I need help with C, D, and E.

A and B completed.

Round Trip Time(RTT) on a link between two hosts is 100 milliseconds and the bandwidth is 106 Bytes/second. Calculate total time taken to transfer a file of size 1000 Kbytes under the following conditions Assume that the link is reliable (no ack needed). How long does it take to transfer a file when sent as a message? The header size of the message is 100 bytes The file is broken into packets of size 1 Kbyte. Only 1 packet can be sent per RTT. Ignore packet header size in problems b-e The file is broken into packets of size 1 Kbyte. 20 packets can be sent per RTT The file is broken into packets of size 1 Kbyte. Bandwidth is infinite (zero transfer time) The file is broken into packets of size 1 Kbyte. Bandwidth is infinite (zero transfer time) and 20 packets can be sent per RTT a. b. c. d. e
