How would a specific date, such as april 27, 2015, be represented as an absolute date?

To solve for the absolute data, the base or beginning date will need to be set. Once the beginning data has been established we can see how many days there were between the beginning and end dates.

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
