  How can werelate to the terms Bits and Bytes?“This computer has a 64-bit processor with 4 Gigabytes of RAM and 200 Gigabytes of hard disk space”“My parents played Atari (8-bit) and I play Nintendo (64-bit)”

  Bitbit = Froma shortening of the words “binary digit”the basic unit of information for computers1 or 0 are the only values
• 5.
  ByteByte = 8bitsEach keyboard character is stored as a ByteExample  A = 01000001

  How does acomputer processor understand bytes????The processor is made of zillions of Transistors. Transistor on = 1Transistor off = 0
• 9.
  9A transistor isa switch.
• 10.
  Switch on =1
• 11.
  Switch off =0
• 12.
  The ”A” existsas a pattern in eight transistors, where some are “turned on” (charged) and others are not.
• 13.
  Together these 8transistors make up one byte. Give this a shot…..The Binary Math Game

  UNITS  Big& Way Big BytesByte a grouping of eight bits for instance --> 0110 0001Kb (kilobyte) about 1000 bytesMb (megabyte) about one thousand Kb or one million bytesGb (gigabyte) about one thousand Mb or one billion bytesTb (terabyte) is about one thousand Gb or one trillion bytes
• 15.
  Terms for StorageCapacities 1 bit = 0 or 1 (b)8 bits = 1 byte (B)1 thousand bytes = kilobyte (KB)1 million bytes = megabyte (MB)1 billion bytes = gigabyte (GB)1 trillion = terabyte (TB)
