Читать книгу Mastering Linux System Administration - Richard Blum - Страница 15

If you've never worked with Linux, you may be confused as to why there are so many different versions of it available. You've probably heard various terms such as distribution, LiveDVD, and GNU when looking at Linux packages, and may have been confused. Wading through the world of Linux for the first time can be a tricky experience. This chapter takes some of the mystery out of the Linux system before you start working on commands and scripts.

For starters, these four main parts make up a Linux system:

 The Linux kernel

 The GNU utilities

 A user interface

 Application software

Each of these four parts has a specific job in the Linux system. Figure 1.1 shows a basic diagram of how the parts fit together on top of the computer hardware to create the overall Linux system.

This section describes these four main parts in detail and gives you an overview of how they work together to create a complete Linux system.
