Internet and Modern Life
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.

The History of The Internet
In the world before the Internet, people communicated through letters, landline telephones and face-to-face conversations. It all changed when brilliant minds began to dream about a way to share information instantly, no matter the distance. In the 1960s researchers started experimenting with something called ARPANET, which was the first step to creating the Internet we know today. They connected computers using telephone lines, and instead of waiting forever for a reply, users could send messages almost immediately, making communication feel like magic!
As the years passed, many inventors and computer scientists came together to improve this original idea. They realized that by breaking information into tiny pieces and sending it through a network of computers, they could share data faster than before. Soon they developed protocols, which allowed different types of computers to communicate with one another. By the 1980s, the Internet had become a reality, as more and more research and academic organizations connected their computers.
By the 1990s the World Wide Web was introduced, making it easy for everyone to create their own online spaces filled with pictures, stories and games. Suddenly, the Internet was no longer just for researchers and scientists; it was a place for everyone. Помогите надо написать русскими буквами чтоб прочитать например and анд пжп пж
