   What does API stand for?

   Hint

   Think about how applications communicate.

2. 2.

   Name one type of API.

   Hint

   Consider the roles they play in embedded systems.

3. 3.

   What does API stand for?

   • Application Process Interface
   • Application Programming Interface

4. 4.

   True or False: Hardware Abstraction APIs deal with high-level functionalities.

   • True
   • False

   Hint

   Consider the depth of the term 'abstraction'.

5. 5.

   Design an API for a simple temperature sensors system which requires functions for initialization, reading temperature, and error handling. Write pseudo-code for this API.

   Hint

   Start by considering what basic functionalities the temperature sensor requires.

6. 6.
