18.9. Common Network Programming Errors

Try these first

1. 1.

   What is a port conflict in network programming?

   Hint

   Think about what happens when two people try to enter through the same door.

2. 2.

   What does blocking I/O mean?

   Hint

   Consider how waiting stops everything else in a queue.

3. 3.

   What typically causes a port conflict?

   • Multiple applications using the same port
   • A single application using multiple ports
   • Network speed issues

   Hint

   Think about sharing an entrance with several groups trying to go through simultaneously.

4. 4.

5. 5.

   Design a networking application that minimizes the chances of port conflicts. Describe your approach.

   Hint

   Consider how well-known ports differ from dynamic ports in your design.

6. 6.

   Develop a strategy for handling packet loss in a video streaming application.

   Hint

   Think about how real-time applications require immediate data transmission but can tolerate some delays.
