  18. Which of the following describes the operation of TCP window size? • Window size increases as all data transfers. • Window size is the TCP process used prepare data for transmission. • Window size is decreased if packets are lost. • Window size of 15 means that the next byte expected is byte number 15. • Window size increases as all data transfers. • Window size is the TCP process used prepare data for transmission. • Window size is decreased if packets are lost. • Window size of 15 means that the next byte expected is byte number 15.
