What is an operating system?
An operating system is the main software that runs a computer or phone, such as Windows, macOS, iOS or Android.
An operating system (OS) is the core software that runs a device and lets other apps work. Windows and macOS run most computers, and iOS and Android run most phones. Web servers usually run Linux. The operating system and its version can change how a website looks or behaves, mainly through the browser that runs on it. Keeping your OS updated brings security fixes.
Why it matters for your business: When you report a website problem, include your device, operating system and browser. It helps our team reproduce what you see.
