Protocols of Binary Multiplication:

• 0 x 0 = 0
• 0 x 1 = 0
• 1 x 0 = 0
• 1 x 1 = 1, Note: no carry or borrow bits

Binary Equivalent

• 1 Nibble (or Nybble)  =  4 bits
• 1 Byte  =  2 nybbles  =  8 bits
• 1 Kilobyte (KB)  =  1024 bytes

Binary Numbering System

• system digits:  0 and 1 (Zero and One)
• Bit (short for binary digit):  a single binary digit
• LSB (least significant bit):  the rightmost bit
• MSB (most significant bit):  the leftmost bit
• Upper Byte (or nybble):  the right-hand byte (or nybble) of a pair
• Lower Byte (or nybble):  the left-hand byte (or nybble) of a pair
