2.3 Models of an ICT system

To help me to introduce you to important ideas about ICT systems, I'm going to take a three-stage approach. ICTs involve conveying, manipulating and storing data. This is going to be the basis of my approach.

Firstly, in the next few sections, we'll look at ICT systems where the primary function is to convey data. We can think of these systems as communication systems and I'll use a mobile phone system as an example.

In sections 8–14, I'll focus on ICT systems wher

8.1.1 Visibility

Recall that a key usability design feature identified by Donald Norman – from his analysis of using everyday objects such as doors – was visibility. An everyday object such as a door, or a control such as a button on a product should appear to be obvious about how it is used, and indeed it should perform that obvious function. For example, is it obvious how you insert a disc into a player? Is it obvious how you switch the machine on, adjust volume, and so on?

The Civil War Battles
This video is accompanied by text. "With the beginning of the war still fresh in their minds, and expectations that fighting would be intense but short, Union troops were eager for action. Cries of “On to Richmond” echoed across the hills surrounding Washington as the troops advanced on Confederate forces near Bull Run, approximately 30 miles southwest of the northern capital.

7.1 Overview

Scottish literature is defined as literature written in Scotland or by Scottish writers, but is there such a thing as a literary and cultural identity which is distinctively Scottish?

2.2 Describing positions along a line

It is clearly convenient to measure the progress of the car with respect to the road, and for this purpose you might use the set of uniformly spaced red-topped posts along the right-hand side of the road (see Figure 5). The posts provide a way of assigning a unique position coordinate to the car
