An operating systems is an essential component to run any computer. It manages your computer’s hardware, software, memory, and processes. Simply put, the operating system allows users to communicate with the computer without having to learn the computer language. You cannot do anything on your computer unless you install the operating system.
Since the OS manages all the hardware and the software components on the system, it has to do a pretty hectic job all the time. More often than not, there are a number of programs running simultaneously on the computer. These programs need to access their share of system storage, memory, and central processing units. This is when the operating system comes into action as it coordinates with all running processes to ensure they get what they need.
Operating systems come preloaded on the computer you buy; however, you can upgrade the version of the OS with the latest one. According to https://setapp.com/, you can downgrade the OS to the previous versions as well; however, make sure that the version you select is eligible to receive support and security updates from the manufacturer.
Modern OS uses GUI (Graphical User Interface) that lets you use the various elements using the combination of text and graphics such as menus, buttons, icons, etc.

The three majorly used operating systems include Windows, Linux, and macOS. In this article, we will discuss on all these operating systems to help you understand how they are different from each other and which one is appropriate for you.
Microsoft developed the Windows operating system in 1985 to run personal computers. The first version was launched as an extension of the existing MS-DOS (Disk Operating System). For the first time in history, Microsoft allows its users to navigate virtual desktops visually through graphical elements. The users get the opportunity to display the content of the electronic files and folders using a mouse rather than typing commands.
Various versions of the Windows operating system include MS-DOS, Windows 1.0-2.0, Windows 3.0-3.1, Windows-95, Windows-98, Windows-2000, Windows-XP, Windows Vista, Windows-7, Windows-8, Windows-10, Windows-11. With the release of XP in 2001, Microsoft brought together all the packages of the OS under a single banner to offer multiple editions for home users, multimedia developers, businesses, and others.
Microsoft released the initial build of Windows 11 in July 2021 to the Windows Insider Program Beta channel before bringing it to the public.
Linux is a family of an open-source OS that allows anyone around the world to modify and distribute the operating system under General Public License (GPL). This means that anyone can run, study, modify and distribute the source code and can sell copies of the modified Linux version.
Open-source programs like Linux are different from proprietary programs like Windows as the latter can only be modified by its manufacturer. Linux is free, and you can choose from a wide collection of versions or distributions. Most servers run on the Linux operating system as it is easy to customize and modify.
macOS, previously referred to as OS X, is the operating system introduced by Apple in 1984. All Macintosh computers or Macs come pre-installed with macOS. Since Apple computers are more expensive, the market share of the OS is way smaller than Windows, the most popular operating system of current times.
Various versions of macOS include OS X 10.0 (Cheetah), OS X 10.1 (Puma), OS X 10.2 (Jaguar), OS X 10.3 (Panther), OS X 10.4 (Tiger), OS X 10.5 (Leopard), OS X 10.6 (Snow-Leopard), OS X 10.7 (Lion), OS X 10.8 (Mountain Lion), OS X 10.9 (Mavericks), OS X 10.10 (Yosemite), OS X 10.11 (El Capitan), macOS 10.12 (Sierra), macOS 10.13 (High Sierra), macOS 10.14 (Mojave), macOS 10.15 (Catalina), macOS 11 (Big Sur), and the to be released macOS 12 (Monterey).
