Computer Networks question help:

True/False questions and a reason (if applicable) as to why it is true or flase:

1. The TCP receiver sends an acknowledgment of sequence number n if it has correctly received byte n. T/F

2. The main motivation of TCP flow control at the sender is to avoid network congestion. T/F

3. When losses are present, Selective Repeat schemes are more efficient than Go-Back-N schemes. T/F

4. Congestion control can be implemented on an end-to-end basis or with network assistance. T/F

5. Host A is sending host B data over a TCP connection, but host B has no data to send to host A. Host B will not send TCP acks to host A because host B has no data to piggyback the acks on. T/F
