Internet / World Wide Web / Wi-Fi / Bluetooth

 Internet / WWW

  • The internet is a global network of interconnected computers network, and these use "standardized communication" protocols to connect all these different devices worldwide. The internet was not founded by an individual. It was founded by different people who contributed to create it. Some of them are: ARPANET (1960s), TCP/IP (1970s).
  • The internet was primarily used for research, academic collaboration, and military purposes. On the other hand, today the internet is used for different purposes such as communication (email, social media, video conferencing), information access (search engines, online encyclopedias), entertainment (streaming services, online gaming), e-commerce, education, and more.
  • World Wide Web is a system of interconnected documents and resources, whose are linked through hyperlinks and URLs (Uniform Resource Locators). This web gives users the access for different content such as multimedia, text, images, videos, and different kind of applications. World Wide Web (WWW) was founded in 1989 by Tim Berners-Lee. Tim is a British computer scientist that worked at CERN (The European Organization For Nuclear Research). The main purpose of this creation was to facilitate information sharing among scientists whose were working on different experiments.
  • The internet and WWW are not the same. As mentioned earlier, the Internet is the global infrastructure, while the World Wide Web is a system of interconnected documents and resources that exist on the Internet. In other words, the World Wide Web needs the internet to exist. They work together, since the WWW is one of the services that internet offers, and it relies on the internet to deliver data to users.
  • The first website was created in 1990 by Tim Berners-Lee, but it was not a public website. The first public website was created in 1991, which was basically an introduction to the World Wide Web. The original website is no longer available, but CERN recreated it. It can be found athttp://info.cern.ch](http://info.cern.ch).

Wi-Fi / Bluetooth and Lamarr

Hedy Lamarr and her Connection to WiFi and Bluetooth:

  • Hedy Lamarr was an Austrian-American actress and inventor. While she is not directly connected to the development of Wi-Fi and Bluetooth, her work in the field of wireless communication technology had a significant impact on their development. Although the technology was not widely adopted during the war, it laid the foundation for modern wireless communication, including technologies like Wi-Fi and Bluetooth. There is a song that Johnny Deep wrote highlighting Lamarr's beauty, as the website Auralcrave states "Hedy Lamarr was a genius, imprisoned in the appearance of a movie diva. Her beauty became the cage that prevented the world to take seriously her genie". 

Bluetooth

  • Bluetooth technology was developed in the 1990s, with key contributions from engineers at Ericsson, a Swedish telecommunications company. Its name, "Bluetooth," draws inspiration from the 10th-century Danish king, Harald "Bluetooth" Gormsson, known for uniting various tribes in Denmark and parts of Norway. The choice of this name symbolizes the goal of uniting diverse communication devices. The Bluetooth logo creatively combines Nordic runes representing the initials "H" and "B," emphasizing the theme of unification associated with King Harald Bluetooth.

Wi-Fi (Wireless Fidelity):

  • Wi-Fi technology was developed in the late 1990s by a group of engineers and scientists associated with the Institute of Electrical and Electronics Engineers (IEEE). Its primary purpose was to enable wireless connectivity for computer networks, eliminating the need for physical cables to connect devices to the Internet.

Originally known as "IEEE 802.11," the technical name was not user-friendly. To make the technology more accessible to the public, the term "Wireless Fidelity" was coined as a marketing slogan. Over time, "Wi-Fi" became the widely adopted term for wireless Internet access.

The Wi-Fi logo, commonly seen on wireless devices, is not an acronym but rather a design element representing wireless connectivity. While it doesn't stand for anything specific, it serves as a recognizable symbol for wireless networking.
