Internet
It is hard to deny the importance of Internet nowadays. This global system of interconnected networks has entered nearly everyone’s life and holds several billions of users worldwide. Internet helps not only to communicate, but offers infinite possibilities for business and education. It carries an extensive range of information and services. Other known media sources, such as television, radio, newspapers, have been reshaped, redefined and naturally replaced by Internet. It has enabled newer forms of human communications via instant messaging, social networking, video phone calls, forums, blogs, etc. Buying and selling different products became much easier. Many people prefer online shopping to time-consuming walks around the malls.
The benefits of Internet are obvious. People easily find up-to-date information in any required field. It is possible to get an online degree, to study in many prestigious universities from the comfort of one’s own home, to travel virtually and to learn about world attractions. However, opinions differ and many people emphasize disadvantages of Internet as well. Making world information easy to access is not always for good. First of all, the reliability of this information is dubious and secondly, children are under risk. They suffer from inappropriate information, placed on various websites. There were even cases when children became victims of criminal cases through Internet.
Not everyone is aware that Internet had started as a military experiment in the United States in late 1960s. It was supposed to help to survive during the nuclear war. If everything around got polluted and people couldn’t get out of their homes, Internet would be the only source of information and way of communication. It was the safest and quickest path from one computer to another. For this reason Internet was designed. As long as there was a single route between the computers, people could stay in touch. Subsequently, the modems were invented. They were the devices which allowed the computers to send certain information through telephone lines. Modem has opened doors to the Internet for millions of people. Since then the number of users is constantly growing.
Today, the Internet can be accessed almost anywhere and by numerous means, even by mobile devices. It offers great flexibility to students and employees.
