We will introduce you to a design methodology to help develop linear and hierarchical trains of thought from idea conception through design and implementation to testing. You will use a simple interactive programming environment to discover how to create and use a wide variety of different basic and complex data structures. By the end of the module, you will be able to analyse a simple set of requirements, design appropriate data structures, select appropriate language syntax to manipulate program data and understand and use syntax for the implementation of conditional logic and repetition. You will also be able to create simple scripts, demonstrate familiarity with the taxonomy of programming languages and the software development life- cycle and gain sufficient experience of a range of algorithm design techniques.

If you are anticipating a career in information systems or programming, the knowledge of website construction, whether that is for the internet or a company intranet, is a valuable asset. Our module provides you with the knowledge required to build a standards compliant web site. The website will be a blend of XHTML, Cascading Style Sheet and a scripting language and incorporate media and text elements. You will also be expected to submit documentation containing an introduction, descriptions of the purpose and aims of the web site. You will choose a subject for the website. The knowledge you will gain in this module will form the foundation for further web-based study in areas such as graphic design, user perceptions of the usability and quality of web pages and multimedia/database websites.

This module is essential for the student who needs a solid background in basic mathematical techniques and analysis in order to pursue a degree programme in technology. The module will help students to assess their existing mathematical skills and sympathetically enable them to remedy any basic deficiencies. It will then develop the core mathematical skills needed for successful study at degree level in technology, and also provide a basis for those students wishing to undertake further mathematical study. The module will be assessed by two in-class tests.

You will be introduced to the fundamental features of modern operating systems, their components and their use. You will learn key concepts including the kernel, memory and resource management, security and authentication, and command line and graphical user interfaces (GUI). Case studies will be used to familiarise you with the history and features of Windows/MS-DOS and Linux/Unix. The module will also introduce you to the command line interface (CLI) commands and scripting in both the Windows CLI and a Linux shell and allow you to develop simple scripts to automate activities in both operating system environments. It will also explain how each operating system stores configuration information and how (particularly in Linux/Unix) scripts can be used to modify that system configuration. The skills acquired in the module will enable you to go on to study modules which involve topics such as system administration, network and server configuration, and technical support, all of which are key skills graduates need when working in the systems and network support industries.

This module introduces students to the components and requirements of modern networked computer systems. In order to understand how such systems work it is necessary to consider the operating system, through the networking technology to the servers to be accessed. On completing this module, students will be able to specify, construct and maintain networked PC systems, and troubleshoot common hardware and software problems. Practical skills are underpinned by a sound theoretical foundation in computer systems and network architecture, including both local area networks (LANs) and wide area networks (WANs). Theoretical topics will be delivered in weekly lectures that will be consolidated through significant self-study. Laboratory sessions will enable students to gain the practical skills needed to construct, maintain and troubleshoot problems on networked computer systems. Students’ progress is assessed via a submitted laboratory log-book, an in-class test, and a written coursework assignment.

Information technology has created a world that is increasingly virtual in nature. Both private individuals and businesses alike suffer the same vulnerabilities in managing access to valuable information that is increasingly being stored remotely. Whilst the public and industry professionals wrestle with the escalating complexity and variation in the ways that information is compromised, we see the emergence of the harnessing of digital insecurities as a weapon on an international stage. You will be introduced to some of the key concepts that lie at the heart of information security, but viewed at the more fundamental data level. You will be provided with a critical insight into the often misunderstood or poorly defined issues of data security and thereby offered a springboard to the study of information security at level 6. After studying this module you will understand how and why the digital data systems we use every day pose such a threat to individuals and businesses, where solutions are possible and where they might prove difficult or impossible. A key issue is the fundamental weakness that humans introduce into the technology. You are expected to augment the content delivered by lectures with independent study of your own on a weekly (or even daily basis) in order to remain current with developing threats. You will write up a dossier of weekly security issues and together with a 1,000 word technical discussion of a particular security vulnerability will form the final assessment making a 3,000 word submission in total.

