Background
The World Wide Web (WWW) was started by CERN (European Organization for Nuclear Research) in 1989.
Tim Berners-Lee, a British computer scientist working at CERN, invented the web to help researchers share and access information easily across different computers.
WWW often called the Web, is a system of interconnected webpages and information that you can access everyday using the Internet. Don’t confuse with Internet. Internet is used to connect a computer with other computer .
It was created to help people share and find information easily, using links that connect different pages together.
It’s an essential part of modern life, but how does it actually work? Here’s a beginner-friendly guide to breaking down its main components.
What is WWW?
WWW stands for World Wide Web and is commonly known as the Web.
The World Wide Web (WWW) is a system of websites and online resources connected by hyperlinks, allowing us to explore and navigate content. It's important to note that the web is often confused with the internet, but they are different.
The internet is the global network of computers that communicate with each other.
The World Wide Web is just one part of the internet, consisting of websites and online resources that we can access using a browser.
Components of WWW
Web Pages: These are the documents (like text, images, videos) you see on the web when you open a website using a browser.
HTML (Hyper Text Markup Language): This is the basic language used to create web pages. It helps structure the content, like where text, images, and videos appear on a page.
CSS (Cascading Style Sheets): CSS is used to make web pages look nice. It controls how things appear, such as the layout, colors, fonts, and other visual styles.
JavaScript: JavaScript makes web pages interactive. It allows actions like clicking buttons, filling out forms, or seeing animations when you interact with a page
Features of WWW
WWW is open source.
It is a distributed system spread across various websites.
It is a Hypertext Information System.
It is Cross-Platform.
Uses Web Browsers to provide a single interface for many services.
Dynamic, Interactive and Evolving.
How Web Pages are Accessed
URL (Uniform Resource Locator): This is the website address you type in the browser (e.g., https://www.example.com). It tells the Browser where to go and what page to show.
HTTP/HTTPS (Hyper Text Transfer Protocol/Secure):
HTTP is how your browser talks to the web server to get the page.
HTTPS is secure version of HTTP. It encrypts your data and making it safer when sent over the web.
DNS (Domain Name System ) : When You type in a website address, the DNS translates that easy-to-read URL into a special Number (IP Address) , so your browser can find the right server to load the page.
Web Development Basics
Creating websites involves two main areas: Frontend and Backend.
Web Browser: A program like Chrome, Firefox, or Safari that lets you view websites by displaying their content (HTML, CSS, JavaScript).
Web Server: A computer that stores websites and sends them to browsers when requested. It handles requests and delivers the necessary files.
The Role of Search Engines
Search engines like Google, Bing, and Yahoo help users find the information they need by indexing and ranking web pages based on relevance.
Conclusion
The World Wide Web is a huge network that connects people and information around the world. It's made up of different technologies that work together to help us access websites and share content. By understanding the basics, you'll be able to navigate the web more easily and even start creating your own websites.
