Histoire de la mondialisation d'internet en 40 cartes

Histoire de la mondialisation d'internet en 40 cartes
The internet increasingly pervades our lives, delivering information to us no matter where we are. It takes a complex system of cables, servers, towers, and other infrastructure, developed over decades, to allow us to stay in touch with our friends and family so effortlessly. Here are 40 maps that will help you better understand the internet — where it came from, how it works, and how it's used by people around the world. How the internet was created Before the internet, there was the ARPANET Before the internet, there was the ARPANETARPANET, the precursor to the modern internet, was an academic research project funded by the Advanced Research Projects Agency, a branch of the military known for funding ambitious research projects without immediate commercial or military applications. Initially, the network only connected the University of Utah with three research centers in California. The internet around the world Threats to the internet The geography of online services Twerking vs.

Débats : dodo internet et inégalités accès mondiale Scientists track Internet usage as it pulses across the globe daily Contact: Robert Perkins at (213) 740-9226 or perkinsr@usc.edu Researchers studying how big the Internet is have found that it “sleeps,” almost like a living creature. The finding will help scientists and policymakers develop better systems to measure and track Internet outages, such as those that struck the New York area after Hurricane Sandy. facebook_experiments_on_users_they_ve_got_more_in_store Photo illustration. Photo by Michael Dalder/Reuters. Facebook and two outside social scientists recently published a scientific paper in which they revealed that they had manipulated users’ news feeds to tweak their emotions. Since then, there has been a growing debate over the ethics and practice of Facebook experimenting on its users, as chronicled by Slate’s Katy Waldman. In response to these concerns, this morning Facebook issued the following press release—although I seem to be the only journalist who has received it. Coming hot on the heels of Facebook’s carefully unapologetic defense of its emotion research on its users, I share the press release as a glimpse of Facebook’s future directions in its user experiments.

Territorial map of the world Today, we are beginning to envision the world as a continuous space where the movement of people and information overrides geographical and political barriers. This political map of the world depicts the extent of territories, both on land and at sea (submerged lands), which are under the control of all independent nations. The map incorporates Exclusive Economic Zones (EEZ), which are sea zones whose resources belong to their coastal-lying nations. International law defines these zones as lying within a 200 nautical miles geometrical offsetting of the coast seawards, and, where these geometrical boundaries prove ambiguous, through international treaties.[1] Throughout the development of sea voyage and charting technology, coastlines, historically mapped as linear entities dividing land from water, became one of the first geographical features to be accurately represented in maps, thus becoming a common datum for exploration.

History of Computers and Computing, Internet, Birth, Paul Baran Paul Baran Three people can be credited as inventors of packet-switched networks, thus laying foundations for Internet: Paul Baran, Leonard Kleinrock and Donald Davies. Paul A. Baran was born in the town of Grodno (then in Poland, now in Belarus) as Павел Баранов (Yiddish given name "Pesach", one of the most commonly observed Jewish holidays, usually in April) on April 29, 1926, as the youngest of three children in a Jewish family. In May, 1928, his family moved to the United States, first in Boston, then in Philadelphia, where his father—Morris "Moshe" Baran (1884–1979) owned a small grocery store. As a child, Baran delivered groceries for his father in his little red wagon.

Transmission Control Protocol Web browsers use TCP when they connect to servers on the World Wide Web, and it is used to deliver email and transfer files from one location to another. HTTP, HTTPS, SMTP, POP3, IMAP, SSH, FTP, Telnet and a variety of other protocols are typically encapsulated in TCP. Historical origin[edit] In May 1974 the Institute of Electrical and Electronic Engineers (IEEE) published a paper titled "A Protocol for Packet Network Intercommunication.

Video Shows Every Flight on Earth in 72 Seconds Aspiring scientists from the Zurich School of Applied Sciences have built a video simulation that displays the flight path of every commercial flight in the world over a 24-hour period. There isn’t much of an application for it, but it sure is cool to look at. While the map may look complex, Dr. Karl Rege tells us he and his team found it surprisingly simple to assemble using data readily available on the internet.

Everything We Know About Facebook's Secret Mood Manipulation Experiment - Robinson Meyer It was probably legal. But was it ethical? Updated, 09/08/14 Facebook’s News Feed—the main list of status updates, messages, and photos you see when you open Facebook on your computer or phone—is not a perfect mirror of the world. But few users expect that Facebook would change their News Feed in order to manipulate their emotional state.

40 more maps that explain the world Maps seemed to be everywhere in 2013, a trend I like to think we encouraged along with August's 40 maps that explain the world. Maps can be a remarkably powerful tool for understanding the world and how it works, but they show only what you ask them to. You might consider this, then, a collection of maps meant to inspire your inner map nerd. I've searched far and wide for maps that can reveal and surprise and inform in ways that the daily headlines might not, with a careful eye for sourcing and detail. I've included a link for more information on just about every one. Enjoy.

Internet Protocol This article is about the IP network protocol only. For Internet architecture or other protocols, see Internet protocol suite. The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.
