Previously we explained what an Operating system (OS) is, its importance and how we use them daily.

Over the years, several major operating systems have emerged, each with its unique characteristics, purposes, and ownership. Let’s explore some prominent examples of operating systems, including their release dates, ownership, how they are used, and what sets them apart.


Release Date: The first version of Microsoft Windows was released in November 1985.

Ownership: Owned and developed by Microsoft Corporation.

Usage: Windows has become one of the most widely used operating systems worldwide. It powers personal computers, laptops, tablets, and servers. Windows offers a user-friendly graphical interface, extensive software compatibility, and a broad range of applications. It caters to various user needs, from casual users to professionals, and provides support for gaming, productivity, and multimedia tasks.

Key Differences: Windows differentiates itself through its wide hardware compatibility, extensive software ecosystem, and user-friendly interface. It offers regular updates, strong enterprise support, and integration with other Microsoft products and services.


Release Date: The first version of macOS, previously known as Mac OS X, was released in March 2001.

Ownership: Developed and owned by Apple Inc.

Usage: macOS is exclusively designed for Apple’s Macintosh computers. It provides a sleek and intuitive user experience, seamless integration with other Apple devices, and robust performance. macOS is widely used in creative industries, such as graphic design, video editing, and music production. It also offers a range of productivity and entertainment applications through the Mac App Store.

Key Differences: macOS distinguishes itself with its focus on hardware-software integration, polished user interface (UI), and robust security features. It provides a seamless ecosystem across Apple devices and offers exclusive features such as Continuity, iCloud, and the Siri virtual assistant.


Release Date: First released by Linus Torvalds in September 1991.

Ownership: Linux is an open-source operating system distributed under various licenses. It is developed collaboratively by a global community of developers and organizations. No one really owns Linux.

Usage: Linux has a wide range of applications, powering servers, desktop computers, embedded systems, and mobile devices (Android). It offers flexibility, security, and customization options, making it popular among developers, researchers, and tech enthusiasts. Linux distributions (distros) such as Ubuntu, Fedora, and Debian provide different user experiences and package management systems.

Key Differences: Linux sets itself apart with its open-source nature, providing users with the freedom to view, modify, and distribute the source code. It offers a wide range of distributions tailored for various purposes, and its strong emphasis on security and stability makes it a preferred choice for servers and specialized computing tasks.


Release Date: Android was initially released in September 2008.

Ownership: Owned and developed by Google, but it is an open-source platform.

Usage: Android is the most widely used operating system for mobile devices, including smartphones and tablets. It offers a rich ecosystem of applications, services, and customization options. Android devices provide features such as app multitasking, seamless integration with Google services, and access to the Google Play Store, which hosts a vast collection of apps and games.

Key Differences: Android’s key differentiator is its focus on mobile devices and touch-based interfaces. It provides extensive customization options, supports a broad range of hardware devices, and offers integration with Google services such as Gmail, Google Maps, and Google Assistant.

It’s important to note that Android modified version of the Linux kernel.


Release Date: iOS was first released in June 2007 alongside the original iPhone.

Ownership: Developed and owned by Apple Inc.

Usage: iOS exclusively powers Apple’s mobile devices, including iPhones, iPads, and iPods. It offers a seamless and secure ecosystem, with a focus on usability, privacy, and performance. iOS provides access to the Apple App Store, offering a vast selection of applications tailored for Apple devices. It is widely used for tasks such as communication, productivity, gaming, and entertainment.

Key Differences: iOS stands out with its hardware-software integration, optimized performance, and a strong emphasis on privacy and security. It offers a consistent user experience across Apple devices, along with exclusive features such as FaceTime, iMessage, and Siri.

These major Operating Systems have shaped the computing landscape. Windows and macOS dominate the desktop market, with Windows offering broad compatibility and software support, while macOS emphasizes integration with Apple’s ecosystem. Linux provides flexibility and customization options, while Android and iOS cater to the mobile market, with Android focusing on customization and hardware diversity, and iOS emphasizing performance, security, and integration with Apple services.

Understanding the differences between these operating systems helps users make informed decisions based on their specific needs and preferences.
