I know this may depend on computer manufacturers, but I think it's interesting to ask here: hopefully someone knowledgeable can shed some light on this issue.
This question is restricted to Windows machine only.
Assuming that the users don't change the computer name, how likely-- or unlikely-- it is for two computers to have exactly the same name? Like two "LAPTOP-G76WER0O" ( I made that up) floating around in the market, one in China, another in US.
On paper, if the default name is generated randomly, then the chances of two laptop name colliding is slim; there are 36 alphanumeric possible permutation for just one character, and there are at least 8 of them usable ( reserving the front few for Laptop-), so the combination is 36^8=2.8211099e+12. I doubt whether one can hit on such a humongous number by chance.
But I don't know how the computer name assignment is being done, maybe some algorithm ensures that name collision does happen?
ChatGPT/Gemini told me that the chances of name collision is slim, based on the above logic. So here am I asking real human.
