Ubuntu\u00c2\u00a0is a\u00c2\u00a0free and open source\u00c2\u00a0operating system\u00c2\u00a0and\u00c2\u00a0Linux distribution\u00c2\u00a0based on\u00c2\u00a0Debian.\u00c2\u00a0Ubuntu is offered in three official editions: Ubuntu Desktop\u00c2\u00a0for\u00c2\u00a0personal computers, Ubuntu Server for\u00c2\u00a0servers\u00c2\u00a0<\/span>and the\u00c2\u00a0cloud,\u00c2\u00a0and Ubuntu Core\u00c2\u00a0for\u00c2\u00a0Internet of things\u00c2\u00a0devices. New releases of Ubuntu occur every six months, while\u00c2\u00a0long-term support\u00c2\u00a0(LTS) releases occur every two years.<\/p>\n

Ubuntu is built on\u00c2\u00a0Debian’s architecture and infrastructure, and comprises Linux server, desktop and discontinued phone and tablet operating system versions.\u00c2\u00a0Ubuntu releases updated versions predictably every six months,\u00c2\u00a0and each release receives free support for nine months (eighteen months prior to 13.04)\u00c2\u00a0with security fixes, high-impact bug fixes, and conservative, substantially beneficial low-risk bug fixes.\u00c2\u00a0The first release was in October 2004.<\/p>\n

Ubuntu is produced by\u00c2\u00a0Canonical\u00c2\u00a0and the community in a\u00c2\u00a0meritocratic\u00c2\u00a0governance model. Canonical provides free guaranteed security updates and support for each Ubuntu release, starting from the release date and until the release reaches its predesignated\u00c2\u00a0end-of-life\u00c2\u00a0(EOL) date.\u00c2\u00a0Canonical generates revenue through the sale of premium services related to Ubuntu.<\/p>\n

Ubuntu is the most popular\u00c2\u00a0operating system\u00c2\u00a0for the\u00c2\u00a0cloud and is the reference operating system for\u00c2\u00a0Open Stack.<\/p>\n

A\u00c2\u00a0default\u00c2\u00a0installation of Ubuntu contains a wide range of software that includes\u00c2\u00a0LibreOffice,\u00c2\u00a0Firefox,\u00c2\u00a0Thunderbird,\u00c2\u00a0Transmission, and several lightweight games such as\u00c2\u00a0Sudoku\u00c2\u00a0and\u00c2\u00a0chess.\u00c2\u00a0Many additional software packages are accessible from the built-in\u00c2\u00a0Ubuntu Software\u00c2\u00a0(previously\u00c2\u00a0Ubuntu Software Center) as well as any other\u00c2\u00a0APT-based\u00c2\u00a0package management\u00c2\u00a0tools. Many additional software packages that are no longer installed by default, such as\u00c2\u00a0Evolution,\u00c2\u00a0GIMP,\u00c2\u00a0Pidgin, and\u00c2\u00a0Synaptic, are still accessible in the repositories still installable by the main tool or by any other\u00c2\u00a0APT-based\u00c2\u00a0package management\u00c2\u00a0tool. Cross-distribution\u00c2\u00a0snap packages\u00c2\u00a0and\u00c2\u00a0flatpaks\u00c2\u00a0are also available,\u00c2\u00a0that both allow installing software, such as some of Microsoft’s software, in most of the major Linux operating systems (such as any currently supported Ubuntu version and in Fedora).<\/p>\n

Ubuntu operates under the\u00c2\u00a0GNU General Public License\u00c2\u00a0(GPL) and all of the application software installed by default is free software. In addition, Ubuntu installs some hardware drivers that are available only in binary format, but such packages are clearly marked in the restricted component.<\/p>\n

Ubuntu’s goal is to be secure “out-of-the box”. By default, the user’s programs run with\u00c2\u00a0low privileges\u00c2\u00a0and cannot corrupt the operating system or other users’ files. For increased security, the\u00c2\u00a0sudo\u00c2\u00a0tool is used to assign temporary privileges for performing administrative tasks, which allows the\u00c2\u00a0root account\u00c2\u00a0to remain locked and helps prevent inexperienced users from inadvertently making catastrophic system changes or opening security holes.\u00c2\u00a0PolicyKit\u00c2\u00a0is also being widely implemented into the desktop. Most network ports are closed by default to prevent hacking.\u00c2\u00a0A built-in firewall allows end-users who install network servers to control access. A\u00c2\u00a0GUI\u00c2\u00a0(GUI for Uncomplicated Firewall) is available to configure it.\u00c2\u00a0Ubuntu compiles its packages using\u00c2\u00a0GCC\u00c2\u00a0features such as\u00c2\u00a0PIE\u00c2\u00a0and\u00c2\u00a0buffer overflow protection\u00c2\u00a0to\u00c2\u00a0harden\u00c2\u00a0its software.\u00c2\u00a0These extra features greatly increase security at the performance expense of 1% in\u00c2\u00a032-bit\u00c2\u00a0and 0.01% in\u00c2\u00a064-bit.<\/p>\n

Ubuntu also supports full disk encryption\u00c2\u00a0as well as encryption of the home and Private directories.<\/p>\n
