The internet, also known as the "net," is a global system of interconnected computer networks that use the Internet Protocol (IP) to communicate between devices. How does the Internet work? Here's a simplified overview: 1. Devices connect: Computers, smartphones, and other devices connect to the internet through internet service providers (ISPs) or cellular networks. 2. Data transmission: When you send data (e.g., emails, requests, or messages), your device breaks it into small packets and assigns IP addresses to each packet. 3. Packet routing: These packets are routed through multiple servers and networks, using IP addresses to guide them to their destination. 4. Data reception: The packets arrive at their destination, where they're reassembled into the original data. Key Internet Technologies 1. TCP/IP (Transmission Control Protocol/Internet Protocol): The fundamental protocols governing internet communication. 2. HTTP (Hypertext Transfer Protocol): The protocol for transferring web pages and other content over the internet. 3. DNS (Domain Name System): Translates domain names into IP addresses, making it easier to access websites. Internet Services 1. World Wide Web (WWW): The web, accessed through browsers like Google Chrome, Firefox, or Safari. 2. Email: Electronic mail, allowing users to send and receive messages. 3. File Transfer Protocol (FTP): A protocol for transferring files between devices. 4. Social Media: Platforms like Facebook, Twitter, and Instagram for social interaction and content sharing.
