TCP provides reliable transfer through a mixture of the sequence number, receiver buffer, cumulative acknowledgment, and fast retransmission. Answer the following True or False problems. If it's False, explain why.
a. Host A is sending host B a large file over a TCP connection. Assume host B has no data to send to A. Host B will not send acknowledgments to host A because host B cannot piggyback the acknowledgment on data.
b. The size of the TCP advertised window (RcvWindow) never changes throughout the duration of the connection.
c. Suppose host A is sending host B a large file over a TCP connection. The number of unacknowledged bytes that A sends cannot exceed the size of the receiver's buffer
d. Suppose host A is sending host B a large file over a TCP connection. If the sequence number for a segment of this connection is m, then the sequence number for the subsequent segment will necessarily be m+1.
