That question was closed two years ago with a then default close reason:
"Questions must be relevant to professional system administration. Server Fault is dedicated to professional system and network administrators. End user and enthusiast questions are off-topic (contact your system administrator or hire a professional to help you out).
Your question appears to me as indeed one an end-user or enthusiast would ask because it reads as more about idle curiosity than a professional investigating an actual problem. With current Q&A standards I would still expect your question to end up closed by the community for more or less the same reason.
We now use a different default close reason that actually suggests asking instead on Superuser which caters to site computer enthusiasts and power users.
