Study Notes

Operating System (O.S.)

An Operating System is an abstraction layer designed to facilitate hardware operation and enable access for users.
Composed of a kernel and system tools, facilitating the development of portable applications.
Key functions include resource management (memory), input-output management, file management, program management, and user interface support.

Linux History

1969: Creation of Unix by Ken Thompson at Bell Laboratories.
1970: Development of the C programming language alongside Unix adaptation for DEC PDP-11/20.
1974-1977: Free distribution of Unix sources to universities.
1978: Unix ownership transfers to AT&T, making sources paid.
1979: Birth of BSD Unix at the University of California at Berkeley.
1987: Launch of AIX by IBM and HP-UX by HP; introduction of the X Window graphical interface by MIT.
1991: Emergence of Linux, developed by Linus Torvalds, with the first release of Linux 0.1.

Linux and GNU

Linux began as a UNIX kernel project initiated by Linus Torvalds.
The GNU Project, initiated by Richard Stallman in the early 1980s, aimed to create a complete free software system.
Linux integrates GNU utilities, leading to the complete operating system often referred to as GNU/Linux.

Free Software Concept

Defined by the freedom to execute, study, modify, redistribute, and improve software.
Emphasizes that "free" refers to freedom, not price; access to source code is essential.
Developed under the General Public License (GPL), allowing users to make modifications and share them.

Characteristics of Linux

Free and open-source, allowing modifications.
Supports collaborative development and fine process control.
Multi-user and multi-tasking capabilities; network-oriented functions.
Alters the conventional software landscape: alternatives exist for many proprietary applications (e.g., Mozilla Firefox as an alternative for Internet Explorer).
Strengths include security (minimal viruses), built-in firewalls, and extensive documentation.

Linux Distributions

Numerous Linux distributions exist, varying by user-friendliness, software integration, community support, desktop environment, and package management.
Notable distributions include Linux Mint, Red Hat, Ubuntu, Fedora, OpenSUSE, Debian, Arch Linux, CentOS, and Kali.
Commonality among distributions lies in the Linux kernel and a core set of commands, despite differing philosophies and objectives.
