The Internet
The Internet is a vast global network connecting billions of devices, enabling communication, information sharing, and online services.
How It Works
The internet relies on a decentralized system of servers, data centers, and undersea cables.
Key protocols include:
TCP/IP: Handles data transmission.
HTTP/HTTPS: Enables web browsing.
DNS: Translates domain names (e.g.,
google.com) into IP addresses.
