The Operating System (OS) is the most essential program of all without which it becomes absolutely cumbersome to work with a computer. It is the interface between the hardware and us (i.e., computer user), making it much easier and more pleasant to use the hardware. Familiarizing ourselves with the operating system and its services helps us to utilize the computer in a more effective manner and to do our jobs well. With this in mind, we need to know the operating system’s services and how to make use of them. The operating system itself has to be written so that it can exploit the hardware in the most efficient way possible. Much effort has been put into this matter. Since the computer was invented in the 1940s, many scientists have strived to make this software user-friendly and efficient for the operation of the hardware. The net result is truly a masterpiece that utilizes a multitude of innovations and the fruit of much hard work.
In this book, we first discuss a less clarified aspect of the operating system, namely the way the operating system takes over the hardware and becomes the real internal owner of the computer. This knowledge, plus a macro view of what the operating system does and how it does it, provides an insight and advantage to make better use of the overall facilities of the computer. It also provides the basis for a more comprehensive understanding of the complex aspects of the operating system. Then, we elaborate on concepts, methods, and techniques that are employed in the design of operating systems.
