Answers and explanations

  1. Question: What is the term for computing that uses quantum bits with superposition?
    Answer: Quantum computing
    Explanation: Quantum computing uses quantum bits (qubits) that can exist in superpositions of 0 and 1, enabling certain calculations to be done much faster than classical computers; interestingly, quantum algorithms like Shor’s can factor large numbers exponentially faster, which has big implications for cryptos
  2. Question: Which of the following best describes the primary function of a compiler?
    Answer: Translate source code to machine code
    Explanation: A compiler converts high-level source code (like C or Java) into machine code or an intermediate form so the computer can execute programs efficiently. Fun fact: some compilers also optimize code to run faster or use less memory, which can significantly improve performance.
  3. Question: Why did Moore's Law slow down in the 2010s for transistor scaling?
    Answer: Physical and economic limits
    Explanation: By the 2010s, shrinking transistors faced fundamental physical limits (quantum tunneling, heat dissipation) and rapidly rising manufacturing costs, making continued density gains impractical; this is important because it shifted the industry toward new architectures, materials, and system-level创新 to
  4. Question: Who is credited with inventing the World Wide Web in 1989?
    Answer: Tim Berners-Lee
    Explanation: Tim Berners-Lee, a British computer scientist, proposed the World Wide Web in 1989 while at CERN; he created the first web browser and server, enabling information to be linked across the internet. Fun fact: he later founded the World Wide Web Consortium (W3C) to develop web standards and has long l
  5. Question: What does ‘HTTP’ stand for in web addresses?
    Answer: HyperText Transfer Protocol
    Explanation: HTTP is the set of rules web browsers and servers use to request and deliver web pages and resources. Fun fact: HTTPS is the secure version that encrypts data using TLS to protect privacy and prevent tampering.
  6. Question: Which technology uses neural networks to generate images from text prompts?
    Answer: Diffusion models
    Explanation: Diffusion models are a class of generative AI that use neural networks to iteratively transform random noise into detailed images based on text prompts; they're behind many modern text-to-image systems. Fun fact: early diffusion techniques were inspired by thermodynamics and gradually 'denoise' an画像
  7. Question: What is the primary purpose of a blockchain in cryptocurrencies?
    Answer: Decentralized ledger
    Explanation: A blockchain's primary purpose is to act as a decentralized, tamper-resistant ledger that records transactions across a distributed network. This ensures transparency and trust without a central authority; for example, Bitcoin's blockchain prevents double-spending by having many nodes validate each
  8. Question: Which company released the first iPhone in 2007?
    Answer: Apple
    Explanation: Apple released the first iPhone in 2007, revolutionizing smartphones with its multi-touch interface and App Store ecosystem. Fun fact: the original iPhone lacked third-party apps at launch — developers used web apps until the App Store debuted in 2008.
