title: listen() method parameters in python
body: <p>I'm new to Python and interested in socket programming these days. From the youtube videos, I'm building a simple server but I didn't get <code>listen()</code> method very well. I know "it listens" incoming connections but I didn't get the the idea of "maximum queued connections" in the document. Could you explain this concept in layman's terms so that I can understand better?</p>
