!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

When either X or Y is 1 and the other is 0 = No, but when X and Y are the same value = Yes, that’s an XNOR.
"Inclusive or" doesn't specifically mean "saying yes when someone asks an X or Y question".
Inclusive or is the general function that takes X and Y as inputs and returns true if either one of of X or Y is true. Which is in contrast to an exclusive or, which returns true if exactly one of X or Y is true, but not both. So the joke is "you expected this to be an exclusive choice between two options, but I interpreted it as an inclusive or and said yes, indicating that one or the other is true but without telling you which one".
If the answer is "no" to an inclusive or, then neither X nor Y is true: which cashes out to normality. Like "Do you want tea or coffee? -- No" means you want neither tea nor coffee. Whereas if the answer is "no" to an exclusive or, then it could be the same case where neither X nor Y is true, but it could also be because they're both true. So "Do you want tea xor coffee -- No" would be ambiguous between "I don't want either" and "I want tea AND coffee".
I'm pretty sure it's just plain "nor" but I don't know, I ain't no logician.
That would be a "NAND" Gate as far as I know.
Nand is not and
You need more info and the whole truth table. There’s a few functions of f(x,y) that would yield true when both x and y inputs are true. In general though, exclusive or (XOR) is common-use English “or”. Inclusive or (OR) is what you mention, and then the inverse of OR is NOR which may be what you are talking about or the inverse of XOR or XNOR or NORX depending on the textbook.
This is all digital logic stuff, and I’m not sure if logic involves in philosophy would use the same naming.
Exclusive and
