 |  | 
 | The modules described in this chapter provide mechanisms for different processes | 
 | to communicate. | 
 |  | 
 | Some modules only work for two processes that are on the same machine, e.g. | 
 | :mod:`signal` and :mod:`mmap`.  Other modules support networking protocols | 
 | that two or more processes can use to communicate across machines. | 
 |  |
