1.1 What is the Internet?
1.2 What is the Web?
The World Wide Web, commonly known as the Web, is a vast system of interconnected digital content accessible through the Internet. It is an information space where documents and resources are identified by Uniform Resource Locators (URLs) and can be accessed via browsers. The web is built on the foundation of hypertext, allowing users to navigate between documents, often linked through hyperlinks. Tim Berners-Lee, credited with the invention of the World Wide Web in 1989, envisioned it as a decentralized platform for sharing information globally. The web encompasses a multitude of websites, web pages, multimedia content, and interactive applications, forming a dynamic and ever-expanding virtual environment. It serves as a conduit for diverse activities, from communication and commerce to education and entertainment, profoundly influencing how individuals interact with information in the digital age. The World Wide Web has become an integral component of our daily lives, connecting people across the globe and providing an unparalleled platform for exchanging knowledge and ideas.
1.3 How does the Internet work?
The Internet functions as a vast and intricate network of interconnected computers and devices operating on standardized protocols that facilitate the seamless exchange of information. At its core, the Internet relies on a global infrastructure of physical cables, fiber-optic lines, satellites, and wireless connections, forming an extensive network of networks. Data transmission is governed by protocols like TCP (Transmission Control Protocol) and IP (Internet Protocol), where TCP ensures reliable delivery, and IP handles the addressing and routing of data packets. The Domain Name System (DNS) is a crucial component, translating human-readable domain names into numerical IP addresses, enabling users to access websites using familiar URLs. Following a client-server model, the interaction between servers and clients involves servers hosting content and clients requesting and receiving information. Data is transmitted in packets, small units containing both data and addressing information, which travel independently across the network and are reassembled at their destination. Routers are vital in directing data packets and analyzing destination IP addresses to determine the most efficient path. Internet Service Providers (ISPs) connect users to the broader Internet infrastructure, offering various connections. Security protocols, such as SSL/TLS, ensure data encryption during transmission, safeguarding privacy. This intricate interplay of components and processes forms the foundation of the Internet, a transformative force that has revolutionized communication, information access, and global connectivity.
