Linux is a computer operating system and its kernel. It is one of the most prominent examples of free software and of open-source development: unlike proprietary operating systems such as Windows and Mac OS, all of its underlying source code is available to the public and anyone can freely use, modify, improve, and redistribute it.

Kernel
The kernel is the core piece of the Linux operating system.
- Current (stable version): 2.6.20.2 (2007-03-09)[1]
The kernel manages the resources of the Linux OS; such as the following:
- File management
- Multitasking
- Memory management
- I/O management
- Process management:
/proc/ - Device management:
/dev/ - Networking support (including IPv4 and IPv6)
- Virtual memory, shared libraries, demand loading, etc.
The kernel decides who will use these resources, for how long, and when.

Distributions
Linux is predominantly used as part of a Linux distribution (commonly called a 'distro'). These are compiled by individuals, loose-knit teams, and various professional organizations. They include additional system software and application programs, as well as certain processes to install these systems on a computer.
My favourite distributions include:
- SuSE — my primary operating system since 1999. (see also: openSUSE)
- Mandriva
- Damn Small Linux (DSL) — A live CD designed for MiniCD with a hard drive install option.
