2.4 Information and communication technologies

The new economy is much more than a shift from manufacturing to services and the increased integration of economies on a global scale. It is also strongly linked to the development of ICT, which has facilitated the development of new processes and products, especially ‘knowledge goods’ which are described below.

The internet has increased the ‘connectivity’ or interconnectedness between economies by making textual communication possible in real time as well as providing a new me

6 Conclusion

As you moved through the various techniques we can use to analyse media texts in Sections 2 to Section 4, you should have discovered how rich even the simplest text can be in its drawing on political, social and cultural meanings discernible by close attention. Textual analysis enables you to register and negotiate the polysemy of texts and to see how the preferred reading is not the only one available. The preferred reading may be given prominence, however, by anchoring or by the genre chose

4 What is a ‘nation’?

Guibernau (1996, p. 47) has defined the nation as: ‘a human group conscious of forming a community, sharing a common culture, attached to a clearly demarcated territory, having a common past and a common project for the future and claiming the right to rule itself’. So awareness, territory, history and culture, language and religion all matter. However, it is rare in the real world to find a case of a nation with a clear-cut and homogenous character in terms of this list of possibilities.

Digital communications
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.Author(s): Creator not set

2.1 Numbers

The supermarket example discussed in Section 1 involves various forms of data that a computer may need to handle. Some of these, such as numbers and characters, are simple but fundamental. Other forms of data, such as sequences, involve more complicated structure. In this section, we will introduce sets, which are a variety of data collection that is different from sequences. But first we will look more carefully at numbers and characters.

17.4 The database server

The computer block on the right represents the database server, which is dedicated to managing a database and making the data available to other computers in the network. The database server receives data via the network. It stores, retrieves and manipulates data, for example by retrieving your previous points total and adding to it the number of points you have ‘earned’ on this visit. This data is also sent back via the network to the checkout computer to show you the total number of poi

2.1 Introduction

There are many types of system – not just ICT systems. For example, we all have a nervous system and, as you are studying T175, you are in a higher education system. Our homes have plumbing systems and electrical systems.

4.2 Information in an e-business age

Sharing information in business is itself a risky business. The information that is exchanged between b2b partners, for instance, may include order information, customer details and strategic documents. Such information could be priceless to outsiders. As you saw in the previous section, huge costs can result from information getting into the wrong hands.

In sharing information, an organisation also needs to be aware of the various laws, regulatory frameworks and codes of practice. Fail

2.1 Networked devices you use every day

The next activity aims to get you thinking a bit more about how ICT systems form part of your own life and to make you more aware of how you are living in a networked world. ICT systems are embedded in many everyday experiences and we have become so used to this that we hardly notice that we are using them.

7.4.1 Architectural patterns

A software architecture is the broad structure of a software system. It describes its parts and how they are put together, and also captures an underlying rationale and associated concepts, such as professionalism (liability) and constraints (such as standards and economics). The term architecture is, again, reminiscent of its use in buildings.

Architectural patterns (also known as architectural styles) codify recurrent software architectures by describing the key

7.2.13 Online trading

This business model encompasses the trading of financial instruments such as bonds and stocks via the internet. Online trading has been a feature of the financial industry for some time. However, it was carried out using internal networks. The internet has enabled the individual user to trade stocks and shares from home and has given rise to the term day trading.

8.5 Reviewing

Undoubtedly this is the most difficult phase to apply to revision and an exam or to the preparation and production of an end-of-course assessment. Most of us heave a huge sigh of relief when it is all over and then try to put it out of our minds during the weeks while we wait for the results. When these arrive, it is very difficult to think back to the exam itself or revisit the details of the end-of-course assessment. With very little feedback to help, learning how to learn from exams or the

4.9 When there's too much to do

This can be a real problem in large conferences. If, for whatever reason, you join a conference later than the other participants, or are unable to be involved for a while, the prospect of joining in can be a bit daunting. There will be lots of messages you haven't read and you may feel that everyone else knows each other.

The main thing to remember is that everyone will be pleased to ‘see’ you when you do join in, and will be helpful and supportive. Here are some strategies you can

3.3 Real time chat

Online chat is a means of having a quick written conversation with one or more people who are online at the same time. Compared with email, there's less of a time lag in waiting for a response. Messages are likely to be more spontaneous, and it can be anarchic when several people reply at once.

2.3 Learning more

Consider your main use for the PC, and check that you have the skills or knowledge you need. Although some students use spreadsheets and databases, the key skills for most students are:

  • word processing study notes and assignments;

  • searching for information on the web;

  • using conferencing and email.

If you feel you need to know more about using your computer there are a number of options open to you.
