ITEC101 - Computer Networks

Unit rationale, description and aim

Almost all computing devices from super computers to personal computers and even to mobile devices are connected using computer networks. The rapid advancement of communication technologies and the long-established use of local area networks have made the study of computer networks as important as the more traditional foundations of information technology such as computer architecture and programming. There is a need of professionals who exercise knowledge and leadership in the area of computer networks and its applications. This unit covers the fundamental topics of computer networks and data communication. The unit demonstrates the basic networking concepts, OSI and TCP/IP networking model, functionalities and characteristics of different layers, network devices, and protocols. Students will learn how these devices and protocols are used in computer networks and application programs. The practical works will help students to learn how to design, configure, build and test a small-scale peer-to-peer network for an organisation. In addition, the unit focuses on designing a network solution that utilises optimal resources and thus, aims to minimise negative impacts on the environment.  

In a nutshell, the unit aims to equip students with background knowledge in computer networking, which scaffolds an advanced unit in emerging technologies of blockchain and IoT. It will produce graduates with i) a wide range of professional knowledge and skills relevant to networking and communication technologies, ii) adaptability to changing technology and society, iii) capability to design network solutions utilising minimal computing resources.

Learning outcomes

To successfully complete this unit you will be able to demonstrate you have achieved the learning outcomes (LO) detailed in the below table.

Each outcome is informed by a number of graduate capabilities (GC) to ensure your work in this, and every unit, is part of a larger goal of graduating from ACU with the attributes of insight, empathy, imagination and impact.

Explore the graduate capabilities.

• Subnetting
• Transport layer
• Application layer
• Build a small network.

Learning and teaching strategy and rationale

Mode of delivery: This unit is offered mainly in ‘Attendance mode’ with aspects of ‘Multi-mode’ incorporated into the delivery to maximise the learning support offered to students. Students will be required to attend face-to-face workshops in specific physical location/s (including supervised lab practical sessions) and have face-to-face interactions with teaching staff to further their achievement of the learning outcomes. This unit is also structured with some required upfront preparation before workshops – learning materials and tasks set via online learning platforms. This will provide multiple forms of preparatory and practice opportunities for students to prepare and revise.

Further to this, to ensure students are ready to transition from the Diploma and articulate into the second year of undergraduate study, transition pedagogies will be incorporated into the unit as the key point of differentiation from the standard unit. This focuses on an active and engaging approach to learning and teaching practices, and a scaffolded approach to the delivery of curriculum to enhance student learning in a supportive environment. This will ensure that students develop foundation level discipline-based knowledge, skills and attributes, and simultaneously the academic competencies required of students to succeed in this unit.

Students should anticipate undertaking 150 hours of study for this unit, including class attendance, readings, online forum participation and assessment preparation.

Assessment strategy and rationale

A range of assessment procedures will be used to meet the unit learning outcomes and develop graduate attributes consistent with University assessment requirements. The first assessment item consists of a number of weekly labs designed to give students practical knowledge of installing, configuring and troubleshooting network devices as well as planning and building a small network. The second assessment task will help to gain practical knowledge on subnetting which ensures optimal uses of network resources. The final assessment item includes a case scenario where students need to apply their knowledge and skills to find configuration errors, and apply patches to make the network operational.

Strategies aligned with transition pedagogies will be utilised to facilitate successful completion of the unit assessment tasks. For each assessment, there will be the incorporation of developmentally staged tasks with a focus on a progressive approach to learning. This will be achieved through activities, including regular feedback, particularly early in the unit of study to support their learning; strategies to develop and understand discipline-specific concepts and terminology; in-class practice tasks with integrated feedback; and greater peer-to-peer collaboration. 

The assessments for this unit are designed to demonstrate the achievement of each learning outcome. To pass this unit, students are required to:

• obtain an overall mark of at least 50% 
• attempt all three assessment items.
