Answer 1

TCP uses a congestion window in the sender side to do congestion avoidance. The congestion window indicates the maximum amount of data that can be sent out on a connection without being acknowledged. TCP detects congestion when it fails to receive an acknowledgement for a packet within the estimated timeout.

Answer 2

congestion reduces avoidence of packet losses control the network capacity and reciver window size

Answer 3

Suppose Reciever Window size is 1GB  and maximum segment size is 1MB so the sender can send maximum of 1024 packet at a time but the problem what is the capacity of network . Let us say that window size of network is 500MB and maximum segment size is 1MB so it will allow only 500 packet at max. So, here we use the concept of Congestion Control
