DESCRIPTION - summary of the module content

***DEGREE APPRENTICESHIP STUDENTS ONLY***

This module provides an introduction to basic computer system organisation and network infrastructure with an overall focus on the services and capabilities that network infrastructure solutions enable in an organisational context.  You will gain the knowledge and skills that they need for the planning, design, implementation and management of computer networks and understanding of the network infrastructure capabilities and limitations.

AIMS - intentions of the module

The aim of this module is to ensure that you gain a good undersanding of the technology infrastructure used in business and government organisations. In particular, you will be able to demonstrate the following competences:

  • Can plan, design and manage computer networks with an overall focus on the services and capabilities that network infrastructure solutions enable in an organisational context.
  • Identifies network security risks and their resolution.
INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module you should be able to:

Module Specific Skills and Knowledge

1. Plan a computer system network based upon estimated business data traffic needs that will meet the future business needs

2. Analyse business and technical requirements and select appropriate network technologies and topologies as part of the network design

3. Identifying network security risks and their remediation

4. Give an overview of computer architecture and functions, CPU, memory, instructions, instruction cycle, I/O, interrupts, peripheral devices, instructions and memory architecture.

5. Explain how software is run and how operating system services create an interaction between hardware and software.

6. Describe the fundamental building blocks (e.g. routers, switches, hubs, storage, transmission) and typical architectures (e.g. server/client, hub/spoke) of computers networks and the Internet

Discipline Specific Skills and Knowledge

7. Explain what is meant by data and protocol and how they relate to each other.

8. Describe a data format and a simple protocol in current use.

9. Describe failure modes in protocols, for example reasons why a protocol may ‘hang’ and the effect on a protocol of data communication errors.

10 Describe the main features of a selected subset of network protocols in widespread use on the Internet and their purpose and relationship to each other, including the physical and data link layer  (e.g. https, HTTP, SMTP, SNMP, TCP, IP, etc.)

11. Explain some of main factors that affect network performance (e.g. the relationship between bandwidth, number of users, nature of traffic, contention) and propose ways to improve performance (e.g. application of traffic shaping, changes to architecture to avoid bottlenecks, network policy that prohibit streaming protocols).

12. Discuss issues that may arise in the day to day operation of networks.

Personal and Key Transferable / Employment Skills and Knowledge

13. Communicate orally and in writing

14. Solve problems creatively

15. Think analytically and critically

16. Organise your own work

17. Work to a deadline

18. Collaborate and negotiate

19. Make decisions

20. Conduct independent research

RE-ASSESSMENT NOTES

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be deferred in the assessment. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you may be required to sit a referral. The mark given for a re-assessment taken as a result of referral will be capped at 40%.
