The Internet (from the English Internet), the Internet, is a worldwide system of interconnected computer networks based on a set of Internet protocols. The Internet is also called a network of networks. The Internet consists of millions of local and global private, public, academic, business, and government networks interconnected using a variety of wired, optical, and wireless technologies. The Internet provides the physical framework for hosting a vast amount of information resources and services, such as the interconnected hypertext documents of the World Wide Web. The network is built on the use of the IP protocol and the routing of data packets. Nowadays, the Internet plays an important role in the creation of the information space of the global society, it serves as the physical basis of access to websites and many systems (protocols) of data transmission.
A protocol is a way of interaction, data exchange between computers when working in a network. In order for different computers to work together, they must “speak the same language”, that is, use the same protocols. The set of these protocols is called the TCP/IP protocol stack. the most common network protocols according to the OSI model at the application level – DNS. A DNS server (synonymous with a name server) is a server that contains a database of public IP addresses and their associated hostnames. Typically, a DNS server acts as a translator, resolving or translating hostnames to IP addresses. it can be noted that the principles of using DNS servers and unique IP addresses have become fundamental for the current digital age. Only thanks to them, the Internet has turned into a real living environment of a modern person.
