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.

What is the total delay (latency) for a frame of size 5 million
bits that is being sent on a link with 10 routers each having a
queuing time of 2 μs and a processing time of 1 μs. The length of
the link is 2000 km, The speed of light inside the link is 2 x 108
m/s, the link has a bandwidth of 5 Mbps. Which component of the
total delay is dominant? Which one is negligible? useAPA...
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.
