actually by definition it is. bit is a voltage difference.

e: of course that would not be compatible with current 0 and 1 based systems.

That would just create 63 different kinds of bit. A bit can be either high or low. That is all.

the 0 and 1 are just imagination. they could just as well have values from 0 to 100 if there was 101 different voltage levels. there are no bits or 0/1s, just voltage levels.  In fact there was a time when PCs had more than 2 voltage levels, but the need of accurate measuring of voltages hit the cap in performance quite early. Its much faster to just measure if there is voltage or not.

'bit' is an abbrevation for BInary digiT.

Binary means that only two values can be presented. 1/0, high/low, etc. If more than high and low can be measured, it is not binary anymore, and thus, cannot be measured in bits. You cannot divide a bit into 63 voltage levels. You can only have 63 different kinds of bit by using equipment that will respond to one voltage level but not the others. If you want to convert more than one level into binary, you need to do an analogue-to-digital translation.

bit in its original definition is selector, which has function that can be defined differently. bit could very well be A or B, X or Y, someone just decided that we use binary system.

With lets say 3 voltage levels, the 'selector', bit etc. has 3 possible values, it could be anything, A-C or 0-2 or what ever is chosed for it. Nothing is forcing to use binary digits for bits.

...which is also what I've been taught in digital technology class. I don't see how you divide something that is worth one binary value into more than one piece without significantly changing its properties by making it non-base 2.

You miss the point I am saying, definitions change. Nowaways almost no one remembers the past meaning of it, just the fact that in modern CPUs the binary system is what is used. ATM bit is heavily related to binary, but that doesn't mean it was like that in the first place.

If we are 100% accurate, such things as bits don't even exist. They are just imaginary definitions to help us understand how logic processors work.

A computer does not understand anything else but a difference in voltage. It doesn't understand no voltage means 0 or that 3V would means 1 or that 5V would mean 2 before someone defines to it that it is like that. Hence whole definition is imaginary. In reality its just voltage levels.

I don't happen to have a source for this, but it is easy to understand even without one.

That is completely unrelated to this. A bit can represent two values. That's it. You can make 0V represent 00, 3V represent 01 and 5V represent 10 by doing an analogue-to-digital conversion, but that's about as close as you're gonna get with bits.

What would you call the X in this:

         - A
X       - B
         - C
         - D

I would use a two-bit system, calling A 00, B 01, C 10 and D 11.

Assuming that X has a value of B, X is equal to 01.

Now, what would you call the selector X. not make it like this which is what is used in binary system.

             -1
       -X   -0
   -X     
       -X   -0
             -1

^ How its done atm. But define the name of the X in the upper system.

Sorry, I'm not following you now.

you call the 2-way selector a bit, what would you call the 4.way selector if not a bit?

I would call it a value.

thats the funny part as a bit is selector in the 2-way system, and its a selector in the 4-way system. This is what I have been after. The definition is flexible.
