True — with a caveat.
If you mean the mathematical/logical Boolean type, it has exactly two values (true and false). But in real programming and data systems booleans often have other "values" or representations:
- SQL / three-valued logic: TRUE, FALSE, UNKNOWN (NULL).
- Nullable booleans (e.g., C# Nullable<bool>) can be true, false, or null.
- C uses integers for truth: 0 is false, any non‑zero is true.
- JavaScript has many truthy/falsy values (""/0/null/undefined/NaN are falsy) even though the Boolean type itself is true/false.
- Serialized forms sometimes use "1"/"0", "yes"/"no", "on"/"off", etc.
So strictly two values for a Boolean in theory, but in practice you’ll often encounter other values or representations depending on the system.
