Selecting an Operating System

The fact that you’re reading this book means you want to learn about the Linux operating system (OS). To begin this journey, you must first understand what an OS is and what type of OS Linux is. This chapter is therefore devoted to these basic issues.

In this chapter, we describe what an OS is, how users interact with an OS, how Linux compares with other OSs with which you may be familiar, and how specific Linux implementations vary. Understanding these issues will help you find your way as you learn about Linux and switch between Linux-based and other systems.
