The Computer A Very Short Introduction

There is a companion web site asssociated with the book (http://vsicomputer.wordpress.com/). It contains chapter summaries, links to relevant material and posts about items of news relevant to the book's contents. Computers have changed so much since the room-filling, bulky magnetic tape running monsters of the mid 20th century. They now form a vital part of most people's lives. And they are more ubiquitous than might be thought - you may have more than 30 computers in your home: not just the desktop and laptop but think of the television, the fridge, the microwave. But what is the basic nature of the modern computer? How does it work? How has it been possible to squeeze so much power into increasingly small machines? And what will the next generations of computers look like? In this Very Short Introduction, Darrel Ince looks at the basic concepts behind all computers; the changes in hardware and software that allowed computers to become so small and commonplace; the challenges produced by the computer revolution - especially whole new modes of cybercrime and security issues; the Internet and the advent of 'cloud computing'; and the promise of whole new horizons opening up with quantum computing, and even computing using DNA.

While the development of information technology has been obvious to all, the underpinning computer science has been less apparent. Subrata Dasgupta provides a thought-provoking introduction to the field and its core principles, considering computer science as a science of symbol processing.

Very Short Introductions: Brilliant, Sharp, Inspiring This lively Very Short Introduction reviews the central events, machines, and people that feature in established accounts of the history of computing, critically examining received perceptions and providing a fresh look at the nature and development of the modern electronic computer. The book begins by discussing a widely accepted linear narrative of the history of computing, centred around innovatory highlights that start with the use of knotted cords to aid calculation, all the way to the smartphones of the present day. It discusses the problems and simplifications present in such a narrative, and offers instead an account, centred on users, that identifies four distinct historical threads: calculation, automatic computing, information management, and communication. These threads are examined individually, tracing their paths and the convergences of related technologies into what has come to be called 'the information age'.

Since long before computers were even thought of, data has been collected and organized by diverse cultures across the world. Once access to the Internet became a reality for large swathes of the world's population, the amount of data generated each day became huge, and continues to grow exponentially. It includes all our uploaded documents, video, and photos, all our social media traffic, our online shopping, even the GPS data from our cars. 'Big Data' represents a qualitative change, not simply a quantitative one. The term refers both to the new technologies involved, and to the way it can be used by business and government. Dawn E. Holmes uses a variety of case studies to explain how data is stored, analysed, and exploited by a variety of bodies from big companies to organizations concerned with disease control. Big data is transforming the way businesses operate, and the way medical research can be carried out. At the same time, it raises important ethical issues; Holmes discusses cases such as the Snowden affair, data security, and domestic smart devices which can be hijacked by hackers.

The applications of Artificial Intelligence lie all around us; in our homes, schools and offices, in our cinemas, in art galleries and - not least - on the Internet. The results of Artificial Intelligence have been invaluable to biologists, psychologists, and linguists in helping to understand the processes of memory, learning, and language from a fresh angle. As a concept, Artificial Intelligence has fuelled and sharpened the philosophical debates concerning the nature of the mind, intelligence, and the uniqueness of human beings. In this Very Short Introduction , Margaret A. Boden reviews the philosophical and technological challenges raised by Artificial Intelligence, considering whether programs could ever be really intelligent, creative or even conscious, and shows how the pursuit of Artificial Intelligence has helped us to appreciate how human and animal minds are possible.

From ecosystems to Facebook, from the Internet to the global financial market, some of the most important and familiar natural systems and social phenomena are based on a networked structure. It is impossible to understand the spread of an epidemic, a computer virus, large-scale blackouts, or massive extinctions without taking into account the network structure that underlies all these phenomena. In this Very Short Introduction, Guido Caldarelli and Michele Catanzaro discuss the nature and variety of networks, using everyday examples from society, technology, nature, and history to explain and understand the science of network theory. They show the ubiquitous role of networks; how networks self-organize; why the rich get richer; and how networks can spontaneously collapse. They conclude by highlighting how the findings of complex network theory have very wide and important applications in genetics, ecology, communications, economics, and sociology.

This book is a clear and informative introduction to cryptography and data protection - subjects of considerable social and political importance. It explains what algorithms do, how they are used, the risks associated with using them, and why governments should be concerned. Important areas are highlighted, such as Stream Ciphers, block ciphers, public key algorithms, digital signatures, and applications such as e-commerce. This book highlights the explosive impact of cryptography on modern society, with, for example, the evolution of the internet and the introduction of more sophisticated banking methods.

Canada is not one nation, but three: English Canada, Quebec, and First Nations. Yet as a country Canada is very successful, in part because it maintains national diversity through bilingualism, multiculturalism, and federalism. Alongside this contemporary openness Canada also has its own history to contend with; with a legacy of broken treaties and residential schools for its Indigenous peoples, making reconciliation between Canada and First Nations an ongoing journey, not a destination. Drawing on history, politics, and literature, this Very Short Introduction starts at the end of the last ice age, when the melting of the ice sheets opened the northern half of North America to Indigenous peoples, and covers up to today's anthropogenic climate change, and Canada's climate politics. Donald Wright emphasizes Canada's complexity and diversity as well as its different identities and its commitment to rights, and explores its historical relationship to Great Britain, and its ongoing relationship with the United States. Finally, he examines Canada's northern realities and its northern identities.
