    • Fundamental unit of computer file size
  • Byte
    • 8 bits = 1 byte
  • Kilobyte (KB) = 1000 bytes
    • e.g. this PowerPoint file 65KB
  • Megabyte (MB) = 1000 Kilbytes
    • e.g. 1 minute video (220 x 176 pixels) 8MB
  • Gigibyte (GB) = 1000 Megabytes
    • Video from DVD 6GB
  • Terabyte (TB) = 1000 Gigabytes
