14. Network latency is the sum of four delays: propagation time,
transmission time, queuing time, and processing delay. Identify
where each of these delays occur and explain what causes the delay
for a datagram sent between two hosts over an Ethernet network.

Consider a 10Mbps Ethernet network consisting of 20 nodes
interconnected by a bus topology with a single bridge placed in the
approximate centre of the network resulting in an equal number of
nodes on each side of the bridge.
a) Briefly explain why collisions can/cannot occur.
b) If two pairs of nodes attempted to communicate at the same
time, discuss the throughput they can achieve.
when we consider the idea of genetic change in population over
time, what are the four general mechanisms of genetic change (along
with a brief description of each).
. Consider the scenario shown below, with four different servers
connected to four different clients over four three-hop paths. The
four pairs share a common middle hop with a transmission capacity
of R = 200 Mbps. The four links from the servers to the shared link
have a transmission capacity of RS = 70 Mbps. Each of the four
links from the shared middle link to a client has a transmission
capacity of RC = 30 Mbps per second.

What are some of the causes of the change in crime rates over the
last several decades? What are the current public perceptions about
crime in the Untied States? How do they differ from reality? Why do
people in the United States tend to have a high fear of crime? Why
do the southern United States have a higher homicide rate than
other regions of the United States?
