Lesson Content/Board Summary

INTRODUCTION TO THE WORLD WIDE WEB

Meaning and Full Form of WWW

The World Wide Web, commonly known as the Web, is a global system of interconnected computer networks that uses the internet’s standard communication protocols. It is a system of interlinked hypertext documents and other web resources that are accessed via the Internet.

The full meaning of WWW is **World Wide Web**.

Brief History of the World Wide Web

The World Wide Web was invented by **Sir Tim Berners-Lee** in **1989** while he was working at CERN (European Organization for Nuclear Research) in Switzerland. His original purpose was to create a system for scientists to easily share information and research documents across different computer systems. He developed the first web browser and web server in 1990, and the Web was made publicly available in 1991.

Basic Terminologies of the World Wide Web

Understanding the WWW involves several key terms:

1. World Wide Web (WWW): A global information system that users can access via the Internet. It consists of all public websites and web resources.
2. Website: A collection of related web pages, images, videos, and other digital assets that are hosted on a web server and accessible via a specific domain name.
3. Webpage: A single document or page of information within a website, typically written in HTML, that can contain text, images, videos, and links to other web pages.
4. Homepage: The main page of a website, which usually serves as the entry point or starting point for visitors. It often contains a table of contents or links to other sections of the site.

Common Protocols

Protocols are sets of rules that govern how data is transmitted and received over a network. Key protocols related to the WWW include:

1. HTTP (Hypertext Transfer Protocol): This is the application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, allowing users to retrieve web pages from web servers.
2. HTML (Hypertext Markup Language): This is the standard markup language for documents designed to be displayed in a web browser. It defines the structure and content of web pages.

Lesson Keywords

• WWW – World Wide Web
• Website – A collection of related web pages
• Webpage – A single document within a website
• Homepage – The main page of a website
• HTTP – Hypertext Transfer Protocol
• HTML – Hypertext Markup Language
• Berners-Lee – Inventor of the WWW

Differentiation

Support for weaker learners: Provide simpler definitions and more direct examples. Pair them with stronger students for discussion and note-taking. Offer printed notes of the Board Summary if copying is a challenge.

Extension for faster learners: Encourage them to research the difference between the Internet and the World Wide Web, or to find out about other early web browsers.
