How to know your operating system

Knowing the specific version of your operating system (OS) is crucial for a variety of reasons. The latest versions often come with new features, enhanced security, and improved performance, while older versions might lack support or security patches. 

Identifying your OS version ensures that your device is compatible with the software you’re using, allows you to manage updates effectively, and bolsters security. This article will guide you through the steps to determine your OS version across iOS/iPadOS, Android, macOS, Windows, and Linux.
