<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 class="reference internal" href="signal.html#module-signal" title="signal: Set handlers for asynchronous events."><tt class="xref py py-mod docutils literal"><span class="pre">signal</span></tt></a> and <a class="reference internal" href="subprocess.html#module-subprocess" title="subprocess: Subprocess management."><tt class="xref py py-mod 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>
