Influential Figures and Innovations in the Global Information Age Quiz

The World Wide Web (WWW)

• A system for sharing information over the Internet, designed for ease of use beyond IT specialists.
• Invented by Tim Berners-Lee at CERN in 1989; public access began in 1991.
• Utilizes Hypertext Transfer Protocol (HTTP) for resource access.
• Documents are stored on web servers, accessed via web browsers using uniform resource locators (URLs).
• Primary document type is web pages formatted in Hypertext Markup Language (HTML), supporting text, images, audio, video, and scripts.
• Hyperlinks in HTML provide quick navigation to other resources, enabling web surfing and interconnected browsing.
• Web applications function as application software through web pages.

Alan Turing and Modern Computing

• Alan Turing is known as the father of modern computer science.
• Developed the concept of the universal Turing machine, foundational to computing theory.
• His codebreaking work during World War II, particularly with the Enigma machine, significantly impacted the war’s outcome.
• Introduced the Turing Test, which serves as a measure of machine intelligence and underpins artificial intelligence developments.

The Printing Press

• Invented by Johannes Gutenberg in the 15th century, facilitating mass production of written works.
• Its mechanization increased the accessibility and affordability of books, democratizing information dissemination.

Search Engines

• Google Search, created by Larry Page and Sergey Brin, transformed information access on the internet.
• Utilizes extensive web content indexing and advanced search algorithms for quick retrieval of relevant information.
