title: TCP - difference between Congestion window and Receive window
body: <p>I try to understand the difference between Congestion window and Receive window.</p>
  
  <p>As I understand, the receiver window is a buffer where the receiver can get the packets. The same is with the Congestion window which tell us the bound of the Receiver's abilities, and change according to lost packets, etc.</p>
  
  <p>So what is the diffrence between them?</p>
