What is the World Wide Web?

The WWW is a system of linked web pages that you open in a web browser.

It uses these four parts to work:

  1. Web browsers (Chrome, Firefox, Safari) to display the pages.
  2. HTTP to move pages from servers to your browser.
  3. HTML to build the web pages.
  4. URLs like https://wikipedia.org as the addresses of pages.

The World Wide Web (WWW), also called the web, is a system of linked documents and multimedia that you access over the internet. It is one of the most widely used services on the internet. It lets users browse websites, find information, and use online tools.

Definition

The World Wide Web (WWW) is a system of linked web pages and media that you open through a web browser such as Chrome, Firefox, or Safari. Web pages are written in HTML (HyperText Markup Language) and are moved from web servers to your browser using HTTP (HyperText Transfer Protocol). Each page has its own address called a URL (for example, https://www.wikipedia.org).

Examples of the World Wide Web

The Web shows up everywhere in daily life. Some everyday examples:

  • Visiting websites: https://www.google.com for search, https://en.wikipedia.org for an encyclopedia article, https://www.bbc.com for news.
  • Online learning: opening a Khan Academy lesson at https://www.khanacademy.org or a course page at https://www.coursera.org.
  • Streaming services: watching a video on https://www.youtube.com or https://www.netflix.com.
  • Online shopping: buying a book on https://www.amazon.com or https://www.daraz.pk.
  • Social media: opening https://www.facebook.com or https://www.instagram.com in your browser.
  • Online banking: logging into your bank’s website to check your balance or pay a bill.

All of these are accessed through a web browser by typing or clicking a URL.

Key Features of the WWW
