Host A wants to send a large file to Host B. The path has 10 links each with a rate of 1 Mbps. If the file size is 10Mb, how long will it take for the file transfer:

a. If the complete file is assembled at the end of each link before transmitting it to the next?

b. If there is no assembly at the end of each link before transmitting?

c. If the file is divided into packets of size 10 Kb and each packet is assembled at a link completely before further transmission?
