6.2 Who should get to vote on secession?

The Bs (encompassing the Cs) or all the As too? After all, democracy is often said to be about people who are affected by an issue having a say on it; and As will certainly be affected if Bs secede. This is a live issue with regard to Northern Ireland's future, for example. If a referendum were to decide if the province should join the Irish Republic, should the voters include all UK voters and all Irish voters, or just those living in the province? If, for example, there were to be a vote on

3.4 Input and output considerations

CCDs are not inherently able to detect colour, only brightness. So it is necessary to rely on the fact that any colour of light can be made up from the three primary colours of light: red, blue and green. (Note that the three primary colours of light are different from the three primary colours of pigments.) Each CCD in the array is therefore overlaid with a red, blue or green filter and so detects the brightness of, respectively, the red light, the blue light or the green light falling on it

2.4 Representing numbers: negative integers

In Section 2.2 I showed you how integers can be encoded if they are known to be positive, treating the integers in the kitchen scales as if they were known to be positive. However, if the user invokes the ‘add-and-weigh’ function on the scales while there is an object in the scalepan and then removes th

16.1 Introduction

Supermarkets make use of ICT systems for a range of purposes. In the following sections, we'll look at the processes of receiving, storing, retrieving, manipulating and sending data at the checkout, and then we'll move on to the larger context of the supermarket.

12.1 Introduction

Data must be stored somewhere when it is not being manipulated. Modern ICT systems require increasingly large amounts of data to be stored for later use, and it is important that the data can be accessed quickly. Data may be stored on the stand-alone computer's hard disk in the form of files.

You may want to move files from one stand-alone computer to another. In addition, you may want to move files from a device, such as a digital camera, to a computer. These activities require some fo

9 A stand-alone computer

The computer you are using for your studies is called a personal computer or PC. Although you have an internet connection for use in this course, your computer can probably also be used as a stand-alone computer. Your PC may be a desktop computer or a notebook computer (sometimes known as a laptop computer). Usually a desktop computer comes with separate devices such as a monitor, a keyboard, a mouse and speakers and it runs on mains electricity. Notebook computers

4.7 Identification errors and the national database

The UK identity card scheme, and similar schemes in many other countries, is based on the idea of creating a national identification register. This is a database that will have templates of biometric data from all citizens. In the UK, the proposal is to have a photograph, some fingerprint data and iris scans from each citizen. There will also be other data in the register: name, address, national registration number, and much more besides. Identity cards will be issued only to people who are

Other approaches to information security management

Many of the approaches to planning an ISMS to be found in the literature follow a three-phase, rather than a four-task, approach. For instance, Moses (1994) stipulates seven steps in three phases:

  • initiation: the identification of information assets and their security requirements;

  • analysis: the identification of possible risks to the security requirements of information assets, of the vulnerabilities to those risks, and

2.3 What is information security management?

Information security management is the process by which the value of each of an organisation's information assets is assessed and, if appropriate, protected on an ongoing basis. The information an organisation holds will be stored, used and transmitted using various media, some of which will be tangible – paper, for example – and some intangible – such as the ideas in employees' minds. Preserving the value of information is mainly a question of protecting the media in which it is

5.4 Set-up, maintenance and power requirements

Issues for set-up and maintenance include:

  • Cost (what are the costs of setting up and maintaining the technology?)

  • Availability of components (are components readily available?)

  • Interoperability (will devices from different vendors work together?)

  • Continuity of supply (will components still be available for a reasonable period in the future?)

Because of its greater range and complexit

8 Online shopping – what it means

Shopping online is already very big business, and is growing rapidly. This suggests that the concerns of consumers discussed earlier are being addressed by the industry. People wouldn't shop online if they didn't trust it. But in a way the most profound impact of online retailing is being experienced in the ‘real’ world. According to the Economist magazine, for example, the Internet is profoundly changing consumer behaviour in the real world.

7 Summary

The theme of this unit has been the impact that information and communication technologies have had on the news industry. I introduced this theme with a short historical overview of technology in the news industry followed by a look at how technology is used for newsgathering.

We have been looking in some detail at aspects of the underlying technologies used in newsgathering, including the basic components of digital camcorders and the methods of signal transmission over wires. We have

6.2 Authority and the variety of information sources

Technology has massively increased the number and variety of news sources that we have access to. We still have printed books, magazines and newspapers, while digital techniques have increased the number of broadcast radio and TV channels that we can get. On the Web we have access to online versions of many of these. This allows us access to media that previously would have been inaccessible.

With traditional news sources such as these, we have some understanding of the authority that t

2.1 Communication technologies

With the Industrial Revolution the idea of ‘news’ developed rapidly, and these days most people in the UK and other developed countries have concept of ‘the news’. We expect to be kept up to date with the news through various sources, and to satisfy this expectation we have the businesses of newsgathering and dissemination of news.

In this section you will be learning about the development of the technologies used for newsgathering and dissemination by reading extracts from a pa

1.3 When is the right time to take notes?

Any time that suits you! Increasingly we live in an age where there is more information than we can possibly hope to deal with. One of the most important skills you (or any of us) can develop is how to cope with all this information. Note taking is just one skill that will help you do this. It is important to get into the habit of making notes, and the best way to do this is to find a method that suits you (and the medium you are working in).

8.3 Entities

Here is the definition of an entity.

An entity represents a thing that has meaning in a given context and about which there is a need to record data.

A data model is not concerned with the individual entities. Instead, it describes particular types of entity. For example, all students are represented by the same types of data (student identifier, name, whether or not registere
