Introduction to the Web
What Is the Internet?
The Internet is a global network of connected computers and devices that communicate using standardized protocols. It isn't a single physical object. It's a worldwide infrastructure made of cables, routers, switches, fiber-optic lines, satellites, and more.
In simple terms, a network of networks that allows information to move across the world.
How does the Web Work?
The World Wide Web (WWW) is a part of the Internet. It's a system of linked documents and resources connected through hyperlinks and URLs. The web uses a client-server model:
Clients
Devices like computers, phones, or tablets. Web browsers (Chrome, Firefox, Safari) run on these devices and display web pages.
Servers
Powerful computers that store and provide web content. When you enter a URL or click a link, your browser (the client) sends a request to the server. The server then sends the requested page back to the browser.
1. What is the Internet?
2. What are clients in the context of the web?
3. When a user (client) requests a web page, what happens next?
