What OS (Operating System) do I have?
What OS you have is useful information if someone is helping you solve technical problems on your computer or mobile device. Support teams need to know what operating system you've got so that they can give you instructions or help specific to your set-up.
The instructions to help you might be different depending on whether you're using Windows, Mac or Linux, or maybe iOS or Android (on your phone). So it's very helpful to know what OS (operating system) you're using.
