"ICT, or information and communications technology (or technologies), is the infrastructure and components that enable modern computing. Although there is no single, universal definition of ICT, the term is generally accepted to mean all devices, networking components, applications and systems that combined allow people and organizations (i.e., businesses, nonprofit agencies, governments and criminal enterprises) to interact in the digital world. ICT is leveraged for economic, societal and interpersonal transactions and interactions. ICT permeates all aspects of life, providing newer, better, and quicker ways for people to interact, network, seek help, gain access to information, and learn. Besides its presence everywhere, Information and Communication Technology has an immense economic significance. The importance of communication measured by ICT in today's society is enormous, as it affects sectors such as education or relationships.
The Information and communication technologies (ICT) are those tools needed to process information, in particular the use of computers, communication devices and software applications to convert, store, protect, process, transmit and retrieve information from anywhere and at any time. ICT has drastically changed how people work, communicate, learn and live. Moreover, ICT continues to revolutionize all parts of the human experience as first computers and now robots do many of the tasks once handled by humans. For example, computers once answered phones and directed calls to the appropriate individuals to respond; now robots not only can answer the calls, but they can often more quickly and efficiently handle callers' requests for services.
ICT's importance to economic development and business growth has been so monumental, in fact, that it's credited with ushering in what many have labeled the Fourth Industrial Revolution. ICT also underpins broad shifts in society, as individuals en masse are moving from personal, face-to-face interactions to ones in the digital space. This new era is frequently termed the Digital Age.
It is intended to give students the skills and understanding to use computers in both their current and future lives. The book offers the ideal forum for students to apply these skills in a practical way, particularly in presenting task work and key assignments across the full spectrum of the curriculum. The achievable goals of developing accuracy, neatness and presentation skills generate a sense of pride in work done by students which enhances self-esteem and motivates students to maximize their potential in other aspects of the course and in their personal lives. The main objective of ICT is the empowerment and independence of individuals to improve society. The technological revolution has profoundly changed many aspects of everyday life, facilitating communication, socialization and the development of relationships at distances.
However, it is necessary to reflect on how the behavior, values and competencies of individuals, organizations and societies can be influenced, manipulated and guided by these technologies. This book has been designed for students with no formal or previous experience in Information Technology. It will provide an introduction to a range of practical skills and underpinning knowledge that will enable students to use computers confidently in their everyday lives. "
