CET101 Fundamentals of Computing 2013-14

Portfolio 3: Research & Presentation for “Natty Notebooks Inc.”

All of your portfolio work in CET101 is individual work.

In this portfolio, we are assessing the skills you have developed so far in the following areas:

• Fundamental knowledge of the theoretical underpinnings of computer science

• Appraisal of the fundamental operation of computer systems, network architectures, hardware components, operating systems and associated protocols and data structures

• Ability to specify and contextualise a problem and communicate effectively an appropriate solution to a range of audiences

Portfolio Task:

In the computing world today, networks, their associated devices and infrastructure are playing an ever more essential part in the applications writer's career. More and more software produced today now depends on being able to communicate data between different computer systems across networks, some of which span the globe.

The scenario: a firm “Natty Notebooks Inc.” is busily setting up its company network and World Wide Web provision (some applications for which you will be involved in a future portfolio item) so that staff can communicate effectively across departments and public access for sales. The company is based in Sunderland which is their headquarters with a call-centre in Middlesbrough, a warehouse and distribution centre in Newcastle, and two high-street shops in Stockton and Darlington. The sales department also has a team of 15 mobile salespeople who move from region to region doing on-site sales around the country, typically in shopping centres or direct to larger business clients.

The network infrastructure itself has already been designed (see diagram) but no attempt has yet been made to create IP addressing schemes that would serve this network structure.

Your tutorial group will be divided into groups of up to 4 students, and each group will divide up the following four tasks between them (one task each).

1. If the firm was to use IP version 4 addressing for their company network:

l Create an IP scheme that would fully serve the company's host requirements.

l Recommend with good reasoning which routing protocol should be used.

2. If the firm was to use IP version 6 addressing for their company network:

l Create an IP scheme that would again fully serve the company network.

l Recommend with good reasoning which routing protocol should be used.

l Provide information on why the company should consider going straight to IPv6 rather than stick with IPv4.

3. Look into the placing of the following servers for the business – making sure that there is good reasoning from some research behind where they are supposed to go, and what additional network hardware may be needed: l A small server farm of 6 public WWW servers. l An intranet server for staff use only l A datacentre server.

l A set of backup servers to guard against the possibility of server/network failure.

4. Look into the needs for network security to keep company data safe and yet keep the all important sales WWW servers visible to the outside world:

l What network security hardware/software are needed.

l Where this hardware should be placed in the network.

l How should the network connections across the public Internet be defended and why.

l How to integrate the roaming salespeople securely into the network.

How you will be assessed

1. Group Presentation:

Put together a small presentation with no more than 2 slides for each of the areas being investigated – this should be styled as one coherent presentation, not 4 separate ones! These should be based on your findings and research. Each group will then present their findings to the strand tutors and the rest of the tutorial group during the tutorial session – first week back in January (Thursday 9^th January 2014).

Each member of the team must participate in the presentation in order to get a mark for it.

Your presentation will be marked according to the following criteria:

• Content of presentation matches the required area (10 marks)

• Presentation content demonstrates detailed knowledge of the topic (10 marks)

• Format and quality of slides (10 marks) • Verbal understanding of the topic (10 marks)

• Presentation skills (10 marks)

2. Individual Report

Each student must also submit a professionally written individual report outlining the findings of their personal investigation into their chosen area. The maximum length of the report should be 4 pages. This work must be completed individually.

The report should be uploaded into Sunspace no later than 5 pm Wednesday 8^th January 2014.

Your report will be marked to the following criteria:

For the IPv4 investigation:

• IPv4 scheme calculations showing working out (20 marks)

• IP scheme application to network (10 marks)

Your report must be a professionally written academic report, containing:

• Title page

• Table of contents

• Page numbers

• Section numbers

• Introduction

• Main section

• Conclusion

• Reference list and citations within the body of the report. These should be written using the Harvard Style of referencing – details of which can be found in the Sunspace.
