title: What is the argument of connectionSocket.recv?
body: <p>In <code>connectionSocket.recv(1024)</code>, does <code>1024</code> mean the buffer size of the server in Python or does it mean the buffer size of the socket?</p>
  
  <p>I have just started to learn Python so I am a beginner. However, I am the kind of person who cannot move forward without knowing the actual meaning.</p>
