The processor is 2.5 GHz, bus clock is 500 MHz and a 5 Mbps modem

1) How long does it take to move 64-byte packet from its arrival at the modem until its receipt in the memory area of the target application program or service? State your answer in elapsed time (seconds or fractions s of seconds)

2) The computer is running a program thats downloading a large file by using the moderm, and all packets are 1024 bytes. What percentage of the computers CPU capacity is used to manage data transfer from the modem to the program? What percentage of available bus capacity is used to move incoming data from the modem to the program? Assume the bus uses a simple request/response protocol without command acknowledgement.
