Researching the history of computers is a good troubleshooting technique. true or false?

Yes very much so! You could learn previous mistakes/bugs/etc and find solutions to fixing them and avoiding getting them. As well as much more. History is always a fun subject for anything, really in my opinion.

true

is it right ? :)

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)