Computer networks are constantly evolving to keep pace with the changing needs of organizations in supporting their daily business. Users now expect instant access to company resources from anywhere and at any time. These resources not only include traditional data but also audio and video and voice. There is also an increasing need for collaboration technologies that allow real-time sharing of resources between multiple remote individuals as though they were at the same physical location. The global Internet is a collection of networks, termed Autonomous Systems (AS), that are linked together via high-speed communication links provided by telecommunication organisations. LAN switches provide the connection point for end users into the enterprise network and are also primarily responsible for the control of information within the LAN environment. Routers facilitate the movement of information between LANs and are generally unaware of individual hosts. Due to the complexity and dynamic nature of networks, often networks employ dynamic routing protocols to dynamically establish the "best" path for routing the traffic, to achieve the maximum efficiency while maintain the ever-increased demand of reliability and security. This module focuses on the key concepts and protocols of network routing and switching. It covers basic routing and switching concepts, including static and default routing, Virtual Local Area Networks (VLANs), and inter- VLANs routing. Dynamic protocols such as RIP, EIGRP and OSPF, and will be discussed and explored Network security using Access Control Lists will be introduced and the wider issues of network and Internet security considered. Other topics such as DHCP and NAT will also be covered. The module is delivered as a mixture of theory, delivered through a series of lectures, and practical implementation, delivered through a series of guided laboratory exercises. In the lab sessions students will gain deep understanding on the routing and switching concepts with an emphasis on their hands-on-skills using hardware equipment in the laboratory and advanced network simulation tools that comply with industry standards. The module is assessed by a case study based assignment and an in-class test. The case study will be centred on the design and implementation of a routed and switched network, comprising both local and wide area networks. The in-class test will consist a set of well-constructed multiple choice questions to test students’ understanding of routing and switching concepts and theories.

Much of the traffic on the Internet and an increasing amount of traffic within a business is streamed media. This traffic may be made up of video clips from sources such as YouTube or Lynda, catch up services such as iPlayer or Now TV, business applications such as VoIP and video conferencing or the real-time streaming of concerts or world events. This module will look at the infrastructure, protocols, encoding, encapsulation and applications used in the streaming of media. The module starts by considering the effect of bandwidth on the rate at which data can be sent over a medium and then considers the data rate required by a variety of different types of audio and video media. The way in which the media is encoded, compressed and encapsulated is then investigated and the resulting bandwidth requirements discussed. Issues and approaches to multicasting are considered as are the protocols that are commonly used for real-time streaming. This will include the techniques and protocols of VoIP and video conferencing as well as architectures based on technologies such as uPnP, DLNA and Miracast. The techniques, protocols and applications will be presented and discussed in the lecture whilst the practical will be used to implement, configure and analyse streaming applications so the network traffic and performance of the end devices can be assessed. The module will be assessed by a logbook that will be created throughout the course of the semester and an end of semester examination.

You will develop critical business and financial skills, as well as attitudes and behaviours to help you succeed. You will learn key concepts through business case studies and computer game based activities. By applying, practicing and ultimately mastering fundamental skills through the case studies and activities, you will develop an entrepreneurial mind-set that empowers you to improve your overall quality of life. You will be evaluated through five interactive, online case studies designed to help you apply IT capabilities within the context of starting a business. These case studies introduce a variety of basic business and financial concepts through hands-on exercises and realistic scenarios that cultivate and reinforce the critical thinking skills required to become a successful entrepreneur. The computer-based interactive learning game will challenge you to apply and practise the business and financial skills introduced in the case studies within the context of simulated networking environments. The game will invite you to explore, learn and develop entrepreneurial thinking, creative problem-solving and decision-making skills that will help you successfully compete in the global marketplace. You will be assessed through interactive, online case studies with presentation and submission of presentation notes in addition to a substantive individual report. This module will also provide you with “soft” skills that are nowadays much needed in the industry.

This module is essentially a mini project where you will design some artifact, e.g.: electronic hardware, software, multimedia production, website etc. The management of the project is in itself a core element and you are expected to produce a formal specification using sound design methods, a time plan and progress indicator. You will also be expected to produce a number of alternative designs that meet the specification, select the most appropriate design using recognised techniques and carry out design reviews.
