These exercises were completed after watching the following YouTube video.

1. What is an embedded system?

"An embedded system is a special-purpose computer, custom-built to serve a specific purpose."

2. What is a specific purpose device or computer?

A custom-made computer, made to serve a particular function.

3. What are general purpose devices or computers?

Computers that we use every day--as in, consciously use, being aware that they are computers--, which are designed to fulfill more than one purpose.

4. Write 3 examples of specific purpose devices

  • Calculators
  • Digital wristwatches
  • Electronic typewriters

5. Write 3 examples of general-purpose devices

  • Desktop and laptop PCs
  • Smartphones and tablets
  • Smart TVs and other unnecesarily "smart" devices

6. What are the three types of embedded systems?

  • Subsystem
  • Standalone system
  • Networked system

7. Define and write two examples of every embedded system

  • Subsystem: The origin of the therm "embedded system". This one's a sub-part of another system. Two examples are:
    • A digital dashboard, embedded into a car.
    • A computerized controller, embedded into a home appliance, like a microwave oven or a washing machine's console.
  • Standalone system: The device performs its own thing, independently. Two examples are:
    • An MP3 player.
    • A digital camera.
  • Networked system: A group of physically separate electronic devices, which perform a collective function. When seen from a global perspective, this is the abomination they call the "Internet of Things". Two examples are:
    • A remotely-operated AC system.
    • A door on the front of your house, that closes in on you if it hears you say no-no words banned by Google.
