Fundamentals of Computers has been specifically designed for anybody and everybody who wants to be familiar with basic concepts of computers. It is an ideal text for self-learning basic computer concepts (such as organization, architecture, input and output devices, primary and secondary memory) as well as advanced topics (such as operating systems, computer networks, and databases). The book also provides step-by-step tutorials to learn different applications such as Ms Word, PowerPoint and Excel. Since the computer is no longer confined to be used by engineers and scientists, the book can be useful for a broad spectrum of students, varying from non-computers background students enrolled in elementary courses on Information Technology and Computer Sciences to students enrolled in professional courses such as BTech, BBA, BCA and MCA. It is also a valuable reference for diploma courses and courses taught at the polytechnic level.
