Week One
Assignment Question:
A ping message can be used to test the reachability of a host (such as Google with
IP address 8.8.8.8) on an Internet Protocol (IP) network.
List the steps a ping message takes to get to a host and what layer of the network
communication process each step relates to.
Your answer:
the operations of the internet ping program is much like a sonar echo-location,
sending a small packet of data comprising an ICMP ECHO-REQUEST to a particular
computer that then sends an ECHO-REPLY in return.
Your question:
How was PING invented?
Your sample answer:
Initially ping meant packet internet Groper which was a package for diagnostic
utilities utilised by DARPA.
Week Two
Assignment Question:
NQ-Real Estate has 8 workstations in a wired LAN with a 100 Mbps switch. It was
suggested to the admin officer to replace the switch with a wireless Access Point
(AP) that uses the 802.11ac standard and operates at 1 Gbps. Assuming all
workstations were simultaneously using the LAN, would the AP deliver faster or
slower speeds to the users? Explain your reasoning by including estimates of
effective bandwidth for each case.
Your answer:
AP will deliver slower speeds since it utilises RF which is not shielded form external
signals whereas cable are insulated with a sheath. Autonomously operating radios in
the same area yet utilising the similar or the same RF could interfere with each other
lowering the speed.

Week Three
Assignment Question:
Describe the difference between a network’s physical topology and its logical
topology and explain the advantages and disadvantages of a physical star topology.
Your answer:
Network’s physical topology alludes to the interconnected configuration of a LAN
(local area network).
Advantages
a) Cheap to implement
b) Easy to implement, handle and set up
c) Functions best for small networks
Disadvantages
a) Challenging to isolate errors on the network nodes
b) Not suitable for networks with high traffic as it increases load thus reducing
network efficiency.
c) Insecure since each device sees all data being transmitted
While logical topology involves structuring of the devices on a computer network and
the way they communicate with each other. In other words they define the way the
signal behaves on the network.
Advantages
Able to identify faults in the network since it determine how nodes communicate
Needs expertise to implement
Secure since not every device sees information transmitted
Disadvantages
Costly to implement
Hard to setup, implement and handle
Your question:
What is network topology?

Week Six
Assignment Question:
Internet Protocol version 6 (IPv6), the most recent version of the Internet Protocol
(IP), is the communications protocol that provides an identification and location
system for computers on networks and routes traffic across the Internet. As of 31
December 2017, the percentage of users reaching Google services with IPv6
reached 22.6% for the first time in regular measurements, growing at about 5.8% per
year, although varying widely by region. As of December 2017, about 33% of Alexa
Top 500 web servers support IPv6.
Explain how it is that IPv4 and IPv6 can co-exist (dual-stack IP implementation) in the
same network and describe two technologies that enable this.
Your answer:
In dual stack- IP implementation router, computers, switches and other devices
execute both protocols but IPV6 is the ideal protocol. This coexistence is enable by
two technologies NAT-PT (Network Address Translation-Protocol Translation) and
IPv4 NAT.
Your question:
What is the difference between IPV6 and IPv4 addresses
Your sample answer:
IPv4 is contains binary numbers that can be stored as text readable by humans and
such as 192.168.4.34 while IPv6 comprises 128-bit IP address separated by colours

Cloud computing is an information technology (IT) paradigm that enables ubiquitous
access to shared pools of configurable system resources and higher-level services
that can be rapidly provisioned with minimal management effort, often over the
Internet. Cloud computing relies on sharing of resources to achieve coherence and
economies of scale, similar to a public utility.
Cloud-computing providers offer their "services" according to different models.
Explain the three basic service models including one example for each.
Your answer:
 IaaS (Infrastructure-as-a-service) – with this model one can rent IT
infrastructure such as virtual machines, storage, operating systems, networks
and servers from a cloud provider on the basis of pay as you go. Such as
Cisco Metapod
 PaaS (Platform as a service) – this alludes to cloud computing services that
offer an on demand condition for testing delivering, developing and managing
softwares. PaaS is intended to make it easier for developers of mobile apps or
create web without being concerned about managing or setting up underlying
infrastructure of storage, network, database and servers required for
development. For instance Google App Engine
 SaaS (Software as a service) – it is a technique for delivering software over
the internet on demand and normally on subscription. For example Windows
Azure
