What Is the Web: A Complete Beginner Guide
The web, or World Wide Web, is a system of interconnected web pages accessed through the internet using browsers. It allows users to view websites, access information, and interact online.
What Is the Web: A Complete Beginner Guide
The Web, also known as the World Wide Web, is a system that allows users to access and interact with information on the internet through websites. It is one of the most widely used services on the internet and plays a central role in how people browse content, learn, communicate, and use online applications.
While many people use the terms internet and web interchangeably, they are not the same. The internet is the underlying network infrastructure, while the Web is a service that runs on top of it and makes information accessible in a user-friendly way. You can learn more in our guide on how the internet works.
What Is the Web
The Web is a collection of interconnected documents and resources that are accessed using web browsers. These resources include web pages, images, videos, and applications that are linked together through hyperlinks.
Each resource on the Web is identified by a unique address called a URL. This allows browsers to locate and display the correct content when a user enters a web address.
- Web pages and websites
- Multimedia content such as images and videos
- Web applications and online tools
- Hyperlinks connecting different resources
- Browser-based access to information
Web vs Internet
Understanding the difference between the Web and the internet is important. The internet is the global network that connects devices, while the Web is one of the services that runs on this network.
The Web uses the internet to deliver content, but other services such as email and file transfer also operate on the internet without being part of the Web.
The diagram below shows how the Web is just one of the services that runs on the internet, alongside email and file transfer systems.
How the Web Works
The Web operates using a client-server model. When a user enters a website address in a browser, the browser sends a request to a server. The server processes the request and returns the required web page, which is then displayed on the screen.
This process happens quickly and involves multiple steps such as locating the server using DNS, sending a request, and receiving the response using HTTP or HTTPS protocols.
- User enters a URL in the browser
- DNS resolves the domain name to an IP address
- The browser sends a request to the server
- The server processes the request
- The server sends back the web page
- The browser renders the page visually
Browser → DNS → Server → Response → Browser → Display Page
Web Browsers
Web browsers are software applications used to access and view content on the Web. They interpret and display web pages using technologies such as HTML, CSS, and JavaScript.
Popular browsers include :contentReference[oaicite:0]{index=0}, :contentReference[oaicite:1]{index=1}, and :contentReference[oaicite:2]{index=2}. These browsers allow users to navigate between websites, interact with content, and run web-based applications.
Core Technologies Behind the Web
The Web is built on several core technologies that define how content is structured, styled, and made interactive.
- HTML for structuring web content
- CSS for styling and layout
- JavaScript for interactivity
- HTTP and HTTPS for communication between client and server
These technologies work together to create modern websites and applications that users interact with daily.
What Is Hypertext
Hypertext is a system that allows documents to be connected through clickable links. This is one of the core ideas behind the Web and enables easy navigation between pages.
When users click a link, they are directed to another page or resource, allowing seamless navigation across interconnected content.
Why the Web Is Important
The Web has transformed how people access information and communicate. It supports education, business, entertainment, and global collaboration.
From simple static pages to complex applications like e-commerce platforms and online tools, the Web continues to evolve and shape the digital world.
