False. The TCP RcvWindow (Receive Window) does change throughout the duration of the connection.
The Receive Window is a mechanism used by TCP to manage the flow of data between the sender and receiver. It represents the amount of data that the receiver is willing to accept and is communicated back to the sender. As data is received and processed by the receiver, the RcvWindow size decreases, indicating that the receiver can accept more data. Conversely, if the receiver's buffer becomes full or it cannot consume data fast enough, the RcvWindow size will decrease, indicating to the sender to slow down and not overwhelm the receiver.
Therefore, the RcvWindow size dynamically changes based on the receiver's capacity and ability to process incoming data, ensuring efficient data transfer over the TCP connection.
