2.2 Browsing for information on the Web One way to find what you are looking for on the Web is to start from sites that you know are likely to have useful ‘links’ on them, like the main Open University pages or the Open University Library pages. These opening pages are known as home pages and are a bit like the contents page of a book. The home page usually gives you some information about the content of the website, often with links to other pages of information held on that site and on sites elsewhere. By clicking on a link â
7.6 Researching information about RFID tags What is the smallest RFID tag currently available? Use the Web to see what you can come up with but don't spend longer than 10 minutes on this activity. (Hint: using ‘smallest RFID tag’ as the search term w 7.5 Active and passive tags Read the extracts below. Using the information they contain, make notes about the main differences between active and passive RFID tags. You will get more out of this exercise if you make a serious attempt to d 4.7 WiFi data rates and operating range Just as for Ethernet, developments in technology have increased the achievable data rates since the first WiFi standard was developed in 1997. At the time of writing, the latest WiFi standard to be published – IEEE 802.11g – defines a data rate of 54 Mbps. 5.1 The personal computer Over the following screens you will look at three different examples of computers: a PC, which is obviously a computer, and a set of electronic kitchen scales and a digital camera, which are not so obviously computers. You will find that all three of these examples match with the functional block diagram of a computer given in Author(s): 7.2 Difficulties in navigating e-commerce sites People who are new to computing sometimes find the process of online ordering baffling and frustrating. They get ‘lost’ in the process – for example, by putting something into a virtual shopping cart and then remembering that there's something else they need to look for. So they return to the search engine or the catalogue and then can't find the cart. These kinds of commonly experienced difficulties can be addressed by good and adaptive site design, but still a disturbing proportion of 2.1.1 What's ‘Buy It Now’? 2.4 Comparing early sources of news
Taylor compares the merits of radio and newsreels, as sources of news, with those of newspapers. 4.3.2 Plagiarism
Attempting to pass off someone else's work as your own is plagiarism.
You may be encouraged to use the Web as a resource for writing assignments. This does not mean you should copy chunks of text from other websites however. You can quote from other sites, but such quotes should always be acknowledged. You should write material in your own words, to demonstrate that you have understood it, rather than simply copying it. Using search engines it is relatively easy for markers to 1.6 Alternative ways to take notes Some people prefer to take notes in a non-linear way and to be able to visualise the connections between different ideas. Spray diagrams, mind maps, spider diagrams and concept maps are all ways in which to present ideas or information in a diagram rather than as text. They are essentially the same in terms of the structure, but are used for different functions. Mind maps and concept maps are used when developing your own ideas on a subject, for example when planning a report or 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. 1. Introducing the terminology Constructing enterprise systems is a complex engineering endeavour. As with other types of engineering, e.g. the construction of aircraft or suspension bridges, a lot of effort has to be put into planning and modelling, so that the final product is what is required and is achieved on time and within budget. Ben Kovitz (1999) makes a distinction between orderly and exploratory. Orderly engineering is characterised primarily by the application and slight variation of time-tested te 4.3 A commercial implementation In order to conclude this section I shall describe a commercial implementation of an object bus. It has been developed by a company known as SoftWired Ltd and is known as iBus. It is based on TCP/IP rather than UDP. The facilities offered by the iBus API provide developers with the facilities to construct objects which can subscribe to channels and to transmit any Java object to a channel. The code for a transmitter is shown below; the import statements are not shown.

Like a web server, a database server is a computer that responds to requests from other computers. Its task is to find and extract data from a database. The web and database servers form part of a distributed system. This means that separate computers exchange data and information across a network (in this case the internet) to produce results for a user. For 5.1.1 What is DNA? DNA (deoxyribonucleic acid) is frequently in the news for four main reasons. DNA can be used in crime detection to eliminate innocent suspects from enquiries or, conversely, to identify with a very high degree of probability the guilty. DNA is now used in medicine to detect the possibility that diseases having a genetic origin may occur in an individual. This enables doctors to prescribe preventative treatments.

Find out how your exam paper is set out, the way the questions are organised, and what weight each question carries in terms of marks. Different papers adopt different formats. Some require multiple-choice answers. Others ask for essay or short paragraph answers. Some require technical or numerical answers. Reading the instructions on the exam paper is particularly important, as the followi 1 The experience of reading The best way to develop your understanding of the reading process is to follow the principles of the Kolb learning cycle, by doing some reading and then reflecting on your experience. To this end, Activity 1 asks you to read an extract from an article by Richard Layard (2003) titled ‘The secrets of happiness’ which appeared in the New Statesman. To keep the task manageable I have reduced the article to half its original length and, for ease of reference, paragraph num
