Basics of Information Technology

The term “information technology” came about in the 1970s. Its basic concept, however, can be traced back even further. Throughout the 20th century, an alliance between the military and various industries has existed in the development of electronics, computers and information theory. Information technology “is the study, design, development, implementation and support of computer-based information systems to address real -world problems”. In other words, it is the science (and, indeed, some might even say the art) of working with computers in order to facilitate the easier and more efficient use of them by non-professionals and professionals alike. Networks are used for an incredible array of different purposes. In fact, the definitions above are so simple for the specific reason that networks can be used so broadly, and can allow such a wide variety of tasks to be accomplished. While most people learning about networking focus on the interconnection of PCs and other "true" computers, you use various types of networks every day. This book provides deep insight to various dimensions of issues relating to the subject.
