What is Solaris Operating System?

Solaris is a Unix-based operating system developed by Sun Microsystems, now owned by Oracle Corporation. It was first released in 1992 and quickly gained popularity for its scalability, reliability, and advanced features. Over the years, Solaris has undergone significant enhancements, making it a preferred choice for various enterprise-level applications.

A Brief History of Solaris

The history of Solaris traces back to the early 1980s when Sun Microsystems started developing SunOS, the precursor to Solaris. SunOS was initially based on the BSD Unix operating system but later transitioned to the UNIX System V Release 4 (SVR4) with the launch of Solaris 2.0 in 1992. Since then, Solaris has seen several major releases, each incorporating innovative technologies and improvements.
