The book tries to give students of computer science and professional programmers a general understanding of operating systems--the programs that enable people to share computers efficiently. To make the sharing of a computer tolerable, an operating system must enforce certain rules of behavior on all its users. One would therefore expect the designers of operating systems to do their utmost to make them as simple, efficient, and reliable as possible. A number of operating systems made in the early 1960's had these characteristics; but in the late 1960's designers were often overambitious and built enormous systems with poor performance. I see no inherent reason why operating systems should not reach the quality of program construction found in present compilers; this will require an understanding of the principles common to all operating systems and a consistent use of safe methods of designing large programs. It is my hope that this book will give you a start in this direction. I assume that you are familiar with the basic structure of computers and programming languages and have some experience in writing and testing non-trivial programs. In a few cases a knowledge of elementary calculus and probability theory is also needed. THEM

本文介绍了三种流行操作系统的启动过程和功能的比较研究。 启动过程是操作系统执行此过程后必不可少的第一步，所有其他进程都有机会执行，所以我们可以说启动是第一个过程，因为所有其他操作系统进程都可以执行。 操作系统的主要目标是在许多程序之间共享计算机安装，对其资源提出不可预测的需求，这些资源被各种应用程序用来操纵许多其他资源。 有时它会产生一些不同的功能，这使得它们对应的操作系统独一无二。 在我们的工作中，我们展示了一些 Windows、MacOS 和 Linux 操作系统的特性比较，并指出了启动系统及其过程。
