Business and Tech Leaders

Sabeer Bhatia co-founded Hotmail with Jack Smith in 1996. Hotmail was one of the first webmail services and was later acquired by Microsoft. This is a well-established fact in tech history.

Bill Gates is the co-founder and former CEO of Microsoft Corporation, NOT Yahoo, Apple, or Satyam Computers. He built Microsoft into the world's largest software company and is one of the best-known entrepreneurs in technology.

Steve Ballmer served as CEO of Microsoft from 2000 to 2014. In 2011, he was the chief executive, succeeding Bill Gates and preceding Satya Nadella. Jerry Yang co-founded Yahoo, Farhat Jamal is not associated with Microsoft, and Wilbur Ross is an investor.

ARPANET (Advanced Research Projects Agency Network) was designed by Robert Kahn along with Vinton Cerf. Kahn is often credited as the primary designer of ARPANET's architecture, and both Kahn and Cerf later developed the TCP/IP protocols that became the foundation of the modern Internet.

Charles Babbage is widely regarded as the 'father of the computer' for his design of the Analytical Engine (1837) and Difference Engine (1822) - the first mechanical general-purpose computers. Though his machines were never fully built in his lifetime, his concepts established the fundamental architecture of modern computers.

Tim Berners-Lee invented HTML (HyperText Markup Language) in 1989-1990 while working at CERN, and this invention directly led to the creation of the World Wide Web. HTML provides the structural foundation for web pages, allowing documents to be linked through hyperlinks. Berners-Ley also created the first web browser and web server, establishing the fundamental protocols that power the modern internet.

Steve Jobs co-founded Apple Computer Company (now Apple Inc.) in 1976 along with Steve Wozniak and Ronald Wayne. Jobs provided the business vision and marketing expertise that transformed Apple from a garage startup into one of the world's most valuable companies. While Jobs co-founded Apple, he is often singularly credited in popular accounts for the company's founding, though Wozniak designed the early Apple computers.

Warren Buffett is the CEO and Chairman of Berkshire Hathaway, a multinational conglomerate holding company. Option C has a typo but is clearly the intended answer.

Mark Zuckerberg founded Facebook in 2004 while at Harvard University. Sergey Brin co-founded Google, Steve Jobs co-founded Apple, and Paul Allen co-founded Microsoft - none of these started Facebook.

Warren Buffett announced in 2006 that he would donate approximately $37.4 billion (the majority of his fortune) to the Bill and Melinda Gates Foundation, making it the largest charitable donation in history at that time. This pledge was to be fulfilled gradually through annual donations of Berkshire Hathaway shares. Steve Jobs, David Trump (likely a distractor name), and Ingvar Kamprad (IKEA founder) did not make such announcements.

Jean-Baptiste Say, a French economist, formulated the famous principle 'Supply creates its own demand' known as Say's Law. This classical economic theory states that the act of producing goods generates income equivalent to the value of the production, thereby creating demand for other goods in the economy.

Roland Junck served as CEO of ArcelorMittal during a transitional period following the merger of Arcelor and Mittal Steel Company. The question tests knowledge of corporate leadership in major global steel companies during the mid-2000s consolidation phase.

Rajat Gupta was indeed McKinsey's managing director, Arun Sarin served as Vodafone CEO, and Arun Netravali led Bell Labs. However, Rajesh Hukku was associated with i-flex Solutions (Oracle Financial Services), not IBM, making this the incorrect corporate-CEO pair.

The Bill & Melinda Gates Foundation was established by Bill Gates (Chairman of Microsoft Corporation) and his then-wife Melinda Gates in 2000. It is one of the world's largest private foundations and focuses on global health, including significant grants for AIDS/HIV research, treatment, and prevention programs worldwide.
