How do Websites and Several Applications use the Internet?

Let us understand in a simplified way, considering this article that you’re reading right now. How you’re accessing it? The answer is pretty simple, as we discussed above, this article is being sent via cable or radio waves to your system in the form of small data packets from our web server right through the router and switches.

Now, right after this, once your system receives those small packets, the system will pass the same to your web browser, and at last, your web browser (chrome, edge, etc.) will reassemble all those small packets in a singular unit so that you can now view the display for what you’ve requested from the server i.e. this article.

However, there are other specifications too which involved in this process, they are:

1. DNS Query: They act as a directory in the web browser. When you’re looking for any specific domain, let’s say www.w3wiki.org So here, your browser doesn’t know this address, and for that, it will start looking out for validation and a request will be sent to the server. Once the identity is confirmed from the database, you’ll get to see the results on your system.
2. Handshaking (TCP & TLS): When two systems connect via a router, the process of determining protocols, speed, compression, and error correction during that particular session is simply called handshaking between networking devices. In this, establishing a connection with that IP is what we call TCP handshaking whereas, it is also mandated to keep your system safe so that no attackers can read those data packets and for that, encryption is being created which is known as TLS handshake.
3. HTTP (Request & Response): When you request any page from the browser, take an example of www.w3wiki.org here, so when you send a request to read the article “ How does the Internet work?” then the server pushes the content to the form of CSS, HTML, and JavaScript and same will get distributed in small data packets. The moment your system receives those packets, your browser will start interpreting those packets, and the whole article will appear on your screen. (It might sound typical, but won’t take more than 3 seconds)

The bottom line is there are several technologies and architectures involved in making a stable and working internet connection right from the beginning. In case, you would like to read in-depth knowledge of these technologies, refer to these links:

The Internet is the world’s most fascinating invention to date. The journey started back in 1969 as a part of a research program and by the time of the ’90s, it became a sensation among everyone. Today, if you’re reading this, you should be thankful for the Internet. But have you ever thought about How Simple Internet Works?

In this article or essay, we will share a lot of insight about the Internet along with its working process, infrastructure, and many more. So, be ready for an extensive journey about the Internet Working Process starting with its brief background.

Key Highlights:

• There are mainly two components present by which the Internet works e.g. Packets and Protocols.
• Ethernet, IP, HTTP, TCP, and UDP comprise the basic infrastructure of the Internet.
• There are only five simple steps involved in the Working Principle of Internet.
• Along with 3G/4G/5G, the DSL and Dial-up are other important Connecting Modes.
• There are mainly three protocols involved in the Internet Working Method e.g. TCP, HTTP, and FTP.
• Switches and Routers, the Physical Infrastructure are the main pillars of the Internet.
