What are http connections types? What is the main differences between them? (10 points) Consider the pipelined reliable data transfer (rdt) protocols discussed in class over the channel that can corrupt or lose packets. (12 points or 4 each) I. What is the benefit of the sequence numbers for these protocols? II. What is the benefits of the introduced timers in these protocols? III. What is the benefits of the introduced sliding window in these protocols? 1. The figure below shows how data from a ROM can be transferred to an external register. The ROM has the following timing parameters: tACC = 250 ns and toE = 120 ns. Assume that the new address inputs have been applied to the ROM 70 ns before the occurrence of the TRASFER pulse. Determine the minimum duration of the TRANSFER pulse for reliable transfer of data. Ao Transfer CS U Dy De Ds DA ROM 256 x 8 Da D D Do D7 De Ds DA 8-bil Da register D D Do 74ALS273 CLK Q7 dddddddd
