Plans:
1.History of the internet
2. Before and now the internet
3. the internet is in our lives
The Internet is a huge network of computers spanning this planet and is now started to bring in the surrounding area like space.
The history of Internet began in the United States in 1969. It was a military experiment, designed to help to survive during a nuclear war, when everything around might be polluted by radiation and it would be dangerous to get out for any living being to get some information to anywhere. Information sent over the Internet takes the shortest and safest path available from one computer to another. Because of this, any two computers on the net will be able to stay in touch with each other as long as there is a single route between them. This technology was called packet switching.
The Internet has already entered our ordinary life. Everybody knows that the Internet is a global computer network, which embraces hundred of millions of users all over the world and helps us to communicate with each other.
The history of Internet began in the United States in 1969. It was a military experiment, designed to help to survive during a nuclear war, when everything around might be polluted by radiation and it would be dangerous to get out for any living being to get some information to anywhere. Information sent over the Internet takes the shortest and safest path available from one computer to another. Because of this, any two computers on the net will be able to stay in touch with each other as long as there is a single route between them. This technology was called packet switching.
Invention of modems, special devices allowing your computer to send the information through the telephone line, has opened doors to the Internet for millions of people.
Most of the Internet host computers are in the United States of America. It is clear that the accurate number of users can be counted fairly approximately, nobody knows exactly how many people use the Internet today, because there are hundred of millions of users and their number is growing.
Nowadays the most popular Internet service is e-mail. Most of the people use the network only for sending and receiving e-mail messages. They can do it either they are at home or in the internet clubs or at work. Other popular services are available on the Internet too. It is reading news, available on some dedicated news servers, telnet, FTP servers, etc.
In many countries, the Internet could provide businessmen with a reliable, alternative to the expensive and unreliable telecommunications systems its own system of communications. Commercial users can communicate cheaply over the Internet with the rest of the world. When they send e-mail messages, they only have to pay for phone calls to their local service providers, not for international calls around the world, when you pay a good deal of money.
But saving money is only the first step and not the last one. There is a commercial use of this network and it is drastically increasing. Now you can work through the internet, gambling and playing through the net.
However, there are some problems. The most important problem is security. When you send an e-mail, your message can travel through many different networks and computers. The data is constantly being directed towards its destination by special computers called routers. Because of this, it is possible to get into any of the computers along the route, intercept and even change the data being sent over the Internet. But there are many encoding programs available. Notwith-standing, these programs are not perfect and can easily be cracked.
Another big and serious problem of the net is control. Yes, there is no effective control in the^Internet, because a huge amount of information circulating through the net. It is like a tremendous library and market together. In the future, the situation might change, but now we have what we have. It could be expressed in two words— an anarchist's dream.
A few years ago it was rather difficult to imagine that it would be possible to communicate with people from all around the world. Students have the opportunity to speak to the professors from prestigious universities, ask their opinions and extend their range of interests. People have the opportunity to communicate with the people from other countries, find out their customs, traditions and even visit each other. I think that the Internet makes our world smaller and friendlier. We’ ve got the chance to learn more about the world’s history, our forefathers and gain more knowledge.
In the century of high-developed technologies youth can not imagine their lives without a computer and the Internet. Most young people spend all their free time surfing the Internet and communicating on (via) social networks. Personally, I’m sure there are a huge variety of other activities to take part. First of all, spending hours in front of computer teens go into a virtual reality of sites such as vkontakte and the facebook, and games such as “Line” and “Counter Strike”. They become addicted.
I think it is much better to live in the real world: meet friends and go for a walk, participate in various school activities and sports, go to the cinema and theatre. Moreover , computer and internet make people lazier. They stay at home instead of going out, they read less , they think less, and even talk less. Besides, if you spend much time such a way, your eyesight will worsen. But there is another point of view. Some people believe that the Internet makes life easier. You can sit behind him all day and do everything you want: know the latest world news, chat with friends from different countries, watch movies and play games online.
This device can replace all other options- they are sure. But I do not agree. If we do everything via the internet, we cannot cope with our problems and deals on our own. If it breaks, it is a tragedy for us – we are not be able to do elementary things :write a report , do the lessons, chat with people. In conclusion I would like to say, that it is a everyone’s own choice how to spend free time. But if you do not want to be lazy, unsociable, and totally dependent on the machine, spend less your free time in front of computer and expand the interests .
