Assignment Question: Counting with different number systems:
You may know what a number system is: a number system is a way to represent numbers. For example, we are using the base-10 number system, which is called
decimal. Other common number systems include base-2 (binary). base-16, base-8 (octal), and (hexadecimal). In computer science, information is often stored as base-
2 (binary) but presented as base-10 (decimal) or base-16 (hexadecimal). For example, IPv4 addresses (and/or IPv6 addresses), MAC (hardware) addresses (see
the diagram below) are usually presented in decimal or hex, but internally computers store them in binary.

•  View the IPv4 address and MAC address (Physical Address) of your computer. Then convert both addresses to binary, showing the calculations for each conversion. In your answer also include one or more screenshots showing the addresses on your computer.

Assignment Question:
The ping command is used to test the reachability of a specified destination computer. The ping command operates by sending several (Internet Control Message Protocol) messages to a destination computer and waiting for a response (the messages are referred to as Echo Request and Echo Reply). The output of a
ping command contain two major pieces of information: how many of those responses are returned, and how long it takes for them to return. The ping command
is one of the most often used networking utilities for troubleshooting network problems. Complete the following questions:

•  Assume you want to test the reachability to the Google searching service, create a ping command with 10 ICMP echo requests, with each echo request packet size set to 512 bits. Include a single screenshot that shows both the ping command and its output as your answer.
•  Explain the difference between “ping www.google.com” and “ping the IP address of Google server at 172.217.167.68”. You may want to try both and observe any differences. Your answer should include your explanation; it doesn’t need to include screenshots.

Assignment Question:
Describe is the difference between operating in half-duplex mode or full-duplex mode. Explain why switches can eliminate collisions in LANs, whereas hubs cannot.

Assignment Question:
Draw a network diagram with the following requirements:

•  A wired Local Area Network (LAN) with 5 workstations, organized as a star topology
•  A wireless LAN with an Access Point (AP) and some laptops and mobile phones.
•  A router to link these two LANs to an Internet Service Provider (ISP)

Assignment Question:
ABC Corp.’s facilities in Hermit Park, Townsville, are two office buildings 150 metres apart, each with its own LAN. To connect the two networks, you plan to dig a trench
and lay cable in conduit between the two buildings. You want to use fibre-optic cable, but your budget-conscious facilities manager wants to use 100 Mbps Ethernet over
twisted-pair cable. Which of the following reasons can you use to justify fibre-optic cable in this case, and why?

•  Twisted pair won’t span a 150-metre distance.
•  Fiber-optic cable is cheaper and easier to work with than twisted pair.
•  Twisted pair is a conductive cable and can, therefore, carry current based on the difference in ground potential between the two buildings.
•  Fibre-optic cable leaves more room for growth and future needs for increased bandwidth than twisted pair does.

Assignment Question:
When you try to ping a server on your local network, your operating system needs to convert the IP address into a MAC address. Answer the following questions:
1) To resolve a local IP address to a physical MAC address, which protocol can be used? Which layer of the TCP/IP layered architecture does the protocol
belong to?

2) Briefly discuss how this protocol works, including how the protocol avoids sending a request across a network for each IP packet that needs to be sent
to the same destination.

Assignment Question:
A network diagram shows the connection of four computers and the network devices: a repeater, two switches and a router. The port numbers (P1, P2, and P3) in the
diagram refers to the ports on the respective switches. The MAC addresses of the computers and the router (where indicated by the arrow) are given in the diagram.

If the four computers have been actively communicating with each other, what would the entries of the switching table be for Switch S2? Fill in the switching table below
with the relevant entries. Any order of entries is acceptable.

Assignment Question:
You have an idea for a cloud-based IoT application that can monitor your living/working/studying environments by collecting and demonstrating the data of
temperature, humanity, air quality and so on. You need a development server for your team members (classmates across several campuses). And then, once the
software is developed and deployed with required hardware, you need a hosting solution for users to access to the software and users can check their living/working/studying environments on their tablets and smartphones.

 What types of cloud computing service are appropriate to these situations? Justify your answers.
