 Internet / WWW / HTTPS / URL 

The Internet is a vast worldwide network of linked computers that enables communication between devices. It was originally developed in the late 1960s by the U.S. Department of Defense through a project called ARPANET, led by researchers such as Vint Cerf and Bob Kahn. The goal was to create a decentralized communication system that could still function during outages or attacks during the Cold War. At first, the Internet was mainly used by researchers and universities to share data and messages. Today, it supports almost every aspect of life, including communication, education, entertainment, banking, and healthcare. 

The World Wide Web (WWW) is not the same thing as the Internet, but it is a part of it. It was invented in 1989 by Tim Berners-Lee, a British computer scientist working at CERN, an international scientific organization. His goal was to make it easier for scientists to share and access documents using hyperlinks. Originally, the Web consisted of simple text-based pages viewed through basic browsers. Today, it includes interactive websites, social media platforms, streaming services, and complex web applications that shape how people access information.

The Internet and the World Wide Web are closely connected,but they are not the same thing. The Internet is the physical networks, cables, and servers, while the Web is a service that uses those things to display information through websites. They work together; without the Internet, the Web would not exist, and without the Web, the Internet would be way less accessible to everyday users.

The first website was created in 1991 by Tim Berners-Lee. It explained what the World Wide Web was and how to use it. This website is still online today. The original site can be accessed at http://info.cern.ch, and it shows how simple early web pages were compared to modern websites.

URL stands for Uniform Resource Locator. It is the address used to locate resources on the Web, such as websites or files. HTTPS is a secure version of HTTP that encrypts data exchanged between a user’s browser and a website, protecting sensitive information like passwords and payment details. URLs and HTTPS work together to ensure users are directed to the correct location on the Web while keeping communication private and secure.

Wi-Fi / Bluetooth / Lamarr / VoIP

Hedy Lamarr was a famous actress and inventor. During World War II, she helped invent a frequency-hopping communication system with George Antheil to prevent radio signals from being jammed. This concept later became the foundation for technologies such as Wi-Fi and Bluetooth. Jeff Beck and Johnny Depp wrote the song "This is a Song for Miss Hedy Lamarr". The song is about how Hedy Lamarr’s brains were overlooked by her beauty.

Bluetooth was developed in 1994 by Ericsson, a Swedish telecommunications company. It was named by Jim Kardach, inspired by the Viking king Harald “Bluetooth” Gormsson, who united Denmark and Norway, symbolizing how Bluetooth unites devices. The Bluetooth logo combines the Nordic letters for H and B, representing Harald Bluetooth’s initials.

Wi-Fi was developed in 1997 by the IEEE 802.11 committee as a way to enable wireless local area networking. Vic Hayes is known as the 'father of Wi-Fi' for leading the creation of the 802.11 standards. Wifi was technically originally called IEEE 802.11, but was not very consumer-friendly. A branding company later coined the term Wifi, which is short for “Wireless Fidelity”. Wi-Fi has since become one of the most essential technologies for everyday Internet access.

VoIP stands for “Voice over Internet Protocol” and it was invented in the mid-1990s by VocalTec. It allows voice communication to take place over the Internet instead of traditional phone lines. VoIP converts voice into digital data packets, enabling services like FaceTime, Zoom, and WhatsApp. Without VoIP technology, real-time calling and video conferencing on the internet would not be possible.
