Answers and explanations

  1. Question: What does 'CPU' stand for in a computer?
    Answer: Central Processing Unit
    Explanation: The CPU is the computer's brain that executes instructions; people often confuse it with the GPU, which handles graphics.
  2. Question: Which company created the iPhone?
    Answer: Apple
    Explanation: Apple introduced the iPhone in 2007 and changed smartphones forever; some might guess other tech giants like Samsung, which makes many phones but not the original iPhone.
  3. Question: What is the name for a program that replicates itself and spreads to other computers?
    Answer: Computer virus
    Explanation: A computer virus attaches to files and spreads; it's different from a worm, which often spreads without attaching to files.
  4. Question: Which device converts digital signals to analog for telephone lines?
    Answer: Modem
    Explanation: Modem stands for modulator-demodulator and links digital devices to analog networks; routers, by contrast, direct traffic between networks.
  5. Question: What does 'HTTP' at the start of a web address mean?
    Answer: Hypertext Transfer Protocol
    Explanation: HTTP is the set of rules for transferring web pages; HTTPS adds encryption, which many mistakenly think is a totally different protocol.
  6. Question: Which component stores data long-term even when the computer is off?
    Answer: Hard drive
    Explanation: Hard drives (or SSDs) retain data without power; RAM is fast but loses data when the power is off, a common confusion.
  7. Question: What is the name of the global system that connects computers and networks?
    Answer: Internet
    Explanation: The Internet links devices worldwide and is different from the World Wide Web, which is a collection of web pages on that network.
