Which multiprocessing methods use shared memory?

[Kevin Ar18]

I'm not sure my previous message went through (I wasn't subscribe), so I'm gonna try again.

The multiprocessing module has 4 methods for sharing data between processes:
Queues
Pipes
Shared Memory Map
Server Process
 
Which of these use shared memory?
 
I understand that the 3rd (Shared Memory Map) does, but what about Queues?
 
Thanks,
Kevin
