Used to provide reliable transport 1) alternating bit protocol (abp) and retransmission timers are of segments. the figure below shows a time sequence diagram of abp and retransmission a b data. req(a) d(0,a) data. ind(a) c(oko) data. req(b) d(1, b) retransmission timer d(1,b) data. ind(b) c(ok1) duplicate detected c(ok1) data. req(c) d(0, c) retransmission timer d(o, c) data. ind(e) timers being implemented. explain how retransmission timers and the alternating bit protocol work. considera link connecting two host at 10 mbits/secwith a propagation delay between each host of 250ms. if the hosts send 1000 bit segments, what is the maximum a. b. throughput, if alternating bit protocol is being implemented? why is this bad?

Write a pseudocode solution for each of these problems. 1. design a while loop that lets that user enter a number. the number should be multiplied by 10, and the result stored in a variable named product. the loop should iterate as long as product contains a value less than 100. 2. design a do-while loop that asks the user to enter two numbers. the numbers should be added and the sum displayed. the loop should ask the user whether he or she wishes to perform the operation again. if so, the loop should repeat; otherwise it should terminate. 3. design a for loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 100. 4. design a nested loop that displays 10 rows of # characters. there should be 15 # characters in each row. 5. convert this for loop to a while loop. declare integer count for count = 1 to 50 display count end for 6. find the error in the following pseudocode. declare boolean finished = false declare integer value, cube while not finished display “enter a value to be cubed.” input value; set cube = value ^ 3 display value, “ cubed is “, cube end while

Janice recently received her college degree and is looking for a job. she is worried that since she just finished school, she will be required to repay her perkins and direct subsidized loans immediately. janice pulls out the paperwork she signed and reviews it again for repayment information. after reading all of the information, janice discovers that

The ieee 802.11: defines standards for wireless local area network (wlan) communication protocols. identifies various computers or devices connected to a network. verifies any resource attached to another computer on a network that is different from the computer to which the user is logged on. connects multiple local area networks (lans) and wide area networks (wans).
