<p>The modules described in this chapter provide mechanisms for different processes
to communicate.</p>
<p>Some modules only work for two processes that are on the same machine, e.g.
<a title="Set handlers for asynchronous events." class="reference external" href="signal.html#module-signal"><tt class="xref docutils literal"><span class="pre">signal</span></tt></a> and <a title="Subprocess management." class="reference external" href="subprocess.html#module-subprocess"><tt class="xref docutils literal"><span class="pre">subprocess</span></tt></a>. Other modules support networking protocols
that two or more processes can used to communicate across machines.</p>
<p>The list of modules described in this chapter is:</p>
