Chapter 2 Summary

-Linux borrows heavily from the UNIX operating system, with which its creators were well versed. -Linux accesses many features and services through files and file-like objects. -Linux is a fully multi-tasking, multi-user operating system, with built-in networking and service processes known as daemons. -Linux is developed by a loose confederation of developers from all over the world, collaborating over the Internet, with Linus Torvalds at the head. Technical skill and a desire to contribute are the only qualifications for participating. -The Linux community is a far reaching ecosystem of developers, vendors, and users that supports and advances the Linux operating system. -Some of the common terms used in Linux are: Kernel, Distribution, Boot Loader, Service, Filesystem, X Window system, Desktop Environment, and Command Line. -A full Linux distribution consists of the kernel plus a number of other software tools for file-related operations, user management, and software package management.

What are the objectives of The Linux Foundation?

-The Linux Foundation aims to promote Linux, provide neutral collaboration and education -Improve Linux as a technical platform, and protect and support Linux development. -It sponsors the work of Linus Torvalds.

Chapter 1 Summary

Its work today extends far beyond Linux, fostering innovation at every layer of the software stack. -The Linux Foundation training is for the community and by the community. Linux training is distribution-flexible, technically advanced, and created with the leaders of the Linux development community. -There are three major distribution families within Linux: Fedora, SUSE and Debian. In this course, we will work with representative members of all of these families throughout.
