The Internet was not invented in a single moment – there were many contributions to the technology that led to what we now know as the Internet. It happened over time, with many people building and expanding upon what was there before. The things that come to mind when we think of the Internet – Wi-Fi, broadband, the World Wide Web, for example – didn’t come along until years after the first Internet-like technology was first in use.

1960s:

• ARPANET: The Advanced Research Projects Agency Network (ARPANET) was created by the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA) to connect computers at different research institutions.
• Packet Switching: Paul Baran proposed the concept of packet switching. It created more efficient transmission across a network by dividing data into packets.

1970s:

• Transmission Control Protocol (TCP): Vinton Cerf and Bob Kahn developed TCP, a protocol that allows different networks to communicate and share data, forming the basis for the Internet’s communication framework.
• Ethernet: Developed by Robert Metcalfe and David Boggs, Ethernet became a widely used local area networking (LAN) technology, allowing computers to communicate within a small area.

1980s:

• Domain Name System (DNS): The DNS was introduced to make it easier to access websites by mapping IP addresses to human-readable domain names.
• TCP/IP Standardization: On January 1, 1983, TCP/IP became the standard communication protocol for ARPANET and eventually the whole Internet, ensuring compatibility between different network systems. Many consider this date to be the “birth of the internet”.

1990s:

• Wi-Fi: In 1991, a team of researchers at NCR Corporation and AT&T Corporation, including John O’Sullivan, Terence Percival, and Diethelm Ostry, developed a wireless networking technology that would later be known as Wi-Fi. The first version of the IEEE 802.11 wireless standard was released in 1997.

• Internet of Things (IoT): Everyday objects become connected to the internet, enabling data exchange and remote control of devices.
• 5G Technology: The development and deployment of 5G networks promised even faster and more reliable wireless internet connections.

Who originally invented the Internet?

The Internet was not simply invented by one person, so to understand the origin of the Internet as we know it, it’s better to imagine a child being raised by a community. This community included people like Vinton Cerf, Bob Kahn, Tim Berners-Lee, Paul Baran, Radia Perlman, and Karen Spärck Jones to name just a few of the main players.

• Vinton Cerf and Bob Kahn: Vinton Cerf and Bob Kahn are often referred to as the “fathers of the Internet.” In the 1970s, they co-developed the Transmission Control Protocol (TCP) and the Internet Protocol (IP), collectively known as TCP/IP. This protocol suite established the fundamental rules for data transmission and communication between different computer networks. Their work was crucial in ensuring that disparate networks could interconnect and share information seamlessly.
• Tim Berners-Lee: Tim Berners-Lee, a British computer scientist, led the creation of the World Wide Web (WWW) in the late 1980s. His vision aimed to ensure that information would be readily available and effortlessly shared across the entire world. Berners-Lee developed the necessary technologies, including HTML (Hypertext Markup Language) and HTTP (Hypertext Transfer Protocol), which allowed documents to be linked and accessed through a web browser. This innovation marked the birth of the web as we know it, making it user-friendly and accessible to a broader audience.
• Paul Baran: Although not directly responsible for inventing the Internet, Paul Baran’s concept of packet switching was a critical building block. In the 1960s, Baran proposed the idea of breaking down data into smaller packets for more efficient transmission across a network. This concept laid the groundwork for the creation of the Advanced Research Projects Agency Network (ARPANET), which later evolved into the modern Internet.
• Radia Perlman: Sometimes referred to as the “Mother of the Internet,” Radia Perlman’s work on networking protocols was instrumental in the development of the Internet. She is known for her invention of the spanning-tree protocol (STP), which made Ethernet networks more reliable and scalable.
• Karen Spärck Jones: British computer scientist, Karen Spärck Jones, made significant contributions to natural language processing and information retrieval. Her work has had a profound impact on search engines and text analysis systems, which are essential components of the modern Internet.

How did the Internet begin?

The beginning of the Internet was a gradual process that involved various stages:

• Conceptualisation: The idea of a networked communication system emerges, aiming to connect computers for research and military purposes.
• ARPANET Development: The U.S. Department of Defense’s ARPANET project establishes the initial framework for interconnecting computers.
• Packet Switching: Paul Baran’s concept of packet switching becomes a crucial building block.
• TCP/IP: Vint Cerf and Bob Kahn’s development of TCP/IP protocols allows disparate networks to interconnect, forming a unified network of networks—the Internet.
• World Wide Web: Tim Berners-Lee’s invention of the World Wide Web introduced a user-friendly way to navigate and share information, leading to the Internet’s rapid expansion.

When were Broadband and Wi-Fi created?

Broadband and Wi-Fi are two cornerstones of modern Internet usage that have revolutionised how we connect and access information. The history of broadband could be an article in itself. These technologies have marked the evolution of Internet from something only in use by a select few research institutions, to a worldwide technology accessible to all.

Broadband

The term “broadband” refers to high-speed data transmission. While the concept existed early on, major progress happened in the late 1990s with two significant technologies: Digital Subscriber Line (DSL) and cable Internet. DSL repurposed phone lines for faster data transmission, while cable Internet utilised TV cable infrastructure. These breakthroughs brought faster speeds, smoother streaming, and more immersive online experiences.
