Choosing an operating system is one of the most important decisions when buying or setting up a computer. The operating system controls how you interact with your computer, manages hardware and software, and provides the environment where applications run.
The three operating systems most people encounter are Windows, Linux, and macOS. Each has its own advantages, disadvantages, and ideal users.
Windows is widely used in homes, businesses, schools, and gaming. Linux is known for its flexibility, customization, and popularity among developers and IT professionals. macOS is designed specifically for Apple’s Mac computers and is known for its polished user experience and integration with other Apple devices.
But which one is best?
The answer depends on what you plan to do with your computer.
In this guide, we’ll compare Windows vs. Linux vs. macOS, looking at ease of use, hardware compatibility, software, gaming, security, customization, cost, performance, and more.
What Is an Operating System?
Before comparing the three operating systems, it helps to understand what an operating system actually does.
An operating system (OS) is the software that manages a computer’s hardware and provides a platform for applications to run.
When you turn on a computer, the operating system eventually takes control of the system and helps manage components such as:
- Processor
- Memory (RAM)
- Storage
- Keyboard and mouse
- Display
- Network connections
- Printers and other peripherals
The operating system also provides the interface you use to interact with the computer.
For example, when you open a web browser, save a document, install an application, or connect to Wi-Fi, the operating system is involved in making those actions possible.
Windows, Linux, and macOS all perform these basic functions, but they approach them differently.
