Computer science is a field that is concerned with the study of the theory of computation and the design of software systems. It encompasses the use of algorithms for storing, manipulating and communicating digital information. Computer science is a broad field that spans diverse theoretical studies such as the study of algorithms and the limits of computation, as well as practical aspects of implementing computing systems in software and hardware. An integration of computer science and electronic engineering is required for developing computer hardware and software which is under the scope of computer engineering. This field encompasses the design of personal computers, supercomputers, individual microcontrollers and circuit design. Designing software, analog sensors, VLSI chips and operating systems, as well as using digital systems for the control and monitoring of electrical systems and robotics are some areas of focus in computer engineering. The ever-growing need of advanced technology is the reason that has fueled the research in the fields of computer science and engineering in recent times. The objective of this book is to give a general view of the different areas of these fields and their applications. Students, researchers, experts and all associated with computer science and engineering will benefit alike from this book.
