This book is intended for students in Computer Science Engineering, Information Technology, Electrical and Mechanical engineering. It emphasizes on the integration of hardware, software, algorithms and programming languages etc. to enhance the performance of the system. The material covered in the book is suitable for one semester course on “Computer Organization & Assembly Language” and another semester course on “Computer Architecture”. It focuses on a basic syllabus on digital logic design and an introductory course on high- level computer language.
Computer architecture deals with the design of computers, data storage devices, and networking components that store and run programs, transmit data, and drive interactions between computers, across networks, and with users. It uses parallelism and various strategies for memory organization to design computing systems with very high performance. It requires strong communication between computer scientists and computer engineers, since they both focus fundamentally on hardware design. The main take away from this book is in building the undertaking yourself. 
In this book, we have constructively raised the fundamentals of Computer Organization & Assembly Language with all the necessary concepts with respect to building real time applications.
