1.6.2 Alerts

Online bookshops and some of the major search engines offer ‘Alerts’ services. These work by allowing you to set up a profile once you have registered on their site, and when there are items meeting your criteria you receive an email. The good thing about alerts is that you don’t have to do anything once you have set up your profile. The downside, particularly with alerts services from the search engines, is that given the extent to which internet traffic is on the increase whether new

1.4.1 PROMPT

There is so much information available on the Internet on every topic imaginable. But how do you know if it is any good? And if you find a lot more information than you really need, how do you decide what to keep and who to discard?

In this section we are going to introduce a simple checklist to help you to judge the quality of the information you find. Before we do this, spend a few minutes thinking about what is meant by information quality.

1.3.10 Choosing the right tool for the job

Before searching it is always a good idea to check what the source you have chosen covers to make sure it will unearth information that matches your search need (you will notice that all the resources we’ve covered in this guide have short descriptions to enable you to decide which to use). Some of the decision makers, depending on the context of your search might be:

  • Does it have full text?

  • Does it cover the right subject?

1.2 The hard side of Glasgow

Prior to its currently projected image of dynamism, Glasgow was regarded as the place which best illustrated all that was wrong with the modern industrial city: ‘Once called the “second city of the British Empire” because of its size and industrial might, Glasgow had sunk so low that even the locals disdained it’ (Bryson, 1989).

1.1 Why Glasgow?

Glasgow fulfilled our aims and was also an interesting case study having, arguably, been the most successful among British cities in developing/manufacturing a new identity in the ‘post-industrial’ era. Glasgow illustrates:

  • (a) power relations, reflected in:

    • constructed images – ‘Glasgow's miles better’ was a deliberate campaign to improve the image of Glasgow.

    • contested images –

8 Summary

In this unit you have learned about the difference between the analogue world we inhabit and the digital world of the computer.

I've described how features of our world can ‘cross the boundary’ and be represented or modelled in the digital world, and then brought back across the boundary to us.

More excitingly, computer programs that manipulate digital representations of our world enable us to:

  • simulate physical and social processes;

4.2.1 First computer (your computer)

In the block diagram, the computer receives data from the user and sends it into the network. It will manipulate and also store and retrieve data.

If you send a message to a FirstClass conference, your computer receives the message from you as data via the keyboard. The computer manipulates the data into a form that can be sent into the network, in this case the internet via your internet service provider (ISP). Your computer will also store or retrieve relevant data, such as details of

10.2 Ports

On the outside of a computer you will see a number of connection points that look like sockets. These sockets are known as ports and they provide connections between the computer and external devices such as a digital camera or printer. Ports control the flow of data between the computer and these devices, ensuring that data is sent and received quickly and reliably.

Modern ICT devices require increasingly large amounts of data to be sent between the computer and the devices. The

10.1 Introduction

A stand-alone computer receives data from a user by means of input devices. The two most commonly used input devices are the keyboard and the mouse. A computer sends data to a user by means of output devices. Data may be output via devices such as a screen or a printer.

There are many different ways of getting data into a computer. For example, a scanner converts images and texts into a format that can be processed by the computer and displayed on screen. Devices such as t
