# Operating Systems I spend way too much time on the computer that I should at least take some notes on the different kinds that I spend that time on. As of 2020 there are three major computer operating systems (OS’s): Windows, macOS, Linux. Windows is the workhorse: if you had to select the computer at random more than likely it's running some form of Windows. Apple machines are running some version of a proprietary Macintosh computer system, which allow for people to have their own niche applications and fixing to make their computer an extension of themselves. My dad was always annoyed that I like to use these machines but ¯\\\_(ツ)\_/¯. Finally, Linux comes in various distributions and is the computer scientist’s choice in OS and what my dad wished that I would use more often. But when you run into a problem then it’s all up to you to fix it and I am just too lazy for that. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://nkintc.gitbook.io/brainless/steam/technology/operating-systems.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
