Free derivatives of Unix can be easily downloaded via the Internet. This sets Unix apart from other proprietary operating systems like Microsoft Windows.
The different Unix versions and Unix-like operating systems available for download include FreeBSD, OpenBSD, Red Hat Fedora Linux, Debian Linux, Ubuntu Linux, and Sun Solaris.
Those who are new to Unix or Linux can still try these operating systems by using virtual machines, without worrying about existing data or OS being affected. The user can install his/her preferred Unix version inside the virtual machine to get a separate “computer” running inside the existing OS. These virtual machines can be set up with software such as Sun Microsystems’ VirtualBox, which is available as a free download.
Download FreeBSD Unix
The FreeBSD operating system is meant to be used on the following architectures:
- x86 machines, with Pentium or Athlon cores
- AMD64 compatible machines, which include Athlon 64, Opteron, and EM64T
- IA-64, PC-98
FreeBSD is an offshoot of BSD, the Unix version that was developed at the University of California, Berkeley.
Download OpenBSD Unix
The OpenBSD project developed the free, multi-platform 4.4BSD-based UNIX-like system. This system has the benefits of portability, standardization, and integrated cryptography. Binary emulation of programs from SVR4 (Solaris), FreeBSD, SunOS, Linux, BSD/OS and HP-UX is possible with OpenBSD Unix.
Download Solaris Unix
The Solaris OS exhibits good scalability, performance, and security on SPARC, Opteron, AMD, and Intel Xeon-based systems. The latest Solaris Unix version used exceptional technologies for facilitating robust computing infrastructures. The Solaris operating system integrates many popular open source applications, including Apache, Tomcat, and Secure Shell. Open source packages are available on this platform, cutting down the time needed for porting.
