Assuming each operating system installed requires 2GB of RAM, what is the minimum amount of physical RAM that will need to be installed in the host system to meet the requirements of this scenario

3gb i believe

that would be my answer.

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)
