• These computers that are connected to each other through the internet can interact with each other over the internet.

• These computers that are connected to each other through the internet can interact with each other over the internet.

• The Internet operates on a technique called packet switching.

• These packets contain information about the error control mechanisms, the address of the destination, and also the sequence in which the packets are to be transmitted.

• We order food using different mobile applications which also use the internet.

• In this article, we will discuss how the internet works in detail.

• Internet uses a packet switching technique to transmit the data. Thus, the data to be sent is divided into packets and the data is sent in the form of packets only.

• Each packet of data contains various information like the address of the destination, error control information, etc.

• Internet Protocol (IP) The internet protocol is a network layer protocol that is responsible for defining the rules that define how the information is sent over an internet connection from one computer to another.

• a transport layer protocol that works along with the internet protocol to transmit data over the internet.

• It is a connection-oriented and reliable protocol i.e. it establishes the connection first and then only, sends data over the established connection hence, there is no packet loss in the transmission control protocol.

• Once we enter the URL address of the website, the browser with the help of the DNS (Domain Name System) extracts the IP address corresponding to the URL address that is entered

• Once we get the IP address of the website we want to access using DNS, the browser sends an HTTP (Hypertext Transfer Protocol) request to the server to extract the HTM (Hypertext Markup Language)L webpage corresponding to the IP address.

• Web 3.0 majorly focuses on the data of the users. Various advanced technologies like machine learning are integrated with web applications that use the data of the users and hence, result in a much better user experience. `Blockchain technology is also commonly used in modern web applications.

• Internet majorly uses two protocols i.e. Internet Protocol (IP) and Transmission control protocol (TCP) to transmit data from one computer to another.

• The browser converts the URL entered by the user into an IP address using the domain name system. This IP address is more friendly to the computer than the URL.

• it sends an HTTP request to the internet server along with the IP address. The server responds back with an HTTP response which contains HTML (Hypertext Markup Language) information about the website. This HTML information is used by the browser to display the webpage to the users.

• HTTP establishes a connection on PORT 80 and hence, the HTTP request and response are transmitted on PORT 80 only.

• An internet is a huge network of networks that helps us to connect millions of computers together.

• contains the mapping of the URLs along with their corresponding IP addresses.
