Units we must understand ( in computers )

  • Kilo     means one thousand
  • Mega  means one  million
  • Giga   means one  billion 
    • So when I say Giga byte (GB), that means one billion bytes
    • And when I say Giga Hertz (Ghz), that means one billion Hertz.
    • Can you tell what Mega byte means?
