Bharat Operating System Solutions


Know About BOSS

Bharat Operating System Solutions (BOSS) is a Linux distribution developed by NRCFOSS (National Resource Centre for Free/Open Source Software). This software is also known by the acronym BOSS GNU/Linux or simply BOSS Linux. The latest version of this operating sysem, BOSS GNU/Linux Version 3.0, was released in September 2008.
This software package has been described as India's own PC operating system and as the most meaningful product to come out of the Indian software industry.
The software has also been endorsed by the Government of India for adoption and implementation in a national scale.
BOSS GNU/Linux is a "LSB certified" Linux distribution: The software has been certified by The Linux Foundation for compliance with the Linux Standard Base standard.
BOSS GNU/Linux is derived from Debian. Debian uses the Linux kernel (the core of an operating system), but most of the basic operating system tools in Debian come from the GNU Project; hence the appendages GNU/Linux to Debian and BOSS. Debian GNU/Linux provides more than a pure operating system: it comes with over 18733 packages. BOSS GNU/Linux includes nearly all of these packages.
The product is a free software in the sense in which the term is used by the Free Software Foundation, and it is distributed under GNU General Public License.[10]
The latest desktop version of BOSS GNU/Linux is fully localised to eighteen Indian languages.
