Ada Lovelace
first computer programmer
Ada Lovelace was a British mathematician widely regarded as the first computer programmer in history. In 1843, she published a series of notes on Charles Babbage’s Analytical Engine, in which she described the first algorithm intended to be processed by a machine. She was also the first to understand that a machine could manipulate symbols and information, not just perform numerical calculations. Although the Internet did not yet exist, Ada Lovelace laid the conceptual foundations of software and programming, which are essential to computers, digital networks, and the Web.
- 1815 – Birth of Ada Lovelace
- 1843 – Publication of the first computer algorithm
- 1852 – Death of Ada Lovelace.

Vinton Cerf & Robert Kahn
American computer scientists
In 1974, they proposed the TCP/IP protocols (Transmission Control Protocol / Internet Protocol), designed to allow different networks to communicate with one another. In 1983, TCP/IP became the official standard for ARPANET, marking the birth of the modern Internet. TCP/IP enabled the creation of a global, interoperable network of networks. This universal communication standard made it possible for the Internet to scale worldwide and later support applications such as email, the World Wide Web, and cloud services.
- 1943 – Birth of Vinton Cerf
- 1938 – Birth of Robert Kahn
- 1974 – Publication of the TCP/IP model
- 1983 – Official adoption of TCP/IP on ARPANET
Commercialization of the Internet
commercial and public platform
In 1995, the U.S. government fully privatized the Internet, allowing commercial ISPs and online businesses to operate freely. Companies like Amazon and eBay were founded, offering online services and e-commerce to the general public. The commercialization of the Internet accelerated its growth and accessibility, turning it into a global marketplace and communication platform. It laid the foundation for the digital economy, online services, and the widespread adoption of the Web.
- 1995 – Full commercialization of the Internet in the U.S.
- 1995 – Founding of early online businesses (Amazon, eBay) ARPANET
Ray Tomlinson
inventor of networked email
In 1971, while working on ARPANET, he sent the first electronic mail between two networked computers. He also introduced the use of the “@” symbol to separate the user name from the destination machine, a convention still used today. Email was the first widely adopted Internet application, proving the practical value of computer networks for human communication. It played a crucial role in accelerating the adoption of ARPANET and later the Internet, shaping how people communicate online.
- 1941 – Birth of Ray Tomlinson
- 1971 – First networked email sent
- 2016 – Death of Ray Tomlinson
Alan Turing
mathematician and logician
Turing’s work provided the mathematical foundation for programmable computers, which are essential to digital communication networks. His theories made it possible to design machines capable of executing algorithms, a prerequisite for the development of computers, networking technologies, and ultimately the Internet and the Web. Alan turing had a huge impact during the world war II and his work might have shortened the war by couples of years unfortunatly society didn't deserve him.
- 1912 – Birth of Alan Turing
- 1936 – Publication of the Turing Machine concept
- 1954 – Death of Alan Turing
Web 2.0
World Wide Web
Around 2004, platforms like Facebook, YouTube, and Wikipedia popularized the idea of the Web as a participatory medium. Users could create, share, and interact with content directly, rather than just consuming information. Web 2.0 transformed the Internet from a static information repository into a dynamic social and collaborative space. It enabled social media, online communities, and digital collaboration, shaping modern communication, media, and commerce.
- 2004 – Emergence of social media platforms and Web 2.0 concept
- Mid-2000s – Rapid growth of user-generated content and online collaboration
Mosaic
First used web browser
Released in 1993, Mosaic allowed users to view text and images within the same page and navigate the Web through a simple graphical interface. This represented a major shift from text-based browsing to a more visual and intuitive experience. Mosaic played a crucial role in the popularization of the World Wide Web. By making the Web accessible to non-technical users, it triggered rapid public adoption and directly influenced the development of future browsers such as Netscape Navigator and Internet Explorer.
- 1993 – Release of Mosaic
- 1994 – Emergence of commercial web browsers inspired by Mosaic
Tim Berners-Lee
British computer scientist
In 1989, while working at CERN, he proposed a system to share and access information over the Internet using hypertext. By 1991, he had created the core technologies of the Web: HTML, HTTP, and URLs, as well as the first web server and website. Tim Berners-Lee transformed the Internet from a technical network into a global information space accessible to everyone. The World Wide Web enabled easy navigation between documents and laid the foundation for modern websites, online services, and digital culture.
- 1955 – Birth of Tim Berners-Lee
- 1989 – Proposal of the World Wide Web
- 1991 – First website goes online
Arpanet
large-scale computer network
In 1969, ARPANET successfully connected four university research centers in the United States. It demonstrated that computers could communicate over long distances by breaking data into packets, a revolutionary approach at the time. ARPANET is considered the direct ancestor of the Internet. Its architecture proved that decentralized networks were reliable and scalable, paving the way for modern networking protocols and global digital communication.
- 1966 – ARPANET project initiated
- 1969 – First successful network connection
- 1983 – Transition to TCP/IP (integration into the modern Internet)
Domain Name System
naming system
DNS was designed by Paul Mockapetris in 1983 and officially implemented in 1984. It replaced the centralized hosts file system, allowing the Internet to scale efficiently as it grew. DNS made the Internet user-friendly and scalable. By enabling people to access websites using memorable names instead of numerical addresses, it played a crucial role in the expansion of the Web and the widespread adoption of Internet services.
- 1983 – Design of the Domain Name System
- 1984 – First implementation of DNS
- Late 1980s – Introduction of top-level domains (.com, .org, .edu)
AI, Semantic Web, and the Internet of Things

AI: Advanced algorithms enable machines to analyze large datasets, generate content, and support decision-making. Semantic Web: Efforts to structure data so that computers can “understand” and link information across sources. IoT: Everyday objects—from fridges to cars—are connected to the Internet, communicating and exchanging data automatically.
