Example 1
easyWhat is the difference between the internet and the World Wide Web (WWW)?
Solution
- 1 Step 1: The internet is the global network of interconnected computers and cables — the physical infrastructure that carries data.
- 2 Step 2: The World Wide Web is a service that runs on the internet — it consists of web pages, websites, and links accessed through browsers using HTTP/HTTPS.
- 3 Step 3: Other services also run on the internet: email (SMTP), file transfer (FTP), video streaming, online gaming. The web is just one (very popular) use of the internet.
Answer
The internet is the physical network infrastructure. The WWW is a service running on it (web pages via HTTP). Email, streaming, and gaming also use the internet.
Many people use 'internet' and 'web' interchangeably, but they are different things. The internet is the infrastructure; the web is one of many applications built on top of it.
About Internet
A global network of interconnected computer networks that communicate using standardized protocols (TCP/IP). The internet is decentralized—no single authority controls it. It connects billions of devices worldwide by routing data as packets through a shared infrastructure of cables, routers, and wireless links.
