Revise: Units of Data StorageA nibble contains 4 bits, and a byte contains 8 bits, so two nibbles make one byte.
A group of four bits.
Group binary digits into nibbles from the right. If necessary, add zeros on the left, not the right.
Use A–F for nibble values 10–15: for example, 1101 becomes D, not the two digits 13.
