8.5 The exclusive-OR operation The exclusive-OR operation (usually abbreviated to XOR, pronounced ‘ex-or’) combines two binary words, bit by bit, according to the rules: 0 XOR 0 = 0 0 XOR 1 = 1 1 XOR 0 = 1 1 XOR 1 = 0 In other words, the result is 1 when either bit is 1 but not when both bits are 1 or both bits are 0, or the result is 1 when the two bits are different and 0 when they are the sam
8.3 The AND operation The AND operation combines two binary words bit by bit according to the rules 0 AND 0 = 0 0 AND 1 = 0 1 AND 0 = 0 1 AND 1 = 1 In other words, only when both bits are 1 is the result 1. You may find it helpful to think of it this way: when one bit is one and the other bit is 1 the result is 1. 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 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. 1.1 Data and information Although this unit is about ICTs, the technologies you'll be learning about do not actually handle information. Instead they handle data. In everyday language the terms ‘data’ and ‘information’ are often used interchangeably, but it is important to understand the difference when you are studying ICTs.
Data is a representation of information so that it can be conveyed, manipulated or stored. Information is the meaning that people give to data in particular contexts Learning outcomes After studying this unit you should be able to: describe some of the architectural and programming paradigms used in distributed system development; describe message passing and the role of protocols within a message passing paradigm; introduce the concept of a distributed object; describe how event-based architectures are used within distributed system development; introduce one implementation of an event-based archite 7.2.16 Free products and services It might seem paradoxical to include sites which provide free products or services under the category of business models. Typical sites which come under this category include gaming sites where users can play computer games using their browser, sites which run free raffles and sites which offer free software. Such sites do not earn any revenues from the products or services they offer; revenue is earned indirectly, for example by means of banner adverts or by receiving revenue from site 3.2 Answering the question An essay can be good in almost every other way and yet be judged poor because it ignores the question in the title. Strictly speaking, I should say ‘it ignores the issues presented in the title’ because not every essay title actually contains a question. But, in fact, there is usually a central question underlying an essay title, even when it takes the form of a quotation from a text followed by the instruction ‘Discuss’. And you need to work out what that underlying question is, beca Introduction Interpersonal communication in health and social care services is by its nature diverse. As a consequence, achieving good or effective communication – whether between service providers and service users, or among those working in a service – means taking account of diversity, rather than assuming that every interaction will be the same. This unit explores the ways in which difference and diversity impact on the nature of communication in health and social care services. This materia 3.1 Doctors: the ‘Great-I-Am’ We pin a lot of hopes on doctors. We expect them to know all that is relevant about the classification and treatment of diseases. We expect them to be able to make us better, and to give us an indication of what will happen to us next. There are strong pressures on doctors to respond to this expectation – to be knowledgeable and confident, to set themselves apart from ordinary mortals. Lesley Mackay is a researcher who, in 1989–90, carried out an extensive study involving over a hundred i Learning outcomes After studying this unit you should be able to: identify the different approaches and contributions staff make to care for health in a hospital setting; evaluate the interpersonal relationships of those working together for health in a hospital setting; appreciate how patients might experience care for health in a hospital setting. 3 Audio activity The three clips included in this section are taken from interviews with parents who contributed to the development of the Bedfordshire branch of Mencap. As you listen to the clips, make notes on why change was needed, and on what pressures for change the speakers mention.

You probably have a sense of a rather inert (and, perhaps, hard to shift!) tissue acting as a long-term energy store, but this is only a small part of the story. Adipose tissue consists of individual fat cells (adipocytes (Figure 12)) togeth 6.2.4 The speed and direction of the Earth's motion The first significant claim to have detected the motion of the Earth relative to the ‘frame of isotropic 3 K radiation’ came in 1977 from a group at Berkeley, California. They concluded that the Earth is moving at a speed of (390 ± 60) km s−1, in a direction towards the constellation Leo, relative to a frame in which the 3 K radiation is isotropic. Their conclusion resulted from observations of a variation of intensity with angle of the form predicted by Equation 14, which w 1.10 Subtraction of decimal numbers Subtraction of numbers can be used to answer questions such as ‘what's the difference between two values?’ or ‘if something has decreased by a certain amount, what's its new value?’ Subtraction can also be thought of as undoing the process of addition. For instance, instead of saying ‘£10 take away £7.85 leaves how much?’ you could say, ‘what do I have to add to £7.85 to get back to £10?’
5.6 The importance of size and habitat The use of hibernation to gain energetic advantage must be weighed against a number of considerations, particularly animal size and behaviour, biogeographic distribution and habitat. Small animals, which can carry less fat and have a higher surface area to volume ratio and BMR, are more likely to lose energy as heat and in maintaining life functions if they do not use hypothermic strategies in winter. Few hibernating mammals have a total body mass greater than 5 kg. Indeed, in large animals t
