my attitude towards study?

   Study is an important part of human's life. People spend a reasonable amount of time of their life in study. They study at schools, Universities where they can acquire knowledge of a whole world. As for me I regarded the study as a means of attaining my goal. In fact, I reached my goal, which was entering University, with the help of hard study . After entering University I started realizing the importance of study in people's lives, not in terms of learning the information by heart as I had done before. Because here, in high schools, you are not asked to solve the tests and provide rules of some subjects. All what you are asked is to express your opinion on all the aspects of life. And an opinion fed on comprehensive awareness of knowledge of all the world affairs is more likely to be appreciated. Furthermore, using the study for egoistic purposes is not considered a real study. Because, a real study which is independent of any aimfullness can make people capable of seeing how mysterious the real world is, as a result, able to discover a new world with a conscious mind. No other thing in the world can be like study, which brings light to darkness, activeness to boredom and passiveness, enlightment to gloom in people's life. That's why I consider the life that's lived without study as the small, obscure ray in a gloomy darkness, which is soon going to disappear.

What are the benefits and potential dangers of the Internet to children?

   The Internet is becoming a base source that is managing to present the anwers to thousands of purposes of people. It is considered the most widespread informational source as well. It provides a number of great benefits not only for adults, but also for children. First, children can get any information or current news on the Internet, since it's very important that children not be behind the times in such informatioinal technology period of humanrace. Second, they can load lots of entertaining sources such as music they like, books that are of interest for them or awesome games. Third, the Internet gives an access to keep the communication between young people going. Talking constantly to their friends, children may never feel lonely.
   Although the Internet has loads of reasonable benefits, there are still some dangers to be taken into account. First, there are games where girls become nude time by time depending on how well a player is playing the game. It may harm children's mind. Next, children may be addicted to doing with everything only with the help of the Internet. As a result, their life becomes virtual reality while it's considered abnormal for a normal person. Third, the availability itself to get everything one wants may be the disadvantage of the Internet. Because it can show anything ranging from violent performances to sexual process, which are likely to affect the children's psychology.
   In conclusion, I can say this much: Parents should be very attentive and even take control of their chidren any time their sweetes appear at the computer using the Internet.
