If you mean the operating system(OS), let's say you have multiple mining rigs, you might need a linux based OS to make it easier for you to
manage them. But if you only have a couple of rigs and then run them, windows might be fine for you so the list I'm going to go over is first we
have windows and after windows we have linux based mining OS so that would include Hive OS or Rave OS and all the different linux based mining OS.
Maybe Linux is more recommended for Os mining, Hive Os is also one of the leading OS for Mining, Linux is more ideal for computers with low or old resources, and for users who don't have or have limited Internet potential.
But Awesomeminer is also superior in use for mining, you can try it.
