Question
In a CSMA/CD network, the end hosts are upgraded
from 10Mb/s to 100Mb/s. The size and layout of the physical
network otherwise remains the same. Which of the following
are true?

larger.
B. The network will continue to work without change
because the packets will arrive ten times sooner.
C. The first bit of each packet reaches the destination 10
times sooner.
D. The amount of time a packet spends on the wire is
decreased by 10 times.
