When asked what is the difference between a Windows OS, a Linux OS and a Unix OS

The easiest to define is the Windows OS. When you say “Windows OS” you are probably ====

Most of the desktop computing world did not see Microsoft Windows until the 3.x versions came out in the early 1990s/

Microsoft Windows generally refers to the desktop workstation or personal computer version of the graphical operating systems developed by Microsoft Corporation.

Consumer versions of Windows were originally designed for ease-of-use on a single-user PC

founded by Paul Allen and Bill Gates on April 4, 1975 develop and sell BASIC interpreters for the Altair 8800

it moved on to MS-DOS Microsoft Disk Operating System) is an operating system for x86-based personal computers

The kernel is a computer program that is the core of a computer's operating system

The Linux kernel was conceived and created in 1991 by Linus Torvalds[11] for his personal computer and with no cross-platform intention

Linux as an OS has raised

Free software movement activist and programmer Richard Stallman has often commented on the many interesting arguments in defining open source as it relates to the Linux OS.

“Linux, the kernel, is often thought of as the flagship of free software, yet its current version is partially non-free.” (1) https://www.gnu.org/philosophy/linux-gnu-freedom.html

Think of the Linux kernel as the core of an internal combustion engineer that was free to use in designing an automobile. Now you start to see the interesting mix of free versus commercial software in the various versions.

Red Hat Enterprise Linux (RHEL) is a Linux distribution developed by Red Hat and targeted toward the commercial market. Fedora is a Linux distribution developed by the community-supported Fedora Project sponsored by Red Hat.

Unix OS Unix primarily uses Command Line Interface. Different Versions of Unix are: AIS, HP-UX, BSD, Iris, etc.

Linux Performance is not an issue

Linux is an open source and is compatible with most hardware system

One day in the late 1960s, Ken Thompson, Dennis Ritchie and a few of their colleagues at AT&T Bell Labs decided to write a simpler version of Multics to run games on their PDP-7, and thus Unix was born. AT&T held the rights to the code, and licenses were expensive.

Meanwhile, in Berkeley, a number of academics were unhappy with the licensing situation and decided to create a version of Unix that didn't include any AT&T-licensed code. Thus in the early 1980s the Berkeley Software Distribution, or BSD, became a free variant of Unix. BSD first ran on Minicomputers such as PDP-11 and VAXen.

The designation “Linux” was initially used by Torvalds only for the Linux kernel. The kernel was, however, frequently used together with other software, especially that of the GNU project. This quickly became the most popular adoption of GNU software. In June 1994 in GNU's bulletin, Linux was referred to as a “free UNIX clone”,

no operating system will have support for every single piece of hardware out of the box,

Berkeley Software Distribution (BSD) was a Unix operating system derivative developed and distributed by the Computer Systems Research Group (CSRG) of the University of California, Berkeley, from 1977 to 1995. Since that time there have been numerous open-source Unix-like operating system descended from BSD Research Unix such as FreeBSD and OpenBSD.

Operating systems derived from the original Berkeley source code, such as FreeBSD and OpenBSD, are actively maintained.

OpenBSD is a free and open-source Unix-like computer operating system descended from Berkeley Software Distribution (BSD), a Research Unix derivative developed at the University of California, Berkeley. In late 1995
