Binary Numbers
  • Mr. Lowen / Mr. Garton
  • Network Systems 1

2
Binary Numbers
  • Computers store data this way
  • magnetic charges- either there or not
  • impulse 1 no impulse 0
  • data saved magnetically onto diskette
  • Analogies
  • Coins (either heads or tails)
  • Lights (either on or off)
  • Morse code (dots or dashes)

3
Binary Numbers
  • Based on the digits 0 and 1
  • Grouped in sets of eight bits
  • Bits binary digits
  • EXAMPLE
  • 00001001 the number 9
