I'm struggling to come up with the proper word to describe this concept. Like if I want to talk about whether a process is a 32-bit process or a 64-bit process, I want to talk about its ______?

"Bitness?" I don't know. "Bit size?"

Sorry if this isn't the correct StackExchange site for this, I wasn't sure which one to post in.

  • The word for applications most commonly used in my experience is "64-bit" or 32-bit" . That is normally what I see. – John Mar 22 at 17:40

    I've seen people use "bitness" to communicate this. As in, "the bitness of this application matters, and it can only run on 32-bit system" – music2myear Mar 22 at 17:46
  • "Width" is the word I'd use. (Though what do I know?) – Hot Licks Mar 22 at 18:37
  • I would prefer bititude; bitness with attitude. Or, if there are only two choices, 32 and 64, you can call one little and the other big and just use those as labels. – John Lawler Mar 22 at 19:18

    @JohnLawler - I suppose there's always "bitterness". – Hot Licks Mar 22 at 19:41

The number of bits is the word size of the CPU, however I believe that you are referring to the architecture, which is a wider concept.

  • Specifically, the word size of the architecture. – The Photon Mar 22 at 21:39
  • True. I made the assumption that since the author of this question apparently didn't know they probably meant this, but you're right let's upgrade the answer – Rémy Mar 22 at 22:01
  • Ah! I think word size is exactly what I meant! I couldn't think of it. Thank you. – Grandclosing Mar 25 at 16:49
  • However, 64-bit versions of Windows can run both 32- and 64-bit applications; older, 32-bit versions of Windows could run both 32- and 16-bit applications. The question as stated is looking for a word to describe the bitness of a process, not the platform. – gatkin Mar 29 at 13:21
  • Well, the word size of the code has to be implemented in the CPU, but it's still the word size – Rémy Mar 30 at 12:49
