Question

Computer Networks 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

Answer 1

1) True.

Yes its true the tcp can send no of acknowledements depends on the no of requests it gets.

2) True.

The main theme of tcp protocol is to avoid network congestion.

3) True.

If the errors are present, then selective repeat schemes is the most efficient because if we use go back n process we need to do all the requests and responces but if we use selective repeative only error request can we change.

4)  .True.

its true because of tcp uses end to end network
