You would have to borrow three bits because borrowing only two would result in four and two of those cannot be used. 2n²-2 gives four addresses, one with all 0s and one with all 1s in binary form. Those two cannot be used so an additional bit would have to be borrowed to get at least three usable subnets.
A group of four bits is known as a nibble.
One nibble, or nybble, is equal to four bits.

Four bytes represent 32 bits. 32 bits represent 4,294,967,296 possibilities.
If you are asking what is four (4) in the binary system, the answer is 100.
This depends upon the language. In some languages the first bits may represent an address or label. Most assembly languages the first byte or two is an op code. Four bits is pretty small for an address--that is only half a byte. Four bits on the Intel 4004 chip represent a "word."
its called a Nibble
There are eight bits in a byte or two nibbles in a byte meaning there are four bits in a nibble.
awls bits
Not in computing. A bit is a single entity. A nibble is four bits. A byte is eight bits.
The original 'Maria Theresa' dollars had divisions on them which made it easy to break them into eight pieces.
