Protocols of Binary Addition:

• 0 + 0 = 0
• 0 + 1 = 1
• 1 + 0 = 1
• 1 + 1 = 0, Note: carry 1 to the next more significant bit

Binary Addition Derivation

Binary Equivalent

• 1 Nibble (or Nybble)  =  4 bits
• 1 Byte  =  2 nybbles  =  8 bits
• 1 Kilobyte (KB)  =  1024 bytes
• 1 Megabyte (MB)  =  1024 kilobytes  =  1,048,576 bytes
• 1 Gigabyte (GB)  =  1024 megabytes  =  1,073,741,824 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
•
