50 Tech trivia questions
Q1. Bill Gates co-founded which technology company in 1975?
Answer: Microsoft
💡 Gates and Paul Allen founded Microsoft (originally 'Micro-Soft') to develop BASIC interpreters for the Altair 8800. The name combined 'microcomputer' and 'software.' Gates was 19.
Q2. Larry Page and Sergey Brin founded which search engine at Stanford?
Answer: Google
💡 Google began as 'BackRub,' a research project analyzing the web's link structure. The name Google is a play on 'googol' (10^100), reflecting the vast amount of data they planned to index.
Q3. What does 'Wi-Fi' stand for?
Answer: Nothing — it's just a brand name
💡 The Wi-Fi Alliance hired a marketing firm for an easy name to replace 'IEEE 802.11b Direct Sequence.' The 'Wireless Fidelity' backronym was added later but isn't the real meaning.
Q4. In what year was Facebook (now Meta) founded?
Answer: 2004

Q5. What platform is primarily associated with 280-character posts (originally 140)?
Answer: Twitter (now X)
💡 Twitter's 140-character limit was chosen to fit within SMS messages (160 chars minus username). Jack Dorsey, Biz Stone, and Evan Williams co-founded it in 2006. Elon Musk acquired it in 2022 and rebranded it X.
Q6. What does 'www' stand for in a web address?
Answer: World Wide Web
💡 Tim Berners-Lee has called 'www' 'the most pointless abbreviation in history' since the abbreviation (9 syllables) takes longer to say than what it abbreviates (3 syllables: 'web').
Q7. In 2002, this squat disc became the first robot vacuum to really catch on, priced under $200.
Answer: Roomba
💡 iRobot's original Roomba launched at $199.95 in September 2002 and sold a million units a year within three years.

Answer: QWERTY
💡 One popular theory says Christopher Sholes rearranged the keys specifically to slow typists down and stop the mechanical arms from jamming.
Q9. Instead of buying your own servers, you can rent computing power online — what's this called?
Answer: Cloud computing
💡 Cloud providers use software called a hypervisor to carve one physical server into many virtual ones for different customers.

Answer: iPod
💡 The original model worked only with Mac computers — Windows support didn't arrive until a software update the following year.
Q15. Which love-note-themed worm swept from the Philippines in May 2000, infecting 10 million PCs?
Answer: ILOVEYOU
💡 Its creator, Onel de Guzman, avoided prosecution because the Philippines had no cybercrime laws at the time.

Q32. What does 'CPU' stand for?
Answer: Central Processing Unit
💡 The first commercially available general-purpose CPU was the Intel 4004 in 1971 — a 4-bit chip with 2,300 transistors. Modern CPUs contain billions of transistors smaller than a virus.

💡 Van Rossum named Python after Monty Python's Flying Circus, not the snake. He designed it for readability and simplicity. Python is now the most popular programming language in the world.
Q35. What does 'HTTP' stand for?
Answer: HyperText Transfer Protocol
💡 HTTP is the foundation of data communication on the web. Tim Berners-Lee defined the first version in 1989. HTTPS (secure) adds TLS encryption — the padlock in your browser address bar.
Q36. What is 'open source' software?
Answer: Software whose source code anyone can inspect, modify, and distribute
💡 Linus Torvalds created Linux in 1991 as open source. The Open Source Initiative was founded in 1998 to promote the model.

Answer: Transistors on a chip roughly double every two years
💡 Gordon Moore (Intel co-founder) first predicted yearly doubling in 1965, revising it to two years in 1975. It is now slowing as transistors near atomic scale.
Q38. What was ARPANET, the predecessor to the internet?
Answer: A 1969 US Defense Department research network
💡 ARPANET was the first packet-switched network. Its first message (Oct 29, 1969) was meant to be 'LOGIN' but crashed after 'LO'.
Q39. What is 'machine learning'?
Answer: AI where systems learn patterns from data, not coded rules
💡 Arthur Samuel coined 'machine learning' in 1959 at IBM. The recent revolution is driven by deep learning — neural networks with many layers needing vast data and GPU compute.
Q40. What is a 'bug' in software?
Answer: An error or flaw in code that causes unexpected behaviour
💡 The term 'bug' predates computers — engineers used it for electrical faults. The famous 1947 Grace Hopper 'moth in the relay' is often cited as the origin, but the term was already common in engineering before that.
Q41. What is 'JavaScript' primarily used for?
Answer: Adding interactivity to websites in browsers
💡 Brendan Eich created JavaScript in 10 days in 1995 at Netscape. The name was marketing — Java was hot — but the two languages are almost entirely unrelated.
Q42. What is 'Git' primarily used for?
Answer: Version control for tracking code changes
💡 Linus Torvalds created Git in 2005 in 10 days. GitHub (2008), GitLab, and Bitbucket are web services built around Git.
Q43. What does 'API' stand for?
Answer: Application Programming Interface
💡 An API defines how different software systems communicate. When a weather app shows your local temperature, it's calling a weather service API. REST APIs using HTTP are the most common type on the web.
Q44. What is 'SQL' used for?
Answer: Managing databases
💡 SQL (Structured Query Language) was developed by IBM in the 1970s based on Edgar Codd's relational model. It was standardized in 1986 and remains the dominant language for querying relational databases.
Q45. What is 'encryption' in computing?
Answer: Encoding data so only someone with the key can read it
💡 End-to-end encryption (used by WhatsApp, Signal) means even the service provider can't read messages. Modern RSA encryption uses prime numbers so large that factoring them would take longer than the universe's age.
Q46. What does 'RAM' stand for in computers?
Answer: Random Access Memory
💡 RAM is your computer's short-term memory — fast but volatile (lost when power off). Increasing RAM typically speeds up multitasking. SSDs and HDDs are long-term storage; RAM holds what's currently running.
Q47. What is a 'transistor' and why is it fundamental to computing?
Answer: A tiny semiconductor switch that can be on (1) or off (0) — the basis of all digital computing
💡 Invented at Bell Labs in 1947 by Shockley, Bardeen, and Brattain. Modern chips contain billions. The smallest transistors (TSMC 3nm process) are smaller than a strand of DNA.
Q48. What is 'artificial intelligence' (AI)?
Answer: Computer systems that simulate human learning and reasoning
💡 The term 'artificial intelligence' was coined by John McCarthy at the 1956 Dartmouth Conference, widely considered the birth of AI as a field. McCarthy also invented the Lisp programming language.
Q49. What does 'URL' stand for?
Answer: Uniform Resource Locator
💡 A URL is a web address that identifies a resource by its location (e.g., https://example.com/page). URLs were defined by Tim Berners-Lee and Dan Connolly in 1994 and are a type of URI.
Q50. What was the first widely-used graphical web browser?
Answer: Mosaic
💡 Mosaic (1993) was developed by Marc Andreessen at the NCSA. Its ability to display images inline (not separately) made the web visually compelling for the first time, before Netscape Navigator followed.
