Interesting tid-bits

Did You Know?

  • a BIT is the smallest unit of data - it is either on (1) or off (0), never anywhere in between
  • "bit" is short for Binary digIT
  • 8 bits make one BYTE
  • "byte" is short for BinarY TErm
  • The bits in a byte are numbered right-to-left, starting with 0
  • The number of each bit corresponds to the power of two it represents:
    • 20=1
    • 21=2
    • 22=4
    • 23=8
    • 24=16
    • 25=32
    • 26=64
    • 27=128
  • To calculate the value represented by a byte, add the powers of two for all the ones: 0010 0101 = 32 + 4 + 1 = 37
  • When two bytes are grouped together the first byte represents higher powers of 2 (28 through 215)
  • The first byte in a pair is called the high byte or most signifibant byte. The second is called the low byte or least significant byte
  • There is also a word to refer to a group of four bits: NYBBLE (really!)
  • You can even refer to the most significant nybble (bits 4-7) or least significant nybble (bits 0-3)
  • Nybble isn't short for anything, it's just a play on words! (half a byte is a nybble!)
  • A single hexadecimal digit (0-F) represents one nybble:
    • 0000 = 0
    • 0001 = 1
    • 0010 = 2
    • 0011 = 3
    • 0100 = 4
    • 0101 = 5
    • 0110 = 6
    • 0111 = 7
    • 1000 = 8
    • 1001 = 9
    • 1010 = A (10)
    • 1011 = B (11)
    • 1100 = C (12)
    • 1101 = D (13)
    • 1110 = E (14)
    • 1111 = F (15)
