Module Aims

This module aims to provide an understanding of the technology underlying network operation fornetwork types ranging from small, local -area networks to the Internet with its global coverage. Thisestablishes the technical background needed to appreciate the capabilities of computer net works, tomanage networks, and to evaluate networks intended to meet specific enterprise requirements.Having established how networks are capable of providing connectivity can be established on anyscale, the module then proceeds to cover the linking of s uch networks and their management as wellas some security concerns.

This readily accessible and managed fabric has the capability to support many applications, and, whatis more, to support different applications at the same time. The reasons for this ve rsatility andflexibility are considered, and the ways in which they may be realized are examined. It is shown thatthe applications can be grouped under the broad headings of communication, digital libraries, and themarket place. The specific examples co nsidered under the respective heading include electronic mailand Electronic Data Interchange, the World -Wide Web, and various aspects of electronic commerceand Internet commerce.

Formal Reports - A recursive View

Abstract

Research or development is effectively useless if it is not communicated to other people.Many mediums for this communication exist, e.g. books, scientific papers, reports, televisionand lectures. Each medium is appropriate to the material it is to be used to impart. A formalreport is often used to communicate laboratory work. To ensure that such reports achievetheir aim, it is necessary to adopt a common format for that report. This document describesa common format and explains some ramifications and thoughts that lie behind the choice ofthat format.

Introduction

The results of laboratory work are always important. Even if an experiment failed it is stillnecessary to report and share results , not merely to record them. If results are not

communicated, or the communication is itself a failure, then appropriate conclusions orcourses of action cannot be taken; the work then becomes effectively insignificant. It istherefore important that scientific work be imparted in a proper manner. Many mediums exitfor the proper and successful communication. A formal report is that medium chosen for t heproper communication of laboratory work.

TheoryOverview

Communication of scientific work often takes a similar format, whatever the chosen mediumis. This format can be summarise d as:

y summary or abstract;

y introduction;

y theory;

y procedure;

y results;

y discussion and further work;

y conclusions;

y references and appendicesIt is advised that a formal report follows closely this format.

Summary or Abstract

The abstract should be a brief summary of the contents of the report. This is the part which ismostly used to understand the subject area and the nature of the report and great careshould be taken when it is written.

Introduction

The introduction should briefly place work in its appropriate context and gently lead in to thesubject of the report. It should describe other, closely related, work in the field - using

reference where necessary - hence placing the work in its historical and technical context.

TheoryThe major theory required by a reader to understand the work should be described. It maysometimes be necessary to omit this section or place its content in appendices.

Procedure

A description of the experimental procedure should cover techniques, equipment andcomponents used, and their limitations (where appropriate).

8/6/2019 4810-ModuleHandbook2010-20110 (1)

12/20

12

Results

Results should be presented, highlighting important features, so as to draw the readersattention to the success of the work. Much use should be made of graphs, waveforms andtables, if applicable.The results of a scientific work are always difficult to assess. In prepa ringfor this, you as the author should ask yourself does it achieve its objectives? Is it a clearreport? Have there been any mistakes? etc

Discussion (and further work)The results of the work should be discussed and explained, compared with theory to validateresults. It is sometimes impossible to distinguish between results and their perusal, and itmay be advantageous to combine these sections.

Conclusions

The conclusions should briefly underline major results and their relevance and importance.

References and Appendices

Any references cited should be placed in a list after the conclusion. Appendices shouldcontain material not directly relevant to the main body of the report, i.e. specifications of

components.

Note: The above structure obviously will not suit all reports. Sometimes it may be necessaryto omit some sections, sometimes to include others. The sections you should never omit arethe abstract, the introduction, the discussion and the conclusions.

Paper format: Please visit the link

http://www.ieee.org/publications_standards/publications/authors/authors_journals.html forguidelines on how to write a journal paper. This format is the IEEE one.It will also be providedin oasis.

Poster and individual presentationassignment

Learning outcome:

y To present the knowledge gained with a journal.

Each student should summarise his/her Journal in a Poster and give a presentation of 5minutes about it. Journals, posters and individual presentations together count as 15% of thetotal marks.

