People often use the words Internet and Web as if they mean exactly the same thing.
They are closely connected, but they describe different ideas.
A useful distinction is:
The Internet is the network infrastructure that connects computers and networks.
The Web is a system of linked resources and services that uses that network.
The Web depends on the Internet, but the Internet supports more than just the Web.
A simple analogy is a road system.
The roads make travel between locations possible.
Different services can use those roads:
The road system is not the same thing as any one service using it.
Similarly, the Internet provides connectivity.
The Web is one major service that uses that connectivity.
The analogy is limited, but it helps separate the infrastructure from one application built on top of it.
The Internet is a global network of interconnected networks.
Devices and networks use agreed-upon communication technologies to exchange information across those connections.
Your device may reach the Internet through:
The exact path between two systems can involve many networking devices and links.
You do not need to trace the full network path in this module.
The important idea is that the Internet provides the underlying connectivity.
When you use the Web, you commonly interact with:
For example, you enter a web address into a browser.
The browser communicates with a server.
The server responds with information.
The browser interprets that information and displays a page.
That interaction uses the Internet as the communication network.
A browser such as a desktop or mobile browser acts as a client.
The client requests web resources.
A server provides responses.
This client/server relationship is central to understanding what happens when you visit a website.
The next Learning Activities follow that interaction more closely.
It is common to say:
The website is on the Internet.
That phrase is convenient, but it can hide the technical relationship.
Website resources are stored on systems that can be reached through networks.
The Internet provides the connectivity used to reach those systems.
The Web provides the conventions used to request, identify, transfer, and display web resources.
The Internet can carry many forms of network communication.
The Web is one of them.
This is why:
Internet = Web
is too broad.
The Web depends on Internet connectivity, but not every Internet-based communication is a webpage.
In the previous activities, you worked with:
Those artifacts become useful to a learner because a browser can retrieve and render web content.
The network connection underneath that interaction belongs to the Internet side of the story.
A simple view is:
Internet
provides network connectivity
↓
Web
uses that connectivity to exchange web resources
↓
Browser
interprets resources such as HTML and CSS
↓
Visible webpage
Ask:
How can devices communicate across connected networks?
That points toward the Internet.
Ask:
How does a browser request and display a webpage?
That points toward the Web.
Ask:
How is the page content structured?
That points toward HTML.
Ask:
How is the page presented visually?
That points toward CSS.
Separating these layers makes the overall system easier to reason about.
Keep this concise relationship in mind:
Internet: the connected network infrastructure.
Web: a system of resources and communication that operates using that network.
The next activity focuses on the browser as the client in that web interaction.
