The World Wide Web and Commercialization
In 1989, Tim Berners-Lee, a British scientist, proposed the World Wide Web (WWW), a system of interlinked hypertext documents accessible via the internet. The introduction of web browsers in the early 1990s, such as Mosaic, made the internet more user-friendly and accessible to the general public.
The mid-1990s marked the commercialization of the internet, with the emergence of internet service providers (ISPs) and the proliferation of websites. This era saw the birth of e-commerce giants like Amazon and eBay, transforming how people shop and conduct business.
How the Internet Works
Basic Architecture
The internet operates on a decentralized network architecture, where millions of private, public, academic, business, and government networks interconnect globally. Data is transmitted in small packets across these networks using standardized protocols, ensuring reliable and efficient communication.
Key Components
- Servers and Clients: Servers host websites, applications, and data, responding to requests from client devices such as computers, smartphones, and tablets.
- Protocols: Protocols like HTTP/HTTPS (HyperText Transfer Protocol/Secure), FTP (File Transfer Protocol), and SMTP (Simple Mail Transfer Protocol) govern how data is transmitted and accessed.
- IP Addresses and DNS: Every device connected to the internet has a unique IP address. The Domain Name System (DNS) translates human-readable domain names (e.g., www.example.com) into IP addresses, facilitating easy navigation.
Data Transmission
Data travels through a series of routers and switches that direct packets to their destination. Undersea fiber-optic cables and satellite links connect continents, enabling global communication. The internet’s robustness stems from its ability to route around disruptions, maintaining connectivity even when parts of the network are compromised.
