Summary
COMPUTER FUNDAMENTALS Computer science is a discipline that spans thew and practice. It requires thinking both in abstract terms and in concrete terms. The practical side of computing can be seen everywhere. Nowadays, practically everyone is a computer user, and many people are even computer programmers. Getting computers to do what you want them to do requires intensive hands-on experience. But computer science can be seen on a higher level, as a science of problem solving. Computer scientists must be adept at modeling and analyzing problems. They must also be able to design solutions and verify that they are correct. Problem solving requires precision, creativity, and careful reasoning. This book presents fundamental contributions to computer science as written and recounted by those who made the contributions themselves. This book is an introduction to the fundamentals of computer, linking its scientific aspects with practical applications. It is addressed to both readers who wish to learn Hardware and Software and those seeking to understand computer devices. The book begins with how numeric and character data are represented in a computer, how various input and output units function, how different types of memory units are organized and how data is processed by the processor.
