Chapter 8 Adding Disks Loops Run instructions again, and again, and again…. Check some condition If true, repeat 2 types of loops for loop while loop First, the variable used in loop condition must be initialized, then execution of the loop begins. media. YT Video 3:30. The hard drive is the primary long-term storage device used in personal computers. Hard drives are not volatile-even without power data remains stored on the drive. Hard drives come in three sizes for personal computers.
