Questions & Answers

Q: What is Moore's Law and how has it influenced the development of computers?

Moore's Law predicts that the number of electronic switches on a computer chip would double approximately every year, leading to faster, more powerful, and cheaper computers. This prediction has driven innovation and competition in the tech industry.

Q: How did the invention of personal computers by Apple and IBM impact society?

The introduction of personal computers in the 1970s and 1980s by companies like Apple and IBM revolutionized how people interacted with technology, bringing computing from military bases to businesses, schools, and homes.

Q: What role did Xerox PARC play in the development of modern computing?

Xerox PARC was a research center that invented key features of modern computing, including the graphical user interface, Ethernet, and laser printing. Despite these innovations, Xerox failed to capitalize on their inventions, leading to other companies like Apple benefitting from their work.

Q: How did the invention of the World Wide Web revolutionize the internet?

In 1990, Tim Berners-Lee created the World Wide Web, which democratized access to the internet and enabled millions of people to interact online, creating virtual spaces for communication, collaboration, and knowledge sharing.

Summary & Key Takeaways

• Computing has evolved rapidly since the invention of the transistor in 1947, with Moore's Law driving continuous improvements in speed and power.

• The transition from large machines to personal computers in the 1970s and 1980s revolutionized the tech industry, led by innovators like Apple, Microsoft, and Xerox PARC.

• The advent of the internet in the late 1960s and World Wide Web in 1990 democratized knowledge and created new social spaces online.
