WHAT IS INTERNET?

The internet is a global network that connects millions of computers and other devices, allowing them to communicate and share information with each other. It's like a vast digital web that enables people to access websites, send emails, chat with friends, stream videos, and much more. Essentially, it's the backbone of modern communication and information exchange.

EXAMPLE

Absolutely! Let's say you want to order a pizza for dinner. You go online, visit your favorite pizza place's website, and place an order. Your request travels through the internet to the pizza place's server, which processes your order and sends a confirmation back to you. All of this happens in just a few clicks, thanks to the internet connecting your device to the pizza place's system.

WHY IT MATTERS?

The Internet is the backbone of today's world.

It powers education and economy. It supports our health and well-being. And it connects us to our neighbors and to those we love. Americans without Internet miss out on many of these benefits. Roughly 1 in 5 American households aren't connected to the Internet. That's a fifth of our country that's unable to fully participate in modern life.

Access to the Internet isn't a luxury. It's a necessity. That's why the Biden-Harris administration is providing $65 billion to expand Internet access. We want to make sure that everyone in America has access to reliable and affordable high-speed Internet. High-speed Internet doesn't just help individuals. It helps our country. It saves us time and money. It creates jobs and opportunities here in the United States. And it helps us connect to one another, building a stronger, more free society.

JOURNEY OF THE DATA : FROM BROWSER

TO SERVER

First of all, try to understand : what is Data?

Data is a collection of facts, figures, or information that can be stored and analyzed. It can come in various forms, such as text, numbers, images, audio, and video. Data is the raw material that we use to gain insights, make decisions, and understand the world around us.

For example, when you fill out a form online, the information you enter (like your name, email address, and preferences) becomes data. This data can then be used by the website to personalize your experience or by the company to analyze trends and improve their services.

Is there a specific type of data you're curious about?

BEFORE GOING DEEP INTO THE JOURNEY OF DATA, WE HAVE TO KNOW WHAT IS BROWSER ? WHAT IS SERVER?

SO WITHOUT ANY DELAY, WE ARE DESCRIBING ABOUT THE BROWSER

WHAT IS BROWSER?

A browser, short for web browser, is a software application used to access and view websites on the internet. It allows you to navigate the web by entering URLs (web addresses) or clicking on links. Some popular browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.

EXAMPLE:

When you use a browser, it retrieves web pages froms and displays them on your device, enabling you to interact with content like text, images, videos, and more. Browsers also support various web technologies, such as HTML, CSS, and JavaScript, which are used to create and design websites.

FOR MORE BETTER UNDERSTANDING:

There is a girl name Pragati and a boy name Utkarsha. Both are having their food and sit together to eat it. So now, they have the same food. Suppose he is the browser and she is the server. Pragati has a beautiful pen with her. And Utkarsha as a browser takes the pen (web pages(pen is the webpage here.)). And then, Utkarsha showed that pen to others. So here , what happens?

The web browser(Utkarsha) collects all the information from the server(PRAGATI). And the information is in the webpage form. The webpage(pen) is now live and shown to all the internet users.

WE DISCUSSED LOT ABOUT SERVER , BUT WE HAVE TO KNOW ABOUT SERVER

WHAT IT IS?

WHAT IS SERVER?

A server is a powerful computer or system that provides resources, services, or data to other computers, known as clients, over a network. Servers can host websites, manage email, store files, run applications, and much more. They are the backbone of the internet, enabling the smooth functioning of online services and applications.

EXAMPLE :

when you visit a website, your browser (the client) sends a request to the server where the website is hosted. The server then processes the request and sends the website's data back to your browser, allowing you to view the site.

Now , We are ready to go dip into the journey of the data from browser to the server.

JOURNEY:

The journey of data from your browser to a server involves several steps. Here's a simplified explanation:

1. Request Initiation: When you type a website address (URL) into your browser or click on a link, your browser sends a request to the server where the website is hosted.

2. DNS Lookup: Your browser first needs to find the IP address of the server. It does this by querying a Domain Name System (DNS) server to translate the website's domain name (like www.example.com) into an IP address.

3. TCP Connection: Once the IP address is known, your browser establishes a connection with the server using the Transmission Control Protocol (TCP). This involves a "handshake" process to ensure both parties are ready to communicate.

4. HTTP/HTTPS Request: Your browser sends an HTTP (Hypertext Transfer Protocol) or HTTPS (secure HTTP) request to the server, asking for the webpage content.

5. Server Processing: The server receives the request and processes it. This may involve fetching the requested webpage from a database, running server-side scripts, or performing other tasks.

6. Response: The server sends an HTTP/HTTPS response back to your browser, which includes the requested webpage data (HTML, CSS, JavaScript, images, etc.).

7. Data Rendering: Your browser receives the response and renders the webpage on your screen, displaying the content for you to interact with.
