operating systems


Fedora

 Fedora is an RPM-based, general purpose Linux distribution, developed by the community-supported Fedora Project and sponsored by Red Hat. Fedora's mission statement is: "Fedora is about the rapid progress of Free and Open Source software." One of Fedora's main objectives is not only to contain free and open source software, but also to be on the leading edge of such technologies.

Ubuntu

 Ubuntu is a Linux distribution for desktops, laptops, and servers. It has consistently been rated among the most popular of the many Linux distributions. Ubuntu's goals include providing an up-to-date yet stable operating system for the average user and having a strong focus on usability and ease of installation.

CentOS

 CentOS CentOS is a freely-available Linux distribution that is based on Red Hat Enterprise Linux (RHEL), which itself is based on Fedora Linux. This rebuild project strives to be 100% binary compatible with the upstream product and, within its mainline and updates, not to vary from that goal.

FreeBSD

 FreeBSD is a Unix-like free operating system descended from AT&T UNIX via the Berkeley Software Distribution (BSD) branch through the 386BSD and 4.4BSD operating systems. It runs on Intel x86 family (IA-32) PC compatible computers, DEC Alpha, Sun UltraSPARC, IA-64, AMD64, PowerPC, ARM and NEC PC-98 architectures along with the Microsoft Xbox. FreeBSD has been characterized as "the unknown giant among free operating systems." It is not a clone of UNIX, but works like UNIX, with UNIX-compliant internals and system APIs. FreeBSD is generally regarded as reliable and robust. FreeBSD is the free operating system listed most often in Netcraft's list of the 50 web servers with the longest uptime.

Solaris

 Solaris is a free Unix-based operating system introduced by Sun Microsystems in 1992 as the successor to SunOS. Solaris is known for its scalability, especially on SPARC systems, as well for being the origin for many innovative features such as DTrace and ZFS. Solaris supports SPARC-based and x86-based workstations and servers from Sun and other vendors, with efforts underway to port to additional platforms.
