You download a file of size 180 Gbyte in one hour. What is the average goodput (the useful throughput measured at the application layer) in Mbit/s? Assume that the data is transfered as a sequence of data packets, each consisting of 200 Byte of useful data plus overhead. How long is the time interval between each packet in microseconds? Assume that the overhead is 40 Byte per packet (header, trailer, interpacket gap). What is the net bir rate or total throughput (at a reference point between the physical layer and data link layer)? Assume that the data is transferred using a 4B5B bit synchronization and error detection code (4 net bits transferred using 5 bits). what is the physical layer gross bit rate? Assume that the data is transferred using 16PAM (16-level pulse amplitude modulation). How many bits are transferred per pulse?What is the pulse rate? What is the required baseband bandwidth in Hertz according to Nyquist?
