Today, when referring to the Internet, they usually mean only one subsystem of this giant computer network, namely the World Wide Web - the World Wide Web (abbreviated as WWW). The rest of the Internet is associated with secret science projects or work for military purposes.
Necessary
A computer with an internet connection
Instructions
Step 1
The Internet owes its appearance to the military department - the US Department of Defense. In the 1970s, the Pentagon decided to develop a reliable, fault-tolerant communication system that would provide connectivity even in the event of partial destruction. A team of scientists called ARRA was created. December 5, 1969 is considered the date of the Internet. On that day, three computers in California and one computer in Utah were successfully networked and exchanged data. This simple chain is called ARPAnet.
Step 2
At first, ARPAnet united several powerful computers in military organizations, training and research centers. ARPAnet owes its rapid development to scientific universities, equipped with computers and by that time having accumulated large volumes of electronic information resources. Of course, the possibility of sharing this data was of great interest to the scientific community. In the 90s, a new service appeared on the network - the World Wide Web. The ease of access and use of this service led to the fact that the most massive user - housewives and businessmen, teachers and students, etc. - began to connect to the World Wide Web, and the network became available to ordinary owners of personal computers.
Step 3
In order to appreciate the scale and variety of opportunities that the Internet opens up, it is enough to analyze what computers can do today. The answer is simple - a computer is capable of controlling almost any device or process that a person himself can control. From computers, in fact, powerful calculators, computers have turned into universal means of information processing and coordination of complex organizational processes.
Step 4
With the help of computers, movies are made, weather forecasts are made, medical analyzes are carried out, factories and spaceships are controlled, traffic is regulated, etc. In fact, today, thanks to the development of computer technology, humanity is one step away from creating artificial intelligence.
Step 5
The Internet not only gives the average user access to the results of millions of computers around the world, but also provides an opportunity to participate in the management processes themselves. A dispatcher, thanks to the Internet, manages a transport hub located hundreds of kilometers from his workplace, a doctor conducts a medical consultation for a patient in another city, a broker sends instant messages about buying or selling securities on the stock exchange.
Step 6
Today, the Internet provides e-mail, free information exchange services (FTP servers), search engines (search engines) and Telnet servers for remote access to other computers on the network.
