Detailed explanation-1: -Until recently, there were basically two main flavors of Unix: System V (five) from AT&T, and the Berkeley Software Distribution (BSD). SVR4 is essentially a merge of these two flavors. OSF/1 from the Open Software Foundation was released in 1991 (as a direct competitor to System V) and may change this picture.
Detailed explanation-2: -Developed by Linus Torvalds, Linux is a product that mimics the form and function of a UNIX system, but is not derived from licensed source code. Rather, it was developed independently; by a group of developers in an informal alliance on the net.
Detailed explanation-3: -Linux is an operating system which was developed by Linus Torvalds in 1991. The name “Linux” originates from the Linux kernel. It is an open-source software which is completely free to use.
Detailed explanation-4: -Linux is a free, open source operating system, released under the GNU General Public License (GPL). Anyone can run, study, modify, and redistribute the source code, or even sell copies of their modified code, as long as they do so under the same license.
