Information and communication technologies: principles and perspectives IS2138

Information and communication technologies (ICTs) are the foundation for virtually all modern computing applications.

The creation of such an ICT system raises many complex questions such as how an ICT is used, how an ICT stores data, and how an ICT communicates. Three complementary topics, or elements, concern these issues and form the basis for this course: human-computer interaction (HCI), databases and network technologies.

Prerequisites/ Exclusions

If taken as part of a BSc degree, courses which must be passed before this course may be attempted:

  • IS1060 Introduction to information systems and either
  • IS1168 Introduction to computer systems architecture and programming or
  • IS1129 Introduction to programming.

Exclusion

This course may not be taken with:

  • IS2182 Innovating digital systems and services.

Topics covered

There are three topics in this course. However, rather than approaching these as separate, individual themes, this course presents them as a single, integrated topic that will assist you in the creation of ICT supported applications. This course therefore considers these topics to be key elements of ICTs.

These are:

Human Computer Interaction (HCI): This will introduce you to HCI and interactive systems design from an ICT perspective and show how issues in HCI are fundamental to good ICT design. It will examine how issues for interactive systems design arise from the psychological, social and organisational context of interaction. Current research issues in HCI will be considered where they impact on the use and future development of ICTs; notably, this will cover issues in mobile and pervasive computing, social media and social networking. In order to design effective interactive systems around these contexts, a detailed review of the tools and techniques for interaction design will be considered, covering user-centred design, prototyping and usability evaluation.

Databases: This aims to provide you with an understanding of the main issues related to data modelling, storage and manipulation as employed in database systems. The subject will mainly focus on the theory and practice of the relational model. It will also discuss challenges of managing databases, and recent and emerging trends in database systems.

Distributed multimedia systems: In ICTs, communication and the media through which it is achieved are fundamental. This element aims to provide you with an understanding of the main issues involved in the digitisation, storage and transmission of digital media to an ever-increasing array of devices via a diversity of communication pathways. The increasingly mobile nature of such pathways leads to the possibility of building context-aware applications and we shall be looking at the challenges and opportunities that such applications provide. Last, but not least, security is an important aspect of networked communication, and we shall also be covering its main principles and safeguards.

Learning outcomes

If you complete the course successfully, you should be able to:

  • Describe the increasing role of interactive systems in computing and systems design
  • Describe the key cognitive, social and organisational concepts that underpin how humans interact with information technology
  • Discuss various theoretical and practical approaches to HCI
  • Identify important technology developments in the domain
  • Show an awareness of the HCI viewpoint that places the user at the centre of the design
  • Explain and apply a variety of approaches to HCI design, showing an understanding of their benefits and drawbacks within the design process
  • Apply appropriate user-centred design process and methods (e.g. iterative prototyping, usability evaluation, user centred design) to assess and alleviate any problems their users face
  • Demonstrate understanding of key concepts and applications associated with the tree-level ANSI-SPARC architecture, DBMS, multi-user DBMS architectures, relational and object-oriented data models
  • Employ conceptual data modelling techniques for the specification of data requirements and evaluate which are most appropriate to given application problems
  • Describe key elements of a database language and demonstrate how these are used to manipulate data in a database
  • Discuss challenges faced in designing and managing databases, including security and transaction management
  • Demonstrate an understanding of key issues and technologies involved in business intelligence describe the fundamental requirements of a successful distributed multimedia system
  • Discuss how distributed multimedia systems might be designed and implemented, highlighting the major problems that are involved in operating and inter-operating distributed multimedia systems
  • Identify and explain the fundamentals of a range of multimedia technologies and systems
  • Discuss the principles and requirements of secure communications
  • Describe and contrast the use of Public and Private Key Cryptography in secure communications.
