Cause of bind() Error

Question Text

While receiver.py is still running, run it again from another terminal. You will get an error. What is its cause?

Question Answers

• the IP 127.0.0.1 is already used by receive.py

• the port 5000 is already used (by receive.py)

• a port may not be used multiple times by the same process

• the socket was not created correctly

Feedback

One port may only be bound to one socket at a time. The fact that it’s the same program (same source code) using it is irrelevant because they’re different processes.
