Definition: "Millicurie" is a unit of measurement used in communication and information technology. It is defined as one thousandth of a byte, or one thousandth of a bit (bit). This makes it a very small amount of data that is typically used for transmitting signals over long distances. The term "millicurie" was introduced to describe the size of this unit in the 1970s and has since become widely recognized as a standard unit of measurement.
