Microsoft Windows. Microsoft Windows is a series of graphical interface operating systems developed, marketed, and sold by Microsoft.
Version history The term Windows collectively describes any or all of several generations of Microsoft operating system products. These products are generally categorized as follows: Early versions Windows 2.0 was released in December 1987 and was more popular than its predecessor. Windows 2.1 was released in two different versions: Windows/286 and Windows/386. In addition to full Windows-packages, there were runtime-only versions that shipped with early Windows software from third parties and made it possible to run their Windows software on MS-DOS and without the full Windows feature set. Windows 3.0 and 3.1 Windows 3.1, made generally available on March 1, 1992, featured a facelift. Windows 9x The next major consumer-oriented release of Windows, Windows 95, was released on August 24, 1995.
Linux kernel. The Linux kernel is released under the GNU General Public License version 2 (GPLv2) (plus some firmware images with various non-free licenses), and is developed by contributors worldwide.
Day-to-day development discussions take place on the Linux kernel mailing list. The Linux kernel was initially conceived and created in 1991 by Finnish computer science student Linus Torvalds. Linux rapidly accumulated developers and users who adapted code from other free software projects for use with the new operating system. The Linux kernel has received contributions from thousands of programmers. History In April 1991, Linus Torvalds, a 21-year-old student at the University of Helsinki, Finland started working on some simple ideas for an operating system. He started with a task switcher in Intel 80386 assembly language and a terminal driver.
After that, many people contributed code to the project. In December 1991, Linux 0.11 was released. Fedora (operating system) Fedora /fɨˈdɒr.ə/ (formerly Fedora Core) is an operating system based on the Linux kernel, developed by the community-supported Fedora Project and owned by Red Hat.
Fedora contains software distributed under a free and open source license and aims to be on the leading edge of such technologies. Linus Torvalds, author of the Linux kernel, uses Fedora on all his computers. Fedora 20 with KDE Fedora uses the RPM package management system. Security is also important in Fedora with one specific security feature being Security-Enhanced Linux, which implements a variety of security policies, including mandatory access controls, and which Fedora adopted early on. Fedora comes installed with a wide range of software such as LibreOffice and Firefox.
Fedora is distributed in several different ways: Before Fedora 7, Fedora was called Fedora Core after the name of one of the two main software repositories - Core and Extras. Fedora is a trademark of Red Hat, Inc. Fedora Project Homepage. Debian. Debian (/ˈdɛbiən/) is an operating system composed of free software mostly carrying the GNU General Public License. The operating system is developed by an internet collaboration of volunteers aligned with The Debian Project.
Debian systems can use either the Linux kernel (known as the Debian GNU/Linux distribution), the FreeBSD kernel (known as the Debian GNU/kFreeBSD distribution) or, more recently, the GNU Hurd kernel (more precisely, the GNU Mach microkernel and its servers; known as the Debian GNU/Hurd distribution). The vital role the Debian project plays in free software is demonstrated by its advancement of development and security patches relating to its strong participation in CVE compatibility efforts. Ubuntu (operating system) Development of Ubuntu is led by Canonical Ltd., a company based on the Isle of Man and owned by South African entrepreneur Mark Shuttleworth.
Canonical generates revenue through the sale of technical support and other services related to Ubuntu. The Ubuntu project is publicly committed to the principles of open source development; people are encouraged to use free software, study how it works, improve upon it, and distribute it. GNOME (the former default desktop) supports more than 46 languages. For increased security, the sudo tool is used to assign temporary privileges for performing administrative tasks, allowing the root account to remain locked, and preventing inexperienced users from inadvertently making catastrophic system changes or opening security holes. PolicyKit is also being widely implemented into the desktop to further harden the system through the principle of least privilege.
Linux Mint provides a more complete out of the box experience by including proprietary and patented software . [ 1 ] Linux Mint introduced its first release, named "Ada", in 2006. Its latest and 13th release is "Maya". [ edit ] History Linux Mint started in 2006 with a beta release called 1.0 "Ada". Version 2.0 "Barbara" was based on Ubuntu 6.10, using its package repositories and using it as a codebase . In 2008, Linux Mint adopted the same release cycle as Ubuntu and dropped its minor version number before releasing version 5 "Elyssa".
