General Assessment Information

Assignments

Assignment work must be written clearly, with good grammar, correct word usage, correct punctuation,and lack of spelling errors. Poor or bad expression will be penalized, Wherever required, all written work must be properly referenced and conform to standard stylistic conventions.

Practicals

Note that while the practical material is structured against the lecture material, you need to keep in mind that there will not always be a one to one mapping between the practical exercises and the lecture topics. This is because you need some practical sessions to get acquainted to new tools and devices thereby limiting the number of practical time slots available to experiment with technologies discussed in some lectures.

Practical work

Due: Every week
Weighting: 10%
This is a hurdle assessment task (see assessment policy for more information on hurdle assessment tasks)

The practical work in this unit makes up 10% of your mark. The practical work is divided up into ten sections. You are expected to complete all ten. Practical classes are a hurdle requirement, and, as such you will be required to perform to a satisfactory standard in at least six of the practical classes to pass the unit. Each practical contributes 1% of your total mark for the unit.

To receive your marks you must attend the practical section and demonstrate your completion of the section to your practical supervisor. Earning the marks will require not only successful completion of the exercises, but presentation of appropriate documentation, as outlined in the question sheets. You must complete the practical session in the week it is allocated.

Practical classess will commence during week 2 of the semester. Students must be enrolled in two practical classes: Practical_1 and Practical_2.

Practical_1 will utilise specialised networking equipment located in an Engineering Laboratory whereas Practical_2 will be conducted in a regular Computing Laboratory.

Tutorial Submissions

Due: Weekly
Weighting: 10%

Each week tutorial problems will be posted in iLearn related to the lecture content for that week. 

By the end of each week you are required to submit your responses in the manner specified in the questions for that week. Your answers will need to demonstrate appropriate depth of understanding.

All submission are done via turnitin.

General notes on tutorial submissions:

The tutorial submissions are important for your learning.   We set a number of questions that you should think carefully about. Don't be late with submission -- iLearn is an automated system with a strict cutoff time. Always try your hardest with these questions -- you only get the learning benefit if you think carefully. But don't worry if you're not completely sure about your answer.  The important thing is to have a go and submit the best answer you have.

We'll try to ensure that the tutorial questions don't involve too much writing.   So you should expect that you can answer them in half a page or so.

The tutorial submissions are essential, but will only be "sample" marked in detail (a small sample of student submissions will be fully marked). General feedback about the questions will be given in lectures, and if you'd like individual feedback or if you'd like to discuss a question in more detail you should raise it with your practical teacher.  The questions are meant to help your learning, so we will usually award you the full marks available if you have completed a reasonable attempt at the specified questions.


On successful completion you will be able to:
  • Enunciate the importance and the role of network protocols including why they are organised into protocol stacks and how protocol stacks function.
  • Demonstrate an understanding of IP addressing, routing and subnetting by for example computing routing outcomes and determining effective and actual IP addresses.
  • Differentiate among LAN components, and describe and, in particular instances calculate, how MAC addresses, address resolution (as implemented by protocols such as ARP) and the ethernet protocol interact.
  • Be aware of different major network technologies including wireless, backbone, wide area networks, and the Internet and, being aware of their properties, be able to evaluate different network designs.

Final Examination

Due: End of semester exam period
Weighting: 50%
This is a hurdle assessment task (see assessment policy for more information on hurdle assessment tasks)

The final examination allows us to individually and securely assess each student's mastery of the coursework material.  The examination will be closed book and three (3) hours in length.

Regarding the examination process, note that

  • you must be available to attend the examination at the time set by the University which may be any time during the official University Examination period for First Half Year
  • you are expected to present yourself for examination at the time and place designated in the University Examination Timetable
  • no early examinations for individuals or groups of students will be set. All students are expected to ensure that they are available until the end of the teaching semester, that is until the final day of the official examination period
  • if illness or unavoidable disruption prevents you from sitting the examination at the designated time, you should contact the University in accordance with the Disruption to Studies policy. You will need to provide documentary evidence of the circumstances.

Supplementary Exams

If you receive special consideration for the final exam, a supplementary exam will be scheduled in the interval between the regular exam period and the start of the next session.  By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments.  Please ensure you are familiar with the policy prior to submitting an application. You can check the supplementary exam information page on FSE101 in iLearn (bit.ly/FSESupp) for dates, and approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.

If you are given a second opportunity to sit the final examination as a result of failing to meet the minimum mark required, you will be offered that chance during the same supplementary examination period and will be notified of the exact day and time after the publication of final results for the unit.


On successful completion you will be able to:

Changes from Previous Offering

During previous offerings all practical classes were completed in a specialist networking laboratory.   This year we have reconstructed the practical work to include new material that also uses resources available in standard laboratories, and students will from week to week alternate between the normal computing laboratories and the specialist networking lab.  Many modern networking tools are now designed to run on standard computing equipment.

Last year the unit was run, unusually, with no hurdle assessments.  This year the hurdles have been reinstated.

Grading

Grading

At the end of the semester, you will receive a grade that reflects your achievement in the unit

  • Fail (F): does not provide evidence of attainment of all learning outcomes. There is missing or partial or superficial or faulty understanding and application of the fundamental concepts in the field of study; and incomplete, confusing or lacking communication of ideas in ways that give little attention to the conventions of the discipline.
  • Pass (P): provides sufficient evidence of the achievement of learning outcomes. There is demonstration of understanding and application of fundamental concepts of the field of study; and communication of information and ideas adequately in terms of the conventions of the discipline. The learning attainment is considered satisfactory or adequate or competent or capable in relation to the specified outcomes.
  • Credit (Cr): provides evidence of learning that goes beyond replication of content knowledge or skills relevant to the learning outcomes. There is demonstration of substantial understanding of fundamental concepts in the field of study and the ability to apply these concepts in a variety of contexts; plus communication of ideas fluently and clearly in terms of the conventions of the discipline.
  • Distinction (D): provides evidence of integration and evaluation of critical ideas, principles and theories, distinctive insight and ability in applying relevant skills and concepts in relation to learning outcomes. There is demonstration of frequent originality in defining and analysing issues or problems and providing solutions; and the use of means of communication appropriate to the discipline and the audience.
  • High Distinction (HD): provides consistent evidence of deep and critical understanding in relation to the learning outcomes. There is substantial originality and insight in identifying, generating and communicating competing arguments, perspectives or problem solving approaches; critical evaluation of problems, their solutions and their implications; creativity in application.

In this unit, the final mark will be calculated by combining the marks for all assessment tasks according to the percentage weightings shown in the assessment summary. The final examination in this unit is a hurdle requirement; you must get a mark of at least 40% in the examination to pass the unit. If you get a mark between 30% and 40% in your first attempt at the final examination, you will be given a second and final attempt. The practical classes are also a hurdle assessment, you will be required to perform to a satisfactory standard in at least six of the practical classes to pass the unit.

Concretely, in order to pass the unit, you must obtain an overall total mark of 50% or higher, a mark of 40% or higher in the final examination, and satisfactorily complete at least 6 out of the 10 practical exercises.

Students obtaining a higher grade than a pass in this unit will (in addition to the above)         

    • have a total mark of 85% or higher to obtain High Distinction;
    • have a total mark of 75% or higher to obtain Distinction;
    • have a total mark of 65% or higher  to obtain Credit.
