1 Describing an ICT system
In this course I shall be introducing you to some ideas about how ICT systems work. Because this course is about ICT systems, I'll be starting with a discussion about what constitutes a system. I'll go on to introduce some diagrammatic ways of representing ICT systems. Then I'll look at some examples to illustrate how they carry out certain processes, namely conveying, storing and manipulating data. You will also find out about other processes performed by ICT systems.
In this section I'll start by discussing how taking a 'systems' view of ICT systems can help our understanding of them. Later in the session. I'll be focusing on the communication component of an ICT system.
