General Information
The purpose of this assignment is to respond to a series of short-answer questions relating to content in weeks XXXXXXXXXXYou are also required to develop ten of your own short-answer questions and sample answers, one for each week XXXXXXXXXX).
The assignment is marked out of 30 and forms 30% of your total unit marks.
Note that late penalties apply (5% of the total available marks per calendar day late or part thereof).  Assignments received 14 days or more after the due date will not be marked and will receive zero. For special circumstances, students may apply for extension on due date. Documentary evidence must be provided to support the request (for example, a medical certificate). Use the link to 'Assessment Extension Request' at the left hand side of this unit web page to apply. It is better to manage your tasks and time so that you can submit the assignment on time. Delay in completion may have impacts on your studies and preparation for exam.
While it should not be necessary to use literature/online resources to complete this assignment, please ensure you cite and reference any such materials using the Harvard format.  Plagiarism detection will be used in this assessment.
It is VERY important that you do not copy content directly from either the text or Internet resources:  this assignment is to be in your own words.  You will lose marks if you do not use your own words!  Actual plagiarism will result in the instigation of the student misconduct process.
What do I need to do?
First, download the template.  Edit this file as you complete your assignment, entering in your responses to the weekly questions and adding your own questions and sample answers in the relevant sections.  Remember to save your work regularly.  When you have finished you assignment, upload the completed template as your assignment submission.
The assignment is
oken into weekly sections, each section consisting of two tasks.  Your first task is to answer the assignment questions - there is one for each week.  The answers to the questions can be found in the text, but you must respond in your own words.  Each response is marked out of 1.5 marks:  the marking criteria are in the template.
Your second task for each week is to develop your own short-answer question and sample answer.  This question should be relevant to the topics covered for the particular week, so for example, in week one, you could develop a question relating to anything from hardware components, basic network communication/terminology through to network models which can be found in chapter one. Try to base the question on an area of content that you found challenging.  Imagine if you were writing an exam for the unit: what questions would you ask?  Use your imagination and make sure you use your own words for both the question and the sample answer.  Each question/sample answer is marked out of 1.5 marks:  the marking criteria are in the template.
The assignment is marked out of 30 and forms 30% of your total unit marks.
Hints
Hint 1: Example Sample Question/Answer (Detail)
The following is an example of the type of question you might develop and the level of detail required in the sample answer.  Note the level of detail in the answer is similar to that expected of you in most weekly assignment question responses.
Question: What is the difference between an incremental and a differential backup?
Answer: An incremental backup will copy all files changed since the last full or incremental backup and mark these files as backed up. A differential backup will copy all files changed since the last full backup; but won't mark the files as being backed up.  When restoring an incremental backup, each backup since the last full backup must be restored in sequential order, ending at the latest incremental backup. With a differential backup, however, only the last full backup and the last successful differential backup need to be restored.
Hint 2:  Do a bit every week
This assignment is not onerous, especially if you complete each weekly section as you complete each week of the unit.  However, it will be much harder if you try to complete all the sections in week eleven!
Hint 3:  Ask!
If something in this assignment description is unclear, or you are just not 100% sure about something, please ask for help.  Your teaching team really do not mind if you ask us to clarify something.  We do mind when we have to fail you because you haven't submitted what was asked or met the assignment requirements

“Sebastian’s Sea Creatures” is a family fun park that exhibits rare and weird animals from the ocean depths. Employees log onto their computers with usernames and passwords that are managed by a domain controller. What type of network model is being used at Sebastian’s Sea Creatures? Describe one (1) advantage and one (1) disadvantage of this model.
Your answer:
The network model is used to represent the objects with their related responsibilities in a flexible manner. The Sebastian’s Sea Creatures is using protocol based model for their work. The point to show advantage of prototype model for Sebastian’s Sea Creatures is as given below:
1. This model uses a hierarchical structure for user authentication. The employees of Sebastian’s Sea Creatures can only access the data as per their level of authorization.
2. The security of database for Sebastian’s Sea Creatures can be improved.
The point to show disadvantage of prototype model for Sebastian’s Sea Creatures is as given below:
1. The processing of data overhead is main disadvantage of this model.
Your question: What are the various network models which are mostly used in organization?
Your sample answer:
A network is considered as the backbone of any organization. The organization uses various network models as per their requirements. The representation of objects with their related responsibilities in a flexible manner is considered as a network model. The basic types of network model are: Reference model and protocol model.
Both of these models can be deployed as per the requirement of user.

Week Two
Assignment Question:
Sebastian’s Sea Creatures has 25 workstations in their administration office. You are the IT manager for the company and Sebastian has asked you to replace the 300Mbps wireless access point (AP) that services the office with a 100Mbps switch. Will this increase or decrease the bandwidth available to each workstation? Explain your reasoning by including estimates of effective bandwidth for each case.
Your answer:
The replacement of 300Mbps wireless access point with 100Mbps switch will decrease the available bandwidth. The possible reasons for it are listed below:
1. The replacement of wireless access point with 100Mbps will increase the traffic overhead.
2. In case of low bandwidth, slow internet will be caused.
The following methods can be used to increase the bandwidth of network:
1. Ethernet can be deployed in place of Wi-Fi.
2. IN case of DSL, the network filters can be checked.
Your question:
What is network analyser and what is its role to identify network bandwidth.
Your sample answer:
A hardware or software program which is used to check the bandwidth, unauthorized activities in any specific network is known as network analyser. The most common example of network analyser are, NAST, Wireshark, Angry IP Scanner and Zenmap. These are used to monitor the effects on bandwidth for changing the device like router and switch.
The network analyser can monitor the bandwidth to help the network administrator. This tool is very helpful for effective management of network.
Week Three
Assignment Question:
There are two other LANs at Sebastian’s Sea Creatures, one for the café (called CAFE) and one for the admissions gate (called GATE). There are 5 workstations on each LAN. On CAFE, the workstations connect to a 100Mbps hub. On GATE, the workstations connect to a 100Mbs switch with all ports operating in half-duplex mode. If you connected your laptop to GATE, would it be subject to more, the same or less collisions than if it was connected to CAFE? You can assume data rates and traffic patterns are the same on each LAN. Justify your answer by explaining the origin of the collisions.
Your answer:
As it is given that Sebastian’s Sea Creatures is using two different LAN named as CAFE and GATE. Each of the LAN is having only five computers. When user tries to make connection of his/her laptop on GATE LAN, then, there is chance of more collision. It is possible that the user wants to acquire the same resources which are already occupied by any other computer of same LAN. The traffic pattern of GATE LAN and data rate are also responsible to measure the LAN capabilities.
The collision occurs when the two different processes uses same route to transfer their data and want to acquire the same resources at same time.
Your question:
What do you meant by collision and how it can affect the network capabilities?
