Problem
Your company is transmitting 500-character (byte) records at a rate of 400,000 bits per second. You have been asked to determine the most efficient way to transmit these records. If a Stop-and-wait error-control system is used, how long will it take to transmit 1000 records? If a sliding window error control is used with a window size of 127, how long will it take to transmit 1000 records? If, on the average, one record in every 200 records is garbled, how long will it take to transmit 1000 records? What are your conclusions?
