As we conclude, here is a list of questions for you to test your knowledge of this chapter's material. You will find the answers in the Assessments section of the appendix:

1. Queues decrease design flexibility since they create a rigid definition of data transfer that must be adhered to:
   • True
   • False 
2. Queues don't work well with other abstraction techniques; they must only contain simple data types:
   • True
   • False 
3. When using queues for commands acquired from a serial port, should the queue contain exactly the same information and formatting as the underlying serialized data stream? Why?  
4. Name a reason why passing data by value into queues is easier than passing by reference.  
5. Name one reason why it is necessary to carefully consider the depth of queues in a real-time embedded system?
