In Layman’s Terms:

The Internet is a vast network that connects millions of computers around the world, allowing them to communicate with each other. It’s like a giant web of roads and highways that links different cities and countries, enabling the exchange of information, emails, videos, and other types of data.

In Technical Terms:

The Internet is a global system of interconnected computer networks that use the Internet Protocol (IP) suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks, ranging from local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.
