This chapter serves as an introduction to operating systems, outlining their role as intermediaries between users and computer hardware. The document outlines the history, types, objectives, and functions of operating systems, detailing their evolution from early batch systems to modern real time and distributed systems. An operating system is software that manages computer hardware resources and provides common services for computer programs. it acts as an intermediary between users and the computer hardware. The operating system is divided into a number of layers (levels), each built on top of lower layers. the bottom layer (layer 0), is the hardware; the highest (layer n) is the user interface.
