The internet’s history is the story of the evolution of interconnected computer networks, starting with the US military’s ARPANET in the 1960s and culminating in the global network we use today. It’s a continuous process of innovation and expansion.
Key Characteristics / Core Concepts
- ARPANET (Advanced Research Projects Agency Network): The precursor to the internet, a decentralized network designed for military communication and research.
- TCP/IP (Transmission Control Protocol/Internet Protocol): The foundational communication protocols that enable data transmission across diverse networks.
- The World Wide Web (WWW): A system of interconnected hypertext documents accessed via the internet, introducing a user-friendly interface.
- Decentralization: The internet’s design resists control by a single entity, making it resilient and adaptable.
- Continuous evolution: The internet is constantly changing, evolving with new technologies and applications.
How It Works / Its Function
The internet works by connecting countless computers and devices through a network of networks. Data is sent in packets, guided by TCP/IP, across this network using various physical connections like fiber optic cables and satellites. The World Wide Web provides a way to access and share information in a visually appealing manner.
Examples
- ARPANET’s first message: “Lo,” sent in 1969, demonstrated the basic communication capabilities.
- The creation of the World Wide Web in the late 1980s revolutionized information access and sharing.
- The dot-com boom of the late 1990s showcased the rapid commercialization and growth of the internet.
Why is it Important? / Significance
The internet has profoundly impacted nearly every aspect of modern life. It revolutionized communication, commerce, information access, and global connectivity. Its influence continues to shape culture, society, and technology.
