History of the Internet
The World Wide Web vs. the Internet: What's the Difference?
The internet and the World Wide Web are related but distinct. One is the infrastructure; the other is a service that runs on it.
The internet is the network
The internet is the global system of interconnected computer networks. It is the roads, cables, routers, and protocols (chiefly TCP/IP) that let any connected device exchange data with any other. It has existed since the 1970s and 80s, long before most people had heard of it.
The Web is one thing built on the internet
The World Wide Web is a specific service that runs on the internet: a system of interlinked documents and resources, identified by URLs, transferred using HTTP, and usually viewed in a browser. It was invented around 1990. The Web is enormously important, but it is only one of many services the internet carries.
Other things that use the internet but aren't the Web
- Email uses protocols like SMTP and IMAP — older than the Web.
- Video calls and streaming often use their own protocols over the internet.
- Online games, app APIs, file transfers, and messaging may not touch the Web at all.
When your phone app talks to a server without opening a browser, it is using the internet but not necessarily the Web.
A simple analogy
Think of the internet as a country's road network, and the Web as the postal service that uses those roads. The roads existed first and carry many kinds of traffic. The postal service is one important, hugely popular thing built on top of them — but delivery trucks, buses, and ambulances use the same roads without being "the post."
Why the distinction matters
Understanding the difference clarifies a lot. Your IP address is an internet concept — it identifies your device on the network regardless of whether you are browsing the Web, sending email, or playing a game. Tools like IP Ducky report internet-level facts about your connection, which is why they work no matter what app you are using.
