The internet's journey from a military experiment to a global necessity is a testament to human innovation. This article explores the internet's transformation over the past century, highlighting technological advancements, speed improvements, accessibility, and cost variations across major countries.

1. Early Foundations (1900s–1950s)

1.1 Pre-Internet Communication

Before the internet, communication relied on telegraphs and telephones. These technologies laid the groundwork for future digital communication systems.

1.2 Conceptualizing Networked Communication

In the 1950s, scientists began exploring ways to connect computers. The idea of a global network started taking shape, setting the stage for future developments.

2. The Birth of the Internet (1960s–1970s)

2.1 ARPANET: The First Network

In 1969, the U.S. Department of Defense developed ARPANET, the precursor to the modern internet. It connected research institutions, allowing them to share information digitally.

2.2 Packet Switching and Protocols

The introduction of packet switching revolutionized data transmission. Protocols like TCP/IP were developed to standardize communication between different networks.

3. Expansion and Commercialization (1980s–1990s)

3.1 From Research to Public Use

By the 1980s, networks expanded beyond military and academic use. Commercial internet service providers (ISPs) emerged, offering dial-up connections to the public.

3.2 The World Wide Web

In 1989, Tim Berners-Lee introduced the World Wide Web, making the internet more accessible through browsers and hyperlinks. This innovation spurred rapid growth in internet usage.

4. The Broadband Era (2000s)

4.1 Transition to High-Speed Internet

The 2000s saw a shift from dial-up to broadband connections, significantly increasing internet speeds and reliability. This enabled the rise of streaming services and online gaming.

4.2 Global Internet Penetration

Internet access expanded globally, with many countries investing in infrastructure to connect rural and underserved areas. Mobile internet also gained popularity, especially in developing nations.

5. The Mobile and Wireless Revolution (2010s)

5.1 Smartphones and Mobile Internet

The proliferation of smartphones transformed internet usage, allowing people to access information on the go. Mobile applications became integral to daily life.

5.2 Advancements in Wireless Technology
