Linux is a fast-growing operating system, it is inexpensive and highly flexible. Almost all the key organizations in IT industry including Google use variations of Linux to power their servers. Linux is also a major player in the small and mid-sized server field, and it’s an increasingly viable platform for workstation and desktop use as well. By understanding Linux, you’ll increase your standing in the job market. Even if you already know Windows or Mac OS and your employer uses these systems exclusively, understanding Linux will give you an edge when you’re looking for a new job or you’re looking for a promotion.
The Linux Professional Institute (LPI) has developed its LPI-1 certification as an introductory certification for people who want to enter careers involving Linux. The exam is
meant to certify that an individual has the skills necessary to install, operate, and troubleshoot a Linux system and is familiar with Linux-specific concepts and basic hardware.
The purpose of this course is to help you pass the LPIC-1 exams (101 and 102).

applications, networking, and security, those are the topics that are emphasized in this
book. You’ll learn enough to get a Linux system up and running and to configure it for
many common tasks.
