Suppose two hosts, a and b, are separated by 7,500 kilometers and are connected by a direct link of r = 10 mbps. suppose the propagation speed over the link is 2.5 x 10 8 meters/sec. consider sending a large packet of 500,000 bits from host a to host b. how many milliseconds (ms) does it take before the receiver has received the entire 500,000-bit file?

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)
