one bit is equal to how many nibble
Nibble In computing, a nibble (occasionally nybble or nyble to match the spelling of byte) is a four-bit aggregation,[1][2] or half an octet. It is also known as half-byte[3] or tetrade.[4][5] In a networking or telecommunication context, the nibble is often called a semi-octet,[6] quadbit,[7] or quartet.[8][9] A nibble has sixteen (24) possible values. A nibble can be represented by a single hexadecimal digit and called a hex digit.[10]
Kilobyte The International System of Units (SI) defines the prefix kilo as 1000 (103); per this definition, one kilobyte is 1000 bytes.[1] The internationally recommended unit symbol for the kilobyte is kB.[1]
