Fundamental of Operating System Technology
Operating systems have been evolving through the years. In the following sections we will briefly look at this development. Since operating systems history call have been closely tied to the architecture of the computers on which they run, we will look at successive generations of computers to see what their operating systems were like. This mapping of operating system generations to computer generations is crude, but it does provide some structure where there would otherwise be none.

The emergence of the operating system as a software entity responsible for the management of hardware resources took place throughout the 1960s. Presently, the operating system is commonly regarded as a compilation of software programs that enable the operation and coordination of hardware components. An operating system may be defined as a comprehensive assemblage of software programs that are specifically developed to facilitate the efficient administration and synchronization of computer resources. There are several variants of operating systems, including UNIX, MS-DOS, MSWindows, Windows/NT, and VM. The comprehensive safeguarding of computer systems entails the implementation of software safeguards across several tiers. Within the realm of an operating system, it is important to establish a clear distinction between kernel services, library services, and application-level services. These three categories delineate discrete partitions inside the operating system. Applications are performed by processes, which are interconnected via libraries that offer shared functionality. The kernel plays a crucial role in enabling development by creating a communication interface with peripheral components. The kernel is responsible for handling service requests that are initiated by processes, as well as managing interrupts that are created by devices. The kernel, located at the nucleus of the operating system, is a meticulously crafted software intended to function inside a constrained state. The main responsibility of the system is to handle interruptions that arise from external devices, in addition to servicing requests and traps that are started by processes. In order to optimize the functionality of computer hardware, it is imperative to employ an Operating System that contains the capacity to recognize and establish connections with all hardware components, hence enabling users to effectively participate in productive endeavors. This part will mostly concentrate on the examination of the operating system, encompassing its progression and fundamental objective