Labs and seminarsGuidelines for group formation and sheets for working through seminars/lab are presentedhere. You would be expected to carry out activities related to previous lectures in eachseminar session. YOU MUSTSHOWYOUR COMPLTETED WORK to YOURTUTOR ATTHE END OFEACHLAB SESSIONTO BE GRADED.

Group presentationassignment

In real life Engineers and computer scientists work in small groups (4 to 10 persons), whereindividual tasks are assigned to group members either by senior managers or group/project

8/6/2019 4810-ModuleHandbook2010-20110 (1)

13/20

leaders through decisions, ability and preferences. However, it is quite often that you findopposition from other groups who think otherwise. So it is rather important that you should beprepared to vigorously defend what you are presenting.

A group project will give students the experience of working with other colleagues who theymay or may not have something in common. The main objective of such an exercise is forthe group members to realise their own qualities and shortcomings and to show groupdynamic and professionalism. This type of presentations will help each individual memberrealise the following:

j The importance of feeling and being an active and a valued member of a group

j Being able to proportion and receive praise and blame

j Ability to identify important tasks and to have fruitful discussion with group members

j Ability to research a given topic and bring in important information to the group

j Ability to observe and assess group members and give positive/constructive feedback

j Ability to allocate responsibility through civilised discussions

j Ability to represent your group in the official presentation sessions

j Ability to assess other presenting groups in a constructive and balanced way

Seminar Sheet 1: Introduction and Group FormationOrganising the presentations

This component of the assessment carries 15% of the overall grade. The main objective isdeveloping group dynamics, team-work, interactive skills, debating and presentation skills.

Each group will present its findings for 25 minutes (the timing can be changed by the seminartutor according to the total number of students) .

Assessment criterion

Journals and posters

Your Journal paper will be marked on accept/Reject bases, if rejected, a maximum mark of40%will be awarded regardless of the quality of the paper or the poster presentation. Journalpaper and poster together contribute 15% of the module overall grade. More specifically, yourJournal paper contribute 50% and the poster will carry another 50%. Please see markingscheme below for detail.

Late submissions will be decremented by 5% for every day the paper is overdue to themaximum of 25% of the overall marks. Late submissions with valid extenuatingcircumstances must be notified to the students office prior to the deadline for submission ofcoursework.

Attendance Requirements

You should attend all scheduled classes. If you do not do so, you may not be able to demonstrate thatyou have achieved the Learning Outcomes for the module, and you are at risk of being graded X in themodule. The definition of the X grade is: Fail incomplete without good reason: may not be reassessed.

As a general guide, you need to attend at least 75% of scheduled classes oin order to be able todemonstrate achievement of all Learning Outcomes. On some modules, there may be more specificattendance requirements.

Academic Dishonesty

Taking unfair advantage in assessment is considered a serious offence by the university, which will takeaction against any student who contravenes the regulation through negligence, foolishness or deliberateintent.

Academic dishonesty is a corrosive force in the academic life of the university; it jeopardises the quality ofeducation and devalues the degrees and awards of the University.

The full regulations on academic dishonesty are given in the University Regulations, Section FInfringement of assessment regulations - academic misconduct.

Plagiarism

Plagiarism is one specific form of cheating.

The University Regulation Section F clearly sets out the Universitys understanding of plagiarism and theregulations by which you as a student of the University are bound. The key University regulation is F2.3which defines plagiarism asThe presentation by the student as their own work of a body of material(written, visual or oral) which is wholly or partially the work of another, either in concept or expression, orwhich is a direct copy.

Work presented for assessment must be the candidates own, or the work of a project group as requestedby the tutor. Plagiarism is the representation of another persons published or unpublished work as thecandidates own by unacknowledged quotation. It is not an offence if the material is acknowledged by thecandidate as the work of another through the accurate use of quotation marks and the provision of

detailed references and a full bibliography, although the Assessment Board will not expect work to relyheavily on direct quotations.

In addition, the University Regulations set out the process for investigating allegations of plagiarism anddescribes the penalties. If you are found guilty, the repercussions are very serious indeed.

You should take steps, therefore, to understand what plagiarism is, how it can be identified and how youcan avoid committing it; perhaps most importantly, you should reflect and come to understand why it is toyour enormous advantage never to plagiarise because it is in effect cheating yourself and your fellowstudents).
