Suppose two hosts, a and b, are separated by 20,000 kilometers and are connected by a direct link of r = 2 mbps. suppose the propagation speed over the link is 2.5*108 meters/sec. a. calculate the bandwidth-delay product, r*dprop. b. consider sending a file of 800,000 bits from host a to host b. suppose the file is sent continuously as one large message. what is the maximum number of bits that will be in the link at any given time? c. provide an interpretation of the bandwidth-delay product. d. what is the width (in meters) of a bit in the link? is it longer than a football field? e. derive a general expression for the width of a bit in terms of the propagation speed s, the transmission rate r, and the length of the link m.

Write a function called checkfactor that takes two arrays of positive numbers, firstnumberrow and secondnumberrow. checkfactor checks if the first entry in firstnumberrow is divisible by the first entry in secondnumberrow, and performs the same operation on the next array elements until all entries have been checked. all the numbers are positive and the number of entries in the arrays are the same. the function should return the identified divisible numbers in two row arrays named firstdivisible and seconddivisible.restrictions: branches or loops should not be used. the code must use the internal mod and logical functions.hint: the mod function should be used to determine if two numbers are divisible. ex: for num1 and num2 if mod(num1,num2) is 0, then the two numbers are divisible.this is matlab

Suppose you are an ad-serving company and you maintain a log of cookie data for ads you serve to the web pages for a particular vendor (say amazon). a. how can you use this data to determine which are the best ads? b. how can you use this data to determine which are the best ad formats? c. how could you records of past ads and ad clicks to determine which ads to send to a given ip address? d. how could you use this data to determine how well the technique you used in your answer to part c was working? e. how could you use this data to determine that a given ip address is used by more than one person? f. how does having this data give you a competitive advantage vis-à-vis other ad-serving companies?
