A binary number has a value of what?

Answer 1

I'm not entirely sure what you're asking.

In one sense, "binary number" means a quantity that can take on only two possible values. "True" or "False," for example. "On" or "off." "1" or "0."

You can, however, represent other values using a "binary" system. Computers store ordinary numbers like "42" in a binary format. In that case, you'd have something like "0010 1010".
