In the last few decades, the developments in Operating System (OS) have brought to focus the concepts of process concurrency, low power design, security, etc. along with refined and matured approach for the conventional topics like processes, interrupts, semaphores. However, illustrations of these concepts and techniques in the program design form are either confined to research articles or not given due importance in many textbooks. A system programming subject like OS should cover program design illustrations and guidance along with emphasis on new concepts. The major focus of this book is to explain the OS concepts and techniques with illustrations of program design. It is the outgrowth o...
