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.
