Business and Tech Leaders

Yahoo was founded by David Filo and Jerry Yang in January 1994 while they were graduate students at Stanford University. They originally created 'Jerry and David's Guide to the World Wide Web' which later became Yahoo. Option C lists internet pioneers Vint Cerf and Robert Kahn who developed TCP/IP.

Fred Cohen coined the term 'computer virus' in 1983 during his graduate research at the University of Southern California. McAfee, Norton, and Smith are all associated with antivirus software but did not originate the term definition.

Yahoo was founded in January 1994 by David Filo and Jerry Yang, both electrical engineering graduate students at Stanford University. They created 'Jerry and David's Guide to the World Wide Web' as a directory of websites, which later evolved into Yahoo. The other options listed are pioneers in computing and networking but not Yahoo's founders.

Dr. Fred Cohen, a doctoral student at the University of Southern California, was the first to formally define and describe the concept of a 'computer virus' in his 1983 dissertation. He demonstrated virus-like programs in an experimental environment. McAfee, Smith, and Norton are associated with antivirus software, not the original definition of viruses.

Hotmail was co-founded by Sabeer Bhatia and Jack Smith in 1996, then sold to Microsoft in 1997 for approximately $400 million. The options list three incorrect names (Genica Garvida, Hans Antolin, Alan Turing) with 'none of the above' marked correct, which is accurate since the actual founders are not listed.

Tim Berners-Lee invented HTML in 1991 at CERN as part of his creation of the World Wide Web. He wrote the first browser (WorldWideWeb, later renamed Nexus) and the first HTML specification, establishing the foundation for all modern web markup languages. The other options (Ben Lee, Paul Werk, John Versky) are fictional or misspelled names not associated with HTML's development.

PHP was created by Rasmus Lerdorf in 1994, initially as a set of Common Gateway Interface (CGI) binaries in C to maintain his personal homepage. Sanibel, Florida, and Kaushalam are unrelated distractors that did not design or build the PHP programming language.

CSS was developed and is maintained by the World Wide Web Consortium (W3C), an international standards organization for the web. Options A, B, and C appear to be made-up names and have no connection to CSS development. W3C standardizes web technologies including HTML, CSS, and other specifications.

Obvious Corporation was the startup incubator founded by Evan Williams, Biz Stone, and Jack Dorsey that developed and launched Twitter in 2006. Orkut was owned by Google, Facebook by Meta, and Hi5 was developed independently by another organization.

Richard Stallman founded the Free Software Foundation (FSF) in 1985 to support the free software movement. He created the concept of copyleft and the GNU Project. The other options (Charles Kane, Nicholas Negroponte, Larry Ellison) are technology figures but not associated with FSF.

Andy Rubin (596949) co-founded Android Inc. in 2003 and led the team at Google after the acquisition in 2005 to build the Android operating system. Rich Rubin (596947) and Mike Rubin (596948) are incorrect names, while Chris White was a co-founder but not the lead of the team.

Tom M. Yeh is the founder of the ZK framework. Mark Zuckerberg founded Facebook, Orkut Buyukkokten created Orkut, and Tom DeMarco is a software engineering consultant known for his work on structured analysis.

Android was founded in 2003 by Andy Rubin, Rich Miner, Chris White, and Nick Sears. The question correctly identifies Andy Rubin (A) and Rich Miner (C) as two of the four founders. Sergey Brin co-founded Google (which acquired Android in 2005), and Steve Ballmer was Microsoft's CEO, neither of whom were Android founders.

Jerry Yang co-founded Yahoo! in 1994 along with David Filo while they were graduate students at Stanford. Bjarne Stroustrup created C++, Reid Hoffman co-founded LinkedIn, and Eduardo Saverin co-founded Facebook. The question tests knowledge of tech company founders.

Carlos Slim Helú topped the Forbes billionaires list in 2010 with a net worth of approximately $53.5 billion, marking the first time since 1994 that an American was not in the top spot. Warren Buffett and Bill Gates (William Henry Gates III) were second and third respectively that year, while Mukesh Ambani ranked fourth among the global billionaires.
