An operating system is considered to be the backbone of any system. Without an operating system, the user and system cannot interact. It acts as a mediator between both of these. We mainly have three kinds of operating systems, namely, Linux, MAC, and Windows. To begin with, MAC is an OS that focuses on the graphical user interface and was developed by Apple, Inc, for their Macintosh systems. Microsoft developed the Windows operating system. It was developed so as to overcome the limitation of the MS-DOS operating system. Linux is UNIX like a source software and can use an operating system that provides full memory protection and multi-tasking operations. It is an open d by anyone.
Linux is a group of Unix-like operating systems based on the Linux kernel. It belongs to the family of free and open source software. It is usually packaged in a Linux distribution. Linux was first released in the year 1991. It is most commonly used for servers, however, a desktop version of Linux is also available.
Debian, Fedora, and Ubuntu are popular Linux distributions. We do have RedHat Enterprise Linux and SUSE Linux Enterprise Server (SLES) that are available as commercial distributions of Linux. As it is freely redistributable, anyone can modify and create variations of source code.
