Exam Tips - Embedded Systems

Key points to always mention:

  • "Dedicated function" is the most important phrase - embedded systems do ONE specific job
  • Compare to general-purpose: Embedded = specific task, General = many tasks
  • Use real examples: washing machine, microwave, car engine, traffic lights

Common exam questions:

  • "What is an embedded system?" → Computer with dedicated function built into a larger device
  • "Give an example" → Washing machine, car engine control, microwave (with explanation)
  • "Advantage over general-purpose?" → Smaller, cheaper, lower power, more reliable
  • "Disadvantage?" → Cannot be upgraded or repurposed for different tasks

Common mistakes:

  • Saying a smartphone is an embedded system - it's NOT (it's general-purpose!)
  • Forgetting to explain WHY it's embedded (the "dedicated function" part)
  • Not giving specific examples from everyday life
