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.
