  • What does Internet mean?
  • The Internet is an electronic communication network connecting computer systems.
  • The Internet is a multi-protocol network and can be defined as all of the interconnected computer networks. It is formed by connecting thousands of academic and commercial networks, state and free computer networks. Information between computers is transferred in packets according to various protocols. There are a wide variety of information and services on the Internet, such as electronic mail and linked pages. Games can also be played over the Internet.

 

  • The roots of the Internet are based on research from the 1960s by the United States government, which wanted to build a fault-tolerant, robust and private computer network. Special funds collected by the National Science Foundation in the 1980s for the financing of a new US backbone led to Worldwide participation and the merging of many private networks. With the proliferation of an international network in the 1990s, the Internet was at the heart of modern human life.

 

  • Internet Etymology
  • The English word Internet, which began to be used in 1985, is an abbreviation for Interconnected Networks, which means “networks connected to each other”. Inter- in the foreground comes in between English and mutual meanings. Net word means network.

  • History of the Internet
  • Semi-Automatic Ground Environment (SAGE), the military communication system, which is computer systems that communicate via the Internet via the network, and the Semi-Automatic Business Research Environment (SABER), a commercial airline reservation system, In the 1960s, the Advanced Research Projects Agency (ARPA) became the design fund of the Advanced Research Projects Agency Network (ARPANET) for the US defense system. Thanks to the projects created in the 1960s, the Internet reached its peak in 1969. After this date, ARPANET has entered our lives as a modern internet that we know. At the beginning of the ’70s, e-mail (SMTP) and NNTP applications became popular after American universities were given the opportunity to benefit from this project. They track FTP and HTTP. On April 30, 1993, CERN introduced the WWW prefix to the Internet.
  • Personal Internet use
  • To connect to the Internet with personal computers usually requires a telephone line. It can also be connected to the Internet via satellite, cable and radio broadcasts called Wi-Fi. The most common is to take advantage of the service of a company that provides an Internet service at a certain speed with an analog modem. Modem settings are adjusted according to the company’s service phone number and specifications, and the connect command is given. The analog modem converts the digital data (bits) of the computer into various audio frequencies and transmits it to the Internet service from the telephone line, in the same way the data is received.
  • Each displayed site has an address number. This is an address of four spaces, each of which has a value between 0 and 255. However, since the user can not actually hold this lean value for every site that will be dialed, there are DNS computers that keep these addresses equal to the Web page. Their task is to keep the IP address equivalent to each site name to be displayed and to direct the packets of the information transport protocol (TCP / IP) to this address. So you can reach the information on the internet that the internet traveler calls for a little effort.
  • Today, analog modems are replaced by digital (ADSL) modems that are faster and less error-prone. Their usage fees are reduced to a reasonable level due to the increase of plural participation. ADSL has an analog modem speed of 10x – 1500x times, allowing live video chatting as well as uploading a movie file in a short time frame.
  • WWW. Today, hundreds of millions of people around the world use virtual chat rooms, eCommerce, discussion rooms, Internet chat, and direct message (IM) downloads.

 

  • Today’s Internet use

Some of them are also called viruses because they act like viruses. The computer user sends information such as Internet habits, account numbers, etc. to harmful persons and organizations. While some are not so harmful, they work in the background while collecting data and occupy computer memory unnecessarily. Some spyware programs have been developed by official organizations to monitor criminals and terrorist activities.In addition, states use spying methods in computer environment instead of old methods of espionage, thereby reducing risk and cost accordingly.

 

  • Hackers
  • Other people are people who steal personal information by unauthorized access to information on electronic devices such as computers and phones. But that is not necessary. In sites where some hackers are involved, hackers help technical development of the sites.

 

  • Methods of protection from these hazards
  • The most effective way to protect computers against threats from the Internet is to use anti-virus, anti-spyware and firewall software. Many commercial security software today, such as Norton, Kaspersky, and McAfee, contain these three protections.

 

  • Other threats from the Internet
