How Does the Internet Work? Simple and Detailed Explanation

When you visit this website, you have done what is called using the internet, it occurred to us, how does the internet work? Here I will explain simply and in detail.

How the internet works

Easy explanation

The scenario is when visiting a website, the first thing you do is open a browser and then type in the address of the website you want to go to or usually open a search engine and enter the search you are looking for, then click on the search results and enter the website you are targeting. When doing the above, what happens is the browser acts as an intermediary between you and the website to display visuals from that website, then the internet acts as a bridge to that website. When you press enter after typing a keyword in a search engine , the internet sends an HTTP request to the website’s server to send a copy to you using TCP/IP, then when the server accepts your request, it sends a copy of the website to your browser. After the browser receives a copy of the website, the browser will display the requested page from the website server. Simply put, when we download, what the internet does is Request , while when uploading, the internet does a Post .

Technical Explanation

The Internet (or internet ) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. Wikipedia

From the quote above, we know that the internet itself is a collection of many computers connected to each other using the TCP/IP protocol to communicate with each other. The internet itself is divided into several types of protocols, for details you can check Internet Protocol . Of the many existing protocols, the ones we encounter most often are the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) protocols. Examples of the TCP protocol are HTTP and FTP, TCP is in charge of negotiating requests and posts between hosts. Activities that involve TCP include browsing the internet, watching TikTok, YouTube, Facebook, downloading games, etc. While UDP is a protocol whose job is to make requests and posts without negotiating, this type of connection is usually used in games. Now, after knowing about TCP and UDP in simple terms, the main question is how does the internet work ?

The internet works using a packet routing network that follows the Internet Protocol (IP) and TCP. TCP and IP work together to ensure that requests sent by users are sent to the intended server/host with a secure connection, no matter what device is used and where you are. Data sent on the internet by us, usually in the form of messages and packets . The data sent to the internet is called messages , but before the data is sent to other servers/hosts, the data is cut into smaller sizes and those small data are called packets .

The internet identifies the data sender and the destination host using an IP address . The IP address itself is a number, for example: 127.0.0.1 (Local IP address).
