The invention of internet :

The history of the Internet goes back to the days of the development of the first communications networks. The idea of a new computer network, allowing users of differents computer to communicate, developed by many successive stages.

Unlike technologies such as the light bulb or the telephone, the Internet has no single “inventor.” Instead, it has evolved over time. The Internet got its start in the United States more than 50 years ago as a government weapon in the Cold War. For years, scientists and researchers used it to communicate and share data with one another. Today, we use the Internet for almost everything, and for many people it would be impossible to imagine life without it.

However Tim Bernes-Lee created the World Wide Web in 1989. We can therefore consider him as the creator of the Internet.

39% of the world’s population is online today, and 60% of those people use the Internet for at least 3 hours per day.

Arpanet was the network that became the basis for the Internet. Based on a concept first published in 1967, ARPANET was developed under the direction of the U.S. Advanced Research Projects Agency (ARPA). In 1969, the idea became a modest reality with the interconnection of four university computers. The initial purpose was to communicate with and share computer resources among mainly scientific users at the connected institutions. ARPANET took advantage of the new idea of sending information in small units called packets that could be routed on different paths and reconstructed at their destination. The development of the TCP/IP protocols in the 1970s made it possible to expand the size of the network, which now had become a network of networks, in an orderly way.

Ethernet is the most widely installed local area network (LAN) technology. Ethernet is a link layer protocol in the TCP/IP stack, describing how networked devices can format data for transmission to other network devices on the same network segment, and how to put that data out on the network connection. It touches both Layer 1 (the physical layer) and Layer 2  (the data link layer) on the OSI network protocol model. Ethernet defines two units of transmission, packet and frame. The frame includes not just the "payload" of data being transmitted but also addressing information identifying the physical "Media Access Control" (MAC) addresses of both sender and receiver, VLAN tagging and quality of service information, and error-correction information to detect problems in transmission. Each frame is wrapped in a packet, which affixes several bytes of information used in establishing the connection and marking where the frame starts.

The Web, or World Wide Web (W3), is basically a system of Internet servers that support specially formatted documents. The documents are formatted in a markup language called HTML (HyperText Markup Language) that supports links to other documents, as well as graphics, audio, and video files.

This means you can jump from one document to another simply by clicking on hot spots. Not all Internet servers are part of the World Wide Web.

Internet ecosystem is the term used to describe the organizations and communities that help the Internet work and evolve.  These organizations share common values for the open development of the Internet.  The Internet Ecosystem term implies that the rapid and continued development and adoption of Internet technologies can be attributed to the involvement of a broad range of actors; open, transparent, and collaborative processes; and the use of products and infrastructure with dispersed ownership and control.
There are technologists, engineers, architects, creatives, organizations (global or local), operators, vendors or also internet users (personal), educators and policy and decision makers.
The Internet is successful in large part due to its unique model: shared global ownership, open standards development, and freely accessible processes for technology and policy development. The Internet’s unprecedented success continues to thrive because the Internet model is open, transparent, and collaborative.  The model relies

on processes and products that are local, bottom-up and accessible to users around the world.
