1. Compare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 4 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel) by the receiving host (Host B) and the sending host (Host A) respectively. Suppose Host A sends 4 data segments to Host B, and the 3rd segment (sent from A) is lost. In the end, all 4 data segments have been correctly received by Host B. Suppose each data segment has only byte data and 4 data segments have sequence numbers 1, 2, 3, 4. 1) For all three protocols GBN, SR and TCP, how many segments has Host A sent in total and how many ACKs has Host B sent in total

If you go to ask a question and say ask, there should be something that looks like this

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !

Don’t know sorry if i know it later i would put it here
