Best UNIX Operating System

UNIX is an operating system that was created in the 1960s and has been constantly improved since then. We mean collecting applications that allow the computer to work by the OS. It is a dependable, multi-user, multi-tasking system for servers, PCs, and laptops. UNIX systems also have a GUI that is similar to Microsoft Windows and provides a user-friendly environment. However, UNIX knowledge is required for operations that are not covered by a graphical program or when no windows interface is accessible, such as in a telnet session. In this article, you will learn the best UNIX operating system with its features.

Oracle Solaris

Best UNIX Operating System

Sun Microsystems was the original developer to create a Unix-based operating system. It's also compatible with AT&T's System V and the BSD OS. SunOS was the first OS to break ground at Sun Microsystems. After getting its first-generation inspiration from BSD, this OS publication was released in 1982. The machines that ran this operating system were powerful, affordable, and reliable due to the Sun's use of SPARC because of scalable processor architecture. The version buildup of the operating system to 3.x with the name SunOS. SunOS with Solaris was identified as the operating system version 4.0.

The development of the operating system progressed significantly, and the introduction of SunOS 5.0 from Unix system V supplanted the BSD. It was released in 1992. Sun's Solaris 2.4 release supported both X86 and SPARC computers. These creations were derived from a single source code base. Oracle later purchased Sun Microsystems and ended the Open Solaris project.

FreeBSD is defined by the original BSD (Berkeley Software Distribution). FreeBSD is defined as a feature-complete OS. It is due to its well-known characteristics, which include full-fledged documentation, device drivers, tools, and a kernel. Engineers William Jolitz and Lynne Jolitz renamed the operating system 386BSD after adapting it to the 80386 CPUs.

FreeBSD is widely rumored to have played an important role in developing Apple OS. However, the success of 386BSD in the user's domain prompted a subset of these users to create FreeBSD. In November 1993, the first official version was launched. This operating system's functional design makes it suitable for various applications. As a result, it works well in both server and desktop environments.

Microsoft/SCO Xenix

Best UNIX Operating System

The Xenix Unix-based OS was under a Microsoft license, and it was discontinued during the late 1970s. The popularity of UNIX later influenced Microsoft, leading it to buy AT&T's license rights. It is still not widely known that Microsoft used to influence UNIX rights. Although, Microsoft was not directly involved in the commercialization of Xenix to specific clients.

Companies including Intel, IBM, and SCO were given commercial licenses to transfer the Unix operating system on their CPUs. Microsoft's competitive advantage was lost due to its split with AT&T. Later, Microsoft sold their UNIX rights to SCO, an interested company. SCO then embarked on a rebranded Xenix release and renamed it SCO UNIX. The last version of this OS was SCO UNIX V.2.3.4, released in 1991 because its development was halted.

SGI (Silicon Graphics) created the IRIX OS, which is now defunct. The functional purpose of the operating system was to run natively on MIPS servers and workstations. Its developmental inspiration is tied to BSD extensions, and UNIX System V. Its version up to IRIX 6.0 was compliant with UNIX 95, POSIX, and UNIX System V Release 4. It is well-known for its innovative use of the XFS file system. IRIX also supported Real-time graphics and disks. As a result, visualization vendors in the disciplines of science and animation found it handy. The IRIX operating system is also a pioneer in developing a desktop GUI. MIPS-based SGI products became obsolete when the world accepted X86 processors. The last version of IRIX was 6.5, which was released in 1998. After then, Silicon Graphics was taken over by Rackable Systems.
